Toronto has changed its rules for small residential buildings. This article outlines the common multiplex sizes, with examples from our upcoming builds.
The rules in brief
Multiplexes of up to four units are permitted on residential lots across Toronto, and up to six units in a number of wards. Larger buildings are possible on larger lots and along major streets, often with additional approvals.
What a specific lot allows depends on its zoning, size, frontage and ward, which is why each lot needs to be reviewed individually.
4+1: five units
Four units plus one additional unit. Because the four-unit permission applies city-wide, this is the most common starting point.
Six-plex: six units
In wards where it is permitted, a six-plex can be built on a standard residential lot. Our Danforth project has three storeys and six units.
Ten-plex: ten units
Larger lots can support ten units at a scale consistent with the street. Examples include Crescent Town and Morningside 1.
Major streets: 16 to 60 units
Lots on Toronto’s major streets can support mid-rise residential buildings. Our six major-street projects range from 12 units at Bendale to 60 units at Bayview Village, 154 units in total.
Factors that determine the number of units
- Zoning and ward — the starting permission.
- Frontage and depth — how much building fits on the lot.
- Street type — residential street or major street.
- Trees, setbacks and access — areas that must remain clear.
- Budget and goals — the maximum number of units is not always the best choice.
