Temporary Fencing Rules for Pool Construction & Excavation

An open pool excavation is a hazard long before water goes in. Temporary fencing rules for swimming pool construction and excavation close that gap by requiring a code-compliant barrier around the work area from the first cut to the final inspection.

We work from one baseline: the temporary fence must be standing before the excavator breaks ground or before any water is introduced, and it must stay in place until the permanent enclosure is approved. Below we walk through the legal obligation, the physical specifications, the timing and notification steps, and the owner’s ongoing duty.

Legal Obligation for Temporary Fencing During Pool Construction and Excavation

Most municipal pool enclosure bylaws and building code sections extend fencing requirements to the construction phase. The rule is straightforward: if an excavation is open or a pool shell can hold water, the owner must erect and maintain a temporary fence that completely surrounds the work area. In practice, that means the barrier must be in place before the hole is dug or at the latest before any water is introduced for testing or backfilling.

Key points to expect in a typical pool enclosure bylaw:

No water may be put into the pool—even for testing—until an approved temporary fence is up.
The owner is responsible for the fence, even if a general contractor installs it.
The temporary fence must remain until the permanent enclosure passes its final inspection.

Core Safety Specifications for Temporary Fencing

Minimum Height and Structural Requirements

The most common minimum height for a pool safety barrier is 1.2 metres (4 feet) above finished ground level. Some local rules go higher—for example 1.5 metres (5 feet)—so confirm the exact number before panels are ordered. The temporary fence must be rigid enough to resist a child’s push or climb. Panels should be installed so they cannot be easily toppled or moved, and horizontal bracing should not create a climbing aid.

Confirm the minimum height with the local permitting office; do not assume 1.2 m is enough.
Use panels with a stable base or weighted feet so wind does not create an opening.
Check that no horizontal rails or bracing provide a foothold.

Gate Specifications: Self-Closing, Self-Latching, and Lockable

Every gate in a temporary pool fence must close and latch on its own. The latch or locking device should be placed high enough—often at least 1.5 metres (5 feet) above the ground—so a small child cannot reach it. Gates must swing outward, away from the excavation, and they must be locked whenever the site is unattended. Propping a gate open, even for a few minutes while moving material, creates the exact hazard the bylaw is designed to prevent.

Test the self-closing hinge and self-latching catch daily.
Keep the gate lock engaged after every entry and exit.
Never remove the closer or tie the gate to a fence panel.

Prohibited Openings and Gaps

A sphere test applies. Openings in the fence fabric, the space under the bottom rail, and any gap around the gate must be small enough that a child cannot squeeze through or get a foothold. Common limits are a maximum 50 mm (2 inches) under the fence and a maximum 100 mm (4 inches) for mesh openings. The goal is to remove any route under, through, or between panels. Inspect joins daily; a panel that shifts out of line can create a prohibited gap.

Set the bottom rail no more than 50 mm off the ground across the full run.
Use fence fabric with openings no larger than 100 mm.
Check panel-to-panel and gate-to-post gaps after every delivery or weather event.

Installation Timing and Notification Requirements

Fencing Installation Timing: Before Excavation or Water Introduction

The temporary enclosure is a precondition, not an afterthought. The fence should be installed before excavation starts so there is never an open, unfenced hole. If the project has already begun, the barrier must be completed before any water goes into the pool shell—including water used for testing, curing, or leak checks. Do not wait for the permanent fence. In many cases, filling the pool without an approved enclosure is itself an offence.

Schedule temporary fence delivery and installation before the excavator arrives.
If excavation is already underway, stop and install the fence before any water is introduced.
Keep the fence in place through backfill, coping, and permanent barrier construction.

Notification and Inspection Requirements for Temporary Fencing

Once the temporary fence is up, the owner must notify the local permitting or enforcement office so an inspector can verify the barrier. The typical deadline is short—often within 24 hours or the next business day of completing the fence. Inspection covers height, gate operation, gap sizes, and whether the fence completely surrounds the excavation. Keep the notification record and any inspection notes on site until the project is finaled.

We supply and install temporary fencing panels that meet these height, gap, and gate rules, and we coordinate the timing so the enclosure is in place before excavation begins.

Ongoing Compliance and Owner Responsibilities

The property owner remains responsible for the temporary fence from the day it goes up until the permanent pool enclosure passes its final inspection. That means weekly and after-weather checks, tightening loose clamps, and re-locking gates. If a panel is damaged or lifted by wind, it must be repaired before work continues. A temporary fence that leaks access is the same as no fence in the eyes of the bylaw.

Walk the full perimeter at least once a week and after any storm or high wind.
Keep the gate locked, and confirm the latch still engages when the gate closes.
Do not store ladders, bins, or stacked materials against or near the fence—they become climbing aids.

If you are planning a pool excavation, get the temporary enclosure in place before the first cut. We can help you schedule delivery and installation so the site is compliant from day one.
