Antioch, CA Parking Rules: Commercial & Oversized Vehicles (2026)

1223 prohibits parking any motor vehicle used for commercial, industrial, or agricultural purposes and rated more than one ton capacity, and any trailer used for the same purposes, in a residential district anywhere in Antioch. The ban covers standing the vehicle on a residential street or lot, not just driving it through, so a delivery truck or dump truck over the one-ton threshold cannot simply park overnight in a residential neighborhood. Two exceptions apply: first, the vehicle or trailer can be present if it is actively loading, unloading, or rendering service, covering, for example, a moving truck or a service vehicle while work is underway; second, trucks used for agricultural purposes can be parked or stored in the buildable area of a residentially zoned parcel where at least five acres of that parcel are devoted to agricultural use, recognizing Antioch's remaining rural-edge parcels along the Delta. 1, which covers boats, campers, and trailers rather than commercial trucks. 202.
