1981: The Seismic Line
Buildings approved from June 1981 adhere to the new seismic standard (新耐震), while those before are stuck in the riskier "old standard" (旧耐震) stock. This divide affects financing and resale as many banks and buyers avoid 旧耐震 buildings, leading to deep discounts on older condos. One date on the building certificate changes safety, financeability, and resale value.
The takeaway: knowing the building's birthdate can save you from seismic surprises.
