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.
