Pomona Commercial Vehicle Restrictions Rules (2026): What You Need to Know

Pomona Municipal Code Article X and the zoning ordinance jointly restrict commercial vehicle parking in residential areas. The primary prohibition targets commercial vehicles with a gross vehicle weight rating (GVWR) exceeding 10,000 pounds — a threshold that includes medium-duty trucks, box trucks, flatbeds, tow trucks, semi-tractors, and heavy equipment trailers. These vehicles may not park on any residential street between 10 PM and 6 AM. The restriction applies to on-street parking in all residentially zoned areas throughout the city, and enforcement increases around neighborhoods that border commercial and industrial corridors.

During daytime hours, commercial vehicles of any size that are actively engaged in delivering goods, picking up materials, or performing contracted service work at a nearby residence are temporarily exempt from the restriction for the time reasonably necessary to complete the job. However, parking a commercial vehicle on a residential street overnight as a matter of routine — effectively using the street as a commercial depot or vehicle storage yard — is prohibited regardless of the vehicle's weight. This provision targets contractors, landscaping companies, and logistics operators who might otherwise store fleet vehicles in residential neighborhoods.

Detached trailers — including utility trailers, equipment trailers, and semi-trailers — may not be stored on any public street in a residential zone at any time. Trailers must be stored on private property behind fencing or in an enclosed structure. On residential lots, Pomona's zoning code further limits commercial vehicle storage: vehicles over 10,000 lbs GVWR may not be stored in front yards or driveways, and must be parked in a side or rear yard screened from view if stored on-site at all. Enforcement is complaint-driven through the Pomona Police Department at (909) 620-2155 and Code Enforcement at (909) 620-2171.
