Legal Basement Apartment in
Toronto & the GTA

What Is a Legal Basement Apartment Conversion?

A legal basement apartment is a self-contained secondary dwelling unit within your home’s existing foundation — fully permitted, independently accessed, and compliant with all Ontario Building Code requirements. Unlike illegal basement suites, a legal conversion protects your insurance coverage, mortgage standing, and exposes you to zero municipal fine risk.

Most legal basement apartment conversions take 10–16 weeks from permit approval to occupancy. The permit approval process itself (handled by us) typically takes 4–8 weeks with the City of Toronto. We provide a firm project schedule during your free feasibility consultation.

A full turnkey legal basement conversion in the GTA typically ranges from $85,000 to $145,000 depending on size, existing conditions, and finish level. This includes all permits, engineering, structural work, mechanical systems, and finishes. We provide a full itemized quote after your property audit — no hidden costs.

No — if your existing ceiling height is below the OBC minimum of 1,950mm (6'5"), we offer basement underpinning and foundation lowering as an integrated service. We assess underpinning feasibility as part of your free site audit. Many Toronto homes built before 1970 require this and it's a routine part of our work.

Yes — we offer full retroactive legalization and retrofit services. We audit your existing suite, identify every OBC code gap, and bring the unit into full compliance. This is often more cost-effective than a ground-up conversion. We handle all permit submissions, required upgrades, and final inspections.
