Whittier, CA Parking Rules: Oversized Vehicle Parking (2026)

Whittier does not use a single 'oversized vehicle' height-or-length ordinance; instead it controls large vehicles by weight and type. Under Section 10.16.140(B), regardless of whether a sign is posted, 'no person shall stop, stand or park any vehicle with a gross weight of six thousand pounds or more on any street or alley in the city for a period of time longer than thirty minutes between the hours of two a.m. and six a.m. of any day.' That captures most large RVs, heavy trucks, and box trucks overnight. For commercial vehicles, Section 10.40.020(A) bars parking any commercial vehicle of 10,000 pounds manufacturer's gross weight rating or more, or any truck tractor, on any street at all times, and Section 10.40.020(B) bars leaving unattached trailers, semitrailers, trailer coaches, and special construction or mobile equipment on a street. On residential property, Section 10.40.020(D) prohibits storing commercial vehicles over 14,000 pounds unladen plus tow trucks and trailers, and limits a lot to one commercial vehicle of 14,000 pounds or less. Recreational vehicles and utility trailers are excluded from the 10.40.020(D) residential limit, but they remain subject to the 6,000-pound overnight rule and the 72-hour street rule (Section 10.08.100). Vehicles transporting hazardous materials are separately regulated in Chapter 10.44.
