Can I install a wood stove in my detached garage in Ottawa and what permits does Ontario require?

Yes, you can install a wood stove in a detached garage in Ottawa, but it requires careful attention to Ontario Building Code requirements, proper clearances, and several permits. The installation must meet the same safety standards as a residential wood stove, with additional considerations for the garage environment and potential storage of flammable materials.

The Ontario Building Code allows wood stoves in detached garages provided they meet specific clearance requirements and safety standards. Your wood stove must maintain minimum clearances to combustible materials — typically 36 inches from the front, 18 inches from the sides and back for most units, though these distances vary by manufacturer and can be reduced with proper heat shields. The garage's concrete floor provides adequate non-combustible flooring, but you'll still need a proper hearth pad extending at least 18 inches beyond the stove opening and 8 inches on the sides and back. Wall protection using cement board or other approved materials is essential where clearances are reduced.

You'll need a building permit from the City of Ottawa for the chimney installation and potentially for the stove installation itself. Call 3-1-1 or visit ottawa.ca to confirm current requirements, as garage installations sometimes trigger additional review. The chimney must follow the 3-2-10 rule — extending at least 3 feet above the roof penetration point and 2 feet higher than any structure within 10 feet. A WETT-certified installer should handle the installation to ensure insurance compliance, and you'll want a WETT inspection afterward to document that everything meets code.

Special garage considerations include ensuring adequate combustion air supply (garages are often tightly sealed), proper storage of any flammable materials well away from the stove, and installing smoke and carbon monoxide detectors. Never store gasoline, paint, or other flammable liquids in a garage with a wood stove. Ottawa's extreme cold makes garage heating appealing, but the investment typically runs $4,500 to $8,000 for a complete installation including the stove, chimney system, permits, and professional installation.

When you're ready to move forward, you can browse WETT-certified installers through the Ottawa Construction Network directory to get quotes and ensure your garage wood stove installation meets all Ontario requirements safely.
