Cranbrook fence rules: permits and height limits

Do I need a permit to build a fence, and how high can it be?

Cranbrook, British ColumbiaChecked against official textSources read 2026-11-05

Short answer

In Cranbrook, a regular fence does not need a building permit, because the Building Bylaw does not apply to fences. The Zoning Bylaw limits residential fences to 1.0 m in the front yard and 1.8 m in other yards, and bans barbed wire in residential zones.

Key facts

PermitNo building permit: the Building Bylaw does not apply to fences. The Zoning Bylaw height limits still apply. A retaining wall under 1.2 m is also outside the Building Bylaw; a retaining wall otherwise needs a building permit designed by a professional engineer.Building Bylaw No. 3725, 2013 (PDF, consolidated April 7, 2025), s. 3.2.3, 3.2.2, 19.1, 19.2 · Wording matched the official text retrieved 2026-11-06

How it works

The Building Bylaw does not apply to fences, so an ordinary fence in Cranbrook needs no building permit. The Zoning Bylaw still controls height and other rules, and fences are exempt from its setback rules (s. 4.08.4). A retaining wall under 1.2 m is also outside the Building Bylaw; other retaining walls need a building permit with a professional engineer's design.

Steps

  1. In any residential zone, keep a front-yard fence to 1.0 m high or less.
  2. Keep fences in all other yards to 1.8 m or less. No fence may be higher than 2.0 m, except open mesh or chain link.
  3. Do not use barbed wire. It is banned in residential zones, except to control livestock in the RT zone (and not where an RT parcel abuts another residential zone).
  4. On a corner lot, keep anything over 1.0 m high out of the triangle formed by the two parcel lines and a line joining points 6.0 m from the corner. The Streets bylaw also bars fences and vegetation in its sight triangle.
  5. Keep the fence in good condition.

Good to know

  • A swimming pool must be fenced at least 1.5 m high with a self-closing, self-latching gate.
  • The City's ticket bylaw lists "Illegal Fence - Residential Zone" at $50 and "Obstruct Vision at Intersection" at $100, and pool fence fines at $250. It cites section numbers from an older Zoning Bylaw, so confirm the current rule.
  • The bylaws set the heights above for residential zones only. For other zones, ask Building Services.
  • The bylaw does not say how to find your property line; confirm it before building (see property-lines).
