Frequently Asked Questions — Basement Renovation in Innisfil

What makes a basement apartment legal in Ontario?›
A legal second suite in Ontario requires a building permit, minimum ceiling height (usually 6'5"), egress window from each bedroom, proper fire separation from the main unit, a working kitchen and bathroom, and compliance with local zoning. We handle all of these.
How much does a legal basement apartment cost?›
A full legal basement conversion typically runs $60,000–$120,000 in the GTA depending on existing conditions, ceiling height requirements and finishes. Underpinning adds cost but may be necessary. We provide a detailed quote after a free site visit.
What is underpinning and do I need it?›
Underpinning lowers the basement floor to increase ceiling height. Ontario code requires at least 6'5" in a legal suite — if your existing basement is shorter, underpinning is the solution. We include engineering and permits in the price.
Do I need a permit to finish my basement?›
Yes for most work — adding rooms, egress windows, electrical and plumbing all require permits. Finishing work done without permits can cause problems when you sell. We pull all required permits as part of our service.
How long does a basement renovation take?›
A basic basement finishing takes 4–8 weeks. A legal basement suite takes 3–6 months when underpinning is involved. Permit timelines vary by municipality. We include a milestone schedule in your contract.
How quickly can you get to my home?›
For most bookings we can arrange a same-day or next-day visit. Emergency calls are dispatched as a priority and we aim to arrive within a few hours.
Is there a service-call or inspection fee?›
We offer a free estimate — there is no charge to come out, diagnose the issue and provide a written quote. You decide whether to proceed before any work begins.
