A legal duplex or triplex still qualifies for conventional residential financing, but adds rental income from day one — a common entry point for both new investors and owner-occupiers looking to offset their mortgage. Amir Rehmani, MBA, Realtor®, helps buyers confirm what's actually legal before they offer.
A duplex or triplex is only as valuable as its legal status. A property advertised as a duplex with an illegal second unit can mean insurance complications, municipal orders to convert back to single-family use, and a very different resale pool than a properly registered, legal multi-unit property.
Duplexes and triplexes remain one of the more attainable ways into the GTA market — whether as a straightforward rental property or as a house-hack, living in one unit while tenants help cover the mortgage on the others.
Confirm legal status before you fall in love with the numbers.
An advertised 'duplex' or 'legal basement suite' isn't always registered as such — verify before you rely on the rental income.
Up to four units typically still qualifies for conventional financing, with a portion of rental income often countable toward qualification.
Multi-unit fire code requirements differ from single-family homes — confirm compliance as part of due diligence.
Living in one unit versus renting all of them changes both your financing options and your day-to-day involvement.
Career figures below are estimates — ask Amir for current, street-level comparables before you offer.
Your municipality's building department can confirm whether a property has a legal second (or third) unit on file. Never rely solely on a listing description — this should be verified as part of due diligence before you remove conditions.
Often, yes — a portion of the rental income from additional legal units can typically be counted toward mortgage qualification, subject to lender guidelines. Ask Amir or your mortgage broker for specifics based on the property.
