Leave the repairs and renovations of condominiums and apartments in Machida City, Tokyo to Kakeru Koumuten Co., Ltd.!
Large-Scale Repairs for Condominiums, Apartments, and Buildings in Machida City, Tokyo
To owners, management associations, and management companies considering large-scale repairs for condominiums, apartments, and buildings in Machida City, Tokyo.
Kakeru Koumuten Co., Ltd. is an exterior repair company that handles everything from the installation of temporary scaffolding to substrate repairs, exterior painting, tile repairs, sealing, waterproofing of rooftops and balconies, and roofing work, all managed and performed by our own team. We have undertaken numerous large-scale repairs and exterior renovations for apartments, condominiums, and commercial facilities in Machida City.
- On-site surveys and estimates are completely free (we welcome competitive estimates)
- All work from temporary scaffolding to exterior and roofing work is managed by our own team
- Our own scaffolding team handles sites in Machida City, from condominiums to apartments
- Consultations for partial repairs or emergency measures for leaks are also possible
- Cost Estimate / For condominiums, the cost per unit is approximately 750,000 to 1,500,000 yen (about 70% fall within this range according to the Ministry of Land, Infrastructure, Transport and Tourism’s survey for the fiscal year 2021, with the most common range being 1,000,000 to 1,250,000 yen. This amount excludes consumption tax and common temporary costs). For wooden apartments, the estimate is around 2,000,000 to 4,000,000 yen per building.
- Estimated Cycle / 12 to 15 years. However, the determining factor is not the number of years but the condition of deterioration.
- Particularly Relevant in Machida City / There are 521 buildings and 23,729 units of condominiums in the city (based on the Machida City condominium actual condition survey as of January 1, 2017), with about 86% of privately supplied units being less than 30 years old at that time. Given that some time has passed since the survey, it is believed that more buildings are approaching the time for their next large-scale repairs when adjusted for current construction years. A large part of the city is in the Tama Hills, with an elevation difference of 25 to 361.6 meters, making it essential to check for slopes, retaining walls, and areas at risk of landslides. Housing complexes such as UR and JKK have many buildings, leading to larger scaffolding and temporary plans. Landscape planning notifications also apply to repainting in the same color, with guidelines including heights of 10 meters or more, more than 9 units for collective housing, and a total floor area of over 1,000 square meters.
- Available Funds / The official page of Machida City does not confirm any municipal programs that subsidize the costs of large-scale repair work or deterioration diagnosis itself. Support for condominiums in the city includes seismic retrofitting promotion subsidies and consultation windows and seminars. If requirements are met, there is a one-third reduction special measure for fixed asset tax (Machida City tax. Work completed by March 31, 2027, with applications within three months after completion), interest subsidies from Tokyo (applications for the second period of fiscal year 2026 are accepted until February 19, 2027), and consideration of public financing combinations.
- Tips for Avoiding Mistakes / At least three competitive estimates. Compare not only the amounts but also the quantities, methods, and materials.
Large-scale repair work we can handle in Machida City, Tokyo
Large-scale repairs are not just “exterior painting” or “waterproofing”; they are comprehensive repairs to the entire building while scaffolding is in place. At Kakeru Koumuten, we can handle all of the following work with our own team, ensuring clear responsibility and coordination of the process.
| Type of Work | Main Contents |
|---|---|
| Temporary Scaffolding Work | Installed by our own scaffolding team using our own scaffolding materials. We handle mesh sheets, protection, and fall prevention measures. |
| Substrate Repair Work | Crack repairs, injection of floating mortar and tiles, explosion (exposed rebar) repairs, resin mortar repairs for missing parts. |

| Others | Replacement of rain gutters, rooftop and exterior wall inspections using drones, leak investigations using thermal imaging, and preliminary investigations of asbestos-containing materials. |
Scope of Large-Scale Repairs Determined by Building Diagnosis
It is not always necessary to perform all the above works. The extent of the work will be determined based on the results of the building diagnosis. At Kakeru Koumuten, we conduct a free on-site survey to confirm the items below, compile them into a deterioration diagnosis report with photos, and propose the scope of work.
| Diagnosis Area | Main Investigation Method | Scope of Work Determined by Diagnosis Results |
|---|---|---|
| Exterior Wall (Painted Surface) | Visual inspection, checking the width of cracks and the condition of the paint film | Method and quantity of crack repairs, specifications for painting (whether to repaint or paint after removing the existing paint film) |
| Exterior Wall (Tile Surface) | Tap test. High areas checked with a drone | Scope and estimated quantity for injection and replacement, whether clear waterproofing is necessary |
| Sealing | Checking for cracks, shrinkage, peeling, and hardening | Whether to replace or add to the existing seal, scope of joints to be worked on |
| Rooftop, Balcony, Shared Corridor | Checking for blisters or breaks in the waterproof layer, puddles, and the condition of drains | Full renovation or partial repair, method (urethane waterproofing, PVC sheet waterproofing, long sheet), whether drain renovation is necessary |
| Leak Areas | Investigation using thermal imaging camera and drone | Identification of the cause and priority areas for repair |
| Metal Parts, Roof, Accessories | Checking for rust, corrosion, lifting, and cracking | Whether painting is sufficient or if component replacement or overlay installation is necessary |
| Site and Surroundings | Checking retaining walls, slopes, trees, access routes, and parking | Planning for scaffolding and scope of temporary work |
Reasons Kakeru Koumuten is Chosen for Large-Scale Renovations in Machida City, Tokyo
The reason why we can be entrusted with large-scale repairs in Machida City is due to our “initiatives that cannot be imitated by other companies in large-scale repair work”, which have received high praise from many customers.
1. Equipment Specialized for Exterior Renovations
Kakeru Koumuten is equipped with the following warehouses and material storage areas to provide low-cost, high-quality exterior wall painting and waterproofing work for large-scale repairs. We have established five bases centered around Yokohama City for material storage and showrooms.
In-house Scaffolding Materials
We own the scaffolding materials necessary for temporary scaffolding required for large-scale repairs and can assemble the scaffolding ourselves.
By performing scaffolding work with our own scaffolding team instead of outsourcing, we can cut costs for scaffolding work and provide quick and flexible responses.
We own approximately enough scaffolding materials for 100 single-family homes!
Storage of Materials in Our Large Warehouse
We store paints and substrate repair materials used for exterior renovations. By ordering a large quantity of materials at once, we can procure materials at a lower cost! Additionally, we always have stock available, allowing us to provide swift responses in emergencies!
In-house Waste Separation
Various waste materials such as leftover paint, metal, and wood are generated during large-scale repairs. Kakeru Koumuten reduces waste disposal costs by sorting and recycling waste materials in-house.
Showroom Dedicated to Exterior Renovations

In the showroom, not only can you have meetings, but you can also check actual samples and colors of exterior materials. Color simulations for exterior wall painting and heat insulation tests using a heat insulation testing machine are also available!
2. Cost Reduction through In-House Management and Construction
One of Kakeru Koumuten’s major strengths is in-house management and construction.
By managing everything from inquiries to project completion in a unified system, we can keep costs down while providing high-quality large-scale repairs. Additionally, one representative will handle everything from the estimate to project completion. Since the sales representative and construction management representative do not change, smooth communication is possible.
We can handle everything from temporary scaffolding installation to exterior wall painting, substrate repair, waterproofing work, and tile repairs with complete in-house construction! Those with specialized knowledge and experience will conduct inspections and actual construction for each process!
3. Obtaining Various Permits and Skilled Workers
We have obtained construction business licenses and permits for industrial waste collection and transportation! We also have nationally certified sheet metal and painting technicians on staff, and we are confident in our construction techniques. We can also handle large-scale roofing work for factories! We have qualified personnel for asbestos work supervisors and building material asbestos surveyors, so we can handle asbestos-containing roofing materials and preliminary surveys as well.
4. Warranty and Aftercare

Most large-scale repair works, including “painting work,” “substrate repair work,” and “waterproofing work,” come with a warranty!
Aftercare maintenance is available every year, and we send out notification DM each year.
5. Flexible and Quick Response
Our company is equipped to handle various troubles and situations related to apartments and condominiums.
We can also address exterior walls and rooftops that cannot be checked from high places using drones! During rain leak investigations, we can use a thermal imaging camera to help identify the cause of leaks!
We will respond according to your wishes. We also accept emergency measures for sudden leaks! We will respond quickly to urgent requests or emergencies!
6. Staff Development
Our staff create various models for skill improvement and conduct practical training. Since different sites require various processing and techniques, we regularly provide skill enhancement education to ensure each staff member can respond appropriately. We also educate on points to be careful of and areas to check in each process of large-scale repair work.
7. Consideration for Residents and Neighbors

During large-scale renovation work, we will not only notify residents and greet nearby residents, but also install a notice board at the entrance to display the construction schedule and announcements! Additionally, we will thoroughly educate visitors on proper manners to minimize any inconvenience to residents and neighbors.
8. Strict Quality Control

