You do not need a building permit when you:
- construct any detached structure less than 10 square metres (107 square feet) or a shed accessory to a residential use only under 15 square metres (160 square feet) in size, these structures must comply with other applicable by-laws (e.g., zoning), regulations and contain no plumbing
- replace shingles or steel roofing, or replace exterior cladding, unless structural work is undertaken, insulation is added or air barrier is added
- install eaves trough
- paint or decorate
- erect a fence, unless it surrounds a swimming pool
- install, replace or alter electrical fixtures (excluding smoke or CO alarms). Note that an inspection by the Electrical Safety Authority may be required
- demolish a farm building on an active farm
- tents smaller than 60 sq metres that are used for personal or non-commercial use
Although a building permit may not be required, zoning by-laws still apply and your project may require planning approval or approval from other agencies. Please contact us before starting any construction or demolition project. Structures built without a permit may be subject to increased fees.
