Legal Basement Apartments in Mississauga, Oakville & the GTA
Turn your basement into a legal rental unit — designed by a licensed Professional Engineer, permitted and built by one team. Drawings, building permit, underpinning and construction, all handled for you.
What Makes a Basement Apartment Legal?
Fire Separation & Alarms
Fire-rated separation between the two units, plus working smoke and carbon monoxide alarms.
Safe Exits
A separate entrance and egress windows, so everyone in both units can get out safely.
Ceiling Height & Natural Light
Enough headroom and window area to meet the Ontario Building Code for a second unit.
Heating, Ventilation & Plumbing
Proper heating, fresh-air ventilation and plumbing for a comfortable, healthy unit.
Parking & Zoning
Your property must meet your city's parking and zoning rules. We check all of these items at the first visit, before you spend money on drawings.
Low Ceiling? We Can Fix That.
Many older basements are too low for a legal unit. EXA Takaful Canada specializes in underpinning: lowering the basement floor safely, designed and supervised by our engineer. We design the underpinning and the apartment together, under one permit.
