Toronto's multiplex rules let most lots hold more homes than owners realize — four units almost anywhere, six in pilot wards, plus a garden suite on a deep lot, and far more on a major street. Here's how to read your lot's potential.
Sample of lots for sale across Toronto.
Since Toronto's 2023 multiplex permissions, most residential lots allow up to four units (a fourplex) as-of-right — no rezoning, no minor variance for the unit count itself. That holds across the old City of Toronto, North York, Scarborough, Etobicoke, York and East York.
In nine Expanding Housing Options in Neighbourhoods (EHON) pilot wards, the limit rises to six units as-of-right. See the sixplex wards to check whether your lot qualifies.
Deep lots can add a garden suite at the rear for one more unit — turning a fourplex into five units or a sixplex into seven, which can open up MLI Select financing.
Lots fronting a designated major street can qualify for a small apartment building well beyond six units — under the avenues/major-street framework, up to roughly 60 units and six storeys, subject to the applicable bylaw and site conditions.
Width, depth, zoning, ward and major-street status all matter, and the only way to know your lot's real number is to check it. Open the map, search your address, and see the as-of-right unit count, buildable envelope and a full proforma in seconds.
Up to four as-of-right on most lots, six in the nine EHON pilot wards, plus a garden suite on deep lots. Major-street lots can support a small apartment building.
Yes. A fourplex is permitted as-of-right on most residential lots city-wide, so no rezoning or minor variance is needed for the unit count.
Check the sixplex wards guide or search your address on the map — it shows your ward and whether six units are permitted.
Unit permissions are as-of-right, but lot width, depth and setbacks determine how much building actually fits. The map shows the buildable envelope for your specific lot.
As-of-right unit potential shown here is a planning guide generated from Toronto's multiplex and Expanding Housing Options in Neighbourhoods (EHON) permissions, not legal advice. Always confirm what a specific lot allows with the City of Toronto or a qualified planner before purchasing or designing.
