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

Sec. 18-222, the city's property-maintenance nuisance ordinance, opens by declaring it unlawful and a public nuisance for anyone owning, leasing, occupying or controlling residential, agricultural, commercial, industrial, business park, office, educational, religious, vacant or other premises in Pomona to maintain the property in violation of any of the 43 conditions the section lists. Item (25) targets oversized commercial equipment specifically: construction equipment, buses, tow trucks, taxicabs and other vehicles-for-hire, dump trucks, flatbed trucks, grading equipment, tractors, tractor trailers, truck trailers, and any commercial vehicle exceeding 25 feet in length, eight feet in height or 80 inches in width, together with the supplies, materials or machinery that go with them, may not be parked or stored on any street or on any property in a residential zone unless another Code section or state law specifically permits it. The section defines "commercial vehicle" broadly as any motorized or non-motorized vehicle used or maintained to transport property or goods for profit, or persons for hire or compensation, so delivery vans, tow trucks and taxis operated for pay all fall within the size thresholds if they exceed them.

Because this restriction lives in the nuisance chapter rather than the traffic chapter, it is enforced by the city's code compliance division through the nuisance abatement process, not by a routine parking citation alone. Sec. 18-222 works alongside the separate large-vehicle street-parking rules in Chapter 58, Division 2 (Secs. 58-300 through 58-306), which impose their own citywide overnight and four-hour on-street limits regardless of zoning.
