Understanding Brampton’s Additional Residential Units (ARUs) Policies and Bill 23 Conformity

Brampton, like many growing cities, is adapting its housing policies to support diverse and inclusive housing needs. Additional Residential Units (ARUs), also known as accessory residential units, accessory apartments, granny flats, in-law suites, laneway suites, or coach houses, are self-contained living spaces with their own cooking, sanitary, and sleeping facilities. These units can be part of a single detached, semi-detached, or townhouse dwelling or located in an ancillary building like a garden suite. This initiative aligns with Housing Brampton’s goals of providing age-friendly and inclusive housing that is both affordable and accessible.

Bill 23 Conformity: The More Homes Built Faster Act, 2022

In response to Bill 23, known as the More Homes Built Faster Act, 2022, the City of Brampton undertook a comprehensive Policy Review to update ARU policies in the Official Plan and Zoning By-law. This Act, which received Royal Assent on November 28, 2022, aims to accelerate the construction of homes to meet the growing demand. Brampton adopted the necessary amendments on May 3, 2023, ensuring their ARU policies are in effect and compliant with Bill 23.
