[Kita-ku, Tokyo] Renovation of Vacant Houses and Used Properties | Costs, Subsidies, and Case Studies
For those considering renovations of used properties and vacant houses in Kita-ku
I bought a used property, but I’m unsure if the renovation estimate I received is reasonable.
This is my first full renovation, and I’m worried about making mistakes.
I want to make the most of subsidies and grants available.
For such concerns, Kakeru Koumuten Co., Ltd., which serves the Kita Ward area, will clearly explain the points to consider when planning a renovation.
Let’s compare contents with multiple estimates!
01Reasons for the Increase in Renovations of Used Properties and Vacant Houses in Kita Ward
Kita Ward in Tokyo is a town centered around Akabane, Oji, and Jujo, where wooden single-family homes and large-scale housing complexes are spread out. The mix of the Musashino plateau’s cliff lines and lowlands creates a coexistence of a downtown atmosphere and residential areas.
For wooden houses and aging apartment buildings, it is essential to reassess aspects such as seismic resistance, insulation, and plumbing according to the condition of the building. In Kita Ward, there is the option to “purchase used single-family homes or apartment buildings and renovate them to suit your lifestyle.”
Downtown Residential Areas of Akabane and Jujo
In areas like Akabane and Jujo, there are shopping streets and residential neighborhoods, where you can find aging wooden single-family homes. When purchasing, be sure to check the structure, deterioration status, and road access conditions.
Seismic Reinforcement in Densely Built Wooden Areas
There are areas densely populated with wooden structures where seismic reinforcement is crucial. The upper limit for seismic retrofitting in Kita Ward is raised in these developed areas.
Topography of Cliff Lines and Lowlands
The mix of cliff lines and lowlands at the edge of the Musashino plateau requires consideration for retaining walls, moisture, and drainage in certain locations.
High Aging of Large-Scale Housing Complexes
In aging housing complexes and apartment buildings, we check the boundaries of private and common areas, management regulations, and the condition of plumbing, insulation, and water facilities.
This article summarizes the reasons, points to consider, cost estimates, subsidies for 2026, and how to choose a contractor for those considering renovating used properties or vacant houses in Kita-ku, from the perspective of Kakeru Koumuten, which operates in the Kita-ku area.
One Important Check is “Comparative Estimates”
When considering renovations, it is advisable to obtain comparative estimates from multiple construction companies and compare them based on the scope of work, materials used, and warranty conditions. Kakeru Koumuten also accepts inquiries regarding renovations of vacant houses and used properties in Kita-ku.
02Reasons for Renovating Vacant Houses and Used Properties
In recent years, the Japanese housing market has expanded options not only for new constructions but also for renovating used properties. There is a growing interest in living in renovated or refurbished used homes. Here, we explain the typical reasons for renovating vacant houses and used properties.
Reason 1 To Live Comfortably as Your Own Home
A common reason for purchasing and renovating a used property is “to live comfortably.” Older homes often have issues with the roof, exterior walls, and water facilities, making them less livable as they are. By renovating and upgrading the equipment and interior, you can create a comfortable living environment. Additionally, with changes to the layout and refreshing the interior, depending on the condition of the building and the scope of work, you can achieve a home that suits your family’s lifestyle while keeping costs lower than new construction.
Reason 2 To Increase Asset Value for Sale
There are cases where a used property is purchased and renovated for the purpose of resale. The deterioration and age of equipment in used homes can impact their valuation, but by renovating to improve appearance and performance, there is a possibility of enhancing the property’s value.
Reason 3 To Utilize as an Investment or Business
When utilizing used properties for investment or business purposes, renovations may be necessary. By preparing them as rental housing or share houses, you can differentiate them from other properties, but profitability varies based on location, demand, renovation costs, and maintenance expenses. Many subsidies and tax incentives are limited to owner-occupied use, so be sure to check the intended use and eligibility conditions in advance.
