Mayfair Homes, after preparing the architectural house plans and assurance of compliance with the Ontario Building Code, local Zoning Bylaws, and other applicable regulations, submit your application to the city for approval. Consult our architect for the city of Toronto building permit approval which is $16/sq meter for additions and $4/sq meter for alteration in the existing structure.
