Coconino County, AZ Parking Rules: Commercial & Oversized Vehicles (2026)

Coconino County's Zoning Ordinance restricts where large trucks can sit on residential property throughout the unincorporated county. E, governing the Single Family Residential Zones, states that Commercial Vehicles exceeding 26,000 pounds Gross Vehicle Weight, along with associated Commercial Equipment such as semi-tractors, semi-trailers, dump trucks, and equipment trailers, may not be parked, stored, or serviced in any residential zone. A, though that section adds an exemption: vehicles used for Exempt Agricultural purposes are excused if the owner holds a Certificate of Agricultural Exemption for the parcel.

D: overnight parking of Commercial Vehicles and Commercial Equipment, expressly naming semi-tractors, semi-trailers, dump trucks, equipment trailers, and backhoes, is prohibited outright, with no agricultural carve-out. All three provisions sit inside each zone's Performance Standards subsection alongside ordinary passenger-vehicle parking rules, which separately bar using required front and street-side setbacks for storing any vehicle or accessory. 3 allows the county to revoke or halt work under any permit issued in conflict with these standards.
