New City webpage for building additional units

As part of our Housing Action Plan, the City has updated its zoning rules to make it possible for homeowners to build more homes on their property. This means, it’s easier for residents with a detached, semi-detached or town house, to build:

  • ​Up to two additional residential units – such as garden suites, garage conversions, apartments, etc. – in addition to their primary home; or
  • A new purpose-built fourplex (or fourplex conversion)

While not all properties are suitable, our research shows that a detached ARU is permitted on more than 130,000 residential lots in Mississauga. And many other homes could be converted to accommodate a second or third unit.

The City has launched a new webpage to help residents determine whether building an ARU or fourplex makes sense for them. Visit mississauga.ca/building-more-units​ to learn more.
