San Jose, CA Parking Rules: Oversized Vehicle Parking (2026)

The County addresses oversized vehicles through several provisions rather than a single 'oversized vehicle' ordinance. Under the Stopping, Standing and Parking ordinance (Title B, Division B12, Chapter III), commercial vehicles with a gross-weight rating in excess of 10,000 pounds may not park in residential areas, though large commercial vehicles may park on public streets in industrial areas. Recreational vehicles, trailers, and boats kept on residential lots are limited by the Zoning Ordinance (Section 4.20.090): they must be registered to a person living at the property and may not be used as housing. The general 72-hour rule applies to oversized vehicles as well - any vehicle left standing on an unincorporated highway for 72 or more consecutive hours may be removed by CHP or the Sheriff under the Vehicle Code. Posted signs, weight-limit postings, and designated truck routes can further restrict where large vehicles may travel or stand. Unlike some neighboring cities (such as Santa Cruz) that have adopted dedicated 'oversized vehicle' parking-permit ordinances, the County primarily relies on the weight-based residential restriction, the recreational-vehicle zoning rule, and the 72-hour limit. Owners of large RVs, trailers, or trucks should confirm both the road rules with the Sheriff/Roads Department and the residential storage rules with County Planning before parking long term.
