Wooden House Seismic Diagnosis Subsidy

Expanded the eligible housing

In Inagi City, learning from past earthquakes, we have been supporting the promotion of seismic retrofitting of wooden houses through seismic diagnosis and renovation subsidy projects.

Starting from the 7th year of Reiwa, in addition to the wooden houses built according to the standards before May 31, 1981, newly, wooden houses built using traditional frame construction methods that are single-story or two-story and constructed between June 1, 1981, and May 31, 2000, will also be eligible for subsidies.

If you live in these residences, please take this opportunity to check the seismic resistance of your home.

Eligible Recipients

The following conditions must all be met.

1. The individual must currently own the housing eligible for assistance. However, if the housing eligible for assistance is jointly owned, the individual must have representative authority based on the agreement of all co-owners.
2. All owners of the subsidized housing (if the subsidized housing is a shared property, all co-owners) and all residents living in the subsidized housing (excluding occupants living in collective housing) must not be in arrears on Municipal Tax.

Grant Amount

We will subsidize the lower amount between the cost required for the seismic diagnosis (excluding tax) or 100,000 yen.

Proxy Receipt System

The proxy receipt system is a system in which a diagnostic institution receives grants on behalf of the recipient.
By using this system, you can conduct a seismic diagnosis by paying only the difference between the seismic diagnosis cost and the subsidy to the diagnostic institution.
