The method of measuring unit size
Dear our important clients,
Today, please let me share one knowledge of real estate in Japan with you.
Did you know that the way of providing unit size is different between info sheet and registration certificate?
For info sheet, it is common that size is measured by center line of wall as shown below. This measurement is called 壁芯面積.
The reason why it is used 壁芯面責 measurement is that it is determined by the building standars law.
So when applying for a building confirmation, the floor size is calculated using the center line of wall.
On the other hand, for registration certificate, it is measured by the inside line of wall as shown below. This measurement is called 内法 and it is determined by real estate registration law.
So fixed property tax is calculated based on the inside line of wall.
In conclusion, when you buy a unit property of building, you need to know 2 different way of measurment.
