Outline of permission and certification under Article 43, Paragraph 2 of the Act

　The site of the building must be in contact with the road under the Building Standards Law at least 2m. Therefore, if you do not touch the road under the Building Standards Law, construction will be impossible in principle. However, even if the site is not in contact with the road under the Building Standards Law, if the specific administrative agency recognizes that it will not interfere with the surrounding situation and permits and approves it, it will be possible to build it without meeting the above conditions . This is the permission and certification of Article 43, Paragraph 2 of the Act.
　Until April 30, 1999, the application of Article 43, Paragraph 2 of the Act was determined in the application for building confirmation by the building supervisor, but the permission system was changed from May 1, 1999 due to law revision , A certification system was newly established on September 25, 2018, and permission or certification of a specific administrative agency was required for the application of Article 43, Paragraph 2, Paragraph 2 of the Act.
　In addition, the consent of the Building Examination Committee is required for permission. 　

Is the road-shaped open space pertaining to the permission and certification of Article 43, Paragraph 2 of the Act a road under the Building Standards Law?

　"Roads" in the Building Standards Law refer to those specified in Article 42 of the Act. Therefore, road-like open space pertaining to permission, authorization of Article 43, Paragraph 2 of the Act is not "roads".

If the road in front of the house is a road-like open space pertaining to permission / certification under Article 43, Paragraph 2 of the Act, is it possible to rebuild it?

　Road-shaped open spaces pertaining to permission and certification under Article 43, Paragraph 2 of the Act cannot be treated as roads under the Building Standards Law. Therefore, when rebuilding an existing building, it is necessary to obtain permission or certification. About permission and the right or wrong of authorization and the conditions, prior consultation vote, guide map, present situation neighboring map or present situation survey map (thing which specified width of the present road), official map or cadastral map, registered copy or entry summary Please consult with the City Hall 25th floor, Urban Building Division Building Section Building Permission after preparing documents such as the target road and the land in contact with the road), land area survey map, site photos, etc.

Conditions for obtaining permission and certification

　Permission / certification conditions and site retreat distance are comprehensively determined based on the situation for each project. Permission standards and certification standards are established, but conditions may be added, so prior consultation slips, guide maps, current situation surrounding maps or current situation survey maps (specifying the width of the current road), public maps Or, please consult with the city hall building section 25 after preparing documents such as cadastral map, registered copy or entry summary (those of the target road and land in contact with the road), land area survey map, site photo, etc.

About written oath, written consent necessary when receiving permission, authorization

　Pledges and written consents are documents that the relevant right holders pledge and agree to "maintain and maintain road-like open spaces pertaining to permission and certification under Article 43, Paragraph 2 of the Act in the future." About necessary style and entry method, please talk with city hall the 25th floor, city area building section building permission charge.

About Building Examination Committee Comprehensive Consent Standard

　When obtaining permission under Article 43, Paragraph 2 of the Act, it is necessary to obtain the consent of the Building Examination Committee.
　In order to simplify the permission procedure, Yokohama City has established the Building Examination Committee Comprehensive Consent Standards for General ones. For buildings that meet the Building Examination Committee Comprehensive Consent Standards, the submission to the Building Examination Committee is omitted on permission.
　In addition, consent of building examination committee is unnecessary when we receive certification.

Regarding the necessity of submitting a proposal to the “Building Examination Committee” when obtaining permission

　When receiving permission for those that do not conform to the Building Examination Committee Comprehensive Consent Standards, it is necessary to submit the Building Examination Committee individually and obtain the consent. We have established the Building Examination Committee Individual Proposal Standards as the minimum standard for submitting to the Building Examination Committee. For details, please consult with the City Hall 25F, Urban Area Building Division Building Permission Section.

About the period of the procedure

　For the flow of the procedure, please refer to "Permission / Certification Guided by the provisions of Article 43, Paragraph 2 of the Building Standards Act". It takes 2-4 weeks from "advance consultation submission" to "answer to consultant" (* If deliberation by the Road Judgment Committee is required, it may take 4-5 weeks). In addition, from "permission / certification application" to "permission / certification notification issuance", it generally takes two weeks if there are no defects in site maintenance or application documents. However, this period is only a guide and may vary depending on the situation.

About procedure when building plan is changed after permission, authorization acquisition

　If the architectural plan is changed, in principle, you will need to submit the original permission / certification cancellation notice, and then apply for permission / certification again. However, in cases where minor changes are subject to building confirmation, changes in partition walls, corrections, etc., it may be possible to process by "plan change approval application" or "plan change notification". Please confirm with city hall the 25th floor, city area building section building permission charge about which procedure is necessary by all means.

If the permission / certification under Article 43, Paragraph 2 of the Act is obtained once, is it not necessary to apply for future extension / remodeling / rebuilding?

As permission, authorization of law Article 43 Clause 2 becomes permission, authorization for building, application is necessary every time we perform building act.

If the permission / certification under Article 43, Paragraph 2 of the Act is obtained once, will it be possible to obtain permission / certification even in future extension / remodeling / rebuilding?

　Depending on the subsequent changes in road conditions and the contents of the architectural plan, permission / certification may not be possible or new conditions may occur. In the case of extension or remodeling or rebuilding, prior consultation slip, guide map, current situation surrounding map or current situation survey map (specifying the width of the current road), official map or cadastral map, registered copy or entry summary Please prepare materials such as the target road and the land in contact with the road), land area survey map, site photo, etc., and consult with the City Hall 25th floor, Urban Area Building Division Building Permission Section.
