Changes to the ARU Registration and Permit Requirements
As of March 3, 2025, you will no longer be required to email your Electrical Safety Authority (ESA) certificate to Twounit.zoning@brampton.ca to finalize the registration process for your Additional Residential Unit (ARU). This will simplify the registration process for customers as the final registration certificate will be issued at the same time as occupancy is granted for an ARU permit. The City will be proactively notifying the Electrical Safety Authority on a regular basis about all new ARUs in Brampton.
Property Surveys
When submitting a building permit application, the legal survey must be legible and include the signature and information of the surveyor who prepared the document. During permit submission, the document will be reviewed and determined if acceptable. If not acceptable, you will need to find an alternative method of locating a survey. Please note: the City of Brampton does not maintain a record of surveys for all properties.
Is the property on Conservation Authority Lands?
As of April 1st, 2024, the Conservation Authority Act was amended requiring approval by the
Credit Valley Conservation
(CVC) or the
Toronto and Region Conservation Authority (TRCA) when constructing an additional residential unit within the lands regulated by the conservation authorities. Your permit will not be allowed to proceed if approval is not granted by the associated conservation authority. To contact the conservation authorities, click the links above.
NEW: Inspection Recall Fee for ARU Units
Effective July 21, 2025, a new Inspection Recall Fee applies to Additional Residential Unit (ARU) permits. ARU permits include Two-Unit and Three-Unit Dwellings, as well as Garden Suites.
- If an inspection does not pass on two separate occasions, a fee will be charged for any following inspections.
