Building a new home is probably one of the most exciting — and most stressful — projects a Quebec family will take on. You dream of a space made to measure, then quickly find yourself facing a sea of plans, permits, quotes and technical decisions. So you don’t have to navigate blind, here are the concrete steps of a new construction project in Quebec, the way they unfold on job sites in 2026.
1. Define the project and confirm feasibility
Before talking about plans, the vision has to be clear. How many bedrooms? What architectural style? What realistic budget? This phase is often rushed, yet it sets the tone for everything that follows. It’s also when you confirm the lot is buildable: zoning, servitudes, soil capacity and access to municipal services.
A good general contractor will ask you these questions early. Skip this step and you’re building on sand — and you pay the bill later.
2. Design the plans and choose materials
With an architect or an architectural technologist, you develop the detailed plans. This is the time to think about solar orientation, interior flow and energy efficiency. In 2026, many clients choose Novoclimat certification, which targets a home that is clearly more energy efficient than the minimum required by the Quebec Construction Code.
You also choose the main materials: siding, windows, roofing, flooring. These decisions affect comfort, maintenance and resale value for the next 30 or 40 years.
3. Permits, surveying and financing
Once the plans are ready, a land surveyor prepares the site plan. With that document and the plans, you file the permit application with your municipality. Timelines vary — expect 4 to 12 weeks depending on the city and the complexity of the project. On a new construction project, plan these steps as soon as the plans are being drawn.
On the financing side, a self-build (construction) mortgage is the most common option. Unlike a regular mortgage, it is released in several draws as the work progresses, and your lender will require inspections at each stage before releasing funds.
4. Site preparation and foundations
The job starts with clearing, stripping and excavation. The French drain and services (water, sewer, electricity) go in, then the slab or foundation is poured. This is the most decisive step for the life of the building: a poorly built foundation means problems for 50 years.
5. Structure, envelope and roofing
Framing, load-bearing walls, roof, windows and doors: this is where the shell goes up. Once the house is “closed in” (weather-tight), interior work is protected and the other trades can move faster.
6. Plumbing, electrical, ventilation
The specialized trades step in: plumber, electrician, ventilation technician. This is where an experienced general contractor makes all the difference — coordinating these teams at the right time avoids weeks of delay and costly rework.
7. Insulation, interior and exterior finishing
Insulation, drywall, paint, flooring, cabinets, tile, exterior siding, landscaping. This phase often represents about 40% of the total schedule. Finishing is when clients finally see their project come to life.
8. Pre-delivery inspection and handover
Before move-in, the pre-delivery inspection provided for by Quebec’s new residential building guarantee plan takes place: the client and the contractor go through every room, ideally with a building inspector, and any deficiencies are documented so they can be corrected. Once the inspection is signed, you get the keys to your new home. This is the step that officially wraps up your new construction project.
How long does a new construction project take?
For a typical residential project in Quebec, expect roughly 4 to 8 months between the start of construction and handover, depending on complexity, weather and material availability. Planning can take another 3 to 6 months beforehand.
