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.
Unincorporated Solano County has not adopted a local just-cause eviction ordinance. Tenants in the unincorporated county are protected by the California statewide Tenant Protection Act of 2019 (AB 1482, codified at Cal. Civil Code Sections 1946.2 and 1947.12). AB 1482 requires "just cause" to terminate tenancies after a tenant has continuously occupied a dwelling for 12 months (or 24 months if any additional adult tenant joined later). Just cause is split into at-fault grounds (e.g., nonpayment, lease breach, nuisance) and no-fault grounds (owner move-in, withdrawal from rental market, government order, substantial remodel), with relocation assistance equal to one month of rent required for no-fault terminations. Single-family homes and condos owned by individuals (not corporations or REITs) are exempt if the landlord delivers the statutory exemption notice. Three-day pay-or-quit notices follow Cal. Code of Civil Procedure Section 1161, and self-help evictions are barred by Cal. Civil Code Section 789.3.
