ADU Design in Wyoming: what governs your project
Wyoming has no statewide ADU statute; accessory dwellings are governed by each city's zoning ordinance. Cheyenne, Casper, and Jackson each set their own standards for secondary units.
Energy code
Permitting varies by jurisdiction: typical local rules address size limits relative to the primary home, off-street parking, and standard building permits. Foundation and frost-depth requirements follow the state building code.
Permitting & plan check
Cheyenne, Casper, and larger cities maintain their own building departments; many smaller towns and counties use third-party review or minimal local review. Energy and mineral development projects often move through county-level permitting. Review timelines are generally short outside the busiest jurisdictions.
Good to know
- Western Wyoming near the Teton fault has the state's highest seismic hazard.
