Do I need a permit to build a fence?

Yes, you typically need a permit to build a fence in Ottawa, but it depends on the height and location. The City of Ottawa requires building permits for most fences over 1 meter (3.3 feet) high, and there are specific setback requirements from property lines.

Ottawa Fence Permit Requirements

For fences over 1 meter (3.3 feet) high, you need a building permit from the City of Ottawa Building Code Services. The permit fee is typically $100-200 depending on the fence length and complexity. Simple residential fence permits usually take 10-15 business days to process.

Fences under 1 meter high generally don't require permits, but you still must follow setback requirements and ensure you're building on your own property. Corner lots have additional visibility restrictions near intersections.

Step-by-Step Process in Ottawa

First, call Ottawa Building Code Services at 613-580-2424 to confirm your specific requirements, as rules vary by neighborhood and zoning. You can also check preliminary requirements at ottawa.ca/building.

Before applying, you'll need a survey or site plan showing your property boundaries, proposed fence location, and distances from property lines. The fence must typically be set back at least 0.3 meters from your property line, though this varies by area.

Submit your permit application through the City's online portal or in person. Include your site plan, fence specifications (height, materials, gate locations), and the permit fee.

What to Watch For

Never assume your property lines - many fence disputes arise from homeowners building on neighbors' property. Get a current survey or have your boundaries marked before starting.

Check for underground utilities by calling Ontario One Call (1-800-400-2255) at least five business days before digging. This free service marks gas, electrical, and water lines.

Verify contractor licensing if hiring someone. While fence installation doesn't require specialized trade licensing, ensure your contractor has WSIB coverage and liability insurance. Check their WSIB clearance at wsib.ca/clearances.

Neighborhood Considerations

Different Ottawa neighborhoods have varying restrictions. Areas like Kanata, Orleans, and Barrhaven may have additional community association guidelines. Heritage districts in central Ottawa often have stricter requirements for fence materials and styles.

Pool fences have separate, stricter requirements under Ontario's Building Code, requiring permits regardless of height and meeting specific safety standards for gates and latching mechanisms.

Official Resources

Contact City of Ottawa Building Code Services at 613-580-2424 or visit ottawa.ca/building for current permit applications and fee schedules. The building department can also clarify setback requirements for your specific property and zoning.

Getting the proper permit protects you from potential bylaw violations and ensures your fence meets safety standards, especially important if you plan to sell your home in the future.
