Multiplex Housing

On June 25-26, 2025, City Council adopted Official Plan and Zoning By-law Amendments to enable zoning permissions for residential buildings with up to six units in Toronto & East York District and Ward 23. City Council also adopted the Multiplex Monitoring Zoning By-law. These amendments are now in force.

 

The Multiplex initiative is part of the City’s Expanding Housing Options in Neighbourhoods (EHON) initiative, which looks at ways to create more housing choices in neighbourhoods across Toronto.

A multiplex is a house with 2 to 6 homes (dwelling units) in one residential building. A property owner may be able to convert an existing house or build a new multiplex.

Multiplex Housing at a Glance:

  • A multiplex is a building with 2 to 6 homes.
  • Four-unit multiplexes are permitted city-wide.
  • Six-unit permissions currently vary depending on location.
  • You’ll still need building permits and must meet zoning rules and comply with all City By-laws.

As a property owner, you may be able to:

  • convert an existing house into multiple homes
  • build a new multiplex
  • add more housing on your property.
