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.
