Last Updated November 8, 2024
[Notice] <Size criteria> About change of handling of area of stairs
Regarding the standard that "the floor area of at least one floor of the dwelling unit (excluding the area of the stairs) shall be at least 40 square meters."
Until now, in Yokohama City, if the lower part of the stairs can be used as a living space such as toilets, storage, and free space, etc.
Either of the following 12 areas can be excluded from the area of the stairs.
①30% of the area of the stairs
②Parts with a ceiling height of more than 1.4m
However, from July 1, 2022, if the lower part of the stairs can be used as a living space such as toilets, storage, and free space, regardless of 12, the area can be excluded from the area of the stairs. I will do it.
