Pool fencing in British Columbia must meet specific BC Building Code requirements regardless of whether the pool is above-ground or in-ground, and the rules are strict because pool drownings are a leading cause of accidental death in children under five. For an above-ground pool in Metro Vancouver, the fencing requirements depend on the pool wall height and how accessible the pool is from surrounding grade, but in most cases a compliant barrier fence is required.

The BC Building Code, Section 9.8.8 (Swimming Pool Enclosures) and local municipal bylaws establish the minimum requirements for pool barriers in residential settings. While above-ground pools have walls that provide some barrier function, the rules are not as simple as "the pool wall counts as the fence." Here is what you need to know.

When a Fence is Required for Above-Ground Pools

If the above-ground pool wall is less than 1.2 metres (4 feet) above the surrounding grade on any side, a separate barrier fence is required around the pool to bring the total barrier height to at least 1.2 metres. Most standard above-ground pools sold in Canada have wall heights of 48 to 54 inches (1.2 to 1.4 metres), which technically meets the minimum height — but access points like ladders, decks, and steps that allow easy entry into the pool still need to be gated and secured.

If a deck or platform provides access to the pool, that deck must be enclosed with a compliant barrier — the pool wall height becomes irrelevant because a person on the deck can step directly into the pool without climbing over the wall. This is the most common scenario in Metro Vancouver backyards where homeowners build a deck adjacent to or surrounding an above-ground pool for convenience. The deck perimeter facing the pool must have a gate that meets pool barrier requirements (self-closing, self-latching, opening outward away from the pool).

If the pool has a removable or climbable ladder, the ladder itself creates an access point that must be controlled. Removable ladders can be removed and stored when the pool is not in use, but this is not always considered adequate under local bylaws — many Metro Vancouver municipalities require a permanent barrier regardless of ladder configuration. Check with your municipal building department.

BC Building Code Pool Fence Requirements

The barrier fence surrounding a pool must meet these minimum standards:

Height: Minimum 1.2 metres (4 feet) measured from the finished grade on the outside of the fence. Some Metro Vancouver municipalities require 1.5 metres (5 feet) — check your local bylaw.

No climbable features: The fence must not have horizontal rails, decorative elements, or features that allow a child to climb. This is critical and eliminates many standard fence styles. Chain-link fencing with openings larger than 44mm (1.75 inches) provides toe-holds for climbing and may not comply. Horizontal board fences, lattice, and ranch rail styles are generally non-compliant for pool enclosures. Vertical board fences, vertical picket fences, and solid panel fences with no exterior horizontal rails are the compliant choices.

Gaps and openings: No opening in the fence may allow passage of a 100mm (4-inch) sphere. This prevents small children from squeezing through. For picket fences, picket spacing must be less than 100mm. For chain-link, the mesh opening must be 44mm (1.75 inches) or less.

Gates must be self-closing and self-latching, with the latch mechanism on the pool side of the gate (so a small child reaching over or through the gate cannot operate the latch). Gates must open outward, away from the pool area. The self-closing mechanism must return the gate to the fully closed and latched position from any open position. Gate latches must be at least 1.5 metres (5 feet) above grade, or if lower, must be on the pool side with no opening within 450mm (18 inches) of the latch that would allow a child to reach through.

Costs for Pool Fencing in Metro Vancouver

A compliant pool barrier fence around a typical above-ground pool (round pool with 15 to 24 feet diameter, requiring roughly 60 to 90 linear feet of fencing with one or two gates) costs $3,000 to $8,000 installed. Material options include:

Aluminum ornamental fencing with vertical pickets (no horizontal climbable rails) is the most popular pool fence choice at $45 to $90 per linear foot installed. It is rust-proof, low maintenance, meets code requirements, and comes in heights from 4 to 6 feet. Black powder-coated aluminum with flat-top or spear-top pickets is the standard.

Vinyl privacy fencing at $35 to $70 per linear foot is another compliant option — the solid panels have no climbable features and meet the gap requirements. However, vinyl pool fences block the view of the pool from the house, which some safety experts argue is a disadvantage because parents cannot see children near the pool from inside.

Mesh pool fencing (removable safety fence) at $15 to $30 per linear foot is
