Overview of the System

In Yokohama City, among the first-class and second-class low-rise residential areas, the floor area ratio is 100% or less, but the site is newly divided and built. According to the provisions of Article 53-2, Paragraph 1, Item 3 of the Building Standards Law, construction may be possible by obtaining permission from the Building Examination Committee for those that meet the following permission criteria.

In addition, if it corresponds to the Building Examination Committee Comprehensive Consent Standard, the proposal to the Building Examination Committee can be omitted, and it will be a post-report to the Building Examination Committee.
We revised a part of permission standard and building examination committee comprehensive consent standard about permission of 2 Clause 1 third of Building Standard Act Article 53. In addition, a new explanation of the permission criteria and the Building Examination Committee Comprehensive Consent Base have been added. ＜R4.4.1＞
