Second Units

New policies and regulations for Second Units were approved by City Council on Monday, April 1, 2019. and are now in effect (as of May 2019).

Examples of second units: basement apartment, second floor apartment, garage suite, coach house.

As required by the Province, Second Units will be permitted in single detached, semi-detached and townhouse dwellings, in both urban and rural areas.

Second Units can be built as an apartment within a house (like a basement apartment), as part of an accessory building to the main house (like a garage suite), or as a standalone accessory building (like a coach house).

All new Second Unit construction will require a Building Permit from the City’s Building Division.

Learn more at our public information session on Tuesday, February 26 from 4 to 7 PM come-and-go at Elim Pentecostal Tabernacle - 306 McNabb Street (see on Google Maps).

The final report to City Council containing the recommended policies and regulations is now available below. To submit a written comment, please email Peter Tonazzo, Senior Planner at p.tonazzo@cityssm.on.ca with your name and mailing address by Monday, April 1.
