Idaho, Blaine County HVAC Permit Regulations and County Ordinances for Unincorporated Areas
Blaine County Building & Safety Division Jurisdiction
In Blaine County, the Building Services Department oversees the issuance of building permits for structural and zoning compliance. However, the county does not directly issue trade-specific permits for HVAC, plumbing, or electrical work. These trade permits are managed at the state level.
Rules for Properties in Unincorporated Areas
For properties located in unincorporated areas of Blaine County, the following requirements apply regarding HVAC installations:
- State-Level Permitting: HVAC permits are not issued by the Blaine County Building Department. Instead, they must be obtained through the State of Idaho.
- Permit Coordination: While you must obtain a building permit from Blaine County for general construction, you are responsible for separately securing the necessary HVAC permit from the State of Idaho.
- Compliance: All work must comply with applicable state codes. It is recommended to verify current requirements and the application process directly with the state authorities or the county building department, which can provide guidance on the necessary steps for your specific project.

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.
