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

14's public nuisance code, in subsection D, 'Vehicle and Vehicle Repair Nuisances,' alongside four related conditions. Item 3 targets visibility, not mere ownership: a heavy commercial vehicle, military vehicle, construction equipment, or machinery of any type or description parked or stored anywhere on residential or commercial property becomes a nuisance the moment it can be seen by the general public from a sidewalk, trail, alley, or right-of-way, unless the owner has a valid permit. Two exceptions apply. The vehicle or equipment is exempt while active excavation, construction, or demolition work is underway under a building permit on the same property or an adjoining one, covering a contractor's rig parked next to a house under renovation. It is also exempt if state law itself exempts that particular vehicle or equipment. 270's front-yard recreational-vehicle limits.
