Aliso Viejo, CA Parking Rules: Overnight Parking (2026)

Aliso Viejo's overnight rules sit in Chapter 9.04 of the Municipal Code. The baseline is § 9.04.040(C): no operator of any vehicle shall stop, stand, park or leave standing any vehicle, attended or unattended, on a city street for a period of time longer than 72 consecutive hours. The general exception in the section covers stops necessary to avoid conflict with other traffic or in compliance with the direction of a police officer, other authorized officer or official traffic control device.

The removal section backs it up. Section 9.04.070 authorizes removal of vehicles from a city street under California Vehicle Code Section 22650 et seq. when a vehicle is parked or left standing for 72 or more consecutive hours. The definitions in § 9.02.030 add that to park or leave standing includes failing to move a vehicle at least one-tenth of a mile as measured on the odometer during the time period specified, or, without an odometer reading, failing to move at least 100 feet, measured from axle to axle, from the last marked location.

Oversized vehicles face a tighter overnight limit under § 9.04.090, amended by Ord. 2025-247. Subsection A bars parking or leaving standing any oversized vehicle on any city street or highway between 2:00 a.m. and 6:00 a.m. on two consecutive days. Subsection B bars parking more than 12 consecutive hours between 6:00 a.m. and 2:00 a.m. on two consecutive days. An oversized vehicle is one longer than 24 feet, heavier than 10,000 pounds, or wider than 84 inches in the categories the section defines, or any farm or special purpose machinery. Exceptions in subsection C cover active loading or unloading, a service to a property in the same block, and emergency repairs on the vehicle itself. Authorized emergency vehicles are outside the section.

Overnight sleeping in a vehicle is a separate rule: § 9.04.050(A) makes it unlawful to camp or lodge in any vehicle on a city street, and any window coverings have to stay open at all times.