Each process will be inspected by a responsible person, and detailed construction photos will be taken. We will use film thickness inspection devices and check sheets to ensure that there are no oversights in the inspections. During exterior wall painting and waterproofing work, we will check the number of used paint cans to confirm that the specified amount of paint is being used, and by ordering paint in-house, we will prevent construction defects in advance. Of course, we will also take photos of the used paint and report them.
9. Exterior Wall Painting Color Simulation
9-1 Self Color Simulation

The simulations we create can be done using actual photos of your apartment or building!Simulations can also be done on your smartphone or computer. By simulating and then applying a two-tone color or making a change in image, we hope to enhance the stylish appearance and contribute to an increase in occupancy rates! Of course, we can also arrange paint samples for actual color confirmation.
* In Machida City, the notification for landscape planning also applies to repainting with the same color (the scale guideline is approximately 10m or higher in height, 9 or more units for apartment buildings, and a total floor area of 1,000㎡ or more, etc. It varies by area). Notifications must be submitted at least 30 days before starting the work. It is also necessary to check the district regulations such as district plans. Having a color simulation screen will help facilitate explanations to the general meeting, neighbors, owners, and residents.
9-2 Confirm the actual color with a test paint!
You can order samples of the paint you are considering and conduct a test paint on your exterior wall. By doing a test paint, you can confirm the actual color and gloss!
9-3 Exterior Renovation Simulation
Exterior simulations for apartments and condominiums are also possible!
・Exterior wall color simulation (two-tone colors are also possible)
・Simulation for applying metal siding
・Simulation using accent materials such as cornices and louvers
・Simulation for roof painting and roof replacement work
With the exterior renovation simulation, you can minimize the risk of failure in changing the image! We hope that renovating the appearance of apartments and condominiums will help increase occupancy rates.
Cost Estimate for Large-Scale Repairs in Machida City, Tokyo
The cost of large-scale repairs varies significantly depending on the size of the building, the degree of deterioration, the scope of work, and the materials used. First, refer to the national average based on public statistics, then to our company’s cost estimates based on construction performance by scale, and finally to examples of unit prices for each project.
The national average for condominiums is 750,000 to 1,500,000 yen per unit
According to a survey conducted by the Ministry of Land, Infrastructure, Transport and Tourism, which aggregated 818 construction cases (FY 2021), approximately 70% of the costs for large-scale repairs are concentrated in the range of 750,000 to 1,500,000 yen per unit, with the most common price range being 1,000,000 to 1,250,000 yen. Note that this survey’s amounts do not include consumption tax and common temporary construction costs, so they differ from the current total construction costs including tax.
| Construction Cost per Unit | Percentage | Construction Cost per Unit | Percentage |
|---|---|---|---|
| Up to 750,000 JPY | 15.1% | 1,250,000 to 1,500,000 JPY | 17.4% |
| 750,000 to 1,000,000 JPY | 24.7% | 1,500,000 to 2,000,000 JPY | 9.1% |
| 1,000,000 to 1,250,000 JPY | 27.0% (most common) | Over 2,000,000 JPY | 2.8% |
Source: Ministry of Land, Infrastructure, Transport and Tourism “Survey on Large-Scale Renovation Work for Condominiums in FY2021” (200 companies, 818 cases) *Amounts do not include consumption tax or common temporary costs. Percentages may not total 100% due to rounding and non-responses.
Breakdown of Construction Costs (What the Money is Spent On)
| Category | Composition Ratio | Main Contents |
|---|---|---|
| Construction-related Work | 60.3% | About half for exterior walls, about one-third for waterproofing. Substrate repair, tiles, painting, waterproofing |
| Temporary Work | 22.8% | Scaffolding, mesh sheets, protective coverings, etc. (does not include common temporary costs) |
| Miscellaneous Expenses | 10.3% | Site management costs, general management costs, statutory welfare costs, etc. (9.5%), insurance premiums for large-scale renovation defect insurance (0.8%) |
Source: Ministry of Land, Infrastructure, Transport and Tourism “Survey on Large-Scale Renovation Work for Condominiums in FY2021” (Second survey of large-scale renovation work. Overall average is construction-related 59.0%, temporary 22.3%, miscellaneous expenses 9.9%). *The total does not equal 100% because equipment-related work, exterior works, and others are included. This is an average value and not a criterion for judging the appropriateness of individual estimates.
Cost Estimates by Building Size (Scaffolding, Substrate Repair, Exterior Wall Painting, Waterproofing, Sealing as a Whole)
| Type and Scale of Building | Estimated Cost | Estimated Construction Period |
|---|---|---|
| Wooden Apartment (2 stories, 6-10 units) | 2,000,000 – 4,000,000 JPY | 3 – 5 weeks |
| Steel and RC Apartment (3 stories, 10-20 units) | 4,000,000 – 9,000,000 JPY | 1 – 2 months |
| Mixed-Use Building / Small Apartment (4-5 stories) | 5,000,000 – 15,000,000 JPY | 1.5 – 3 months |
| Medium-Sized Apartment (30-50 units) | 20,000,000 – 50,000,000 JPY | 3 – 5 months |
| Large Apartment (100 units or more) | Around 100,000,000 JPY or more | 6 months or more |
*The above estimates are based on Kakeru Koumuten’s construction records and may vary depending on the presence of roofing work, steel work, plumbing, etc. For apartments, please also consider the amount calculated by multiplying the national statistics (750,000 – 1,500,000 JPY per unit) by the number of units as a guideline.
Breakdown of Costs for Temporary Works, Substrate Repairs, Exterior Walls, and Waterproofing
The estimate for large-scale repairs is broadly divided into “Temporary Works,” “Substrate Repairs,” “Sealing,” “Exterior Wall Painting,” “Waterproofing,” and “Miscellaneous Expenses.” Before comparing total amounts, please check what each item includes, how much, and at what cost.
| Item | What to Check in the Estimate |
|---|---|
| Building Prerequisites | Structure (wooden, steel, RC), number of stories, number of units, exterior wall area, and waterproofing area. Also confirm whether the area is based on drawings or actual measurements. |
| Common Temporary Works and Scaffolding | Area and unit price of scaffolding, contents of mesh sheets, protection, temporary toilets, etc. According to the Ministry of Land, Infrastructure, Transport and Tourism’s survey for Reiwa 3, temporary works such as scaffolding account for about 20% of construction costs (excluding common temporary costs). |
| Substrate Repairs | Quantities and unit prices for repair methods such as cracks, lifting, and spalling. Since these items are not finalized until scaffolding is set up, please confirm whether it is estimated quantities or actual settlement, and the settlement method if quantities increase or decrease. |
| Sealing | Whether it is a replacement or additional sealing, length of work (m), and material name. |
| Exterior Wall Painting | Painting area (㎡), manufacturer name, product name, grade of paint, number of coats, and scope of ancillary parts. |
| Waterproofing | Area for each part such as rooftops, balconies, and common corridors, construction method, material name, and whether drain renovations are included. |
| Inspection and Reporting | Inspections for each process, construction photos, and whether a completion report and warranty are included. |
| Miscellaneous Expenses | Contents and proportions of site management fees, general management fees, and statutory welfare expenses. According to the Ministry of Land, Infrastructure, Transport and Tourism’s survey for Reiwa 3, these average about 10% of construction costs, but can vary depending on the size and conditions of the building, so there is no uniform standard. |
| Tax Classification | Whether the amounts are tax-inclusive or tax-exclusive. Since companies may display this differently, be sure to standardize before comparing total amounts. |
Examples of Unit Prices for Repair Work
| Repair Method | Materials Used | Cost |
|---|---|---|
| Tile Replacement | Existing Similar Tiles | per piece / 2,000 JPY〜4,000 JPY |
| Repair of Tile and Mortar Lifting Areas | Epoxy Resin Injection | per square meter / 3,000 JPY〜5,000 JPY (Varies depending on the degree) |

