Wyoming, Washakie County HVAC Permit Regulations and County Ordinances for Unincorporated Areas

Washakie County HVAC Permit Requirements

Washakie County, Wyoming, handles building and development permits for all unincorporated areas through its Planning and Zoning Office. Properties within the incorporated city limits of Worland or Ten Sleep are not served by this county office. The specific requirements for HVAC permits can vary depending on whether Washakie County has adopted a building code. Generally, permits are required for new residential and commercial construction, additions, structural alterations, and accessory structures exceeding a certain size threshold.

Agricultural structures on working farms may have limited or no permit requirements, but it is essential to confirm this with the county office before assuming exemption.

For properties in unincorporated areas, it is recommended to contact the Washakie County Planning and Zoning Office directly to confirm project-specific permit needs and any adopted building codes. The office can be reached at (307) 347-3131.

When applying for a permit, you will typically need to provide a site plan, construction drawings, property information, and contractor details if applicable. The application process generally involves submitting these documents in person at the County Courthouse and paying associated fees.

Electrical work on a permitted project requires a licensed electrician. While Wyoming does not have a statewide general contractor license requirement, HVAC and plumbing may have local or state registration requirements that should be verified with the county and relevant state boards.

State-Level Building Codes and Legislation for HVAC in Wyoming

Wyoming does not have a single, mandatory statewide building code that applies to all construction. Instead, the state adopts specific codes that are primarily enforced at the local jurisdictional level (cities and counties). Under Wyoming Statute § 35-9-106, the Wyoming Department of Fire Prevention and Electrical Safety (WDFPES) is authorized to establish minimum fire and electrical safety standards for buildings. While the state adopts these standards, local jurisdictions may choose to adopt and enforce them, often with local amendments.

As of June 28, 2024, the State of Wyoming has adopted the 2024 editions of the International Codes (I-Codes). These codes, which govern HVAC, mechanical, and fuel gas installations, include:

The Wyoming Department of Fire Prevention and Electrical Safety (WDFPES), led by the State Fire Marshal, is the primary agency responsible for adopting these standards. The WDFPES also conducts plan reviews and inspections for specific types of buildings as mandated by Wyoming Statute § 35-9-108, including state-owned or leased buildings, schools, multi-story public buildings, and public buildings over 5,000 square feet. For most other residential and commercial projects, enforcement is handled by local building departments, which are required by state law to adopt or maintain standards that at least meet the statewide standards if they choose to act as a local enforcement authority.
