Montréal Building Permits & Inspections Guide
This guide explains building permits, inspections and municipal bylaw rules for property owners in Montréal, Quebec. It covers when you need a permit, how inspections work, who enforces the rules and practical steps to apply, pay fees, appeal or report non-compliance. The city and provincial authorities both set standards for construction and safety; read the official application pages and provincial guidance before you start. For official permit pages see the City of Montréal permits information (Permits)[1].
Overview: when a permit is required
Most new construction, additions, structural alterations, certain facade or roof works, demolitions and changes in occupancy class require a building permit. Minor non-structural repairs and routine maintenance typically do not, but local bylaws and zoning rules can apply. Confirm requirements early in planning to avoid stop-work orders or fines.
How inspections work
Permits normally set mandatory inspection stages (footings, framing, insulation, final). The permit or the city inspector will list required inspections and timelines. Keep records of inspection reports and approvals as part of your project file.
- Request inspections through the permit portal or the address listed on your permit.
- Schedule inspections with recommended lead time; same-day requests are rarely available.
- Provide access and required safety measures when the inspector arrives.
