Idaho, Caribou County HVAC Permit Regulations and County Ordinances for Unincorporated Areas
Caribou County HVAC Permit Requirements
In Caribou County, the local Building Division does not issue permits for, nor does it perform inspections on, HVAC (mechanical), electrical, or plumbing work. These trade-specific permits and inspections are managed at the state level.
Jurisdiction for Unincorporated Areas
For all properties located in unincorporated areas of Caribou County, the Idaho Division of Occupational and Professional Licenses (DOPL)—formerly known as the Idaho Division of Building Safety (IDBS)—is the authority responsible for handling all HVAC, electrical, and plumbing permits and inspections. Property owners and contractors must coordinate directly with the state for these specific trade requirements, even while the county manages general building permits for structural work.

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.
