What are Second and Third Units?
Second and third units are self-contained residential spaces within a primary home. They are permitted in:
- Detached homes
- Semi-detached homes
- Townhouses
These units can be located anywhere in the home as long as zoning requirements are followed. Adding extra units can provide more affordable housing options and increase property value.
What is a Garden Suite?
A garden suite is a separate residential unit located on the same property as a main home. It must:
- Be in the rear or interior side yard
- Be detached from the main house (or attached to a detached garage)
- Be secondary to a detached, semi-detached, or townhouse dwelling
Important: The application process for a garden suite starts with the
Planning Division, not the Building Division. After planning approval, you must still apply for a building permit.
Registration Requirement and Allowable Units
All second units, third units, and garden suites must be
registered with the City of Brampton to be considered legal.
Properties are allowed a maximum of
three units, including the main dwelling.
Options include:
-
Option 1: Main dwelling + one second unit (inside) + one garden suite (separate building)
-
Option 2: Main dwelling + two internal units (second and third units)
If you already have a registered second unit, you may apply to add a third unit. You can also apply for both a second and third unit at the same time using one set of drawings.
