ScaleBig Construction is based in Mississauga and builds legal basement apartments throughout the city — from Port Credit and Lorne Park to Streetsville, Erin Mills, Meadowvale, and Cooksville. Mississauga's Additional Residential Unit bylaw makes legal second suites one of the strongest ROI plays for local homeowners, and we handle the entire process so you don't deal with the city directly.
Every Mississauga build is permitted, ESA-inspected, and signed off — protecting your property value, your insurance, and any future sale. With a two-bedroom legal suite in Mississauga renting for $2,000+/month, most clients see their investment paying for itself in well under a decade.
