Summary

Unincorporated Santa Clara County has no blanket overnight parking ban on public streets, but CVC 22651(k) allows towing of vehicles parked over 72 hours in one spot.

Full Breakdown

Santa Clara County does not prohibit overnight parking on most unincorporated county roads, which is a contrast to many incorporated cities in the region. However, California Vehicle Code section 22651(k) authorizes the Sheriff and Roads Department to tow any vehicle that has been parked in the same public spot for more than 72 consecutive hours. Residents who observe an unfamiliar vehicle parked for over 3 days can call the Sheriff non-emergency line to request a 72-hour posting. Commercial vehicles over 10,000 pounds are restricted from overnight residential parking under CVC 22507.5 where the county has posted signs. Recreational vehicles and oversized vehicles are not allowed to be used as dwellings on public streets. In designated fire hazard severity zones and hillside areas, parking may be seasonally restricted during red flag warnings to maintain evacuation routes.
