Vacaville, CA Rental Property Rules: Rental Registration (2026)

Unlike cities such as Sacramento, Oakland, Berkeley, and Los Angeles, Vacaville has not adopted a rental-registration ordinance. There is no city Rental Housing Inspection Program, no annual unit-level registry, no proactive inspection cycle, and no per-unit registration fee in the Vacaville Municipal Code. Landlords renting residential property are required to hold a general business license under Title 5 (Business Taxes, Licenses and Regulations) for the rental activity, with the license-tax calculation set by Chapter 5.12 and exemptions in Chapter 5.16. They are also subject to the California Civil Code landlord-tenant framework: Section 1941 et seq. (warranty of habitability), Section 1942.4 (rent withholding for substantial habitability defects), Section 1950.5 (security deposits), Sections 1946.2 and 1947.12 (just cause and rent cap under AB 1482), and Section 789.3 (anti-self-help). Habitability and code-enforcement complaints at Vacaville rental properties are handled by the Code Enforcement Division of the Fire Department (Community Risk Reduction) under Chapter 8.10 (Abatement of Public Nuisance) and Chapter 1.28 (Abatement of City Ordinance Violations), generally on a complaint-driven rather than proactive basis. Units leased through the Solano County Housing Authority's Housing Choice Voucher (Section 8) program are subject to HUD Housing Quality Standards inspections by the Housing Authority before a Housing Assistance Payments (HAP) contract is signed and annually thereafter; that program is administered by Vacaville Housing and Community Services in coordination with the Solano County Housing Authority. Landlords are independently required by California Health and Safety Code Section 13113.7 to ensure operative smoke alarms, and by Section 13113.8 to install carbon monoxide alarms in dwellings with fuel-burning appliances or attached garages.
