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

Municipal Code Section 3173(a) prohibits parking or leaving standing, on any public street or on public or private property, a commercial vehicle whose manufacturer's unladen weight exceeds 6,000 pounds, whose width exceeds 84 inches at its widest point, or whose height exceeds 84 inches, along with any trailer or commercial equipment regardless of weight. The ban lifts only in an industrial zone, excluding parking buffer zones, while a vehicle, trailer, or equipment is actively being loaded or unloaded in aid of a service to a property on the same block, when the vehicle is immobilized by an accident or mechanical breakdown for up to eight hours, or when a trailer stays attached to a motor vehicle able to move it.

Subsection (b) exempts ordinary pickup trucks under California Vehicle Code Sections 471 and 260 that are not used commercially, plus commercial vehicles stored on private, commercially zoned property owned by the same business. Subsection (c) exempts a hotel or motel guest's commercial vehicle parked in an approved designated area on the property, though any such parking area approved after the ordinance's effective date needs Planning Commission conditional-use-permit approval under Section 9824. Subsection (d) lets the city tow and store any vehicle parked in violation, and subsection (i) caps any City Manager-authorized exception at 90 minutes per vehicle in any 24-hour period absent prior Council approval. A single carve-out street segment, both sides of Washburn Road between Woodruff Avenue and Regentview Avenue, is excluded entirely under subsection (j).