| Temporary Scaffolding | In-house Owned Scaffolding Materials (Wedge Type) | per square meter / 700 JPY〜1,000 JPY |
*Costs and warranty periods vary based on shape, quantity, substrate condition, and type of materials. If you would like a detailed estimate, please feel free to contact us. Estimates are completely free.
Select Paint and Waterproofing Grades Based on “Years Until Next Repair”
“Good paint does not equal the right choice.” The best way to choose is to align when the next major repair will be with the lifespan of the materials to avoid waste.
| Grade | Estimated Lifespan | Suitable Cases |
|---|---|---|
| Silicone / Radical Control Type | 10-16 years | Buildings that are maintained every 12-15 years. A good balance of cost and performance. The lifespan varies by product, so choose a product specification that matches the cycle. |
| Fluorine | 16-20 years | Buildings that want to set the next repair after 15 years, high-rise or complex-shaped buildings where scaffolding costs are high. |
| Inorganic | 18-22 years | Buildings that want to suppress dirt adhesion. Effective for suppressing moss and algae on the north side or poorly sunlit areas. |
| Urethane Waterproofing (Roof) | 8-15 years | Complex-shaped rooftops, when wanting to renovate while utilizing the existing waterproof layer. Mid-term inspections and repairs, such as re-coating the top coat, are prerequisites. |
| PVC Sheet Waterproofing | 20-25 years | Wide and simple-shaped rooftops. Short construction time. |
| Asphalt Waterproofing | 15-20 years | Rooftops planned for long cycles. The cost per instance will increase. |
*The estimated lifespan is a general guideline and may vary depending on sunlight, location, and substrate condition. Choosing paints with anti-algae and anti-mold properties can improve durability in shaded and humid areas.
Guidelines for Repair Reserve Funds and Options When Insufficient
The Ministry of Land, Infrastructure, Transport and Tourism’s guidelines indicate the estimated repair reserve fund on a monthly basis per unit area. Additional charges are required if there is a mechanical parking lot.
| Building Size (Less than 20 Stories) | Monthly Estimate (Average) | Range Covering Two-Thirds of Cases | Conversion for 70㎡ |
|---|---|---|---|
| Building Floor Area Less than 5,000㎡ | 335 JPY/㎡ | 235-430 JPY/㎡ | Approximately 16,500-30,100 JPY |
| 5,000-10,000㎡ | 252 JPY/㎡ | 170-320 JPY/㎡ | Approximately 11,900-22,400 JPY |
| 10,000-20,000㎡ | 271 JPY/㎡ | 200-330 JPY/㎡ | Approximately 14,000-23,100 JPY |
| Over 20,000㎡ | 255 JPY/㎡ | 190-325 JPY/㎡ | Approximately 13,300-22,750 JPY |
Source: Ministry of Land, Infrastructure, Transport and Tourism “Guidelines on Repair Reserve Funds for Condominiums” (Reiwa 6, June Revision, PDF) / National average is 13,378 JPY per unit per month (Reiwa 5 Fiscal Year Comprehensive Survey of Condominiums)
In the Reiwa 5 Fiscal Year Comprehensive Survey of Condominiums, 36.6% of management associations reported that “the repair reserve fund is insufficient compared to the plan.” There are four main options when there is a shortfall.
| Options | Considerations and Points to Note |
|---|---|
| ①Adjusting the Construction Schedule | Based on deterioration diagnosis, postpone less urgent work to the next time. However, it is essential to distinguish between work that can and cannot be postponed, as delaying waterproofing and tile fall prevention measures will ultimately be more costly. |
| ②Reviewing the Scope and Specifications of Work | Revising paint grades, changing from full renovation to partial renovation, etc. Please consider this separately from “apparent cost reductions” that skip processes. |
| ③Utilizing Subsidies and Tax Systems | Subsidies for earthquake resistance promotion in Machida City, reductions in fixed asset tax, subsidies for energy-saving renovations, etc. (to be detailed later). The reduction in fixed asset tax is a system that lowers the tax amount for each unit owner, and does not directly increase the repair funds of the management association. |
| ④Increasing Reserve Funds, Borrowing, and One-Time Payments | In addition to considering increasing the repair reserve fund at the general meeting, the Housing Finance Agency’s loan for condominium common area renovations requires no collateral. Interest rates can be lowered by obtaining management plan certification. |
Subsidies, Tax Systems, and Loans to Check for Large-Scale Renovations in Machida City, Tokyo
Based on the official page of Machida City, there were no city subsidies for large-scale renovations or deterioration diagnosis of condominium units. The city’s consultation window page also does not mention subsidies for large-scale renovation work or deterioration diagnosis, and the Housing Division is indicated as the contact point. The city’s support for condominiums mainly focuses on earthquake resistance promotion subsidies for buildings constructed under old standards, consultation windows, and seminars. For large-scale renovations, we will consider a combination of tax systems, loans, and national and Tokyo Metropolitan systems. The main options available are broadly categorized into five types. The eligibility and application status of these systems may change during the fiscal year, so please be sure to confirm with our company or each contact point before contracting or starting work. (As of October 14, 2026)
| Type | Details |
|---|---|
| ① Support for Machida City | Seismic retrofitting promotion subsidy for old earthquake-resistant condominiums (advisor dispatch, seismic diagnosis, design, and renovation), consultation desk and seminars related to management. The contact point is the Housing Division. |
| ② Tax Incentives | Reduction of fixed property tax under the condominium longevity promotion tax system (in Machida City, fixed property tax is a municipal tax, and the reduction rate is one-third. You must report to the Property Tax Division within three months after the completion of the work). |
| ③ Management Plan Certification System | A certification system that serves as an entry point for tax incentives and lower loan interest rates. Condominiums in Machida City apply through the Housing Division (Machida City) using the condominium management center’s procedural support system. |
| ④ Purpose-specific Construction Subsidies | Energy-saving (windows, insulation, etc.), seismic measures, etc. Confirm and utilize those that can be incorporated into large-scale repairs from national and Tokyo Metropolitan Government projects. The subsidy information from Machida City does not include subsidies for windows, insulation, or for collective housing. |
| ⑤ Loans and Interest Subsidies | Loan for renovation of common areas of condominiums from the Japan Housing Finance Agency, interest subsidies from Tokyo Metropolitan Government (subsidy for condominium improvement work). |
① Support for Condominiums in Machida City (Seismic Retrofitting and Consultation Desk)
The main support that Machida City provides for condominium management associations has been organized based on what can be confirmed on the city’s official page. None of these are systems that directly cover the costs of large-scale repair work.
| Seismic Retrofitting Promotion Subsidy | Eligibility | Management associations of condominiums in the city, specifically for buildings constructed before May 31, 1981 (Showa 56), that are old earthquake-resistant structures. Conditions include having two or more unit owners, having residential parts, being fire-resistant or quasi-fire-resistant structures, and generally being three stories or more above ground. |
|---|---|
| Advisor Dispatch | The dispatch cost is fully subsidized, with a maximum of 50,000 yen per instance, and up to 10 times per management association. |
| Subsidy for Seismic Diagnosis, Design, and Renovation | Seismic diagnosis is two-thirds of the lesser amount between the unit price based on the total floor area (3,670 yen, 1,570 yen, or 1,050 yen per square meter) and actual costs. Seismic design is two-thirds of the lesser amount between 2,000 yen per square meter and actual costs. Seismic renovation work is 51,700 yen per square meter for areas of 1,000 square meters or more (86,400 yen for special methods), and 39,900 yen for areas under 1,000 square meters, two-thirds of the lesser amount between this and actual costs. Each applies once per building. |
| Application Timing and Acceptance | It is not stated on the city’s page whether application is required before contracting. It is advised to consult with the Housing Division in advance. The application period for fiscal year 8 (Reiwa 8) is also not listed, so please confirm at the contact point (the page was last updated on April 1, 2026). |
| Contact Point | Machida City Urban Development Department Housing Division 042-724-4269 |
| Consultation and Seminars on Management | The Housing Division introduces related organizations and holds condominium management seminars several times a year. For specialized consultations on condominiums in Tokyo (consultations by lawyers and architects), applications can be made through the Housing Division in Machida City. The dispatch of advisors from the Tokyo Disaster Prevention and Urban Development Center is fee-based (03-6427-4900). |
|---|---|
| Consultation Desk for Large-Scale Repair Orders | In response to the announcement by the Fair Trade Commission on September 28, Reiwa 8, the city’s page (updated October 2, 2026) provides information on the Housing Renovation and Dispute Resolution Support Center (estimate check service – free. 03-3556-5147) and the Condominium Management Center (consultation on building and facility maintenance. 03-3222-1519). Points to consider when placing orders include utilizing external experts, confirming the neutrality of design consultants, and adding clauses for collusion penalties, as advised by the Ministry of Land, Infrastructure, Transport and Tourism. |
* The information page for Machida City’s subsidies (for global warming measures) only lists the city’s one-time payment for household fuel cells (Enefarm) (application period has ended), and no city subsidies for windows, insulation, or for collective housing could be confirmed. The city’s asbestos countermeasures page also did not confirm any city subsidies for investigation or removal work. Since the application status may change, please check the latest handling at the counter before applying.

