Basement Finishing in Oakville & Burlington
Turn an unfinished basement into the best room in your house — a family room, home gym, office, or guest space. Design and build under one roof, permits handled when needed.
The short answer
Finishing a basement in Oakville or Burlington typically costs $35,000–$60,000+ depending on the size of the space, the number of rooms, and your finishes. Most projects take 3–6+ weeks. 707 Reno handles the whole job — design, demolition, framing, electrical, and finishes — with permits taken care of when your project needs them.
01What does it cost to finish a basement?
A finished basement in the Oakville and Burlington area generally runs $35,000 to $60,000 or more. The range is wide because no two basements are the same — a large, open basement with a bathroom and a wet bar costs far more than a single open rec room. Here’s what moves the number:
| What drives the price | Impact |
|---|---|
| Size & number of rooms | High |
| Adding a bathroom | High |
| Existing condition (moisture, ceiling height, demo needed) | Medium–High |
| Plumbing & electrical rough-ins | Medium |
| Flooring, trim, and finish level | Medium |
| Wet bar, built-ins, or feature walls | Optional add-ons |
These are starting ranges. A free in-person assessment gets you a real number for your specific basement.
02What’s the difference between finishing and a legal basement apartment?
This is the most important question to sort out early, because it changes the scope, the cost, and whether you need a permit.
Finishing a basement means turning it into livable space for your own household — a family room, home theatre, gym, office, or play area. It’s part of your home, not a separate unit.
A legal basement apartment (a secondary suite) is a self-contained rental unit with its own kitchen, bathroom, and entrance, built to specific Ontario Building Code requirements and registered with your municipality. It costs more and always requires permits.
03Do you need a permit to finish a basement?
Sometimes yes, sometimes no — and it depends on the work, not just the room. Simple finishing (framing, drywall, flooring, paint) often doesn’t require a permit. But the moment you add or move plumbing, alter electrical beyond basic work, add a bathroom, or change the structure, a permit is usually required. We assess this up front and handle the permit and drawings when your project needs them, so you’re never the one guessing.
