Solano County, CA Parking Rules: Oversized Vehicle Parking (2026)

There is no County ordinance generally prohibiting oversized recreational or personal vehicles from parking on unincorporated residential streets; on-street limits default to the California Vehicle Code (including the 72-hour rule in Section 6.5-36) and any posted signs under Vehicle Code Section 22507.5 for heavy commercial vehicles. Where the Zoning Ordinance does address large vehicles is for property used for home-based business. Under the Chapter 28 cottage-industry standards, 'large vehicles' are defined by gross vehicle weight rating: a maximum of three large vehicles (generally 14,001 to 26,000 pounds GVWR) plus one trailer per large vehicle may be kept on the property, they may only be stored in an enclosed building, and vehicles exceeding 26,000 pounds GVWR may not be stored on the property in connection with a cottage industry at all. One version of the standard defines large vehicles as those over 14,000 pounds GVWR. For lighter home occupations, no more than one truck of one-ton capacity plus one trailer is permitted on site. Personal oversized vehicles such as motorhomes not tied to a business are not specifically capped by the County zoning code, but remain subject to the abandoned/inoperative vehicle limits of Chapter 6.5 and the 72-hour on-street rule.
