Corner lots usually need a visibility check, not just a height check
A corner property can have more than one street-facing side, and a fence that is acceptable farther back on the lot may be restricted near an intersection, driveway or flanking street. The reason is sightline safety: drivers, cyclists and pedestrians need a clear view where movements cross.
Find the flanking street and driveway first
Before reading a height table, mark the front lot line, the side lot line beside the second street, the driveway and the intersection corner. Municipal rules may use terms such as flanking side yard, corner visibility triangle, sight triangle or visibility area. They do not always describe exactly the same geometry.
Two current examples show the variation
Calgary's current guidance says a fence inside a corner visibility triangle typically needs approval if it exceeds 0.75 m. Edmonton's zoning rules use a special 1.3 m maximum for part of a flanking side on certain corner sites where vehicle access comes from the flanking street. The correct result therefore depends on both the city and the lot configuration.
See the City of Calgary fence guidance and the City of Edmonton fence permit guidance.
Do not copy a neighbour's corner fence
An older fence may pre-date today's rule, may have an approval you cannot see, or may sit outside the visibility area that affects your property. A fence on the opposite corner can also have a different driveway relationship.
What to take to the municipality
If the rule is not obvious, a simple site sketch showing property lines, streets, driveway access, proposed fence length and proposed height makes the question much easier to answer. A survey or real property report is better when the exact boundary or corner geometry is uncertain.
