Rohnert Park, CA Parking Rules: Curb Color Rules (2026)

Curb-color meanings are fixed by California Vehicle Code Sec. 21458, which Sonoma County applies on its roads: red means no stopping, standing, or parking (a bus may stop in a red zone signed as a bus loading zone); yellow means stopping only to load or unload passengers or freight for the time set by local ordinance; white means stopping only to load or unload passengers (or deposit mail in an adjacent mailbox); green means time-limited parking specified by local ordinance; and blue means parking limited exclusively to vehicles displaying disabled-person or disabled-veteran plates or placards. Under Sonoma County Code Sec. 18-3.2(c), the Public Works Director is authorized to maintain, by signs or paint on the curb surface, all no-stopping zones, no-parking areas, and restricted-parking areas; where legible curb markings or signs are in place, no driver may stop, stand, or park in violation of them. Official curb markings on County roads are installed and maintained by Sonoma Public Infrastructure - private parties may not paint regulatory curb colors. Separately, any individual, organization, or company that wishes to solicit and perform house-numbering curb painting (the white address-number curb service) within an unincorporated area must first obtain an encroachment permit from the County's Department of Public Works / Sonoma Public Infrastructure.
