What is the process for getting a secondary suite permit in Vancouver?

Getting a secondary suite permit in Vancouver involves submitting a building permit application through the city's online portal or in-person, with the process typically taking 4-8 weeks for straightforward projects. Secondary suites are legal in all single-family zones in Vancouver, and the city has streamlined the approval process significantly over the past few years.

The building permit application is your main requirement - there's no separate "secondary suite permit." You'll need to submit detailed drawings showing the proposed suite layout, including separate entrance, egress windows, fire separation details, and mechanical systems. The plans must demonstrate compliance with the BC Building Code (BCBC 2024), including proper ceiling heights (minimum 6'6" in basements), emergency egress windows in bedrooms, and fire-rated separation between units.

Key technical requirements include interconnected smoke alarms throughout both units, separate electrical panels or subpanels, adequate parking (though this is often waived), and proper sound insulation between floors. The suite must have its own kitchen, bathroom, and separate entrance - either exterior or through a common hallway with a locking door. Basement suites need proper drainage, waterproofing, and often require upgrading the main electrical service to handle the additional load.

These factors make this process more straightforward than many municipalities. The city actively encourages secondary suites as part of its housing strategy, and you don't need rezoning or development permits for most situations. However, if your home is heritage-designated or in certain character areas, additional approvals may be required. The city also offers a suite legalization program for existing unpermitted suites, which can be more cost-effective than full compliance upgrades.

Professional requirements vary by scope of work. Electrical work must be done by a licensed electrician and inspected by Technical Safety BC (TSBC). Plumbing rough-in requires a licensed plumber. Structural changes need an engineer's stamp. While homeowners can do some finishing work themselves, most suite conversions require multiple trades and proper coordination.

Costs and timeline in Vancouver typically range from $40,000-$80,000 for a basic basement suite conversion, including permits, professional fees, and construction. Permits alone cost $1,500-$4,000 depending on project complexity. The city's building department processes most secondary suite permits within 4-8 weeks, though complex projects requiring structural changes can take longer.
