Building Permits regulate all types of construction permitted in the community, and ensure the safety of the property owner, professional contractors and our community at large.

Approved plans must comply with the Ontario Building Code, local zoning by-laws, and other applicable laws and regulations.

Don't have the time or experience to manage your project alone? You can authorize a qualified designer or contractor to obtain the permit on your behalf.

Once the Building Permit is issued, construction may start any time within 6 months from the date of issue. Construction should never start before the Building Permit is issued.
