Secondary Suite Legalization Across Lower Mainland and Fraser Valley: City-by-City Guide (2025)

Why Secondary Suite Legalization Matters in Lower Mainland and Fraser Valley

Lower Mainland and Fraser Valley has one of the most expensive housing markets in North America. For homeowners, a legal secondary suite is one of the most powerful financial tools available.

Despite the financial benefits, thousands of Lower Mainland and Fraser Valley homeowners have unauthorized suites. Some were built without permits. Others were built under older codes that no longer meet current requirements. Legalizing these suites is almost always worth the investment.