03Points to Consider When Renovating Vacant Houses and Used Properties
Point 1 Choose a Reliable Construction Company
First and foremost, it is essential to select a contractor you can trust to handle your renovation with peace of mind. For used properties, since there were previous occupants, the internal structure and condition are often not clear until you actually see them. Choose a contractor that can carry out the work thoroughly according to your wishes, the structure of the house, and the surrounding environment, and also provides aftercare following the construction.
Point 2 Always Check the Deterioration of the Building
For used properties and vacant houses, it is crucial to check which parts are deteriorating and to what extent beforehand. Since there have been other occupants, the internal damage is often not known without investigation. Be sure to understand any hidden deterioration through a current condition survey before starting construction.
Point 3 Review Earthquake Resistance and Insulation Performance
Particularly important in the renovation of used and vacant houses is the review of earthquake resistance and insulation. The earthquake resistance standards were significantly revised in 1981, and houses built before that may not meet current standards. Furthermore, in 2000, regulations regarding joints and foundations were strengthened, making older buildings more likely to lack earthquake resistance. Check the condition of the building before starting construction, and be sure to check earthquake resistance and insulation.
Point 4 Check Subsidy Programs and Renovation Tax Deductions
To reduce construction costs, it is important to check for subsidies and renovation tax deductions. Subsidies are provided by the national and local governments, supporting part of the costs for earthquake retrofitting, energy-saving construction, and barrier-free renovations. Tax deductions include “housing loan tax deductions” when using a housing loan, and there are systems where part of the costs can be deducted for certain works even with personal funds. These can sometimes be used in combination, so checking in advance and planning to utilize them strategically is key to a successful renovation (for the latest information, see this subsidy section).
04 Cost Estimates for Renovating Vacant Houses and Used Properties

For the finishing material, we used the lightweight and durable natural stone granule-coated steel roofing material, Diplomat Star. Please note that if the underlying structure is severely damaged, the overlay method may not be applicable, and we will determine the appropriate method after an on-site inspection.
07How to Choose a Renovation Contractor for Used Properties and Vacant Houses in Kitaku
There are many renovation companies that serve Kitaku, and it can be confusing to decide which one to choose. When requesting renovations, be sure to check the following five points.
- Experience in renovation work
- Check for warranties and after-sales maintenance
- Obtain estimates from multiple contractors
- Confirm whether they perform renovations in-house
- Check if they offer color simulations and perspective drawings
1. Experience in Renovation Work
Many renovation contractors publish their work achievements on their websites. If a contractor provides detailed explanations of the process with photos, it can help you visualize the outcome after your request, giving you peace of mind. If you’re uncertain, choose a contractor with ample experience.
Google and review sites can also be helpful. It is important to check the content of low ratings, the company’s responses, and the timing of the posts. In particular, Google reviews are useful, but do not make your decision based solely on reviews; consider the construction track record, estimates, and warranty details for a comprehensive judgment.
2. Confirm the presence of warranties and aftercare services
When choosing a contractor, be sure to check for warranties. If repairs are needed within the warranty period, they may be done for free. The duration varies by contractor and paint type, but generally ranges from 1 to 10 years (emergency repairs and partial repairs are often not covered). Some contractors also offer aftercare services separately, so be sure to check for those as well.
Kakeru Koumuten Co., Ltd. provides warranties for eligible exterior renovations and sealing work. The coverage, duration, and details of aftercare services vary by project, so please check the warranty conditions before signing a contract.

3. Obtain estimates from multiple contractors
When requesting renovations, be sure to obtain estimates from multiple contractors. Even for the same work, warranties, aftercare services, and costs can vary significantly. Having multiple estimates makes it easier to negotiate prices.
When comparing estimates, it is important to look at not just the costs but also the “items in the estimate,” “check the undercoat materials, sealing materials, and paint for auxiliary parts,” and “confirm the process.” Lowering the rank of auxiliary parts or skipping steps can reduce costs, so it is crucial to not judge solely based on price.
Click here for detailed points on comparing estimates
4. Confirm whether the contractor performs renovations in-house
Kakeru Koumuten Co., Ltd. conducts detailed hearings and surveys on the existing “condition,” “location,” “materials,” “desired durability,” and “design” to propose a plan suitable for the building and your preferences. While there is no inherent problem with the system in which partner companies perform the construction, it is essential to confirm whether the contracted company understands the construction details and clearly defines the responsibilities for quality control and guarantees. If the construction is done in-house, it becomes easier to coordinate with the site, allowing for a quicker response in case of any troubles.
