Goshen County HVAC Permit Requirements
Goshen County, Wyoming, does not have its own zoning regulations or building inspections. Therefore, building permits for properties in unincorporated areas of Goshen County are issued by the county itself. However, if a property is located within an incorporated city, that city's building department is responsible for issuing permits, not the county.
For HVAC work, a mechanical permit is generally required for new installations, system replacements, and ductwork modifications. While Wyoming does not have a statewide HVAC contractor license, technicians must comply with local city or county licensing requirements. Additionally, EPA Section 608 certification is required for handling refrigerants.
It is important to note that permit rules and fees can change, so it is advisable to confirm current requirements directly with the relevant city or county department before applying.
Rules for Properties in Unincorporated Areas
Goshen County issues building permits for properties located in unincorporated areas of the county. The county's Planning and GIS department handles applications and forms related to subdivisions and other planning matters. While the county does not have specific zoning regulations or building inspections, it is responsible for issuing permits for construction in unincorporated areas.

The following statewide building codes and regulations apply universally to all jurisdictions within Wyoming:

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:
- 2024 International Mechanical Code (IMC)
- 2024 International Fuel Gas Code (IFGC)
- 2024 International Building Code (IBC)
- 2024 International Existing Building Code (IEBC)
- 2024 International Fire Code (IFC)
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.
