Do deck and patio projects require inspections in Ottawa?

Most deck and patio projects in Ottawa do require building permits and inspections, but it depends on the height, size, and construction details.

For decks in Ottawa, you need a building permit if the deck is:

• More than 24 inches (600mm) above grade


• Attached to your house


• Over 108 square feet (10 square meters) in area

The City of Ottawa Building Code Services (613-580-2424) requires inspections at key stages: footing/foundation inspection before concrete is poured, framing inspection before decking is installed, and final inspection upon completion. A typical deck permit costs $200-400 and takes 10-15 business days to process through ottawa.ca/building.

Patio projects have different requirements depending on construction. Simple ground-level patios using pavers, stones, or basic concrete typically don't require permits. However, you'll need a permit for raised patios over 24 inches high, patios requiring structural footings, or those involving electrical work for lighting or outlets.

What to watch for when hiring contractors for these projects: Ensure they mention permit requirements upfront - any contractor who says "we don't need permits" for an elevated deck is a red flag. Verify they're properly insured and have WSIB clearance through wsib.ca/clearances. Get detailed quotes that specify who pulls permits and schedules inspections.

The inspection process typically involves the contractor scheduling inspections through the City's online portal. Failed inspections mean work stops until corrections are made, so hiring experienced contractors familiar with Ottawa's requirements saves time and money.

Electrical considerations: If your deck or patio includes lighting, outlets, or a hot tub, you'll also need an ESA (Electrical Safety Authority) permit. Only Licensed Electrical Contractors can pull ESA permits - verify licensing at esasafe.com/contractor-locator. ESA inspections cost approximately $100-200.

For specific permit requirements for your project, contact City of Ottawa Building Code Services at 613-580-2424 or use the pre-consultation service. They can clarify whether your specific deck or patio design requires permits based on your property's unique circumstances.

Remember that permits protect you - they ensure proper construction methods, appropriate materials, and compliance with safety codes. Unpermitted work can cause issues with insurance claims and home sales later.
