Why CNB in Etobicoke

One crew. Fixed price.
Permits sorted.

Etobicoke fell under City of Toronto in 1998. Your permit goes to 2 Civic Centre Court — not a separate municipality. Processing time: 6–10 weeks. Kipling and Islington subway stations plus the Lakeshore GO line put legal suites here in front of strong transit-dependent rental demand. CNB submits the application, tracks status, and schedules all inspections.

FAQ · Etobicoke

Questions about basement
renovation in Etobicoke.

Do I need a permit for a basement in Etobicoke?

Yes. Etobicoke is City of Toronto — all basement finishing, suites and structural work require a Building Permit. CNB submits the application, BCin drawings and handles every inspection. There is no extra charge for this.

How much does a basement renovation cost in Etobicoke?

A standard finish runs $35,000 – $55,000. A legal second suite with separate entrance is typically $65,000 – $95,000. Underpinning adds $75–145/sqft. We give you a written price before we start.

How long does it take?

Build phase: 8–12 weeks. Permit issuance by the City of Toronto: 6–10 weeks. Factor 4–5 months from first call to occupancy. We give you a firm schedule upfront.

Can I add a second suite in an Etobicoke bungalow?

Yes — the province amended the Planning Act to allow secondary suites as-of-right across Ontario. We verify zoning, file all permits, and deliver a rent-ready unit. Etobicoke suites rent for $1,800–2,400/month in 2026.

What is underpinning and do I need it?

Underpinning lowers the basement floor to achieve the OBC-required 1.95 m ceiling height. About 35% of Etobicoke bungalows need it. We assess on site and quote separately.
