California rental market faces new limits and regional price gaps

California is experiencing divergent rental market trends and new regulatory constraints. Under Assembly Bill 1482, the California Tenant Protection Act of 2019, new statewide rent increase limits have taken effect. Landlords are prohibited from increasing rental rates by more than 5% plus inflation, or 10%, whichever is lower, over a 12-month period. This cap remains in effect until July 31, 2027. Specific regional maximum increases vary, with San Francisco at 8.8%, Los Angeles at 8.7%, and San Diego at 8.2%.

Market data for the first half of 2026 indicates a significant price gap between the northern and southern parts of the state. The median rent for a three-bedroom house in Southern California is approximately $3,900 per month, while Northern California averages $3,100. While Northern California has seen a 4% increase in rents—partially driven by artificial intelligence wealth in the Bay Area—Southern California rents have remained flat over the past year.

Exemptions to the rent increase laws include housing built within the last 15 years, owner-occupied duplexes, and single-family homes or condos not owned by corporations, provided tenants receive written notice. Critics of the rent control measures argue that such price controls suppress housing supply, suggesting that increasing competition through new construction is a more effective way to reduce costs.
