Additional Residential Units

Page Banner

The City of Brampton has initiated a Policy Review to implement Additional Residential Unit (ARU) policies in the Official Plan and Zoning By-law to conform to Bill 108 More Homes, More Choice Act, 2019 and the recommendations of Housing Brampton, the City’s affordable housing strategy.

The Policy Review will implement permissions for additional residential units within an accessory structure on the same lot as a single-detached house, semi-detached house, or townhouse. The Planning Act definition for “additional residential units” includes second units and the detached ARUs described here. For the purposes of ease of administration, “second units” will continue to remain and “additional residential units” will be introduced as detached residential units (ARU). The purpose of these policies is aimed to reduce zoning barriers to the creation of additional residential units and support the supply and range of affordable rental accommodations in the City.

Additional Residential Units (ARU), also known as additional dwelling units or accessory residential units, accessory apartment, granny flats, in-law suites, laneway suites, and/or coach houses, are self-contained residential units with separate kitchen, bathroom and sleeping facilities within accessory building or structures located on the same lot as the principal dwelling, with a separate access. This project is an early deliverable of the Housing Brampton, which aims to support the provision of age friendly and inclusive housing that is affordable and accessible to all.​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​
