London pool enclosure permit: when you need one and what to submit
The short answer
Yes. Any pool deeper than 75 cm needs a pool fence permit before it goes in, even if a fence is already there. City fee: $12.50 per $1,000 of construction value, minimum $200.

- $12.50 per $1,000 of construction value, minimum $200
- Where to apply
- City of London Development and Business Portal
- Review time
- The City aims to review a complete deck or house renovation application in 10 business days (15 for a second unit).
The fence must be at least 1.53 m (60 in) high, with gates that close and latch on their own. You apply by email to the City's zoning office, not through the building portal.
What an application usually includes
London’s checklist has the exact list; apply through City of London Development and Business Portal.
- A site plan showing the pool, the enclosure and the gates
- A cross-section of the fence with its height and openings
- Gate details: self-closing, self-latching, latch height
- The application, and an inspection before you fill the pool
Local quirks
- A low deck still needs a permit if it's attached to the house. One City list suggests otherwise; the deck page is the one to follow.
- Pool fences must be at least 1.53 m (60 in) high, taller than in many Ontario cities.
- London has opted out of the Line Fences Act: if neighbours can't agree, costs are only shared for a 1.22 m (4 ft) chain-link fence.
