HVAC Permit Authority in Cascade County
Cascade County does not have a local building or mechanical department that issues HVAC permits. Instead, building code enforcement, including mechanical and HVAC systems, is handled at the state level by the Montana Department of Labor and Industry (DLI) Building Codes Program. The Cascade County Planning and GIS Department is responsible for zoning and land use (such as Location/Conformance permits), but they do not enforce building or mechanical codes.
Rules for Properties in Unincorporated Areas
For properties located in unincorporated areas of Cascade County, the following rules apply regarding HVAC and mechanical work:
- State Jurisdiction: Mechanical permits for HVAC systems are administered by the Montana Department of Labor and Industry (DLI). You must apply for these permits through the state's eBiz portal or by contacting the DLI Building Codes Program directly.
- Permit Requirements: A state mechanical permit is generally required for new buildings, alterations, additions, and repairs to heating, ventilating, air-conditioning, and other mechanical systems.
- Exemptions: Certain structures are exempt from state mechanical permit requirements, such as farm and ranch buildings, mining buildings, and residential buildings containing less than five dwelling units. It is recommended to contact the DLI Building Codes Program to confirm if your specific project requires a permit.
- Inspections: Mechanical permit holders are responsible for ensuring work meets state building codes (including the International Mechanical Code and International Fuel Gas Code) and must coordinate required inspections (such as gas piping pressure tests, rough-in, and final inspections) with the state inspector assigned to the area.
- Zoning vs. Building Codes: While you may not need a county building permit for HVAC work, you must still ensure your project complies with any applicable county zoning regulations. Contact the Cascade County Planning and GIS Department to verify if your property is within a zoning jurisdictional area and if any land-use permits are required for your project.

Montana HVAC Building Codes and Legislation
The State of Montana enforces a statewide building code system that incorporates several model codes by reference. These codes are amended at the state level to address specific regional needs, such as snow loads and energy efficiency. For HVAC systems, the state has adopted the 2021 editions of the International Mechanical Code (IMC) and the International Fuel Gas Code (IFGC), along with the 2021 International Energy Conservation Code (IECC).
Regulatory Authority and Adoption
The primary agency responsible for establishing and enforcing these standards is the Montana Department of Labor & Industry (DLI), specifically through the Building Codes Program within the Business Standards Division. The state adopts these codes through the Administrative Rules of Montana (ARM), specifically under Title 24, Chapter 301. While the state sets the baseline, local jurisdictions (cities, counties, or towns) may be certified to enforce these codes locally. In areas without a certified local program, the state's Building Codes Program serves as the authority having jurisdiction.
