Swimming Pool

Do I Need a Building Permit?

You do not need a Building Permit to install a swimming pool.

You do need a Building Permit to:

construct the pool enclosure (fence)
construct a deck in addition to or adjacent to the pool

Pool enclosures are required for all swimming pools.

You do not need a Building Permit to install a swimming pool, however you do need a Building Permit to construct the pool enclosure (fence). Pool enclosures are required for all swimming pools. The pool enclosure must be in accordance with The City of Hamilton's Swimming Pool Enclosure By-law No. 16-184(PDF, 68.94 KB) with Amendment By-law No. 22-059(PDF, 124.28 KB).

You must not excavate or build a pool enclosure until you get a Building Permit. Do not put water in the pool until you have the swimming pool enclosure in place and you receive final approval from the City.

The Swimming Pool Enclosure Checklist(PDF, 641.28 KB) is required to be completed and submitted with the Enclosure Permit Application. If a Site Alteration Permit is required, it must be approved though the Growth Management Division prior to the issuance of the Enclosure Permit.

If you are planning on repairing or replacing an existing pool enclosure (fence) contact the Building Division to determine if a permit is required at 905-546-2720 or [email protected]

Note: If a deck is constructed in addition to or adjacent to the pool, a separate permit will be required for the deck.

Enclosure Requirements

The fence must have a minimum vertical height of 1.5 metres (4’-11”), measured from the effective ground level on the outside of the enclosure,
It must also be located at least 1.0 metre (3’-3”) from nearest inside pool wall,
Has no opening when all gates are closed allowing the passage of a spherical object larger than 100mm in diameter,
Has nothing against or near the enclosure that facilitates climbing the enclosure or diminishes the structural integrity of the enclosure,
Every fence and gate used as part of an enclosure which forms the part of the enclosure that separates the pool from any dwelling on the same property shall be constructed of open mesh chain link fence or equivalent open face construction that does not restrict visibility of the pool from any door or window that is located on the access level of the dwelling, and which has a line of sight to the pool, and the materials used shall comply with the provisions of By-law 16-184.
Any gate that forms part of the enclosure must be equipped with a self-closing and self-latching device at the top of the gate on the inside of the enclosure.