② Tax System for Promoting the Longevity of Condominiums (Reduction of Fixed Asset Tax)
If you carry out large-scale repairs (such as exterior painting, floor waterproofing, and roof waterproofing as a single project) on a condominium that meets certain requirements, the fixed asset tax amount for the building will be reduced in the following year (up to the equivalent of 100㎡ per unit; urban planning tax is not included). The reduction rate is determined by local ordinances. In Machida City, the fixed asset tax is a city tax, and according to Machida City’s information, the fixed asset tax amount for the house in the year following the completion of the work will be reduced by one-third (in the 23 wards of Tokyo, the fixed asset tax is a metropolitan tax, and the reduction rate is one-half).
| Main Requirements of the National System | A condominium that has been built for over 20 years, has more than 10 units, and where the floor area of the residential exclusive part is more than half of the total exclusive area / has previously carried out exterior painting, floor waterproofing, and roof waterproofing at least once each / a condominium that has received certification of its management plan, which has raised the amount of the repair reserve fund (average amount for the entire planning period) from below the certification standard to above the standard after September 1, 2021, or a management association that has received administrative advice and guidance based on the Condominium Management Improvement Act, resulting in the long-term repair plan conforming to national standards. |
|---|---|
| Implementation Deadline of the National System | From April 1, 2023, to March 31, 2027 (Machida City’s information indicates the same period). |
| Treatment in Machida City | The reduction rate is one-third (up to the equivalent of 100㎡ per unit. The urban planning tax is not reduced). The declaration deadline is within three months after the completion of the work, and if the deadline is missed, a reason for the late submission must be provided. The declaration should be submitted to the Machida City Finance Department, Asset Tax Division, Housing and Depreciable Assets Section (2nd floor of City Hall, 042-724-2118). Since each unit owner must submit a declaration for the condominium, the management association should compile and submit it, and in that case, individual numbers do not need to be included. For advice and guidance on management plan certification and reserve funds, the Urban Development Department, Housing Division (042-724-4269) is the contact point. |
| Main Submission Documents | Certificate of large-scale repair work (work carried out from April 1, 2023, to March 31, 2027), past work certificate (work carried out before March 31, 2023), and a certificate of all matters (to prove that there are more than 10 units). For certified management plan condominiums, a management plan certification notification and a certificate of increased repair reserve fund are required. Condominiums that have received advice and guidance from the city need a certificate of implementation of the advice and guidance content. Additional documents may be requested. |
| Points to Note | Obtaining management plan certification and reviewing the long-term repair plan takes time, so it is recommended to prepare at least one year before the work. It is stated that the reduction of fixed asset tax for seismic, barrier-free, and energy-saving renovations cannot be used in the same fiscal year. The treatment after April 2027 cannot be confirmed on the official page. |

③ Management Plan Certification System (Entrance to Tax and Interest Rate Benefits)
Receiving certification leads to interest rate benefits for loans and bonds from the Housing Finance Agency, and fulfills one of the requirements for the longevity promotion tax system (certification alone does not guarantee tax reduction). Condominiums in Machida City have Machida City as the certification window, which started in January 2023 (Reiwa 5) along with the Machida City Condominium Management Improvement Promotion Plan. The certification criteria are the same as the national condominium management improvement guidelines, and there are no unique standards from Machida City. The main criteria include holding meetings at least once a year, maintaining management regulations, separate accounting for management fees and repair reserve funds, and “having a long-term repair plan that includes large-scale repair work at least twice and is created or reviewed within 7 years, with a planning period of 30 years or more”.
| Application Process | ① Request a preliminary confirmation from the Public Interest Incorporated Foundation Condominium Management Center, and if the criteria are met, a preliminary confirmation compliance certificate will be issued → ② Apply to Machida City through the Condominium Management Center’s “Management Plan Certification Procedure Support System” → ③ Pay the application fee according to the payment notice sent from the city → ④ The city will review and send a certification notification → ⑤ If agreed upon at the time of application, the certification information will be published on the Condominium Management Center’s website, in that order. |
|---|---|
| Fees | The basic fee is 4,100 yen, and if there are multiple long-term repair plans, an additional 1,800 yen will be charged for each plan, minus one from the total number of plans. Please check the costs on the Condominium Management Center’s guidance for any preliminary confirmation fees. |
| Number of Certifications | The city’s page does not list the number of certifications (the page was last updated on May 9, 2023). |

④ National Energy Conservation Support | Housing Energy Conservation 2026 Campaign
Changes for 2026The “Child-Rearing Green Housing Support Project” for 2025 has been abolished and reorganized into the successor “Mirai Eco Housing 2026 Project.” Additionally, the “Long-Term Excellent Housing Renovation Promotion Project” will end in Reiwa 7, and will not be implemented in Reiwa 8. Please be careful not to base your financial plans on outdated information.
Mirai Eco Housing 2026 Project
| Eligible | Renovations of existing homes built before December 31, 2016, regardless of whether they are single-family or multi-family residences. Management associations and management corporations can also become joint contractors (i.e., can be used for renovations of common areas). Rental housing is also eligible. |
|---|---|
| Required Work | Combination of insulation renovations for openings, structural (floor, wall, ceiling) insulation renovations, and installation of eco-friendly housing equipment is mandatory. |
| Subsidy Limit | Depending on the age of the building and the energy-saving performance achieved, 400,000 to 1,000,000 yen per unit (1,000,000 yen for homes built before 1991 that meet mandatory standards). |
| Period | Eligible projects must have construction contracts signed and construction must start between November 28, 2025, and no later than December 31, 2026. Grant applications are generally submitted by registered contractors (construction companies) after project completion (the client cannot apply themselves). Reservations for grant applications must be made by November 16, 2026, and grant applications must be submitted by December 31, 2026, at the latest (will end once the budget limit is reached). |
Advanced Window Renovation 2026 Project
| Target | Installation of inner windows, replacement of outer windows, glass replacement, etc., in existing homes (detached and multi-family) for upgrading to high-performance windows. In multi-family housing, subsidy rates are set separately for “low-rise” and “mid to high-rise” buildings. |
|---|---|
| Bulk Application for Multi-Family Housing | In multi-family housing, there is a method called “bulk application” where all units can be applied for together. The application process is carried out by registered contractors (window renovation contractors), and the management association cannot apply on its own, but this system works well with window and entrance door renovations that coincide with large-scale repairs. |
| Subsidy Limit | For residential properties, the limit is 1 million yen per unit (changed from 2 million yen for the fiscal year 2025). For non-residential properties over 240㎡, the limit is 10 million yen per building. |
| Period | Works that start on or after November 28, 2025, and by no later than December 31, 2026, are eligible. The application for the grant must be made after the completion and handover of the work, with reservations to be made by no later than November 16, 2026, and the grant application to be submitted by no later than December 31, 2026 (the program will end once the budget limit is reached). |
⑤ Subsidies and Grants in Tokyo and Information on Grants in Machida City

Tokyo Condominium Improvement Work Subsidy (Interest Subsidy)
| Content | This is a system where the Tokyo Metropolitan Government subsidizes the interest on the “Condominium Common Area Renovation Loan” from the Japan Housing Finance Agency. The subsidy covers the difference from the interest rate, which is 1% lower than the agency’s rate (if the interest rate is below 1%, it effectively becomes 0%), and the subsidy period is up to 20 years, which is the repayment period of the loan. |
|---|---|
| Eligibility | This applies to management associations of fire-resistant condominium buildings in Tokyo that utilize the agency’s loans and debt guarantees from entities such as the Condominium Management Center. Repairs and renovations of common areas are eligible (installation work for solar power generation equipment may also be eligible for loans; please confirm the conditions with the Japan Housing Finance Agency). For condominiums built before the earthquake resistance standards (before May 31, 1981), conducting an earthquake resistance diagnosis is a requirement, and for condominiums that require reporting on management status, it is a condition that the report and updates have been completed. |
| Limit | The limit is the smallest amount among the loan reservation amount, the construction cost eligible for the loan, the amount after deducting subsidies from the construction cost, and 2 million yen per unit (6 million yen if it involves earthquake reinforcement) multiplied by the number of units. |
| Application for Reiwa Year 8 | Applications are accepted in two phases, with the first phase (from May 13 to September 30) having ended. The second phase will be accepted from October 1, 2026, to February 19, 2027. There are 2,500 units available for each phase, on a first-come, first-served basis. After loan approval, applications and grant decisions must be received before the monetary loan agreement.

Cases Where Fire Insurance Can Be Used and Cases Where It Should Not Be Used
Damage caused by “accidental incidents” such as flying waterproof sheets, caps, and fences due to typhoons or strong winds, hail damage, and lightning strikes may be covered by fire insurance. It is important to separate and record damage caused by accidents from normal wear and tear during deterioration diagnosis.
On the other hand, normal wear and tear itself is not covered. There have been many troubles nationwide with contractors soliciting, “You can repair without any out-of-pocket costs with insurance,” and the National Consumer Affairs Center has repeatedly issued warnings. False claims can lead to insurance fraud charges. Please confirm the eligibility of claims directly with your management association or property owner with the insurance company or agent. Kakeru Koumuten Co., Ltd. does not provide such guidance.
Building Conditions and Repair Points in Machida City, Tokyo
Machida City has an area of 71.55㎢ and is shaped like a peninsula extending towards Kanagawa Prefecture at the southern tip of Tokyo. According to city documents, it spreads from the western to central part of the Tama Hills, with the lowest point at an elevation of 25m and the highest point at an elevation of 361.6m, indicating a significant elevation difference. The city’s basic survey (as of January 1, 2017) shows that there are 521 buildings and 23,729 units of condominiums, along with large-scale housing complexes from UR and JKK. The figures below are only those verified from official documents.

