Legal Basement Apartment in Pickering

A legal second suite turns a basement into a self-contained rental or family apartment. The difference between legal and not is the permit, the fire safety and the inspections. In Pickering, most of the housing is 1960s to 1990s subdivisions, with older streets near the lake.

Fire separation between units, a safe exit, ceiling height, window size, smoke and carbon monoxide alarms, and properly inspected electrical work.
