Mendocino County, CA Parking Rules: Commercial Vehicle Restrictions (2026)

Under Mendocino County Code Section 15.12.090, no person may stop, park, or leave standing a commercial vehicle, attended or unattended, between the hours of 8:00 p.m. and 6:00 a.m. in a designated residential area if the commercial vehicle has or exceeds an unladen weight rating of 10,000 pounds. The prohibition does not apply to a commercial vehicle making pickups or deliveries of goods to or from a building on the restricted streets, or delivering materials for bona fide repair, alteration, remodeling, or construction of a building for which a building permit has already been obtained. The ordinance applies in named residential areas: in the Hopland area on MacMillan Drive (CR 114-B) and St. Mary's Avenue (CR 114-C), and in the Meadowbrook area south of Ukiah on Meadowbrook Drive (CR 252-E). Outside those designated areas, the County Code does not impose a categorical commercial-vehicle street-parking ban, so the California Vehicle Code and the general 72-hour rule (MCC 15.12.091) apply. On private property, commercial vehicle parking and storage is regulated through the Zoning Code (Title 20). A violation of Section 15.12.090 is an infraction under MCC 15.12.100 and CVC Section 42001(a).
