Teton County, Wyoming HVAC Permit Requirements

Teton County, Wyoming's Building and Planning Services Department handles permit requirements for properties located in unincorporated areas of the county. If your property is within an incorporated city, that city's building department is responsible for permits. HVAC permits fall under the category of "Trade Permits" (Mechanical, Plumbing, Demo) and can be applied for through the Teton County Online Portal. These permits typically do not require a scheduled submission week and are often issued within 48 hours if submitted correctly with all necessary documentation. It is important not to pay fees until you receive an email confirmation from the Permit Technician. Trade permits require a Warranty Deed and a Letter of Authorization if the applicant is not the homeowner.

For properties in unincorporated areas, Teton County is the governing jurisdiction. The county's Building Division is responsible for issuing permits for these areas. If you are unsure whether your property is in an incorporated or unincorporated area, it is best to contact the Teton County Planning and Building Services Department directly.

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.
