Minidoka County HVAC Permit Requirements
Minidoka County, Idaho, has specific requirements for HVAC permits, generally aligning with state building codes. The county's Building and Zoning Department handles permitting for Minidoka County and the cities of Acequia, Minidoka, Paul, and Rupert. For properties in unincorporated areas, the Minidoka County Building Department is the relevant authority. Generally, any work involving the construction, enlargement, alteration, repair, movement, conversion, or replacement of mechanical systems, including HVAC, requires a building permit. However, certain minor repairs or specific accessory structures may be exempt.
For new residential construction, Manual J design documents are required for mechanical permit applications as of February 1, 2021. The county has adopted the 2018 International Mechanical Code and the 2018 International Fuel Gas Code, which dictate installation standards for HVAC and fuel gas systems.
It's important to note that while Minidoka County processes building and mechanical permits, plumbing and electrical permits and inspections are handled by the State of Idaho. Licensed contractors are required to perform HVAC work in Idaho.

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.
