Lake Cowichan fence rules: permits and height limits

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

Lake Cowichan, British ColumbiaChecked against official textSources read 2026-11-08

Short answer

In Lake Cowichan the Building Bylaw does not apply to fences, so an ordinary fence has no building permit set out. Under the Zoning Bylaw, fences in residential zones can be 1.2 m in front and 2.0 m at the sides and rear. Pool fences must be at least 1.5 m.

Swimming Pools and Fences

How it works

The Town's Building Bylaw does not apply to retaining structures or fences, so no building permit is set out for an ordinary fence. The Zoning Bylaw (Part IV, Fences and Retaining Walls) states no fence permit requirement. A swimming pool, and so its required fence, does need a permit.

In zones where residential uses are permitted, the Zoning Bylaw sets these maximum heights:

  • Front: 1.2 m.
  • Side and rear: 2.0 m.

The default maximum for a fence or retaining wall is 2.0 m. Height is measured from finished grade to the top; stepped fences are measured at the mid-point between posts. A fence on a retaining wall must stay within the zone's heights, measured from average grade. Fence height is also subject to traffic sight lines.

Steps

  1. Check your zone and property lines before you build.
  2. Confirm the height limits with the Town at 250-749-6681 if your lot is on a corner or in a non-residential zone.
  3. If you are building a pool fence, ask the Building Inspector (ext. 104) about the pool permit.

Good to know

  • On a corner at a highway intersection, no structure may be higher than 1.0 m above the centre point of the intersecting highway within the triangle formed by a line joining points 6.0 m from the corner on each parcel line (Figure 4 in the Zoning Bylaw).
  • Pool fences must be at least 1.5 m high, with self-closing, self-latching gates (Building Bylaw s. 21).
  • Other zones differ: commercial boundary fences and walls up to 2.0 m, and industrial fences must be opaque and up to 2.4 m.
  • The bylaws state no rules on barbed wire, electric fences or hedges.
