Thinking about a new fence? Great. But before you dig, make sure it follows London’s rules. Some fences need a permit (like pool fences). Others must meet the Fence By-law (PS-6) for height, materials, and sightlines. This guide shows you what needs a permit and gives you a simple step-by-step to find the forms and apply—fast.
TL;DR: Do I Need a Permit?
- Pool fences: Always need a permit and inspection.
- Regular backyard fences: Don’t usually need a permit but must follow PS-6 rules.
- Over-height fences or special cases: Need an exemption from the City.
Which Fences Need a Permit?
| Fence Type | Permit Needed? | Notes |
|---|---|---|
| Backyard fence | No permit (follow PS-6) | Max height 2.13 m (7 ft), check materials & visibility rules |
| Pool fence | Yes | Requires permit, inspection, and specific safety features |
| Fence taller than 2.13 m | Exemption required | Apply through the City with justification |
