Frequently Asked Questions — Basement Renovation in Mississauga

What makes a basement apartment legal in Ontario?›
Ontario's Additional Residential Units rules require permits, fire-code separation, egress windows, minimum ceiling height and zoning compliance. We guide you through every requirement and manage the permit process.
How much does a legal basement apartment cost?›
Cost depends on the existing basement, whether underpinning is needed, finishes selected and permit fees. We give you an itemized written quote after the free assessment — most legal suites in the GTA pay for themselves within 3–5 years in rental income.
What is underpinning and do I need it?›
If your basement ceiling is under 7 feet, underpinning creates usable, comfortable living space and meets code minimums for a legal suite. It's a significant but often worthwhile investment. We assess and quote during the free visit.
Do I need a permit to finish my basement?›
Yes. Framing, electrical, plumbing and egress windows need building permits in Ontario. We apply for every required permit and manage all city inspections so your work is properly documented.
How long does a basement renovation take?›
Basement finishing: 4–8 weeks. Legal suite with underpinning: 3–6 months. Permit approval adds 2–6 weeks depending on the city. We give you a realistic schedule and update you at every stage.
How quickly can you get to my home?›
Same-day availability is our goal. Emergencies get immediate priority dispatch; for non-urgent work we typically book within 24 hours.
Is there a service-call or inspection fee?›
No service-call fee. Our technician visits, assesses the problem and gives you an upfront price at no cost. Work starts only once you approve.
