Do I need a permit to build a shed, carport, or gazebo in Canada?

Building permit requirements vary across Canada:

• Generally exempt: Temporary/portable structures, structures under 10 sq.m (108 sq.ft.) in many Ontario municipalities, and under 15 sq.m (161 sq.ft.) in some Quebec municipalities
• Usually requires permit: Permanent buildings over 10-15 sq.m, any structure with plumbing/electrical, attached structures
• Always check: Setback requirements (distance from property lines), maximum lot coverage percentages, height restrictions
• HOA considerations: If you live in a community with a homeowners association, check their bylaws in addition to municipal rules

Contact your local building department or check your municipality's website. Having a permit protects you and adds value to your property.
