Building Setbacks & Zoning in Cheyenne, WY: What Residents Actually Need to Know
If you live in Cheyenne or are thinking about moving there, building setbacks & zoning are one of those things you probably won't think about until they affect you directly. Cheyenne has 3 specific rules on the books covering different aspects of building setbacks & zoning, and some of them might surprise you.
Lot Coverage Limits
Cheyenne's Unified Development Code caps building footprint at 60% of lot area for the standard single-family lot type used across most of the city's residential districts.
Key details: Standard Lot (DD6) max: 60% of lot area. Large/Low-density lot max: 40% of lot area. Urban Lot (DD8) max: 70% of lot area. Rural/Agriculture lots: no coverage limit (n/a).
Building plans exceeding the applicable coverage ratio are not approved for permit until the design is revised to fit within the limit for that lot type and district.
Structure Height Limits
Cheyenne's Unified Development Code limits detached houses in its standard residential lot types to three stories, and accessory buildings like garages and sheds can never rise taller than the main house.
Key details: Principal building max: 3 stories. Accessory building cap: No taller than house. Applies in: MR, HR, NR-1, NR-2, NR-3. Source table: UDC Table 5-2.
A building or accessory structure that exceeds the story limit fails Planning & Development plan review; the applicant must revise plans or seek a variance before a permit or certificate of occupancy issues.
Setback Rules
Cheyenne's Unified Development Code sets minimum front, side, and rear yard setbacks for every zoning district and lot type, from 25 feet all around on agricultural lots to as little as zero feet for party-wall attached dwellings.
Key details: Agriculture lot setback: 25 ft front, side, and rear. Zones: AG, AR agricultural districts. Accessory setback: Behind front line, 25 ft sides/rear. Enforcing agency: Planning and Development Department. Minimum lot area: 20 acres (Agriculture Lot type).
Building without the required setback violates the UDC and can trigger permit denial, a stop-work order, or removal of the encroaching structure at the owner's expense.
The Bottom Line
Cheyenne's building setbacks & zoning rules are a mixed bag. Some areas are strict, others are relaxed, and the details matter. The best approach is to check the specific rule that applies to your situation rather than assuming Cheyenne is broadly strict or permissive.
These rules come from Cheyenne's publicly available municipal code. For complete penalty schedules, exemption details, and answers to common questions, see the individual ordinance pages throughout this guide.
