Building permits are issued by Building Services and are reviewed for compliance with the Ontario Building Code and the other applicable provincial and municipal regulations. Building permits are also required to guarantee compliance with Zoning By-laws and other Applicable Law (Building Code Act; Section 18.104.22.168).
By obtaining a permit you can also utilize the professional expertise of the Building Services staff. Our Inspectors and Plans Examiners are certified and skilled with extensive training in Building Code regulations. They serve as excellent sources of knowledge and can provide suggestions to assist in resolutions to construction issues, often before they occur; consequently, saving you project time and money.
The Building Code Act requires that a building permit be obtained for the construction of any new building having a building area of more than 10m2 (108 square feet). It is illegal to construct or demolish without first obtaining a permit.
