May I park or store a commercial vehicle at my house?

No. It shall be unlawful for a commercial vehicle, commercial trailer, semi tractors, tractor trailers, step vans, cargo vans, box trucks, busses, or concession vehicles, with a greater than one-ton rated capacity to be parked on any property whose primary use is residential.  No commercial vehicles may be parked on city streets or the right of way unless they are on a professional job. No semi-tractors or trailers may be parked or stored on any residential property.
