Get My Free Feasibility CheckHow much does a legal basement conversion cost in the GTA?
Most legal basement conversions in the GTA start around $35,000 and up.
Scope, existing conditions, and finish level all affect cost. The right number comes from a site-specific quote — not a generic estimate.
How long does a legal basement conversion take?
Most projects take 8 to 14 weeks from permit approval to final sign-off.
B&Y provides a fixed timeline before work starts — so you plan around a real date, not a guess.
What makes a basement legally rentable in Ontario?
A legal suite in Ontario requires a building permit, minimum ceiling height (1.95m), egress windows in sleeping areas, fire separation between floors, proper ventilation, and electrical compliance.
Zoning rules vary by city — we confirm all of this during your feasibility check.
Does B&Y handle permits, or is that my responsibility?
We handle everything — drawings, city submissions, and inspection scheduling.
Work doesn't start until approvals are in hand. You don't chase a single form.
Will the suite pass inspection on the first try?
We build to code at every stage — not just the final inspection.
Inspections are scheduled throughout the build so issues are resolved before they become problems. The goal is a clean pass and a rental-ready suite from day one.

That's exactly what the free feasibility check is for.
We review your zoning, ceiling height, and site conditions first. If it can't be done legally, we tell you upfront — before you spend anything.
