Quebec’s current housing legislation creates a provincial accessory-housing right in defined circumstances, while municipalities retain important siting, construction, architectural, parking and land-development standards and can use available exemptions.

What kind of unit?
Start with the physical form of the second unit; zoning often treats a basement suite and a backyard unit differently.
Is the use allowed?
Verify the current planning permission for this parcel rather than relying on a neighbour’s recent project.
Can the building comply?
A permitted suite needs more than zoning. The building review can address fire separation, exits, alarms, mechanical systems and structure.
Can the site serve it?
Detached units add site questions that internal suites may avoid, including utility runs, setbacks and access through the lot.
For a Saint-Jerome property, check permission before construction
If the unit already exists, begin with its municipal history. For a new unit, begin with zoning and the proposed form before spending on construction documents.
A real-estate listing can describe a suite without proving it is legal. Ask for the municipal approval history before valuing it as an approved unit.
