The cost of building a home in Quebec

In 2026, most turnkey single-family homes in Quebec fall between $275 and $475 per finished square foot, depending on region, finishes, foundation type and site conditions. Custom architect-designed homes routinely exceed $550/sq ft. Numbers below that range usually exclude land, services, permits, or finishing work — read the fine print.

Two identical floor plans can vary by 40% in final cost. The variance lives in the specification: window quality, envelope performance, cabinetry, HVAC choice, and the depth of the finishing package.

$250k – $400k

Focused renovations, small additions, or a modest turnkey build on owned land in a low-cost region. Standard finishes, tight scope.

$400k – $700k

Mid-size new builds (1,800–2,400 sq ft) with upgraded envelope, quality windows and a considered kitchen. The sweet spot for most Quebec families.

$700k – $1.2M

Signature homes with custom millwork, integrated appliances, refined cabinetry and architectural detail. Access to sister brands EvosBoutiques™ and Atelier Pelissier at this level.

$1.2M and up

Fully custom homes, complex sites, high-performance envelopes (LEED, Passive House-adjacent), landscape integration and long project timelines.

• Land servicing (well, septic, hydro entry, road access): $25k–$120k depending on site.
• Permits, plans, engineering, soil study: typically 3–6% of construction cost.
• GST/QST on new construction (rebates apply under thresholds).
• Landscaping, driveway, fencing — rarely in the base price.
• Escalation clauses on material pricing during long builds.

The most common — and most expensive — mistake is designing a house, then discovering it costs 60% more than intended. Set a total envelope first (land + build + soft costs + 10% contingency), then design within it. A good contractor will tell you what your budget can honestly buy before a single line is drawn.
