Pool fence permit rules in Ajax.
In Ajax, the pool permit comes from By-law Services under Fence By-law 42-2025, and the by-law applies its pool rules broadly: hot tubs, spas and ornamental ponds count when the water can be more than 50 cm deep. The permit has to be in hand before anything is dug or set up, and the pool stays empty until the 1.5 m enclosure surrounds it. Lots in or near a TRCA or CLOCA screening area need extra documents, and inside TRCA's area its written approval comes first. One of the property owners must complete the HeyJax application; a contractor can't sign as the applicant.
Checked against the Town of Ajax's own by-laws and pages in November 2026. Rules change, so we confirm them for your address before we draw.
Permit before you dig
No one may dig for or set up an outdoor pool or ornamental pond without a swimming pool enclosure permit. Pools include hot tubs and spas whose water can be more than 50 cm deep. No water goes in until the enclosure is complete.

At least 1.5 m high, measured outside and including gates, and within the 2.0 m side and rear yard fence limit.

Gates must match the enclosure, be at least 1.5 m high on substantial hinges, self-closing, and self-latching with the latch on the inside at or near the top. No quick-release that opens from outside. Keep gates closed and locked whenever no one is supervising.

No rails, horizontal or diagonal bracing, or attachments on the outside that would help someone climb, and no gap over 10 cm under the fence. Don't place climbable items against or near the outside unless the whole yard is fenced to the same standard.

The enclosure must be at least 1.2 m from the water's edge, or 0.5 m for an above-ground system pool with a built-in deck and fence. A house wall can be part of it, but any entrance through it needs 1.8 m from the water.

What the city asks for
The Ajax application.
Issued by: Town of Ajax By-law Services (swimming pool enclosure permit under Fence By-law 42-2025). We put the package together, submit it and keep you posted.
Documents
- Swimming Pool Enclosure Permit application on HeyJax, completed by a property owner
- Detailed, accurate site plan with setbacks for the fencing, easements, pool and all buildings
- Pool location and enclosure details
- TRCA's written approval before applying, if the lot is in TRCA's screening area
- Extra documents if the lot is heritage-designated, in or near a TRCA or CLOCA screening area, or on an unassumed road
- Any other documents the by-law officer requires
- Permit fee, paid before the application is reviewed
How it goes
- 1We check whether your lot is in or near a TRCA or CLOCA screening area; inside TRCA's, its written approval comes first.
- 2We measure the yard and draw the site plan: pool, fencing, easements and buildings with setbacks, plus enclosure and gate details.
- 3You submit the application on HeyJax and pay the fee, since the Town requires a property owner as applicant; we prepare everything you upload.
- 4Once the permit is issued, the pool goes in and we build the enclosure: at least 1.5 m high, 1.2 m from the water, with self-closing, self-latching gates.
- 5The pool stays empty until the enclosure is complete all the way around.
- Processing time
- Not published
- Inspections
- Neither the Fence By-law nor the Town's permit page describes an enclosure inspection, though the Town can attach conditions to the permit. The by-law bars putting water in the pool until the enclosure has been erected completely around it, and gates must be kept closed and locked whenever a responsible person isn't supervising.

Ajax pool fence permit FAQ
Quick answers.
Yes. Ajax's Fence By-law counts hot tubs, whirlpools and spas as pools, and the Town requires a permit for a hot tub more than 0.5 m deep. The by-law offers no locking-cover alternative, so plan for the same 1.5 m enclosure with self-closing, self-latching gates.
We prepare the site plan and enclosure details, but the Town requires a property owner to complete the application on HeyJax; a contractor can't sign as the applicant. If your lot is in TRCA's screening area, TRCA's written approval has to come before you submit.
Yes. The enclosure can include all or part of a building wall, but no entrance into the pool area through that wall is allowed unless it's at least 1.8 m from the water's edge, and the building's main entrance can't be inside the enclosure.
