Solano County, CA Parking Rules: EV Charging (2026)

Unlike many cities, the unincorporated Solano County Zoning Ordinance does not contain a dedicated electric-vehicle charging or EV-ready parking standard. Section 28.94, which governs parking requirements, addresses the minimum number, size (9 by 18 feet for residential spaces), surfacing, lighting, and accessible-parking design of parking areas, but does not require EV charging spaces or reserve EV-only stalls. As a result, installing an EV charger on a residential or commercial property is treated primarily as an electrical/building matter: California requires expedited permitting for EV charging stations under state law, and the County issues electrical permits through its Building and Safety Division. Accessible parking for the disabled must continue to be provided in accordance with the applicable Building Codes (Section 28.94(K)), and any new EV parking layout must still satisfy the parking-area surfacing, marking, and access standards of Section 28.94. Because the County has not adopted EV-specific signage or enforcement rules, towing or citation for misusing a posted EV-only space on private property is a matter of the property owner's posting and state law rather than a County ordinance. Confirm current permit requirements with the County's Building and Safety Division before installing a charger.
