Newport Beach, CA Parking Rules: Oversized Vehicle Parking (2026)

For private residential property, the County of Orange Codified Ordinance Sec. 3-13-4(15) sets the size threshold for oversized/commercial vehicles: it is unlawful to keep in any residential zone or on residentially-developed property any commercial vehicle over 25 feet in length, over 8 feet in height, or over 90 inches in width, along with named heavy vehicles such as buses, dump trucks, flatbed trucks, tractors, tractor-trailers, and truck trailers. Table 3-13-6(c) of Sec. 3-13-6 likewise excludes those oversized commercial vehicles from the residential vehicle-storage allowances. Recreational vehicles (motorhomes, large trailers, boats) are handled separately under Sec. 3-13-6/Table 3-13-6(c) and may be stored on a paved driveway or screened paved area, but not on unpaved ground. On public streets, the California Vehicle Code controls: CVC 22507 authorizes local authorities to prohibit or restrict, by ordinance, the parking of vehicles - including vehicles six feet or more in height within 100 feet of an intersection - on designated streets, but the restriction does not take effect until signs or markings giving adequate notice have been posted. Drivers of oversized vehicles in unincorporated communities should check for posted street signage and keep large commercial vehicles off residential lots.