Source: Machida City “Basic Resident Register Households and Population 2026 September” (PDF)/Machida City “Location and Topography (Area)”/Machida City “Condominium Basic Survey Results” (June 2018, PDF) ※Population and number of households are based on the Basic Resident Register. The number of condominium buildings and units is based on the city’s survey as of January 1, 2017, which includes both private and public supply (UR and JKK).
As of 2017, about 90% of the condominiums in Machida City were less than 30 years old
According to the city’s basic survey, among the 349 buildings of privately supplied condominiums, approximately 86% (about 90% by unit count) were less than 30 years old. There were 49 buildings that were 31 years or older (completed before 1986), with 21 buildings and 495 units built under the old seismic standards (before May 1981). Nine years have passed since the survey, and the ages of the buildings have increased by nine years each. The table below replaces the classifications at the time of the survey with estimates of the building ages as of 2026.
| Year Built | City’s Actual Basic Survey (as of January 1, 2017) | Estimated Age (as of 2026) | Major Repairs in Next Renovation |
|---|---|---|---|
| Before May 1981 (Showa 56) This is an old seismic building |
Private supply: 21 buildings, 495 units (about 6% of the total number of buildings) | Over 45 years old | After the 3rd repair. Replacement of water supply and drainage pipes, replacement of iron parts and handrails, seismic diagnosis will be the main issues |
| June 1981 – 1986 (Showa 61) | Private supply: 28 buildings (number of buildings over 31 years old minus 21 old seismic buildings) | 40 to 45 years old | Around the 3rd repair. Measures for tile lifting and peeling, renovation of sashes and entrance doors will become more significant |
| After 1987 (Showa 62) | About 86% (by number of buildings) and about 90% (by number of units) of private supply | 39 years old or younger | From the 1st to the 3rd repair. Re-sealing and exterior wall painting, renovation of rooftop waterproofing will be the focus, and the planning of scaffolding and temporary structures will affect costs |
| Public Supply (UR/JKK) Sales | 6 locations, 172 buildings, 3,990 units. About 78% of the units (about 72% of the buildings) are over 40 years old | Many buildings are over 49 years old | After the 3rd repair. Review of long-term repair plans, replacement of water supply and drainage pipes and equipment will be the main issues |

Four Factors Influencing Buildings and Construction in Machida City
Based on public documents, we have organized four characteristics that are linked to large-scale repairs. Machida City has significant elevation differences in the Tama Hills, and due to the small scale of landscape notifications, it is essential to confirm scaffolding plans and notifications before starting construction based on the location.
① Climate | Temperature Differences, Heat Waves, Heavy Rain
According to the Japan Meteorological Agency’s observations in Tokyo (not from Machida City), the highest annual temperatures from 2021 to 2025 (the highest daily temperature of that year) ranged from 36.8 to 38.5℃, while the lowest annual temperatures (the lowest daily temperature of that year) ranged from -3.5 to -1.0℃ (the highest in 2025 was 38.5℃ in August). The annual precipitation varied significantly, with the highest in 2021 at 2,052.5mm and the lowest in 2025 at 1,152.5mm. Due to high summer temperatures and cold winters, the exterior walls, sealing, and waterproof layers undergo repeated expansion and contraction every year.We recommend inspecting the waterproof layers, sealing, and drains before any issues arise.
② Topography and Flooding | Tama Hills, Sakai River, Tsurumi River, Landslide Hazards
According to city documents, Machida City occupies the western to central area of the Tama Hills, with the highest point at an elevation of 361.6m (Daichizawa Ridge, Kusato Mountain) and the lowest point at an elevation of 25m (east side of Miwa Housing Complex). The elevation of the city hall is 81.1m. According to city documents (Machida City Flood and Landslide Hazard Map, March 2024), areas expected to flood with a depth of 0.5m or more account for 8.5% of the city (606.3ha), affecting 14,821 buildings (11.8%), with the majority of these areas along the Sakai River and Tsurumi River. Internal flooding occurs sporadically in urban areas, particularly in valley-shaped locations. The flood risk from rainwater runoff assumes rainfall of 153mm per hour. The landslide hazard areas cover 5.8% of the city (417.4ha), affecting 5,232 buildings (4.2%), with 1,510 buildings (1.2%) in special warning areas. Most of these are due to collapses in steep areas, scattered throughout the northern hilly regions, and designated in urban development areas. Please check the city’s hazard maps and Tokyo’s landslide hazard area maps to see which assumptions apply to your property.
③ Types of Buildings | Condominiums and Large-Scale UR/JKK Housing Complexes
According to the city’s basic survey (as of January 1, 2017), there are 521 condominium buildings with 23,729 units, with private supply accounting for 349 buildings (19,739 units) and public supply (UR/JKK) for 172 buildings (3,990 units) across six locations. The 2013 Housing and Land Statistics Survey indicated that apartment buildings made up about 51% (104,780 units) of the 205,950 residential units, with approximately 76% of these being rental units. According to the city’s page, the Kiso Yamazaki Housing Complex Area (with 4,736 units in Machida Kiso Housing, 4,225 units in Yamazaki Housing Complex, 904 units in Kiso Housing, and 260 units in Yamazaki Second Housing Complex) totals 10,125 units, with occupancy starting from the Showa era 38 to 44. The Tsurukawa Housing Complex has 2,938 units (Showa 42), and the Koyamada Sakuradai Housing Complex has 1,618 units (Showa 58). In complexes with many buildings, the order of scaffolding assembly for each building and the use of pathways and parking lots can significantly affect construction periods and resident interactions.
④ City Rules | Landscape Planning Notifications and Guided Areas
Machida City is entirely designated as a landscape planning area, divided into three zones: “Hilly Zone,” “Residential Coexistence Zone,” and “Vibrancy Zone.” The landscape formation guided areas include Onoji-juku Street, Machida Station Front Street, and Tamaki Sakaido Street. A notification is required for buildings that are 10m or taller, have 9 or more units in a multi-family dwelling, or have a total floor area of 1,000㎡ or more (the Onoji-juku Street landscape formation guided area requires a total floor area exceeding 10㎡). Actions requiring notification include “repairs or renovations that change the exterior or color.” According to the city’s Q&A, even repainting in the same color requires notification, and repainting in the existing non-compliant colors is not permitted. Notifications must be submitted 30 days prior to construction start if a building confirmation application is required, or 30 days prior to construction start if not required. Construction actions with a total floor area of 3,000㎡ or more or multi-family dwellings with more than 50 units also require prior consultation. The contact point is the District Urban Development Division, Urban Development Landscape Section (042-724-4267). The number of district plans, building agreements, and greening rules could not be confirmed from the city’s page. Please check with the contact point for each property.

Key Points to Consider When Proceeding with Construction in Machida City
| Issue | Current Situation in Machida City and Kakeru Koumuten’s Response |
|---|---|
| Road Occupation and Delivery | If scaffolding or temporary enclosures extend onto the road, a road occupation permit is required. For municipal roads, the contact is the Road Management Division, Machida City (042-724-1149), while for metropolitan and national roads, it is the respective road administrators. According to the city’s page, the occupation fee for scaffolding and temporary enclosures is 11,500 JPY per square meter per year (prorated for less than one year), and an extension of the morning glory requires a new occupation permit application. The number of days until permission is not specified on the city page, and the road usage permit is a procedure with the jurisdictional police station. We will confirm the front road and delivery route on-site, incorporating the need for occupation and the number of days into the project schedule. |
| Landscape Plan Notification | A notification is required if the height is 10m or more, if there are 9 or more units in a collective housing, or if the total floor area is 1,000㎡ or more, and even repainting in the same color is subject to this. We will confirm whether it is subject to notification and the timing of the notification (30 days prior) before starting construction. |
| Elevation Differences in Hilly Areas and Delivery Routes | The elevation in the city ranges from 25m to 361.6m, with 5,232 buildings (4.2%) located in sediment disaster warning areas. We will check the delivery vehicle route through slopes, the location for material storage, and the condition of the ground and slope for scaffolding before planning the scaffolding. |
| Large-Scale Repairs in Housing Complexes | In large-scale complexes of UR and JKK, or in sites with many buildings, we will organize the diagnostic results for each building, incorporate the order of scaffolding assembly, material storage, usage of pathways and parking lots, and the communication system with residents into the project schedule. |
| Age Layers and Scale of Units | As of 2017, about 61% of private supply consisted of 40 units or fewer. We will categorize the diagnostic results into “must fix this time,” “consolidate while scaffolding is up,” and “can wait until next time,” considering the heavier burden per unit for fewer units, and propose multiple plans. |
| Drainage Around Riverbanks and Valleys | There are predicted flood areas along the Sakai River, Tsurumi River, and Onda River, and urban areas with internal water flooding are scattered in valley-shaped locations. We will organize issues such as blockages in roof drains, gutters, and drainage pipes, as well as how water enters around low floors and basements during the diagnosis. |

