If you install heat, ducts or venting on Brampton basement apartments, the City's two-unit drawings and inspection lists spell out what they expect to see. This page is for HVAC contractors, not a substitute for the building code.
Brampton's Two-Unit Dwelling Registration & Permit Application Guide says proposed floor layouts must show the location of all heating supply outlets and return air grills, exhaust air intakes, and the location of duct-type smoke detectors within the air-handling system that serves the entire building. Fire separations and plumbing fixtures are on the same drawing list.

A legal second unit needs heat and return air in that suite, and shared systems need the duct smoke detector called out on the drawings. That is HVAC work tied to the building permit, which is the signal we email.
