Summary

In unincorporated Weld County, parking a commercial vehicle (semi-tractor, dump truck, box truck, construction equipment) at a residence requires a zoning permit and the lot must be a legal lot of at least one acre. Uses allowed by right in the Agricultural zone are exempt.

City-specific rules exist: Greeley has its own commercial & oversized vehicles rules that differ from Weld County's county-level regulations. If you live in Greeley, check the city-specific page instead.

The property upon which the commercial vehicle is located is a legal lot of at least one acre.

Full Breakdown

Weld County Code §23-1-90 defines a commercial vehicle as any vehicle used or previously used commercially, excluding uses listed by right in the A (Agricultural) Zone District, and includes semi-tractors and trailers, dump trucks, construction equipment, box trucks and tow trucks. Where such parking is allowed under Article III, §23-4-950 requires a Zoning Permit for a Commercial Vehicle (ZPCV), issued only if the property is a legal lot of at least one acre, the vehicle is compatible with the surrounding area, carries current registration and plates, and is removed when the use ceases. In Greeley, commercial vehicles parked in areas zoned residential may be towed under Municipal Code §16-685(b).

Violations & Fines

Parking a commercial vehicle without the required ZPCV is a Chapter 23 zoning violation abated by Weld County Code Compliance through notice and administrative penalties. In Greeley, residential-zone commercial vehicles are towed after notice (§16-685).

Frequently Asked Questions

Can I park my semi-truck at my Weld County home?
Only with a Zoning Permit for a Commercial Vehicle, and only if your property is a legal lot of at least one acre. Agricultural uses allowed by right are exempt.
Does this apply to my work pickup?
The rule targets commercial vehicles like semis, dump trucks and construction equipment. A personal-use pickup is generally not a regulated commercial vehicle; check §23-1-90 for definitions.
