Idaho, Lemhi County HVAC Permit Regulations and County Ordinances for Unincorporated Areas
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 Lemhi County Building Department is located at 200 Fulton Street, Suite 204, Salmon, ID 83467. You can contact them by phone at (208) 742-1703.
