Start with Levis’s current suite guidance
Lévis requires a permit to add a dwelling to an existing residence. The city directs owners to check whether the zone permits the applicable residential use and, where it does not, whether a conditional-use process is available for the property.

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.

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?
Confirm the land-use permission before paying for a detailed design. Province-wide housing changes can still leave property-specific conditions.
Can the building comply?
The building permit tests safety and construction, not just room count. Plan for egress, fire protection and building services.
Can the site serve it?
Site constraints can include parking, sewer and water capacity, electrical service, waste access and setbacks for a detached unit.
The practical Levis suite sequence
Confirm whether the project is an internal suite or detached ADU, then follow the specific zoning and building path for that form.
Existing rental use is not a substitute for permits. Check the city record before assuming the unit can continue unchanged.
