    Certified BCIN Designers for Architecture & Building Permits in Ontario

    Since 2012, ITI Building Permit Designer Inc. has been relied upon by the industries of Ontario Building Code, interior design, engineering, and construction to assist them in adapting to new technologies and improving the effectiveness of their procedures. From construction permits and builder permits to contractor license, trade license & business licence — ITI Permit handles it all across Hamilton, Toronto, Mississauga, Brampton, Oakville & Niagara Falls.

    Our BCIN Designers in Ontario provide design services & issue construction drawings. If you are unaware of what BCIN stands for, it means Building Code Identification Number, as stated under article 2.17.5.1 of the Ontario Building Code. If you don’t have a BCIN, then you won’t get a building permit.

    The Ministry of Municipal Affairs and Housing began looking into ways to develop a certified body of home designers and expedite the building permit process across all of Ontario near the end of 1999. Bill 124, which went into effect in 2006, was the result of their efforts. This bill also has other requirements that a BCIN designer needs to follow.
