Maricopa, AZ Parking Rules: Commercial Vehicle Restrictions (2026)

Within the incorporated City of Maricopa, commercial-vehicle parking is governed by the City's own Municipal Code Chapter 10.20 (Stopping, Standing and Parking) and the truck-route rules in MCC 10.30, not by Maricopa County's residential parking ordinance. Under Chapter 10.20, a person may not stand or park a heavy vehicle exceeding the code's gross-vehicle-weight rating and one-ton chassis rating, or a tractor or semitrailer, on a residential-zone street or any street not designated as a truck route, except for the purpose of loading, unloading, delivering, picking up, or making a service call, or while the vehicle is performing routine or emergency maintenance to utilities, transportation facilities, or private property. MCC 10.30.010 (Truck routes) further requires regulated trucks to use designated truck routes and, when making a local delivery, to take the shortest route from a truck route to the delivery point. 'Commercial vehicle' is defined in MCC 18.205.020 as a vehicle registered as commercial and used primarily in conducting a business rather than for private use.
