|Second units are part of the City’s affordable housing strategy. A second unit is a self-contained living unit within a detached, semi-detached house or townhouse. They are also called basement apartments, in-law suites or secondary suites. Ontario laws now require municipalities to allow second units in homes.
Mississauga City Council approved a plan to permit second units on July 3, 2013. The plan includes official plan policies, zoning regulations and licensing requirements. The official plan policies permit second units within detached, semi-detached and townhouse dwellings, where appropriate. The Zoning By-law is available here.
As of January 2, 2014 a licence is required for a Second Unit to be legal (see City By-law204-13) .
