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

Siskiyou County's published code does not include a specific county-wide residential commercial-vehicle parking ban of the kind found in dense cities. Where a commercial vehicle parks on a County road, the California Vehicle Code applies: CVC Section 22500 governs unlawful stopping and parking, and CVC Division 15 (Size, Weight and Load) sets statewide limits. For example, CVC Section 35550 caps the gross weight on any one axle at 20,000 pounds and on any one wheel/wheels supporting one end of an axle at 10,500 pounds. State law (CVC Section 22507) lets local authorities restrict commercial vehicles of 10,000 pounds or more in residential districts only by ordinance after a noticed public hearing, with exceptions for active pickups and deliveries; Siskiyou County has no such published county-wide residential restriction. Operating a business from a home, including parking of business vehicles and equipment, is regulated under Title 10 zoning's use standards rather than a traffic ordinance, and complaints are handled by the Planning Division's code enforcement as potential nuisances. During winter, Ordinance No. 770 still applies to commercial vehicles: trucks obstructing snow-removal operations in the roadway may be removed and stored at the owner's expense.
