“Turnkey” shows up in almost every renovation ad, and it almost never comes with a definition. Here’s ours. A turnkey basement renovation in Toronto means one team takes your basement from bare concrete to a floor that’s ready to live in, with one contract, one schedule and one fixed price. This guide breaks down what that should include, what it costs per square foot, and what to check before you sign with anyone, including us.
What “Turnkey” Actually Means
The opposite of turnkey is you playing general contractor: finding a framer, an electrician, a plumber, a drywaller and a flooring crew, then keeping five schedules from colliding. Every gap between trades is another week your basement sits half-done, and when something goes wrong, each trade points at the other one.
In a turnkey project, that coordination is the contractor’s job. You approve the design and the price at the start, and the next big decision you make is where the couch goes. Our basement renovation service works exactly this way, and this article is essentially its fine print, spelled out.
What’s Included in a Turnkey Basement Renovation
A real turnkey scope covers six layers. If a quote calls itself turnkey but one of these is missing, ask why.
– Design and a fixed price. You should see the finished basement before it exists. We build a photorealistic 3D design and lock a fixed price, both approved before anyone touches a wall.
– Permits and code. Structural changes and new plumbing need a building permit from the city, and electrical work in Ontario goes through an ESA notification filed by a licensed electrician. A cosmetic refresh often needs neither; a proper renovation usually needs both, and that gets confirmed at the assessment, not discovered mid-build.
– The shell. Demolition and prep, waterproofing and moisture control, insulation, framing.
– The systems. Electrical, plumbing, lighting, soundproofing between floors.
– The finishes. Drywall, flooring, ceiling, trim, paint, and the custom storage that makes a basement actually usable.
– The handover. Cleanup, a final walk-through, and warranty activation. Ours is 5 years on work and materials.
What It Costs: Real Numbers from the GTA
A standard finished basement in the GTA starts around $65 per square foot. That covers framing, insulation, drywall, flooring, lighting and a clean, livable layout. For a typical 700 square foot basement, that’s about $45,500. A bathroom or a kitchenette moves the number up, because plumbing is the expensive part of any renovation.
A legal basement apartment is its own category: from $75 per square foot, with most projects landing between $60,000 and $110,000 all in. The extra cost buys fire separation, code-required egress windows, a full kitchen and a separate entrance, and it pays differently too: suites like these rent for $1,500 to $2,200 a month in the GTA. Our guide to building a legal basement apartment in Ontario walks through the rules step by step.

Turnkey or Managing the Trades Yourself?
On paper, hiring each trade yourself looks cheaper, and sometimes it is, if you have the time, the contacts and the stomach for it. The costs that don’t show up on paper are the gaps: the three weeks between drywall and flooring because the crews’ schedules didn’t line up, the change that one trade makes without telling the next one, the warranty that covers each piece of work but not how the pieces fit together.
Turnkey trades those risks for one number and one responsible party. You pay for project management, and in return the schedule, the budget and the warranty all live in one contract. For most homeowners renovating a basement once, that trade is worth it.
What to Check Before You Sign
Any contractor can write “turnkey” in a quote. Five things tell you whether it’s true:
- A fixed price in writing, with exclusions listed. If the price can move, it’s not fixed.
- A design you approve before construction, not a sketch after demolition.
- Permits named in the contract: who applies, and for what.
- A warranty with a number attached. Ours is 5 years.
- A schedule with an end date, and a way to see progress. We send photo updates every evening.
What a Finished Turnkey Basement Looks Like
The best way to judge a turnkey promise is a delivered project. Our bright family basement in Mississauga went from unused space to a light, open family floor with custom storage built where the family actually needed it. That’s the standard the word “turnkey” is supposed to mean.

Frequently Asked Questions
A standard finished basement starts around $65 per square foot in the GTA, so a 700 square foot space runs about $45,500. A legal basement apartment starts around $75 per square foot, with most projects between $60,000 and $110,000. The exact number depends on plumbing, ceiling height and the condition of the foundation, which is why we quote a fixed price only after a free in-home assessment.
If the project moves structure or adds plumbing, yes, you need a building permit from the city. Electrical work in Ontario requires an ESA notification filed by a licensed electrician. A purely cosmetic refresh, like new flooring and paint, usually doesn’t need a permit. We confirm what your specific project needs during the assessment.
Most turnkey basement projects take two to three weeks. You receive a schedule before we begin and photo updates every evening, and the timeline is backed by our on-time guarantee.
The quote is usually higher, the final cost often isn’t. Self-managed projects tend to grow through gaps between trades, redone work and small decisions made without seeing the whole picture. Turnkey puts the schedule, the budget and the warranty in one contract, so the number you approve is the number you pay.
Yes, if it’s built to code from the start: fire separation, egress windows, ceiling height and a separate entrance all have specific requirements in Ontario. It costs more than a standard finish, and the rent usually justifies it. Start with our legal basement apartment guide to see whether your basement qualifies.
