What are the new BC provincial rules for secondary suites that override municipal bylaws?

The BC government has not enacted provincial rules that override municipal bylaws for secondary suites. Secondary suite regulations remain under municipal jurisdiction, meaning each city and district in Metro Vancouver sets its own rules for legal secondary suites.

However, there have been significant provincial housing policy changes that indirectly affect secondary suites. The Housing Supply Act gives the province authority to override certain municipal zoning decisions, and there's ongoing discussion about provincial standards for secondary suites, but as of early 2025, no blanket provincial override exists.

Municipal Authority Remains Key

Each Metro Vancouver municipality continues to regulate secondary suites independently. For example, the City of Vancouver requires secondary suites to be registered, have separate entrances, meet fire separation requirements, and include proper egress windows. Surrey has different rules, as does Burnaby, Richmond, and other municipalities. Some municipalities still prohibit secondary suites entirely in certain zones, while others have streamlined approval processes.

The BC Building Code (BCBC 2024) does establish minimum safety standards for secondary suites — including fire separation, smoke alarms, ceiling heights, and egress requirements — but these are baseline safety requirements, not zoning permissions. Municipalities can add stricter requirements but cannot go below BCBC minimums.

Recent Provincial Housing Initiatives

The province has focused more on multiplex housing through legislation like the Housing Supply Act, which can override municipal zoning to allow duplexes, triplexes, and fourplexes. Vancouver proactively adopted multiplex zoning (R1-1 zone allowing 3-6 units) to avoid provincial override. The province has also introduced Small-Scale Multi-Unit Housing (SSMUH) requirements for some municipalities.

What This Means for Homeowners

You still need to check with your specific municipality for secondary suite rules. In Vancouver, call 311 or visit vancouver.ca. For other municipalities, contact their planning departments directly. If you're planning a secondary suite, you'll need a building permit, and the suite must meet both BCBC safety standards and local zoning requirements.

The regulatory landscape is evolving rapidly, so verify current rules with your local building department before starting any secondary suite project.
