Yes. A residential addition in Brampton requires a building permit because it changes the building area, structure, foundation, roof, and exterior envelope. The design must be reviewed for the Ontario Building Code, property-specific zoning, and any applicable mature-neighbourhood, heritage, or conservation requirements.

A home addition should begin with the property rather than a preferred floor plan. The legal survey, existing setbacks, lot coverage, building height, grading, easements, and the connection to the existing structure can all affect what can be designed and submitted.
Brampton’s residential addition package calls for a legal property survey, site plan, architectural plans, elevations, and sections. Structural, HVAC, energy-efficiency, grading, drainage, or other consultant information may also be required depending on the scope.
An addition of 50 square metres or more to a detached or semi-detached home in a mature-neighbourhood area may be subject to site-plan review. Heritage and conservation-authority requirements should also be identified early where they apply.
Share the property address, survey, existing-house information, and proposed addition. Permit Works can review the likely zoning, drawing, consultant, and Brampton submission requirements before design proceeds.
