The 2026 property assessments for about 1,140,000 properties in British Columbia's Lower Mainland reflect market values as of July 1, 2025. Most homeowners can expect assessed value decreases between -10% to 0%, with regional variations. Total assessments in the Lower Mainland dropped from $2.01 trillion to $1.92 trillion, including $24 billion from new developments. Property owners can review assessments online and appeal by February 2 if needed. Assessment changes do not directly determine property taxes.
