Do I need a permit to replace my fence in Ottawa?

Yes, you need a building permit to replace a fence in Ottawa if it's over 2 meters (6.6 feet) high, or if you're building a new fence in a corner lot front yard.

The City of Ottawa requires building permits for most fence replacements and installations. Here's exactly what you need to know:

When You Need a Permit:

• Any fence over 2 meters (6.6 feet) in height


• New fences on corner lots facing a street (front yard setback rules apply)


• Fences with retaining wall components over 1 meter high


• Swimming pool enclosure fences (special safety requirements)

When You DON'T Need a Permit:

• Replacing an existing fence under 2 meters high in the same location


• Simple repairs that don't change the fence height or footprint


• Temporary construction hoarding (under 2 meters)

Ottawa Permit Process:
Call City of Ottawa Building Code Services at 613-580-2424 or visit ottawa.ca/building to apply online. A simple fence permit typically costs $100-200 and takes 10-15 business days to process. You'll need a site plan showing the fence location, height specifications, and distances from property lines.

What to Watch For:
Even without a permit, your fence must comply with Ottawa's zoning bylaws. Front yard fences are typically limited to 1 meter high, while backyard fences can be up to 2 meters without a permit. Corner lots have special rules since they have two "front" yards. Always check your property lines - building on your neighbor's property is a costly mistake.

Before You Hire:
Make sure your contractor knows Ottawa's fence regulations and will handle the permit if required. Get quotes that clearly specify whether permit costs are included. Some contractors may suggest skipping permits for replacement fences, but if you're increasing height or changing the footprint, you're legally required to get one.

Official Resources:
Contact the City of Ottawa at 613-580-2424 or check ottawa.ca/building for current permit requirements and fees. For property line verification, consider hiring an Ontario Land Surveyor - it's cheaper than fixing an encroachment issue later.

The permit protects you by ensuring your fence meets safety standards and property line requirements, which is especially important if you plan to sell your home in the future.