*We accept consultations throughout Machida City.
Deterioration Symptoms and Timing Requiring Major Repairs
Generally, major repairs are considered to be on a 12 to 15-year cycle. According to the Ministry of Land, Infrastructure, Transport and Tourism’s actual survey, the actual repair cycle is most commonly 13 years, with about 70% falling within the 12 to 15-year range, and the cycle tends to shorten with each occurrence. However, the actual determination should be based on the deterioration condition rather than the number of years, so if you observe symptoms like those listed below, we recommend an early on-site inspection.
| Location | Dangerous Signs of Deterioration if Left Untreated | Main Actions |
|---|---|---|
| Exterior Wall (Painted Surface) | Chalking (white powder on hands), fading, cracks wider than 0.3mm, blistering or peeling of paint | Substrate repair + exterior wall painting |
| Exterior Wall (Tile Surface) | Tile lifting or falling off, chipping of joints, efflorescence, hollow sound when tapped | Injection for lifting, replacement, clear waterproofing |
| Sealing | Cracks in joints, shrinkage, peeling, hardening | Re-sealing |
| Roof and Balcony | Bloating or breaking of waterproof layer, puddles, clogged drains, rain leaks to lower floors | Urethane waterproofing, sheet waterproofing, drain renovation |
| Metal Parts and Steel Stairs | Rust, peeling paint, corrosion of treads | Grinding + rust prevention + painting, component replacement |
| Roof | Lifting of ridge cap, cracking or warping of slate, moss, shifting of tiles | Roof painting, roof overlay (cover method), re-roofing |
| Concrete | Spalling (exposed rebar with rust stains), water leakage from cracks | Spalling repair + resin mortar filling |
| Shared Hallways and Stair Floors | Lifting, peeling, or opening of edges of long sheets, exposure of substrate | Replacement of long sheets + substrate waterproofing |
Repair Cycle Guidelines by Location (Ministry of Land, Infrastructure, Transport and Tourism)
| Location/Work | Estimated Cycle | Location/Work | Estimated Cycle |
|---|---|---|---|
| Exterior Wall Painting (Repainting) | 12-15 years | Re-sealing | 12-15 years |
| Exterior Wall Painting (Existing Removal + Painting) | 24-30 years | Metal Part Painting | 5-7 years |
| Roof Waterproofing (Repair) | 12-15 years | Water Supply Pipe (Rehabilitation/Replacement) | 19-23 years / 30-40 years |
| Roof Waterproofing (Removal/New Installation) | 24-30 years | Drain Pipe (Rehabilitation/Replacement) | 19-23 years / 30-40 years |
*The above are reference examples from the guidelines and are not uniform construction deadlines. Actual cycles will be set according to the building’s specifications, location conditions, and deterioration status.

