Casper Zoning & Land Use Guide
Key Zoning Facts
Casper Zoning Overview
Casper is a city in Natrona County, Wyoming with approximately 58,313 residents. The city manages land use and development through its local zoning ordinance, which divides the municipality into districts regulating permitted uses, building heights, lot sizes, setbacks, and density.
Note that Wyoming has no statewide building code. Casper adopts and enforces its own building codes locally, typically based on the International Building Code (IBC) and International Residential Code (IRC).
Primary Zoning Districts
The R-1 (Single-Family Residential) district requires a minimum lot size of 7,500 sq ft with a 35 ft height limit and setbacks of 25 ft (front), 5 ft (side), and 20 ft (rear). The R-2 (Two-Family Residential) district requires a minimum lot size of 6,000 sq ft with a 35 ft height limit and setbacks of 20 ft (front), 5 ft (side), and 20 ft (rear). The R-3 (Multi-Family Residential) district allows varying lot sizes with a 45 ft height limit and setbacks of 20 ft (front), 10 ft (side), and 20 ft (rear). Commercial activity is served by the C-1 (Neighborhood Commercial), C-2 (General Commercial) districts. Industrial uses are accommodated by the I (Industrial) district.
ADU (Accessory Dwelling Unit) Rules
Wyoming does not have a statewide ADU mandate. Casper may allow accessory dwelling units under its local zoning ordinance. Contact the Casper Planning Department at (307) 235-8232 for current requirements including size limits, setbacks, owner-occupancy rules, and permitting procedures.
Development Process
Development in Casper generally requires obtaining the appropriate permits from the city's planning and building departments. The process typically involves:
- Zoning Verification — Confirm that your proposed use is permitted in the applicable zoning district
- Site Plan Review — For commercial and multi-family projects, submit a site plan for review
- Building Permit — Apply for a building permit with construction documents
- Inspections — Schedule required inspections during construction
- Certificate of Occupancy — Obtain final approval before occupying the structure
For projects that do not conform to existing zoning, property owners may need to seek a variance, special exception, or rezoning through the local board of zoning appeals or planning commission.
Key Considerations
Before starting any development project in Casper, property owners should:
- Verify the zoning classification of their property
- Review setback, height, and lot coverage requirements for their specific district
- Check for any overlay districts or special regulations
- Determine if the property is in a flood zone using FEMA's flood map service
- Confirm whether HOA covenants or deed restrictions apply
- Contact the Planning Department at (307) 235-8232 for pre-application guidance
