Second Units


Registration for second units began on June 22, 2015.

Second Units are now permitted on detached, semi-detached, and townhouse dwellings, subject to zoning requirements and restrictions. 

Only those units that have been registered with the City are considered legal. 

Following the first year of the registration program, staff identified minor changes that could improve the registration process. 

A public meeting was held on February 13, 2017, to present minor revisions to the second units zoning by-law and registration program.

Second Units

On April 22, 2015, City Council approved new policies permitting second units in the City of Brampton. Second units are now permitted in detached, semi-detached and townhouse dwellings, subject to zoning requirements.
Under the new policies:
  • Only one second unit is permitted per house.
  • In a bungalow, the second unit can be up to 75 per cent of the primary unit’s gross floor area (GFA). For all other houses, the second unit can be up to 45 per cent of the primary unit’s GFA.
  • There must be one parking space for the second unit, in addition to the required parking for the primary unit.
  • There must be a 1.2 metre clear path of travel to a door in the side or rear yard that provides access to a second unit.

Second units offer Brampton residents another option for safe, affordable housing, but in order to be legal, they must be registered with the City of Brampton.

Before registration is approved, units must be inspected by the City to ensure they comply with the Ontario Building Code and/or Fire Code; approval from the Electrical Safety Authority is also required. Units must also meet all Zoning and Property Standards regulations.
