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

Glenn County treats curb markings as a formal traffic-control device tied to its parking ordinance. Section 11.08.005 (Prohibited Or Restricted Parking) provides that where the Board of Supervisors restricts parking on county roadways by resolution, the restriction is not effective until 'appropriate signs giving notice that parking is prohibited or restricted are erected,' and adds that 'in lieu of signs, curb markings in accordance with section 21458 of the Vehicle Code of the State of California may be used.' The section makes it 'the duty of the County Road Commissioner to erect and maintain appropriate signs or install proper curb markings giving notice of the areas of prohibited or restricted parking.' California Vehicle Code Section 21458 standardizes curb-paint colors statewide - red (no stopping, standing or parking), yellow (loading), white (loading/unloading of passengers), green (time-limited parking) and blue (disabled parking). Because curb colors carry these legal meanings and are installed by the county, a property owner painting their own curb red or otherwise is not authorized to create an enforceable parking restriction. Within designated county parking lots, Section 11.08.007 similarly requires that restricted areas be 'clearly marked as to the restrictions imposed' with posted signs at every entrance and exit. Residents wanting a curb marked or a restriction added should contact the Glenn County Public Works Agency rather than painting a curb themselves.