Examples of Large-Scale Renovation Work
This is an example of exterior renovation work on a mixed-use building undertaken by Kakeru Koumuten. The building had leaks occurring in several places, and we combined clear waterproofing for the tile exterior wall with waterproofing for the roof for the renovation.
Exterior Renovation Work for Mixed-Use Building (Tile Wall Waterproofing + Roof Waterproofing)
| Work Details | Partial tile replacement / Painting of ancillary parts (pipes, water drainage) / Roof waterproofing work (urethane waterproofing) / Wall tile waterproofing (Seven S) / Sealing work around windows / Repair of wall tile mortar joints / Removal of ivy |
|---|---|
| New Materials Used | Wall tiles: Kunishiro Tiles / Ancillary part painting: Radical silicone paint / Roof waterproofing: High-strength urethane (Sarasene A) / Wall tile waterproofing: Seven S |
| Price Range | 4,000,000 to 4,100,000 JPY |
| Construction Period | 45 days |
| Location | Not disclosed |
| Background to the Construction | Due to leaks occurring from several locations, including the exterior walls and roof, we proposed waterproofing for the entire exterior wall. Seven S is a clear waterproofing material for tile walls, and while the cost is somewhat higher, it is highly waterproof, making it recommended for cases where leaks are occurring from multiple areas of the exterior wall. |
Customer Feedback
Flow from On-Site Investigation to Completion of Construction
From the initial inquiry to the completion of the work and aftercare, a single representative will consistently handle your case. For management associations, a resolution at the general meeting is required, so it is advisable to start the process 1 to 1.5 years before the desired start date to allow for a smooth progression.
- Inquiry (Free) Please contact us via phone, form, or LINE. If you have estimates from other companies, just presenting those is fine.
- On-site Investigation & Building Diagnosis (Free) We will conduct a survey of the exterior walls, check for cracks, sealing, and waterproof layers, and if necessary, investigate the rooftop, high places, and leak areas using drones or thermal imaging. For properties in Machida City, we will also check the site conditions, trees, elevation differences in hilly areas, road widths, the necessity of road occupation, distances to neighboring buildings, potential flooding or landslide risks from the Sakai River and Tsurumi River, as well as delivery routes and parking.
- Submission of Investigation Report & Estimate We will provide a deterioration diagnosis report with photos and an estimate detailing quantities, methods, and materials for each work item. Multiple plan proposals are also possible.
- Plan Decision & Contract Confirm colors through color simulations, paint samples, and trial painting. For management associations, we will assist in preparing materials for the general meeting. If a notification for the Machida City landscape plan is required, we will also explain the color considerations.
- Notification to Residents & Neighbors We will distribute construction notifications, visit neighbors to greet them, and set up a bulletin board at the entrance (with a schedule and laundry information). If temporary relocation of parking is necessary, adjustments will be made at this stage.
- Installation of Temporary Scaffolding & Various Works Our in-house scaffolding team will set up the scaffolding, followed by high-pressure washing → substrate repair → sealing → exterior wall painting & tile repair → waterproofing → iron parts & ancillary works in that order. A responsible person will inspect and take construction photos at each stage.
- Completion Inspection, Scaffolding Dismantling & Handover We will confirm the finish in the presence of the customer and provide construction photos, a report on the paint used, and the warranty.
- Aftercare We will send out annual DM notifications and inspections are possible every year. Simple repairs such as partial sealing are provided free of charge.
Resident Communication, Approval for Additional Work, Inspection Reports
Equally important as the construction itself is “when, what, and with what materials we report”. At Kakeru Koumuten, we will provide materials and reports in the following four situations.
| Situation | Materials Provided / Actions Taken |
|---|---|
| Before Construction Building Diagnosis |
We will provide a deterioration diagnosis report with photos. This document summarizes the deteriorated areas and the basis for the proposed scope of work. |
| Before Construction to During Construction Notification to Residents & Neighbors |
We will distribute construction notifications, visit neighbors to greet them, and provide information on the schedule and laundry through the entrance bulletin board. |
| During Construction Approval for Additional Work |
Deterioration discovered after scaffolding is set up will be addressed by presenting photos, quantities, and costs for approval before proceeding with the work. |
| During Construction to Completion Inspection Report |
A responsible person will inspect each stage and take construction photos. At completion, we will confirm the finish in the presence of the customer and provide construction photos, a report on the paint used, and the warranty. |
* For management associations, it is smooth to decide in advance who will approve additional work (such as the chairman or the repair committee) and the approximate amount that will require approval before signing the contract.
How will life be during construction? Impact on residents
Large-scale repairs are principally carried out while residents remain in their homes. However, there will be restrictions on daily life while scaffolding is in place. Most troubles can be prevented simply by providing advance notice, so Kakeru Koumuten Co., Ltd. thoroughly explains and posts information before construction begins.
| What will be affected | What will actually happen / Our response |
|---|---|
| Laundry | On days of high-pressure washing, painting, and waterproofing, outdoor drying will not be possible. We will inform you via bulletin board and each unit’s mailbox about “which side will be worked on today” and will secure as many days as possible for drying. |
| Window opening and closing | In addition to washing and painting days, there may be times when windows cannot be opened during processes such as protection, drying, and waterproofing. We will provide information for each process, so please check the postings and notifications. We will schedule the work to avoid continuous closures. |
| Balcony | During floor waterproofing and handrail painting, we ask for temporary relocation of personal items, plants, and air conditioning outdoor units. The timing will be notified in advance for each unit. |
| Noise and odor | The period of substrate repair (breaking and drilling) will be the noisiest. Working hours are generally from 8 AM to 5 PM, and we will accommodate requests such as refraining from work on Sundays and holidays. Low-odor paint options are also available. |
| Security and privacy | Scaffolding can become an entry point. We can take measures such as blocking sightlines with mesh sheets and installing locks and sensor lights on the scaffolding’s access stairs at night. We also thoroughly educate visitors on proper etiquette. |
| Parking | Vehicles on the side where scaffolding will be erected will need to be temporarily relocated. Since securing a new parking spot may take time, we will work together to secure a relocation spot starting 2 to 3 months before construction begins. |
| Pets, small children, and working from home | If you have sensitivities to noise, please inform us in advance, and we may be able to adjust the work schedule accordingly. Please feel free to let us know. |
| Rented rooms | We can assist owners in creating notification documents for residents. If there are concerns about the impact of construction on occupancy rates, we can also propose a color simulation for an image change. |
How to choose a large-scale repair contractor and ordering method
There are many large-scale repair contractors that cover Machida City, Tokyo, and you may be unsure which one to choose. When requesting renovations for apartments, condominiums, or buildings, please confirm the following four points.
● Have extensive experience in large-scale repairs
● Confirm the presence of warranties and aftercare services
● Obtain estimates from multiple contractors (at least 3 companies)
● Confirm whether they manage their own work
Have extensive experience in large-scale repairs
Large-scale repair contractors often have websites that showcase their exterior renovation achievements. If they provide detailed explanations of repair contents with photos, it gives peace of mind as it can serve as a reference when actually requesting work.
Using ratings from Google and review sites can be effective when comparing large-scale renovation contractors!Be cautious if there are many negative reviews. If there are few reviews, also check the construction track record, the content of explanations, and the management system.
Large-scale renovation work involves not only the construction itself but also the potential for troubles with residents and neighboring residents, so it is necessary to report the progress of the work and information about laundry on bulletin boards to prevent issues before they arise. Kakeru Koumuten Co., Ltd. specializes in exterior work, and we receive many requests for exterior renovations of apartments and condominiums.
Check for warranties and aftercare services
When choosing a large-scale renovation company, check for the presence of warranties. If any issues such as leaks occur after construction, having a leak warranty from the contractor means repairs can be made at no cost, providing peace of mind! Companies that offer warranty periods can be seen as having confidence in their work, which can serve as a criterion for choosing a contractor.
Warranty periods vary by contractor and the nature of the work, but a range of 1 to 10 years is common. Emergency repairs or partial repairs often do not come with a leak warranty. Some contractors also offer aftercare services separate from warranties, so be sure to check for warranties and aftercare services.
At Kakeru Koumuten Co., Ltd., we send out annual direct mail for aftercare maintenance, allowing for yearly inspections. We also provide free responses for simple repairs such as partial sealing.
Obtain estimates from multiple contractors (at least 3 companies)
When requesting large-scale renovations, obtain estimates from multiple contractors. It is important to get estimates from at least 3 companies and compare the estimates and reports from each! Even for the same work, costs can vary between contractors, and warranties and aftercare services may differ. Additionally, obtaining multiple estimates makes price negotiations easier.
When comparing estimates, consider not only the cost but also the “items in the estimate,” “methods and materials for substrate repair and exterior wall painting,” and “confirmation of the process” to make a detailed judgment! If the quality of auxiliary materials is low or if processes are skipped, costs can be reduced, so avoid making decisions based solely on price. Especially since substrate repair work is often not visible from the outside, be sure to check whether the repair method is appropriate for the condition of the substrate!
Check these points on the estimate (checklist)
| Confirmation Items | Points to Consider |
|---|---|
| Is there an excessive use of “one set” notation? | Are the quantities and unit prices clearly stated? With “Exterior Wall Repair One Set,” comparisons and verifications cannot be made. |
| Do the quantities match the actual measurements? | Are there quantities recorded that are far from the drawings or actual measurements? This is the area where inflation is most likely to occur. |
| Proportion of miscellaneous expenses | Details and proportions of site management costs, general management costs, statutory welfare costs, etc. According to the Ministry of Land, Infrastructure, Transport and Tourism’s survey for the 3rd year of Reiwa, the average is about 10% of the construction cost (excluding common temporary costs), but it varies depending on the size and conditions of the building, so there is no uniform standard. |
| Are the names of materials written? | Are the manufacturer names, product names, grades, and number of coats for paints and waterproofing materials listed? |
| Treatment of quantities for substrate repairs | This is an item that cannot be accurately measured until scaffolding is set up. Is it stated whether it is “estimated quantity” or “actual quantity settlement,” and are there agreements for increases or decreases? This is the most important point. |
| Guarantee and after-inspection | Warranty period for each construction, frequency of inspections, and scope of free support. |
| Company backing | Type of construction industry license, track record of similar scale and structure, presence of qualified personnel. |
Confirm if it is managed in-house
Large-scale repair work includes various tasks such as “substrate repair work,” “exterior wall painting,” “waterproofing work,” and “pipe replacement,” and the plan content will change depending on the actual deterioration condition and the customer’s wishes.
Contractors that completely outsource to subcontractors lack knowledge and experience, which may lead to proposals for repairs in irrelevant areas or unnecessary work. If you request a subcontractor after investigation, it may incur additional time and costs. By having knowledge and experience and managing in-house, responsible construction can be carried out at a reduced cost.
Moreover, contractors that outsource to subcontractors may also have delayed responses in case of any troubles during construction. It is safer to avoid companies that do not actually meet with customers to manage the construction. Kakeru Koumuten performs everything from temporary scaffolding setup to exterior wall painting and waterproofing work in-house, managed by knowledgeable and experienced personnel!
There are three ordering methods. The choice affects the approach.
Especially for management associations, it is necessary to decide “how to request” before “which company to ask.” The main ordering methods are the following three.
| Method | Procedure | Advantages | Disadvantages |
|---|---|---|---|
| Responsible Construction Method | The construction company handles investigation, design, construction, and management all at once | No additional costs for commissioning design consultants (investigation and design costs may be included in the construction costs) / A single point of contact reduces the burden on the management association / Responsibility is clear / The period until ordering can sometimes be shortened | Specifications can easily be left to the construction company, making it difficult to compare side by side / Third-party checks are hard to implement, requiring the management association to verify price, specifications, and construction status |
