Your Complete Guide to Exterior Siding Standards: Ahuntsic-Cartierville

Minor Repairs and Maintenance

When it comes to maintaining or conducting minor repairs on your property's exterior, it's good to know that you don't need a permit if you're using materials that match the existing ones in color, texture, and form.

Replacing Exterior Siding

If you're considering changing, either partially or entirely, the exterior siding of your building, it's crucial to obtain a permit. This applies even if you're only altering the color, texture, or form of the siding. Moreover, based on Québec’s building code, there might be a need for non-flammable materials.

Materials to Avoid

It's essential to be aware of the materials that are not allowed for exterior siding:

  • Plastic membranes, tar paper, mineral or vinyl surface roll roofing, and similar materials
  • Particleboard panels or any material not intended for outdoor use or that appears unfinished
  • Glass, mirrors, or any other material reflecting more than 20% of daylight over more than 5% of a facade's surface, including openings
  • Asphalt shingles, except when used for coping
  • Transparent panels and solariums made of flexible polycarbonate membranes or other plastic materials are not allowed in all zones.

Aesthetic of Buildings

In most scenarios, a building's facade should be 80% covered in masonry, and this masonry should extend to some parts of the side walls. However, for standalone buildings situated in zones that only allow single-dwelling structures (category H.1), these guidelines don't apply.

For semi-detached or adjoining buildings, the exterior facing that reaches the shared boundary with a similar structure should have a consistent form, color, and texture. If your building is in a heritage zone or site, there might be additional requirements. It's always a good idea to check with the permit counter to understand the rules specific to your situation.

Permit Costs

The fees associated with obtaining a permit depend on the estimated cost of the work. Here's the breakdown:

  • $9.80 for every $1,000 of projected work
  • A minimum of $157 for exclusively residential buildings
  • A minimum of $462 for commercial, industrial, institutional, or mixed-use buildings

It's essential to include all associated costs in your estimate, including taxes. There might be extra charges if your building is in a historic area or if it needs to adhere to particular architectural standards. Remember, these fees are non-refundable.

Documentation Needed

To process your request, you'll need to provide:

  • A detailed bid or cost projection for the work, inclusive of taxes
  • A certificate of location
  • Updated color photos of the facades of neighboring properties
  • Recent color photos of the facades impacted by the work
  • Any other document deemed necessary for the application

If the renovations are in a condominium:

  • An authorization letter from each owner or a resolution from the condominium board
  • If you're acting as a proxy, a power of attorney that allows you to represent the owner is required.