5. Do they support color simulations and perspective drawings?
Choosing colors and envisioning the look after construction can be challenging for both exterior and interior. With simulations, you can reduce the risk of mistakes like “it turned out differently than I imagined.” Since it is difficult to redo once the construction is done, it is recommended to choose a company that can accommodate flexible simulations.
08Reasons why Kakeru Koumuten is chosen for remodeling used houses in Kita-ku
One reason is that “Kakeru Koumuten also serves Kita-ku,” but
“our unique approach to remodeling vacant and used properties that cannot be imitated by other companies”
has received high praise from many customers.
In remodeling in Kita-ku, we clearly present “cost,” “quality,” and “plans.” Please compare with estimates from other companies.
In remodeling, it is important to obtain multiple estimates and compare them based on the scope of work, materials used, and guarantee conditions.
1. Equipment specialized for in-house remodeling
Kakeru Koumuten has established warehouses and material storage areas to provide remodeling work at appropriate prices and quality. In addition to our headquarters and showroom in Aoba-ku, Yokohama, we have three material storage locations in Aoba-ku and Asahi-ku.
In-house ownership of scaffolding materials
For exterior renovations that require scaffolding, we utilize our owned scaffolding materials and in-house scaffolding team. By handling scaffolding work internally, we can manage the process and reduce costs. We own scaffolding materials for approximately 50 single-family homes.
Materials stored in our large in-house warehouse
We store roofing materials and paints, arranging supplies according to the content and timing of the work. By utilizing our warehouse, we have established a system that facilitates the supply of materials to the site and smooth initial responses in emergencies. We also have a variety of tools ready to handle different types of work, including compressors and cleaning machines.
Sorting of waste materials in-house
In exterior renovations, various waste materials such as paint, wood, and metal are generated. Our company is committed to sorting waste materials and recycling what is possible, striving for proper disposal and cost reduction.
Showroom dedicated to exterior renovations
In the showroom, you can not only have meetings but also check the actual paint colors and a wide variety of catalogs. You can also confirm heat insulation properties using a heat insulation paint testing machine and color simulation. The showroom is a 3-minute walk from Eda Station in Aoba-ku, Yokohama. It is also accessible from within Tokyo.
2. In-house Construction System Focused on Exterior Work
Kakeru Koumuten Co., Ltd. has established an in-house construction system focused on exterior work such as temporary scaffolding, exterior wall painting, and roof renovations. From the estimate to the completion of the work, a dedicated representative will be your point of contact, ensuring coordination with the site and quality control. For interior and equipment work, we collaborate with specialized partner companies as needed. You can confirm the scope of work and construction system during the estimation process.
3. Acquisition of Various Permits and Skilled Workers
We have obtained permits for the construction industry and for the collection and transportation of industrial waste. We also have nationally certified sheet metal workers and painting specialists, ensuring confidence in our construction techniques. We are capable of handling large-scale painting projects for factories and apartment complexes.
4. Warranty and Aftercare Maintenance

09Renovation of Used Properties and Vacant Houses in Kita-ku | Frequently Asked Questions
We answer the most frequently asked questions from those considering renovations of used properties and vacant houses in Kita-ku.
Is it better to consult before buying or after purchasing a used property for renovation?
If possible, please consult us before making a purchase decision. Used properties may have deterioration that is not visible, and it is not uncommon to encounter cases where “unexpected construction costs arose” after purchase. By having Kakeru Koumuten Co., Ltd. check the condition of the property you are considering in advance and provide an estimate of necessary renovations, you can establish a feasible financial plan.
What renovations should be prioritized for a used wooden house in Kita-ku?
It depends on the condition of the building, but we prioritize areas that, if left unattended, could lead to damage, such as leaks, termites, structure, and seismic resistance. After that, we will decide on the order of roof and exterior walls, water areas (kitchen, bathroom, toilet), and insulation based on your budget and impact on daily life. Instead of determining priorities solely based on the age of the building, let’s plan based on the inspection results of the entire building, including the exterior.
