Quebec City: the local suite starting point
This Quebec City entry has a general official permit/zoning route rather than a verified project-specific suite page. Use it to confirm the address, unit form and current approval path.

Quebec: the provincial layer
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.
Quebec accessory-housing provincial framework ↗Before drawings: four approval questions
What kind of unit?
The approval route can change depending on whether the new home is internal, attached or detached from the main dwelling.
Is the use allowed?
Establish that the unit form is allowed on this parcel before solving construction details or applying for trade permits.
Can the building comply?
A second dwelling can trigger code work in walls, ceilings, exits and mechanical systems even when the zoning is straightforward.
Can the site serve it?
Detached units add site questions that internal suites may avoid, including utility runs, setbacks and access through the lot.
A better Quebec City planning order
Move from planning to construction deliberately. A favourable zoning answer still needs code-compliant drawings, permits and completed inspections.
For resale properties, the most useful evidence is the municipal file, not the number of years the unit has been rented.
