Buying a Duplex or Triplex in Montreal: Owner-Occupier Guide
Financing a Plex in Montreal
Duplexes and triplexes are a Montreal tradition — the city's iconic housing stock. As an owner-occupier, you can purchase a plex with as little as 5% down on properties up to $500,000 (10% on the portion above $500,000). The lender will factor in potential rental income to help you qualify, typically counting 50–80% of the rental revenue from the other units.
In 2026, average plex prices in Montreal range from $550,000 for a duplex in Verdun or Saint-Henri to $900,000+ for a well-maintained triplex in the Plateau or Rosemont. The math works when rental income covers 50–70% of your mortgage payment, effectively lowering your housing cost below what you'd pay for a comparable condo.
Landlord Responsibilities Under Quebec Law
Owning a plex means becoming a landlord, and Quebec's Tribunal administratif du logement (TAL) governs tenant relations. You must maintain units in good condition, respect lease renewal rights, and follow strict rules around rent increases — the TAL publishes annual guidelines (typically 2–4% depending on costs). You cannot evict tenants simply because you bought the building; eviction for personal use ("reprise de logement") requires specific legal steps and six months' notice.
Budget for unexpected costs: a new roof on a triplex runs $15,000–$25,000, plumbing repairs in older Montreal plexes (many date to 1900–1940) can be $5,000–$15,000, and vacancy between tenants costs a month or more of lost income. A building inspection before purchase is non-negotiable — insist on a thorough one that covers foundation, plumbing, electrical, and roof.
Best Neighborhoods for Plexes in Montreal
Villeray, Parc-Extension, and Mercier–Hochelaga-Maisonneuve offer the best entry prices for plexes in 2026 — duplexes starting around $500,000–$600,000. Verdun and Saint-Henri have risen sharply but still offer strong rental demand near Lionel-Groulx and De l'Église metro stations. For higher budgets, Rosemont and the Plateau command premium prices but deliver reliable tenants and low vacancy rates.

When you buy a plex, your move-in is just the beginning.
