Permit rules by project

Pick the project that matches your work. These are starting rules for Repentigny; property-specific zoning, heritage and trade approvals can still apply.

Decks

Depends on scope

Repentigny allows some residential gallery/balcony work through a work declaration, while a gallery or balcony attached to a pool requires a permit. The exact route depends on the project.

Sheds & accessory buildings

Permit required

Repentigny requires municipal authorization for a new shed/accessory building; the City’s current permit page includes sheds and other accessory buildings among regulated residential projects.

Basement renovations

Depends on scope

Repentigny routes many residential renovation scopes through a work declaration, but more substantial or regulated basement work can require a permit. Structural work, new rooms and other scope details can change the route.

Secondary suites & ADUs

Confirm with city

Repentigny does not publish one citywide permit answer for every additional-dwelling-unit project. Confirm the proposed use, zoning and property with Urbanisme.

Interior alterations

Depends on scope

Repentigny allows several interior renovation scopes—such as kitchen/bathroom work and non-load-bearing wall changes—through a work declaration, while other scopes require a permit.

Walls / structural work

Confirm with city

Structural alterations are not safely reducible to the simple declaration examples on Repentigny’s current page. Confirm load-bearing or structural work directly with the City before construction.

Pools / hot tubs

Depends on scope

Repentigny distinguishes pool-related work from simpler residential declarations; pool enclosures and pool-adjacent structures can require permits, while some small-spa work may follow a declaration route.

Garages / carports

Depends on scope

Repentigny regulates accessory buildings, including structures with permanent foundations, through its permit process. Garage/carport requirements depend on the specific structure and property.

Plumbing / HVAC

Confirm with city

Repentigny does not publish one permit answer for every plumbing or HVAC project. Confirm the trade work and any related renovation authorization with the City.

Fences

Permit required

Repentigny explicitly requires a permit to install a new residential fence, change its cladding, move it or add a section. Pool-enclosure rules are separate.

Retaining walls

Confirm with city

Repentigny regulates site and exterior work, but the current City material does not publish one retaining-wall permit threshold. Confirm the wall and site conditions with Urbanisme.

Demolition

Confirm with city

Repentigny’s current permit portal does not give one demolition rule for every residential structure. Confirm the required authorization for the specific building or accessory structure.

Other approvals

Repentigny administers municipal permits/certificates and zoning. Regulated electrical/plumbing/heating/gas trade work also sits within Québec’s provincial contractor-licensing framework, so municipal authorization is not the only compliance layer. Province/authority source ↗

Good to know in Repentigny

  • Major work — including additions, some structural changes, secondary units and other listed projects — still requires a permit and deeper municipal review.
  • Quebec permit terminology and process can vary by municipality—and in Montréal, by borough. Keep the project description precise and check whether the work calls for a permit, certificate, declaration or provincial trade requirement.
