Secondary Suites have their own kitchen and living area and may share internal access with the main dwelling unit, but have their own separate external access door. It can occupy up to *40% of the square footage of the home. Some common space may be shared with the primary residence (example: laundry room). *There are a few special cases in dense areas like Burnaby UniverCity area where zoning allows secondary suites within apartments.
