1
Determine if a permit is required
Use Gatineau's URBAIN virtual assistant to check whether your project requires a permit. Most structural work, additions, and major renovations require a permit under the Quebec Construction Code.
-
2
Check zoning with Géoportail
Use Gatineau's Géoportail urbanisme interactive map to verify your property's zoning. Confirm setbacks, lot coverage, and permitted uses before preparing your application.

3
Check for heritage designation
Gatineau has heritage sites including the Quartier-du-Musée and Site patrimonial du Portage, plus 600+ heritage buildings in the Hull sector. If your property is designated, additional approvals apply.
-

Prepare your application
Collect required documents: site plan, floor plans, elevations, and any engineering reports. Use URBAIN to get a customized checklist for your project type.
-
5
Submit through URBAIN or in person
Submit your permit application through the URBAIN online portal or at the Service de l'urbanisme. Fees are defined in Règlement 501-2005.

Arrange RBQ-regulated work

Schedule inspections
Once your permit is issued, schedule inspections through the Service de l'urbanisme at 311 or 819-595-2002. RBQ-regulated work requires separate inspections coordinated by your contractor.

When do I need a building permit in Gatineau?
Gatineau requires permits for most construction, renovation, and demolition work. This includes structural changes, additions, finishing basements, decks, and exterior modifications. Use the URBAIN virtual assistant to check your specific project.
How do I apply for a building permit in Gatineau?
Gatineau accepts permit applications through the URBAIN online portal or in person at the Service de l'urbanisme et du développement durable (SUDD). URBAIN guides you through the requirements and generates a customized application checklist.
How long does it take to get a permit in Gatineau?
Unlike Ontario, Quebec has no statutory review timelines for building permits. Typical processing time in Gatineau is 20-30 business days for residential permits, depending on completeness and complexity.
What is the RBQ and do I need an RBQ license?
The Régie du bâtiment du Québec (RBQ) is Quebec's provincial construction regulator, equivalent to Ontario's ESA and TSSA combined. Contractors need an RBQ license for most work. Homeowners are exempt when working on their own primary residence.
Do I need separate permits for electrical work in Gatineau?
In Quebec, electrical work is regulated by the RBQ, not a separate authority like Ontario's ESA. Your RBQ-licensed electrician handles the regulatory requirements. This is coordinated through your contractor, not a separate permit application.
What about gas work in Gatineau?
Gas work in Quebec is also regulated by the RBQ (not TSSA as in Ontario). Hire an RBQ-licensed gas technician who will ensure compliance with Quebec's gas installation requirements.
Is my Gatineau property in a heritage area?
Gatineau has designated heritage sites under Quebec's Loi sur le patrimoine culturel, including the Site patrimonial du Quartier-du-Musée and Site patrimonial du Portage. The Hull sector has 600+ heritage buildings (maisons allumettes). Check Gatineau's heritage registry if your property may be affected.
What is a dérogation mineure (minor variance)?
A dérogation mineure is Quebec's equivalent to Ontario's minor variance. If your project meets building code but doesn't comply with zoning, you can apply for a minor variance through Gatineau's Comité consultatif d'urbanisme (CCU).
