Pick the city and the part of the lot. A number appears only where the current research set contains a clear local height rule; otherwise the tool sends you to the official source.
Choose a city and yard location.
Why some cities do not return a number
Fence rules are not safely reducible to one Canada-wide table. Some municipalities publish a clear front/side/rear chart; others tie height to zoning, setbacks, retaining walls or corner visibility. This checker deliberately refuses to manufacture a number where the source is not simple enough.
