Summary
Sunnyvale allows overnight street parking on most residential streets subject to the 72-hour rule. Permit Parking Districts require a valid permit overnight.
(k) If a vehicle is parked or left standing upon a highway for 72 or more consecutive hours in violation of a local ordinance authorizing removal. (l) If a vehicle is illegally parked on a highway in violation of a local ordinance forbidding standing or parking and the use of a highway, or a portion thereof, is necessary for the cleaning, repair, or construction of the highway, or for the installation of underground utilities, and signs giving notice that the vehicle may be removed are erected or placed at least 24 hours prior to the removal by a local authority pursuant to the ordinance.
Full Breakdown
Overnight parking on Sunnyvale public streets is generally permitted for passenger vehicles, with the exception of Permit Parking Districts and posted no-parking zones. In designated Permit Parking Districts such as portions of the Heritage District, Downtown, and neighborhoods near Caltrain, vehicles must display a valid residential or guest permit overnight. The citywide 72-hour rule (CVC 22651(k) and SMC Title 10) still applies, so a parked vehicle must be moved at least every three days. Oversized and commercial vehicles cannot be parked overnight in residential areas. During storm or street-sweeping operations, posted signs may temporarily override overnight parking. Individuals cannot live in vehicles on public streets under SMC provisions and state law enforcement practices.
