Lemhi County HVAC Permit Requirements
In Lemhi County, Idaho, a building permit is required before commencing any construction, including HVAC installations, on properties in unincorporated areas. The Lemhi County Building Department is responsible for administering these permits and ensuring compliance with adopted building codes, which include the Idaho Building Code (2018 IBC with amendments) and the Idaho Residential Code (2020 IRC with amendments).
For HVAC work specifically, while state-level licensing for HVAC contractors is layered and involves the Idaho Contractors Board for public works projects, private residential and commercial HVAC work primarily falls under local jurisdiction requirements. It is essential to contact the Lemhi County Building Department to determine the exact permit requirements for your specific HVAC project.
When applying for a building permit that includes HVAC work, you will typically need to provide:
- A completed building permit application form.
- A site plan showing the location of the HVAC equipment and compliance with setback requirements.
- Project plans and specifications, which should include details about the heating, cooling, and ventilation systems. This includes the location, type, and fuel source of all fuel-burning appliances, an installation plan, and a heat calculation.
- Documentation of compliance with zoning requirements.
- For new construction, a septic permit from Eastern Idaho Public Health may also be required.
Contractors performing work valued over $2,000 in materials and labor must register with the Idaho Contractors Board.

The following statewide building codes and regulations apply universally to all jurisdictions within Idaho:
Idaho Hvac Legislation, Codes, and Guidelines
State Statutes and Adopted HVAC Codes
In Idaho, the regulation of heating, ventilation, and air conditioning (HVAC) systems is governed by Title 54, Chapter 50 of the Idaho Code. This legislation establishes the legal framework for the installation, improvement, extension, and alteration of HVAC systems throughout the state. To ensure safety and efficiency, Idaho adopts and enforces specific model codes published by the International Code Council (ICC). As of the most recent regulatory information, the state utilizes the 2018 editions of the International Mechanical Code (IMC), the International Fuel Gas Code (IFGC), and Parts V and VI of the International Residential Code (IRC). These codes set the minimum standards for equipment installation, ventilation rates, combustion air calculations, and venting configurations.
Primary State Board and Agencies
The primary state-level authority responsible for administering these standards is the Idaho Division of Building Safety (DBS), which operates under the Idaho Division of Occupational and Professional Licenses (DOPL). The Idaho Heating, Ventilation, and Air Conditioning Board, housed within this structure, is responsible for promulgating rules, overseeing contractor licensing, and ensuring compliance with the adopted codes. While the state sets these minimum standards, it is important to note that Idaho operates a dual-track system; many counties and incorporated cities maintain their own building departments and may act as the local Authority Having Jurisdiction (AHJ) for issuing mechanical permits and conducting inspections, provided their programs meet or exceed state requirements.
