A legal basement suite is the highest-payback square footage a Vancouver house can hold — but 'legal' is doing all the work in that sentence. Here's what legal means, what it costs, and what it returns.
What makes a suite legal
- Its own exit — a code-compliant separate entrance and escape windows in bedrooms.
- Ceiling height — generally 2.0 m minimum over required areas (municipality-specific).
- Fire separation — rated assemblies between suite and main home, interconnected smoke alarms.
- Ventilation & heat — independent control, proper bathroom and kitchen exhaust.
- Registration — permits, inspections and, in most municipalities, a suite registration.
The cost of getting there
The return
At $2,200/mo, a suite grosses $26,400 a year — enough to carry roughly $350k of mortgage at 2026 rates. Appraisers value legal suites on income; unauthorized ones get valued at zero and can void insurance claims. The legalization premium is the cheapest insurance policy in housing.
