A legal basement apartment is a complete Additional Residential Unit project, not simply a finished room with a kitchen. The property, proposed layout, construction details, inspections and registration all need to align.
A second or third unit must follow the applicable permit and safety requirements and be registered with the City of Brampton. If it will be rented, the separate Residential Rental Licence may also be required before operating.

Do not design a rental apartment as an ordinary finished basement.
If the long-term plan includes a self-contained rental unit, make that intention clear before drawings or construction begin. Retrofitting the wrong design later can add cost and rework.
