Yes. Hamilton requires a permit for the pool enclosure (fence) before you excavate or build, and the pool can't hold any water until the enclosure is in place and the City gives final approval.

Pool fence permit rules in Hamilton.
In Hamilton the building permit covers the pool's enclosure, not the pool itself, and it must be issued before any digging starts. The 1.5 m minimum height is measured from the highest ground within 1.0 m of the outside of the fence, which matters on sloped lots along the Escarpment. Pool and equipment setbacks depend on which zoning by-law covers your lot: 05-200, or that of former Ancaster, Dundas, Flamborough, Glanbrook, Hamilton or Stoney Creek. If your lot's final grading hasn't been certified, or the work changes grade by more than 0.2 m within 3 m of a property line, a Site Alteration Permit must be approved first.
Checked against the City of Hamilton'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
You must not excavate or build a pool enclosure until the City issues the permit, and you can't put water in the pool until the enclosure is in place and the City gives final approval. Every swimming pool needs an enclosure.
City of Hamilton: swimming poolsEnclosure height limits
At least 1.5 m (4'-11") high, measured from the effective ground level on the outside, and at least 1.0 m (3'-3") from the nearest inside pool wall. The diagrams on the City's enclosure checklist show 2.0 m (6'-6") as the maximum height of any enclosure.

Every gate needs a self-closing device, a self-latching device on the inside at least 1.35 m above the bottom of the enclosure, and a lock on the inside. A secondary gate used now and then for vehicles or equipment needs only the inside lock. Keep gates closed and locked unless someone is entering, leaving or using the pool.
Pool Enclosure By-law 16-184, ss.17-19 (PDF)No gaps, nothing to climb
No opening may pass a 100 mm sphere, and nothing against or near the enclosure may help someone climb it. Vertical boards: gaps up to 38 mm, or 100 mm board-on-board. The part between house and pool must be see-through, like chain link.

- Enclosure location, height and type, including any existing or shared fences used as part of it
- Walkways, slabs, coping, decks, retaining walls, sheds, septic system (with distance to the pool) and easements on the plan

How it goes
- 1We confirm which zoning by-law covers your lot, the pool and equipment setbacks, the enclosure's 1.0 m clearance from the pool, and whether a Site Alteration Permit is needed.
- 2We draw the scaled site plan with the house, pool, equipment, enclosure, gates and hardscaping, and fill in the City's checklist for your signature.
- 3We submit the Pool Enclosure Permit application in the my.hamilton.ca Customer Portal as your agent.
- 4Once the permit is issued, we build the enclosure to By-law 16-184. A deck beside the pool needs its own building permit.
- 5We request the City's inspection; the pool stays empty until the enclosure is approved.
- Processing time
- Not published for the enclosure permit. If a Site Alteration Permit is needed, it must be approved first; the City quotes about four to six weeks from a complete application to conditional approval, provided no resubmission is needed. The City can revoke a pool permit if the pool and enclosure aren't finished within 12 months of issue.
- Inspections
- An officer must inspect and approve the enclosure before any water goes in the pool, and the City can also require a site inspection before issuing the permit. Inspections for permits filed online can be requested through the my.hamilton.ca Customer Portal (Permitting & Inspections).

Hamilton pool fence permit FAQ
Quick answers.
Under By-law 16-184, an outdoor hot tub that can hold water more than 0.6 m deep counts as a pool. It doesn't need a fence if it has a rigid cover that can support 90 kg (or meets the current ASTM hot-tub standard) and the cover is fastened and locked whenever the tub isn't in use; otherwise it needs a full enclosure. The by-law also says no pool may be built without a permit, and the City's enclosure checklist lists hot tubs and swim spas, so we confirm with the Building Division whether yours needs an enclosure permit.
Yes, if it meets By-law 16-184. The City's checklist asks for a photo of any existing fence used in the enclosure, warns that changes may be required, and wants shared fences on the property line shown on the site plan. A vertical board fence needs gaps of 38 mm or less (100 mm for board-on-board), posts no more than 2.4 m apart set at least 1.2 m below grade in concrete, and the 1.5 m minimum height.
It depends on your lot's zoning by-law. Under Zoning By-law 05-200, a pool or hot tub can't be in the required front yard and must be 1.25 m from every lot line, measured from the water's edge, with pool equipment 0.6 m from the side and rear lot lines. Lots still under a former municipality's by-law differ: former Ancaster and Glanbrook require 1.5 m, while former Dundas and Hamilton allow 1.0 m for an in-ground pool. We check your address before drawing.
