Rent control rules in Solano County, CA — also known as rent stabilization or rent cap ordinances — limit annual rent increases and protect tenants from displacement.
Unincorporated Solano County has no local rent control ordinance. Rent increases are governed by the statewide rent cap in the Tenant Protection Act of 2019 (AB 1482), codified at Cal. Civil Code Section 1947.12. AB 1482 caps annual rent increases on covered units at the lesser of 5% plus the regional April-to-April CPI (San Francisco-Oakland-Hayward CPI applies in Solano County) or 10%, measured over any 12-month period. The cap covers most multi-family rentals and corporate-owned single-family homes once the unit has a Certificate of Occupancy more than 15 years old (a rolling exemption). New construction within the prior 15 years, individually-owned single-family homes and condos with proper exemption notice, owner-occupied duplexes, and pre-1995 deed-restricted affordable housing are exempt. Costa-Hawkins (Cal. Civ. Code Sec. 1954.50 et seq.) further preempts local vacancy control. The AB 1482 cap expires January 1, 2030 unless extended.
