How long does a basement renovation take in Toronto?

Most basement renovations we complete run 6–12 weeks depending on scope. A straightforward finish with open layout and no new bathroom often lands in six to eight weeks. A full suite with bathroom, kitchenette, and permit inspections typically runs ten to fourteen weeks. You receive a written timeline before work starts.

What does a basement renovation cost in the GTA?

Basement renovation costs in the Greater Toronto Area commonly range from about $45–$75 per square foot for a basic finish with quality materials to $100+ per square foot for a legal secondary suite with bathroom, kitchen, and upgraded finishes. Drivers include new plumbing stacks, egress, ceiling height fixes, and finish grade. We provide a fixed-price written quote after a site visit.

Do basement renovations need a permit in Toronto?

Often yes. New or moved plumbing, additional circuits, structural changes, new dwelling units, and egress window installs typically require a permit in Toronto and most GTA municipalities. We flag permit needs during the scope walk and include compliant work in the quote.

Can we live upstairs during a basement renovation?

Yes — most clients stay in the home. We isolate dust, protect main-floor traffic paths, and schedule noisy work in predictable blocks. Stairs and mechanical access stay usable unless a short shutdown is planned with notice.

Do you offer basement renovations in Mississauga, Vaughan, and North York?

Yes. We perform basement renovations across Toronto and the GTA including Mississauga, Vaughan, North York, Etobicoke, Richmond Hill, and Markham. Travel and service area are included in our quotes — no surprise mileage fees by municipality.

The Adept approach

One crew.
One quote.
Code-smart basements.

Basement renovations go wrong when mechanicals, insulation, and permits are sequenced as afterthoughts. We run the full scope — rough-in through finishes — with one accountable team and a fixed price agreed before we open walls.

Written scope, allowances, and timeline before you commit
Licensed plumbing and electrical partners coordinated in-house
Dust control and daily clean-up — built for families living upstairs

How it works

Your basement renovation, step by step

Predictable milestones, inspection-ready sequencing, and one point of contact from start to finish.

Site visit & code check

We measure ceiling height, utilities, and existing structure, then walk through layout, egress, and bathroom or bar options so basement renovation cost drivers are clear early.

Fixed-price quote

Within 48 hours you receive a written basement renovation price and schedule — allowances and permit assumptions spelled out, not buried in fine print.

Rough-in & inspections

Framing, mechanicals, and insulation sequenced for inspection milestones where required — debris managed and stairs kept safe if you are living upstairs.

Drywall & finishes

Board, mud, prime, then floors, trim, cabinets, and fixtures — one accountable crew through paint and hardware.

Final walkthrough

We test outlets, valves, and doors with you, address punch items, and leave the basement renovation move-in ready.

“Responsible team, no need to babysit them. In fact they delivered more than I had agreed to, without increasing the price.

I definitely recommend them!”
