How does BC's annual rent cap work?

Direct answer

BC's annual maximum rent increase for existing tenancies under the Residential Tenancy Act (RTA) is set each year by the Residential Tenancy Branch and ties to inflation. For 2026 the maximum allowable rent increase is published annually by the BC government — verify the exact current-year figure against the live RTB rent-increase page before relying on it. A landlord can only increase rent ONCE in any 12-month period, and must give 3 full months' written notice using RTB Form RTB-7. The cap applies to fixed-term and month-to-month tenancies alike. The cap does NOT apply to vacancy resets — when a tenant moves out, the landlord can re-list at any market rent for the new tenancy. The cap also does NOT apply to non-RTA tenancies (commercial, hotels, transient accommodation, supportive housing of certain types). Practitioner truth: the rent cap interacts with vacancy decontrol to create a "long-tenant discount" — properties with sitting tenants of 5+ years often rent below market by 30-50%, which is reflected in lower investor cap rates. New investors should always model both current-rent and market-rent scenarios. The RTA was amended via Bill 14 (2024) to tighten "personal use" eviction rules, making it harder to convert below-market tenancies — covered in a separate Q&A.
