Lake Forest, CA Parking Rules: Oversized Vehicle Parking (2026)

Lake Forest's oversized-vehicle rule sits in Title 12, Chapter 12.16 of the Municipal Code (Section 12.16.070). It prohibits any vehicle from being stopped, parked, or left standing on a public street if the vehicle exceeds 22 feet in length, has more than two axles, is a commercial vehicle greater than seven feet in height, weighs more than 10,000 pounds, or exceeds 90 inches in width as measured at the widest portion of the body. When an oversized vehicle is allowed to park, it is limited to active loading or unloading of persons or property, work in connection with a service, or performing emergency repairs to the vehicle, for a maximum of 72 consecutive hours. The city pairs this prohibition with a permit program: in neighborhoods subject to oversized-vehicle parking restrictions, residents and visitors must display a parking permit placard to avoid a citation, and both permanent and temporary permits are available through an application process administered by the city. Trailers attached to vehicles are also targeted in residential areas to discourage long-term street storage and protect neighborhood aesthetics, with exceptions for loading and unloading and for trailers on private property. Mobile vending vehicles actively engaged in commercial vending are exempt from the oversized-vehicle prohibition but must obtain a Commercial Vending Vehicle (CVV) permit. These local limits rely on California Vehicle Code Sections 22507 and 35701, which let cities regulate the parking of oversized and heavy vehicles on designated streets. Enforcement is by Orange County Sheriff (Lake Forest Police Services) and city parking-control staff.
