Building a Wood Fence in Calgary: Height Rules, Permits and Planning Tips

How tall can a fence be in Calgary?

According to the City of Calgary, a permit is typically required when a fence goes above these heights:

• Front yard: higher than 1.2 m (4 ft).
• Rear yard: higher than 2 m (6 ft 6 in).
• Inside a corner visibility triangle (the area near a street corner that drivers need to see across): higher than 0.75 m (2 ft 6 in).

Most backyard privacy fences are built at or just under the rear-yard limit, so you get full privacy without needing a permit. If you want something taller, plan for the permit before you order materials.

Do gates need a permit?

The City lists a gate higher than 2.5 m (8 ft 2 in) as another case where a permit is typically required. Standard walk-through and driveway gates built to match a backyard fence are usually well below that height.

Fences near retaining walls

If your yard slopes and the fence sits on or next to a retaining wall, the wall has its own rules. The City says a permit is typically required when a wall retains 1.2 m (4 ft) or more of soil, and walls or garden boxes within 1 m of each other are counted together. Plan the fence and the wall as one project so both are built correctly.

Call before you dig the post holes

Fence posts go deep enough to hit buried gas, power and telecom lines. In Alberta, locate requests go through Utility Safety Partners’ Click Before You Dig service, online or at 1-800-242-3447. Submit the request at least three full working days before digging; Utility Safety Partners notes responses can take 5 to 10 business days in busy periods, so book early in spring.

Know where your property line is

Building a fence on the wrong side of the line is one of the most common neighbour disputes. In Alberta, many homes have a Real Property Report (RPR) from when they were bought, which shows the property boundaries and existing structures. Check yours before you plan the fence layout, and talk to your neighbour early if the fence is on a shared line.

Cedar or pressure-treated wood?

Both are common in Calgary:

• Cedar: naturally rot-resistant, light and attractive. It costs more but ages well, especially if it is stained or sealed every few years.
• Pressure-treated lumber: chemically treated against rot and insects and usually the lower-cost choice. It works well for posts and for fences that will be painted or stained.

Many fences combine the two: pressure-treated posts in the ground with cedar boards and trim above. Whatever you choose, Calgary’s freeze-thaw cycles and dry chinook winds are hard on wood, so a regular stain or sealer extends the life of the fence.
