Before you build

Before you set the posts in St. Catharines

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.

From bylaw to the St. Catharines lot

Walk the proposed line from end to end and note where it crosses yard categories, changes grade or approaches a driveway, corner or pool.

Fence compliance and property ownership are different questions. Resolve uncertainty about the lot line before construction.

If the fence protects access to a pool, the dedicated enclosure standard should be part of the design from the start.