I bought a used wooden house in Kita-ku. Can I use subsidies for seismic and insulation improvements?
The subsidy for seismic renovation work for wooden houses in Kita-ku is 2/3, with a maximum of 1 million yen (1.2 million yen for designated areas, 1.5 million yen for elderly households, etc.). Energy-saving equipment subsidies (for window insulation, solar power, etc.) have increased subsidy rates for work done by local contractors, but since Kakeru Koumuten Co., Ltd. is an out-of-area contractor, it will be at the standard rate. There may be cases where you can combine national and Tokyo Metropolitan government programs, but please check in advance for overlapping subsidies for the same work and conditions for application timing.
How much does a full renovation (full renovation) cost?
A full renovation of a detached house varies significantly depending on the total floor area, condition, and quality of the equipment. For updates to the interior and exterior without major changes to the layout, a rough estimate starts at around 8 million yen. In cases of large-scale renovations that reassess insulation, seismic resistance, plumbing, and layout, it can exceed 15 million to 30 million yen. We will first conduct a site survey to assess the condition and propose a plan prioritized according to your budget.
Do I need to apply for subsidies myself? Is the process difficult?
The applicant varies depending on the system. For example, the national “Mirai Eco Housing 2026 Project” has a structure where registered contractors (construction companies) apply. For seismic renovations or home modifications under nursing care insurance in your municipality, the application is generally made by the homeowner, but we will guide you through the necessary documents and process. We will organize and inform you about “which systems can be used,” so please feel free to consult with us first.
What risks are there if I leave a vacant house unattended?
Risks include the progression of leaks and termite damage, depreciation of asset value due to deterioration of the exterior walls and roof, and neglect of garden trees and equipment. Additionally, if you receive a recommendation from the municipality as a “poorly managed vacant house” or “designated vacant house,” there is a possibility that the special tax exemption for residential land will be revoked. Early inspection and necessary work according to your plans to live in, rent, sell, or utilize the property can ultimately help reduce costs.
I am worried about seismic resistance. How can I assess the seismic safety of a used detached house?
The construction date is a significant indicator. Check if it was built after June 1981 (new seismic standards), and further if it was after June 2000 (strengthening of joint and foundation regulations). For wooden detached houses built before that, we recommend a seismic diagnosis. Your municipality also offers subsidies for seismic renovations of wooden houses, which can significantly reduce costs if eligible (for details, see the subsidy section above). Kakeru Koumuten can assist you from diagnosis to renovation.
Will I need temporary housing during construction? How long will it take?
It depends on the scope of the work. Exterior renovations and partial interior work can often be done while you remain in your home. However, for large-scale full renovations that include water areas, we may recommend temporary housing. The estimated duration is about 2 to 4 weeks for exterior work and approximately 1 to 3 months or more for full renovations. We will provide a schedule in advance and propose a plan that minimizes the impact on your daily life.
Is Kita Ward within your service area? Will there be travel costs?
Yes, Kita Ward is within the service area of Kakeru Koumuten. Based on our headquarters and showroom in Aoba-ku, Yokohama, as well as our Machida branch and material storage in Aoba-ku and Asahi-ku, we serve various regions in Kanagawa Prefecture and Tokyo. Please confirm the costs for site surveys and estimates, as well as the service area, when you contact us.

10Features of Kita-ku
Kita-ku, Tokyo, is a town centered around Akabane, Oji, and Jujo, featuring a mix of wooden single-family homes and large-scale housing complexes. The area is characterized by a blend of the Musashino plateau’s cliff lines and lowlands, coexisting with a downtown atmosphere and livability.
For older homes, we consider seismic resistance, insulation, and leak prevention measures according to the condition of the building. Kakeru Koumuten Co., Ltd. is headquartered in Aoba-ku, Yokohama, and we undertake renovations primarily focused on exterior work such as roofing and wall surfaces in various regions of Kanagawa and Tokyo, including Kita-ku.
