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

Commercial vehicle parking in residential areas of unincorporated Merced County is regulated under Section 11.12.040 of the Merced County Code (Title 11, Standing, Stopping and Parking). It is prohibited to park or leave standing on any street, or portion of a street, in a residential district any commercial vehicle, as defined in California Vehicle Code Section 260, having a manufacturer's gross vehicle weight rating of 10,000 pounds or more. This section is adopted pursuant to California Vehicle Code Section 22507.5, which authorizes local authorities to restrict heavy commercial vehicle parking in residential districts. The prohibition does not apply to a commercial vehicle making pickups or deliveries of goods, wares, and merchandise from or to a building or structure on the restricted street, or delivering materials used in the actual and bona fide repair, alteration, remodeling, or construction of a building or structure for which a building permit has previously been obtained. The 10,000-pound GVWR threshold is the key trigger; smaller commercial vehicles are not covered by this specific residential-district restriction. Separately, the County's Unified Development Ordinance regulates how commercial uses provide on-site parking and loading, so business operations on commercial or industrial parcels are governed by the zoning code rather than this residential-street rule.
