Calgary’s fence and retaining-wall guide gives several distinct triggers: a fence higher than 1.2 m in the front yard, higher than 2 m in the rear yard, higher than 0.75 m inside a corner visibility triangle, or a gate higher than 2.5 m generally moves into permit review. The front portion is measured relative to the house’s front façade and property line; a side run that passes the front wall may stop being treated like a rear privacy run. A corner lot can lose height precisely where two streets meet even when the adjoining backyard section is compliant.
The City distinguishes planning approval from building safety approval. Most ordinary fences do not need a building permit, but a proposal that misses the Land Use Bylaw standards can require a development permit. Calgary posts a 10–12 week planning-approval timeline on the guide, so a request to relax the permitted height belongs at the beginning of the design, not after the posts arrive. The page also says a new fence must not extend onto City property, and that developer-built fences may be governed by a restrictive covenant on title. If an estate or new subdivision has a uniform developer fence along a park or roadway, read the caveat before removing it.
Calgary treats the retaining wall below a fence as its own engineering question. A wall or closely spaced group retaining 1.2 m or more of soil can require building safety approval; the City explains how to measure the combined wall and fence from grade. A stepped lot cannot be assessed from the tallest visible panel alone. A sensible sketch shows existing and proposed grade, all walls within one metre, the gate, street corner and each property line. Call for utility locates before digging. This makes clear whether the project is a standard boundary fence, an over-height planning application, or a retaining structure with a separate construction review.
