The Ontario Building Code (OBC) administered by the Building and Development Branch of the Ministry of Municipal Affairs and Housing, is the legislative framework governing the construction, renovation and change-of-use of a building. A Building Code Identification Number (BCIN) is required by a designer who engages in the following activities:
- Preparing a design as part of a building permit application
- Giving information or an opinion concerning whether a building or part of a building complies with the Building Code if the information or opinion is to be submitted to a chief building official in connection with a building permit application
- Preparing a written report for submission to the chief building official based on a general review, where a general review is required by the Building Code
A BCIN holder is permitted to engage in the business of providing design activities to the public, subject to the Ontario Building Code and can sign off on all construction drawings and specifications being submitted for permit.
