Permits & Rules
Do I Need a Permit for a Fence in Toronto? (Height Limits and Bylaws)
Most standard residential fences in Toronto do not need a building permit. But every fence must comply with the Toronto Fence Bylaw (Municipal Code Chapter 447): roughly 2.0 m maximum in rear and side yards, about 1.2 m in front yards near the street, no prohibited materials, and visibility rules on corner lots. Want to go taller? That requires a Fence Exemption Application with a $200 non-refundable fee, and your neighbours are notified. Pool enclosures are the other exception: those always need a permit.
Height limits at a glance
| Location | Typical max height |
|---|---|
| Rear yard | 2.0 m (6'6") |
| Side yard | 2.0 m |
| Front yard near the lot line | ~1.2 m (4 ft) |
| Privacy screen on an uncovered deck | 2.0 m above the deck surface |
| Pool enclosure (single residential) | Minimum 1.2 m, with strict gate rules |
Heights are measured from grade. Corner lots have additional open-construction requirements near driveways and intersections so drivers and pedestrians have sightlines.
Materials you can't use
Chapter 447 prohibits barbed wire, sheet metal, and electric fences on residential property (electric is allowed only in agricultural contexts). Using a prohibited material can earn you a Notice of Violation and an order to remove or replace the fence at your own cost.
Going taller: the Fence Exemption
If you want a fence above the bylaw height, say 2.4 m for privacy from a neighbouring three-storey addition, you apply for a Fence Exemption:
- $200 fee, non-refundable whether or not it's granted
- Adjacent neighbours are notified and can speak at the Community Council hearing
- Your name and address become part of the public record
- Written support letters from neighbours meaningfully improve your odds
- If denied, the fence must come down to compliant height
Practical translation: get your neighbours onside before applying, or design within 2.0 m. A 2.0 m fence plus a row of cedars often achieves the same privacy without the hearing.
Privacy screens on decks
A useful and little-known provision: privacy screens on uncovered decks can rise up to 2.0 m above the deck walking surface. On a raised deck that can put the screen top well over 3 m above grade, legally, because it's measured from the deck, not the ground. This is often the cleanest solution to an overlooking-neighbour problem.
When a fence does need a permit
- Pool enclosures: always. Covered in our pool fence requirements guide.
- Retaining wall combos: a fence atop a retaining wall can trigger structural review depending on heights.
- Right-of-way work: posts or staging on City property (boulevards, laneways) need street-work permissions.
- Heritage districts: material and style restrictions can apply; check before ordering.
The rule we see missed most often is the corner lot one. On a corner, the height limits near the intersection exist so traffic can see across to the next leg of the junction, and it's remarkably easy to forget in Toronto, where corner lots are everywhere. People grow trees and bushes into that sightline too, but plantings can be trimmed back; a fence built into it is a permanent problem that can end with an order to alter or remove it. If your lot touches a corner, check the visibility requirements before a single post goes in.
FAQ
What's the tallest fence I can build without any city involvement in Toronto? 2.0 m in rear and side yards, built with permitted materials, off corner-lot sightlines.
Do hedges count as fences? Mostly no. Toronto removed height limits for hedges and shrubs acting as fences, except within 2.4 m of a lot line along a public road.
My neighbour's fence is over 2 metres. Can I report it? You can file a complaint with the City (311). Bylaw enforcement is complaint-driven; the City doesn't patrol for tall fences.
Do other GTA cities have the same rules? No. Mississauga, Vaughan, and Markham each have their own height limits and permit thresholds. Always check the local bylaw office.
