Checker remains nonapproving until applicable zone/lot exceptions are evaluated.

Before you build

Before you set the posts in Trois-Rivieres

Check the fence by where it sits on the lot, not only by its overall height. Front yards, interior side yards, street-facing side yards, rear yards and corner sight triangles can use different limits. A retaining wall below the fence can also change how the municipality measures the combined structure.

Confirm the legal property line before placing posts. Utility easements, rights-of-way and drainage routes can restrict a fence even when its height complies. If the fence encloses a pool or hot tub, use the municipality’s separate enclosure and gate rules rather than relying on the ordinary residential-fence result.

For an over-height fence, unusual material, corner lot or fence on top of a retaining wall, confirm whether a development, zoning, building or variance approval is required before buying materials. The official local source below controls if it differs from this guide.

Trois-Rivières: current official fence source

General residential fence heights have been checked against the linked current municipal source. They are not a parcel-level permit or zoning approval; exceptional zones, street sightlines, pools and grade can change the legal result.

The lot questions that come before height

Front, side or rear?

Use the legal lot layout to determine which yard rule applies rather than estimating from the house orientation.

Corner or driveway?

Mark driveway and street sightlines on the plan before deciding where full-height fencing can begin.

Pool or hot tub?

Ordinary fence permission does not prove a pool enclosure complies. Safety rules can impose different minimums and gate details.

Retaining wall?

If the fence sits on or beside a retaining wall, check whether the municipality regulates the combined height or measurement point.

Before building on a Trois-Rivières lot

If the project includes gates, a driveway or a pool, add those to the lot sketch before using the normal fence-height rule.

Before placing posts on a disputed line, confirm the legal boundary. Municipal fence permission is not a land-title determination.

A yard fence and a pool enclosure are not automatically the same legal object. Verify both rule sets where water is involved.

What the official local guidance actually distinguishes

The official permit guidance lists a separate clôture, haie et muret (fence, hedge and wall) process and requests a site plan plus a location certificate.

The normative urban-planning bylaw (2021, chapter 126) was amended in 2025, including fence/hedge provisions. An old PDF alone is not sufficient proof of a current numerical limit.

Select the lot’s zone and any special provisions, then verify the consolidated bylaw before entering a numeric height into the checker.

This is a planning summary, not property-specific approval. Check the municipality’s current bylaw, zoning, grade, street sightlines, easements and any pool rules before construction.

October 2026 municipal-source review

Indexing candidate after current official bylaw review (October 15, 2026). This is not an approval for any specific lot, pool, corner or fence installation.

Trois-Rivières publishes construction/permit guidance specific to fences, hedges and walls and an urban-planning norms bylaw with slope/grade exceptions (§§618–619 in the 2024 edition). Those exceptions depend on the height table and later amendments; they do not create an unrestricted fence-height entitlement.

Still needed before release: Check current 2025–2026 consolidated articles 615–619/table 23 and determine whether a declaration/permit is required.
