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

Upland does not have a single 'oversized vehicle' street ordinance; instead, oversized vehicles are limited by overlapping rules. Heavy commercial vehicles, trailers, and related equipment weighing three tons or more unladen are prohibited from parking in residential areas, and no more than two commercial vehicles may be kept on a single-family lot. Recreational vehicles, boats, and trailers may occupy a required front or street-side setback for no more than 72 hours and must be moved to an enclosed garage or screened side/rear yard for longer storage. The City's no-parking provisions (UMC 10.36.040) prohibit parking on any street where the roadway is needed for the movement of equipment, articles, or structures of unusual size when a parked vehicle would interfere with that movement. On the public street, large-vehicle parking is also governed by the California Vehicle Code, which authorizes posted weight limits on residential streets (CVC 22507.5) and lets the City restrict heavy vehicles via signage. Because Upland controls residential storage through zoning while the state controls much of on-street heavy-vehicle parking, owners should check both the property's zoning rules and posted street signs.
