Secondary Suites FAQ

A secondary suite is a self-contained unit within a house that has its own kitchen, bathroom facilities and a separate entrance.

Secondary suites are intended to increase the number of affordable housing options in the City of Vaughan. The Strong Communities through Affordable Housing Act, 2011 amended the Planning Act to require municipalities to authorize secondary suites in their Official Plans and Zoning By-laws.

Secondary suites can be a viable housing option that meets the needs of a variety of people including singles, students, seniors, extended family members and people on fixed incomes, provided they are constructed in compliance with all the applicable regulations.

Before homeowners decide to proceed with renovating their homes to incorporate a secondary suite, they should visit Vaughan’s Building Standards department to discuss their plan and obtain the necessary information regarding zoning, fire code and building permit requirements. All applications must comply with Vaughan’s Zoning By-law, Ontario Building Code and Ontario Fire Code.

Some of the safety requirements associated with secondary suites are:

• Smoke alarms must be located outside all sleeping areas, on every floor level in each unit and should be connected to each other so that when one alarm sounds, they all do.
• Carbon monoxide alarms must be installed outside all sleeping areas in each unit.
• The floor between the secondary suite and the primary dwelling must be constructed as a fire separation. A secondary suite located on the same floor as the primary dwelling must be separated by a vertical fire separation.

A secondary suite may occupy up to 45 per cent of the gross floor area of the main dwelling, but not be less than 35 square metres in floor area.

Policies and licensing of short term rental properties do not fall within the mandate of this program. Short-term rentals are generally understood to be when individuals rent out their residence, or part of their residence, for short periods of time (not more than 29 consecutive nights) for a fee. As of Jan. 1, 2020, short-term rentals are allowed in residential homes in Vaughan – that is the homeowner’s or tenant/lessee’s principal residence – provided that a licence is obtained.
