Nanaimo fence rules: permits and height limits
Do I need a permit to build a fence, and how high can it be?
Short answer
The City of Nanaimo does not require a building permit for a fence, but it must meet Zoning Bylaw 4500. In most residential zones (R1 to R10, R14, R15) the limit is 1.2 m in the required front yard, 2.4 m in side and rear yards, and 1.8 m on the street side of a corner lot.
Key facts

The Building Bylaw does not apply to retaining structures under 1.2 m.Sources differ: The web page says 'over 4 feet' and the bylaw says 1.2 m (about 3.9 feet); the bylaw is followed here.

How it works
In the City of Nanaimo a fence needs no building permit, but it must comply with Zoning Bylaw 4500, which sets a maximum height by zone and yard. Height is measured from grade on the low side of the fence to its highest part. Barbed wire and ornaments count toward height. A retaining wall counts as a fence for height. Hedges and landscaping are not limited by the fence rules.
Maximum heights
- R1 to R10, R14, R15 and CD9 to CD12 (most houses): 1.2 m within the required front yard; 2.4 m in side and rear yards; 1.8 m in the street-side yard of a corner lot.
- A fence outside the required setback area may be up to 3 m.
- R11, AR1, AR2 and Industrial: 2.4 m. R12 total site: 1.8 m. Next to a park: 1.2 m.
- Commercial Centre zones: 1.2 m front, side and rear. Corridor and Downtown zones: 1.2 m front and 1.8 m side and rear.
- Your zone may have another row in the table. Find it on NanaimoMap or ask Planning.
Steps
- Find your zone on NanaimoMap or call Planning.
- Confirm your property line (see the property lines answer). Build only on your own property, not over rights-of-way or easements.
- At a corner, keep the line of sight clear: nothing may block the view between 1.2 m and 3 m high within the triangle formed by lines 7 m from where the lot lines meet.
- If the fence would be over the limit, ask Planning about a variance.
Good to know
- A retaining wall may need a building permit. The City page says generally when over 4 feet, but other factors apply; the Building Bylaw does not apply to retaining structures under 1.2 m. The two differ, so confirm with Building Inspections at 250-755-4429.
- Exceeding the maximum fence height is a bylaw offence with a $200 ticket ($150 if paid early).
- Pool enclosure fences are set by the Building Bylaw.
- A trellis, gate or arbor up to 2.4 m high and 2.0 m wide marking a pedestrian access may be excluded from the height limit.