| Design Supervision Method | A design office or consultant conducts investigation and design, while a separate company handles construction | Allows for comparison of construction companies under the same conditions / Independent supervision during construction | Consulting fees are required separately / Attention is needed for risks of conflicts of interest and collusion / The period can easily become prolonged |
| Management Company Prime Contract Method | The management company acts as the prime contractor, with subcontractors performing the construction | Easy coordination with daily management / Minimal burden on the management association | Intermediate margins can make it more expensive / Competition principles may not be effective |
Collusion and Inappropriate Consulting Issues in Large-Scale Renovations and Self-Defense Measures
Latest 2026 In the large-scale renovation industry, inappropriate orders linked between design consultants and construction companies have long been a problem. The Ministry of Land, Infrastructure, Transport and Tourism issued warnings and notifications to management associations in January 2017 and April 2023, and on September 28, 2026, the Japan Fair Trade Commission announced that it had issued exclusion orders to 38 companies and payment orders for a total of 1.63788 billion yen to 37 companies regarding large-scale renovation work commissioned by condominium management associations in the Kanto region to design consulting firms (two design consulting firms were also subject to exclusion orders).
※Based on the announcement by the Japan Fair Trade Commission (September 28, 2026).
Three Typical Methods
① Dummy Estimates
Prior to placing an order, companies decide on a contractor, while other companies only provide high estimates in a formal manner, creating a “fixed race.” This gives the impression to the management association that they have properly obtained competitive estimates.
② Collusion with Design Supervisors
Consultants contract at extremely low design supervision fees while receiving kickbacks from the high construction costs of partnered contractors. Beware of design supervision fees that are too low as they are a warning sign.
③ Back Margin
A certain percentage of the contract amount is given as a kickback, which is then added to the construction costs as an expense. As a result, the management association ends up paying extra.
Self-Defense Measures for Management Associations
- Obtain independent estimates from multiple companies
- Consult neutral third parties such as condominium management professionals or architects
- Document the contractor selection process in meeting minutes to ensure transparency
- Confirm the reasons for unusually low consulting fees
- Include a penalty clause in the contract for cases of collusion
- Avoid concentrating information with a single consultant and verify specifications independently
Frequently Asked Questions about Large-Scale Renovations in Machida City, Tokyo
- How much does a large-scale renovation in Machida City, Tokyo cost?
- For condominiums, according to the Ministry of Land, Infrastructure, Transport and Tourism’s survey for the fiscal year 2021, about 70% of cases fall within the range of 750,000 to 1,500,000 yen (excluding consumption tax and common temporary construction costs), with the most common range being 1,000,000 to 1,250,000 yen. Based on our company’s construction records, the estimated costs are 2,000,000 to 4,000,000 yen for wooden two-story apartments, 4,000,000 to 9,000,000 yen for three-story steel and RC apartments, and 5,000,000 to 15,000,000 yen for small-scale condominiums and mixed-use buildings. Costs may vary depending on the condition of the substrate and whether waterproofing and roofing work are needed, so we provide free on-site estimates.
- How often should large-scale renovations be conducted?
- Generally, a cycle of 12 to 15 years is recommended, and the actual cycle is most commonly 13 years according to the Ministry of Land, Infrastructure, Transport and Tourism’s survey, with about 70% falling within the 12 to 15-year range. However, the determining factor should be the condition of the building rather than just the number of years. If there are signs of deterioration such as sealing degradation, tile lifting, or breaks in the waterproof layer, it is advisable to carry out repairs without waiting for the cycle, as this can ultimately reduce costs. As of January 1, 2017, there were 521 buildings and 23,729 units of condominiums in Machida City, with about 86% of the privately supplied units being less than 30 years old at that time. Given that nine years have passed since the survey, it is believed that more buildings are now reaching the timing for their first or second large-scale renovations. There are 21 buildings that fall under the old seismic standards (built before 1981).
- How long does the construction period take? Can residents stay during the work?
- The estimated construction period is about 3 weeks to 2 months for apartments, 1.5 to 3 months for small-scale condominiums and buildings, and about 4 to 6 months for condominiums with more than 50 units. Residents can remain in their homes during the construction. However, while scaffolding is in place, there may be restrictions on drying laundry outside and opening windows, so we take thorough measures to minimize the impact on daily life, including distributing advance notices, providing information on the bulletin board about the construction schedule and laundry, and strictly adhering to working hours.
- How long should I expect from the start of planning to the completion of construction?
- For management associations, it typically takes about 1 to 1.5 years for the establishment of the repair committee, building diagnosis, contractor selection, and general meeting resolutions, followed by 3 to 6 months for construction. Overall, it is advisable to plan for about two years to proceed comfortably. If you are using subsidies or tax incentives, please factor in the time required to obtain management plan certification (resolutions at the general meeting, pre-confirmation, and certification application).
- Are there any subsidies available for large-scale renovations in Machida City, Tokyo?
- As of the latest information available on the official Machida City website, there do not appear to be any municipal programs that subsidize the construction costs or deterioration diagnosis costs for large-scale renovations of condominiums (as of October 14, 2026. Please confirm with the city’s housing department for the final details). The city’s support includes subsidies for promoting seismic retrofitting and consultation services and seminars related to condominium management. For large-scale renovations, if the condominium meets the requirements, you may consider the reduction of fixed property tax under the “Condominium Longevity Promotion Tax System” (in Machida City, this is a reduction of one-third of the city tax; urban planning tax is not reduced) or loans from the Japan Housing Finance Agency, as well as the Tokyo Metropolitan Government’s “Condominium Improvement Construction Subsidy” (interest subsidies; applications for the second phase of fiscal year 2026 are accepted until February 19, 2027). The management plan certification is handled by Machida City (Housing Department). Additionally, if the work includes windows and insulation, it may be eligible for national programs such as “Advanced Window Renovation 2026,” “Mirai Eco Housing 2026,” and the Tokyo Metropolitan Government’s energy-saving renovation promotion project for existing homes. The application timing and applicants vary by program, so please check the eligibility conditions and application procedures for each program before contracting and starting construction.
- I heard that fixed property taxes can be reduced with large-scale renovations. Is that true?
- If the requirements are met, a reduction will be applied. Under the condominium longevity promotion tax system, if a condominium that is over 20 years old and has more than 10 units conducts large-scale repairs (such as exterior wall painting, floor waterproofing, and roof waterproofing as a single project) that contribute to its longevity, the fixed asset tax for the building for the following year will be reduced by up to the equivalent of 100 square meters per unit. The reduction rate is determined by local ordinances, and in Machida City (the fixed asset tax is a city tax), it is one-third (the urban planning tax is not reduced). The eligible projects are those completed between April 1, 2023, and March 31, 2027, and the application should be submitted to the Machida City Asset Tax Division, Building and Depreciable Assets Section (042-724-2118), with a deadline of within three months after project completion. For certified management plan condominiums, there are additional requirements such as increasing the repair reserve fund, so it is recommended to start preparations more than a year in advance.
- Are there any changes to subsidies starting from the 2026 fiscal year?
- Yes. The national “Childcare Green Housing Support Project” has been abolished and reorganized into the successor “Mirai Eco Housing 2026 Project.” Management associations and management association corporations can also become joint project participants, allowing for insulation renovations in common areas. Additionally, the “Long-Term Excellent Housing Renovation Promotion Project” will end in the 2025 fiscal year and will not be implemented in the 2026 fiscal year. The “Advanced Window Renovation 2026 Project” has a method for collective applications for apartment buildings (the application process is handled by registered contractors). Please be careful not to base your financial planning on outdated information.
- What should I do if the repair reserve fund is insufficient?
- There are mainly four options. ① Postpone low-urgency repairs based on a deterioration diagnosis to the next time, ② Review the scope and specifications of the work, ③ Check for support systems such as subsidies, ④ Consider increasing the repair reserve fund or financing from the Japan Housing Finance Agency. The agency’s financing for renovations of common areas in condominiums does not require collateral, and interest rates can be reduced by up to 0.6% per year by obtaining management plan certification and implementing energy-saving and seismic work. Please note that postponing waterproofing and tile peeling measures often ends up being more expensive, so please consult us regarding the decision to separate these tasks.
- Can scaffolding be set up if there is a height difference on the site or if the front road is narrow?
- Yes, it can be set up. Most of Machida City is part of the Tama Hills, with elevations ranging from 25 to 361.6 meters, resulting in height differences. The focus of the scaffolding plan is on the slopes and height differences of the hilly terrain, the width of the front road, temporary plans for sites with many buildings, the distance to neighboring buildings, and whether a road occupancy permit is required. If scaffolding and temporary enclosures occupy the road, a road occupancy permit from the road administrator (for municipal roads, it is the Machida City Road Management Division, Permit Section) and a road use permit from the jurisdictional police station are required, with the occupancy fee set at 11,500 yen per square meter per year according to the city’s page. The number of days required for permission can be confirmed at the counter. The conditions of the site and the delivery route vary by building. Kakeru Koumuten Co., Ltd. owns its own scaffolding materials and has its own scaffolding team, allowing us to plan the layout, delivery route, and delivery time after checking the site. This is an area where additional costs can easily arise after seeing the site, so it is important to confirm the delivery route and whether occupancy is necessary during the estimation stage.
- What happens to the parking for residents during construction?
- Vehicles on the side where scaffolding will be erected will need to be temporarily moved. The number of parking spaces and availability varies by building, and securing a relocation spot may take time depending on the availability of nearby parking lots. Kakeru Koumuten Co., Ltd. will coordinate with you regarding the availability of nearby coin parking and monthly parking lots starting 2 to 3 months before construction begins.
- Can I freely decide the color of the exterior walls?
- In Machida City, a notification based on the Machida City Landscape Plan may be required. The scale criteria include buildings over 10 meters in height, apartment buildings with more than 9 units, and total floor areas of over 1,000 square meters, which vary by area. According to the city’s page, changing the color of the exterior is also subject to notification, and even repainting in the same color requires notification. Notifications must be submitted at least 30 days before the start of construction. The contact point is the Machida City Urban Development and Landscape Section (042-724-4267). Whether a notification is necessary depends on the location of the building and the scope of the work, so please check in advance. Our company will also investigate this during the survey. Sharing a color simulation to visualize the completed image can facilitate discussions at general meetings and with neighbors.
- Why is the north side of the exterior wall particularly covered in moss and algae?
- If you do not carry out large-scale repairs, various issues may arise. For example, water leaks can worsen, leading to structural damage and increased repair costs in the long run. Additionally, the aesthetic appeal of the building may decline, potentially affecting property value. Regular maintenance and timely repairs are essential to ensure the longevity and safety of your property. Ignoring these needs can result in more significant problems that could have been easily prevented. It is advisable to address any repairs promptly to avoid further complications.There are risks such as personal injury accidents caused by the peeling of exterior wall tiles, structural deterioration due to corrosion of rebar, water leaks, and a decrease in asset value. Furthermore, for buildings subject to regular reporting under Article 12 of the Building Standards Act, investigations through comprehensive probing are required under certain conditions, such as when more than 10 years have passed since completion or exterior wall renovations for tiles and mortar-finished walls. The contact point for regular reporting of buildings in Machida City is the Machida City Building Development Review Division, Building Guidance Section. Please check the conditions for the number of floors and floor area applicable to apartment buildings, as well as the submission destination for reports, in the list of buildings subject to regular reporting in Tokyo or at the city office. Complex buildings including stores, restaurants, hospitals, and hotels may also be subject to reporting depending on their usage and scale, so individual confirmation is necessary. Even if not subject to statutory investigations, regular inspections and maintenance are essential, so please consult us if you are unsure.
