Multiplexes & Additional Units in Toronto
Toronto has expanded the housing types allowed in residential neighbourhoods. Here is a plain-language overview.

Toronto has expanded housing options in residential neighbourhoods. Depending on the property, options can include:
• MULTIPLEXES — buildings with multiple units (such as duplexes, triplexes and fourplexes) in neighbourhoods that once allowed mainly detached houses.
• SECONDARY SUITES — a second unit within a house, often in the basement.
• GARDEN SUITES — a detached unit in the rear yard.
• LANEWAY SUITES — a detached unit on a lot backing onto a laneway.
WHAT THIS MEANS FOR YOU
These options can add rental income or space for family, but each still requires the applicable building permits, and zoning rules still apply.
IMPORTANT
This is general information only, not zoning advice for your property. What is permitted depends on your lot, zoning and existing building. Confirm what is permitted on your specific property with the City before designing.
