Question title: About the occupancy rate of semi-squared land

Today, I attended the seminar. Thank you very much. Among them, he spoke about the land of the crank (L-shaped land), "Because it is not a corner lot, there is no easing of the building coverage ratio." However, as a result of a survey on the Internet, it is described as follows.
2. Site for real estate appraisers ( of Naito Office)
Then, the L-shaped land is a "quasi-corner" according to the Building Standards Act. There is also a statement that the occupancy rate is not eased on two routes, but on a semi-square ground.
10. My home (Tokyo) is actually L-shaped, but the important matter statement states that the building coverage ratio has been eased, and the XNUMX% limit has actually increased.
XNUMX. There is information on relaxation of building coverage by corner lots etc. (Article XNUMX, Paragraph XNUMX, Item XNUMX of the Building Standards Act) on the pages of government offices in Tokyo, Kanagawa, etc. These specify the range of corner lots, etc., but the L-shaped cranks are quasi-corner areas, and all stipulate the mitigation of the building cover ratio.
From the above, correctly, the Building Standards Law stipulates the mitigation of the occupancy rate only for corner lots, but the handling of corner lots etc. is stipulated in the detailed regulations, and quasi corner lots are also subject to relaxation, Isn't that that? If there are local governments that do not include the crank in the handling of corners etc. in the detailed regulations, please let us know.

Thank you for coming to our seminar yesterday!

Thank you for coming to our seminar yesterday! This is Tokuda of Rich Road!

I just contacted the Shinjuku City Office Building Examiner and found that my recognition was incorrect.

First of all, "corner" means T-shaped road and crossroad, and L-shaped (crank-shaped) is also called "corner". (By the way, there is no word "quasi-square ground.")

Regarding the mitigation of the occupancy rate, it is said that in Tokyo, each ward is stipulated. For example, in Shinjuku ward, it is stipulated in "Shinjuku City Building Standard Law Enforcement Regulations Article 45".

There are some rules that can be relaxed, such as that the angle at which two roads intersect is less than 2 degrees or that more than 120/1 of the circumference (length around the site) faces the road That's right.

In addition, there seems to be a reduction in the occupancy rate on two-sided roads, but the conditions seem to be severe, as both roads are more than 2m wide.

I am sorry to say something wrong because of my lack of study. Thank you very much for your comments this time! I will study hard from now on and I will do my best to be able to tell the right story!

Thank you for this time!
