A. A permit is required for any internal or external change of a residential building, as well as for construction or demolition projects.

Notwithstanding the foregoing, some maintenance repairs or replacement works which have no impact on the safety of people may not require a permit. To name a few:

  • Painting, changing carpets or other flooring;
  • Minor surface repairs of exterior walls (brick joints, etc.), without replacing the full wall facing;
  • Resurfacing of the roof membrane or shingles without touching the insulation or roof structure;
  • Replacing kitchen cabinets or counters, bathroom fixtures or ceiling mounts, without touching the plumbing;
  • Landscaping: trees, hedges, fences, including ground-level unistone that is not used for vehicle parking.


To determine whether a permit is required and to ensure the conformity of the work, citizen should communicate with the Permit Department of the concerned borough.

For works relating to electricity or heating systems (electrical or natural gas), you must consult the Régie du bâtiment du Québec web site or call Services Québec at 1 800 363-1363.
