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

The County of Orange Codified Ordinance Sec. 3-13-4(15) lists prohibited conduct on residential property in unincorporated county territory. It is unlawful to keep, store, or maintain in any residential zone or on any residentially-developed property: (a) construction and/or business equipment, supplies, materials, or machinery of any type, or commercial containers; (b) buses, tow trucks, dump trucks, flatbed trucks, tractors, tractor-trailers, or truck trailers; or (c) any other commercial vehicle over 25 feet long or 8 feet in height or 90 inches wide. The vehicle-storage table (Table 3-13-6(c)) likewise excludes those heavy commercial vehicles from the residential storage allowances. On public streets, the California Vehicle Code controls: CVC 22507 authorizes local authorities to restrict commercial-vehicle parking, and posting requirements apply before residential commercial-vehicle parking limits take effect. OC Neighborhood Preservation lists 'Commercial Vehicle in Residential Zone' among its common violations, tied to Title 3, Division 13. Property owners should keep large commercial vehicles, trailers, and equipment off residential lots and in properly zoned commercial or industrial locations, or in approved enclosed/screened storage where permitted.
