Basement Finishing
in Toronto.
A basement is the cheapest square footage you'll ever add — the foundation, roof, and walls are already paid for. We finish them dry, warm, and legal: proper moisture control before the drywall goes up, egress and fire separation if it's becoming a suite, and underpinning when the ceiling is too low to live under. Serving homeowners across Toronto — including The Annex, Leslieville, Roncesvalles, High Park, Riverdale.
Typical investment in Toronto: $45K–$90K finished; $150K+ with underpinning or a legal suite

Permits in Toronto
We handle the municipal paperwork.
Toronto building permits are issued by the city's Toronto Building division. Most kitchen and bathroom renos require an electrical permit plus a building permit if walls move; we file both and schedule the ESA inspection.

Toronto FAQs
Things Toronto homeowners ask.
- Do I need a permit for basement finishing in Toronto?
- Toronto building permits are issued by the city's Toronto Building division. Most kitchen and bathroom renos require an electrical permit plus a building permit if walls move; we file both and schedule the ESA inspection.
- Is my ceiling too low to finish the basement?
- Ontario Building Code wants 6'5" for living space (6'1" under beams). Most pre-1950 Toronto homes sit below that — which is what underpinning or bench footings solve. We measure on the first visit and tell you straight whether you need it or just think you do.
- Can I rent out the finished basement legally?
- Only if it's built as a legal secondary suite: proper egress, 45-minute fire separation, interconnected smoke alarms, and often a separate entrance. We build to that standard and pull the permits — a basement that merely looks finished can't be legally rented and becomes an insurance problem.
- What about moisture? My basement smells damp.
- Then we fix that first. Finishing over a moisture problem buys you mould behind new drywall within two years. We check grading, gutters, and foundation cracks before quoting the finish — sometimes the fix is a $600 downspout extension, sometimes it's interior weeping tile. Either way it happens before the insulation goes in.
