Solano County, CA Parking Rules: Curb Color Rules (2026)

Solano County does not have its own curb-color ordinance for the unincorporated area; the legal meaning of painted curbs comes from California Vehicle Code Section 21458. Under that section, when local authorities mark curbs the colors mean: red, no stopping, standing, or parking (except a bus at a marked bus zone); yellow, stopping only to load or unload passengers or freight for the time specified by local ordinance; white, stopping only to load or unload passengers, or to deposit mail in an adjacent mailbox, for the specified time; green, time-limited parking specified by local ordinance; and blue, parking limited exclusively to disabled persons and disabled veterans. These restrictions apply during the days and hours prescribed by any local ordinance. Because the unincorporated County generally relies on state law rather than running a city-style curb-marking program, residents should not paint or re-paint public curbs themselves; private painting of curbs in the public right-of-way can constitute an unauthorized encroachment regulated under Chapter 24, which requires a permit from the Director of Transportation for objects placed in, under, or over a County road. On private property, the design and construction of curb openings and driveway approaches must conform to Section 28.94(D) and the Director of Transportation's requirements. For any curb marking on a County road, contact Public Works/Transportation rather than painting it yourself.
