Yuba City, CA Parking Rules: Curb Color Rules (2026)

In unincorporated Sutter County, curb markings carry the same legal meaning as defined by the State and are installed by the County rather than by private parties. Section 1120-100 of the Traffic Code authorizes the Board of Supervisors, under California Vehicle Code Section 22507, to prohibit or restrict parking on portions of County roadways by resolution; such restrictions take effect only after appropriate signs are erected, and in lieu of signs the County may use curb markings in accordance with California Vehicle Code Section 21458. The section makes it the duty of the County Road Commissioner to erect and maintain signs or install proper curb markings giving notice of prohibited or restricted parking. Section 1120-105 applies the same approach to parking on County-owned property: the General Services Director is delegated authority to restrict parking and to erect signs or install proper curb markings giving notice of prohibited or restricted parking, including notice that vehicles parked in violation are subject to removal under Vehicle Code Section 22651(n). Curb markings, like signs, are the trigger that makes a Section 1120-100 or 1120-105 restriction enforceable, and violations carry a 25-dollar civil parking penalty under Section 1120-110. The published code does not authorize private property owners or residents to paint public curbs themselves; California Vehicle Code Section 21458 governs the meaning of red, yellow, white, green, and blue curb colors statewide. Painting or altering official curb markings without authority would not create an enforceable restriction.
