Building Permits and Inspections

What is a building permit?

A building permit is a formal approval to construct, add to, move or remove a building or structure on your property.

The Ontario Building Code Act requires that a building permit be obtained for the construction of a new structure, or an addition or alteration of any structure that results in a building area of more than 10 m2 (108 square feet).

It is illegal to construct or demolish a structure without first obtaining a building permit. Anyone found guilty of building without a permit or has not followed an order issued by a Building Official can be charged under the Ontario Building Code Act.

Why are building permits required?

Building inspections protect the interests of both the individual and the community as a whole. The Building Department ensures that all construction in the municipality meets the Building Code's minimum standards for fire and structural safety standards. The review by a qualified individual also ensures the plans comply with the regulations of the local municipal zoning by-laws as well as all other applicable laws and regulations.
