Utah County, UT Parking Rules: Commercial & Oversized Vehicles (2026)

UCLUO § 4.56, Storage Of Trucks In Certain Zones Prohibited, flatly prohibits the parking or other outdoor storage of trucks having a rated capacity of over one ton, commercial vehicles over one ton, and commercial construction equipment in every zone across unincorporated Utah County, with three narrow exceptions. First, such storage is allowed outright in the I-1 Industrial Zone. Second, trucks and equipment rated over one ton that are used exclusively for agricultural production and farm maintenance may be stored on an agricultural parcel that contains the farm dwelling, or on an adjacent agricultural parcel under the same ownership as the trucks and equipment. Third, agricultural equipment and vehicles actually under repair may be stored if they meet the land use ordinance's separate requirements for an approved agricultural equipment and vehicle repair facility.

Because the rule applies in all zones except those three carve-outs, it reaches residential, agricultural (outside the farm-use exception), and commercial zones alike: a homeowner in a residential zone cannot park a one-ton-plus box truck, dump truck, or similar heavy commercial vehicle outdoors on the property, and a contractor cannot store construction equipment there either, regardless of whether the vehicle is registered, running, or associated with a home-based business. The rule targets vehicle and equipment capacity and use, not ownership, so a resident's personally owned heavy truck used for a side business is treated the same as a company vehicle.
