I am not sure whether I require a building permit - what should I do?

Please contact the Building Department with details of the work you're planning. Our staff will be able to assist you in determining if a permit is required. Making early enquiries about your project will help to resolve any possible issues you may encounter.

Why do I need a building permit?

A Building Permit provides the means to review the project designs, to inspect the actual construction and to ensure that the health, safety and welfare of the occupants of the building are maintained. By reviewing and approving plans before any work is done ensures that construction complies with the Ontario Building Code (which sets minimum standards for design and materials), the local zoning by-law (which controls building location, height, parking, etc. and uses that are suitable to the area) and other applicable laws.

A building permit is a formal approval to construct, add to, or renovate a building on your property. Building permits allow the municipality to protect the interests of both individuals and the community as a whole.

When is a building permit required?

The Ontario Building Code Act requires a building permit when a person constructs or demolishes a building or causes a building to be constructed or demolished. A building is defined as: (a) a structure occupying an area greater than 10 m2 (107.6 ft2) consisting of a wall, roof, and floor or any of them or a structural system serving the function thereof including all plumbing, works, fixtures, and service systems appurtenant thereto,

(b) a structure occupying an area of 10 m2 (107.6 ft2) or less that contains plumbing, including the plumbing appurtenant thereto,

(c) plumbing not located in a structure

(d) a sewage system; or

(e) structures designated in the building code
