Second Units

Second Units

The City of Mississauga has repealed the current Second Unit Licensing By-law (By-law 204-13) and replaced it with Second Units Registration By-law (By-law 114-16) enacted and passed June 8, 2016.

What is a Second Unit?

A second unit is a self-contained living unit within a detached, semi-detached house or townhouse. As part of the registration process, the second unit must comply with the Ontario Building Code, Ontario Fire Code and the Mississauga Zoning By-law.

Property Owners are required to complete a second unit registration application and submit it at the Planning and Building Customer Services Centre on 3rd Floor, 300 City Centre Drive, Mississauga during regular business hours, Monday to Friday, 8:30 a.m. to 4 p.m.

There is no fee to register a second unit. However, there may be other fees associated with second units such as building permit fees and fire inspection fees as part of the required steps in the registration process. (Note: Not including any required design drawings and renovation costs.)

Homeowners who have already obtained a second unit license will be automatically registered.

If you have a second unit and your property does not appear on the registration list, you will need to register the second unit via one of the streams below;
