Information on Yokohama City Condominium Seismic Diagnosis Support Project ※Application for 2024 has been closed.

About application of 2024

The Great Hanshin-Awaji Earthquake also caused severe damage to condominiums (especially those in the form of pyrotei), and the lack of subsequent rebuilding and renovation has become a major problem.
Condominiums occupy a large position as a form of living in Yokohama City, but those constructed according to the standards before the new seismic design due to the revision of the Building Standards Law in 1981 may not have sufficient earthquake resistance. It is considered. Therefore, we believe that it is important to promote seismic diagnosis of condominiums in order to promote disaster-resistant town planning, and we have been conducting surveys and examinations so far.
Then, a preliminary diagnosis (simple diagnosis) was established in September 1998, and a subsidy system for this diagnosis (precision diagnosis) was established in April 1999.

As shown in the Piloti format diagram, a building consisting of only pillars and has floors without walls is called the Piloti format. In many cases, this part is used as a parking lot or bicycle parking lots.
