What's different about basement remodeling in Montreal

Montreal's basement stock reflects the city's building history: about 36 percent of dwellings predate 1960 (17.1 percent pre-1945, 18.9 percent from 1946-1960), and much of that stock is the 2-3 storey brick plex - duplexes and triplexes with a flat roof and an exterior staircase - rather than a detached house. Foundations under these older plexes have absorbed decades of freeze-thaw stress: January averages run -9 to -10.5°C and the city sees roughly 210 cm of snow most winters, so checking the moisture and waterproofing condition of the foundation before any framing or finishing is a standard first step.

Before signing a contract, confirm the general contractor holds a Régie du bâtiment du Québec (RBQ) licence covering residential renovation, since Quebec requires an RBQ General Contractor licence for this trade plus separately licensed electricians and plumbers for their own scope. Finishing a basement into a habitable space also needs a permit from your borough's permit counter rather than a provincial agency, since Quebec issues building permits at the municipal level. Basement work is largely indoor, so bookings tend to rise in fall (September-November) and again in January-February; scheduling in summer, when contractors are busy outdoors, often brings faster availability. That pattern holds whether the project is in Verdun, Rosemont-La Petite-Patrie, or Villeray.

What moves the price in Montreal

  • Pre-1960 plex duplexes and triplexes often need foundation waterproofing checked before a basement finish starts.
  • Flat roofs and exterior staircases common to Montreal plexes can limit basement egress-window options for code compliance.
  • RBQ contractor licensing plus a municipal (not provincial) permit add two separate checks before hiring.
  • Combined 14.975% GST/QST applies to the full labor-and-materials invoice, since Quebec has no labor exemption.

Licensing and permits in Quebec

Licence required. Régie du bâtiment du Québec (RBQ) — General Contractor licence (Schedule I subcategories, e.g. 4043 for residential maintenance/renovation). Verify the contractor's RBQ licence number and that it covers residential renovation/maintenance work before signing a contract.

Residential building permits in Quebec are issued by the local municipality (ville/municipalité), not a provincial agency; each municipality sets its own bylaw thresholds. In Montreal, permits come from the Ville de Montréal — borough permit counters (Permits and Authorizations).

Tax: Labor on home repair/renovation services is a taxable supply in Quebec (no labor exemption) — GST/QST apply to the full invoice including labor, though a partial QST/GST rebate exists separately for new-housing construction or major renovations meeting specific value thresholds.

Best time to book in Montreal

Basement work is indoor and less weather-dependent, so demand rises in fall/early winter (Sep–Nov) and again in Jan–Feb once holiday-season projects wrap; booking in summer, when contractors are busy with outdoor jobs, often gets better pricing and faster scheduling. Peak demand: September, October, November, January and February. Typical job length: 4-8 weeks.

DIY or pro? Homeowners can DIY basic cosmetic work like painting, trim, and flooring, but electrical, plumbing, framing near the foundation, and egress-window work should go to licensed pros — most jurisdictions also require a permit and inspection for a finished basement.

Frequently Asked Questions

How much does it cost to finish a basement in Montreal?

A basic rec-room finish runs about $35-55 CAD per sq ft, a mid-range finish with a bedroom and bath $55-95, and a high-end finish or legal secondary suite $90-150. A full 1,000 sq ft basement remodel typically totals $20,000-75,000 CAD.

Do I need a permit to finish a basement in Montreal?

Yes. Finishing a basement to make it a habitable space requires a permit issued by your borough's permit counter (Ville de Montréal Permits and Authorizations), not a provincial office, since Quebec handles building permits at the municipal level.

What license should a basement remodeling contractor in Montreal, QC hold?

Look for a Régie du bâtiment du Québec (RBQ) General Contractor licence, such as the Schedule I 4043 subcategory covering residential renovation and maintenance, and confirm any electrician or plumber on the job carries their own separate trade licence.
