HVAC Permit Requirements in Big Horn County, Montana
Big Horn County does not operate its own certified building code enforcement program. Consequently, there is no county-level building or safety division that issues HVAC or mechanical permits for unincorporated areas of the county.
For properties located in unincorporated areas of Big Horn County, building and mechanical code enforcement falls under the jurisdiction of the Montana Building Codes Program. If a project requires a mechanical permit under state regulations, it must be obtained through this state-level authority.
It is important to note that state law provides exemptions for certain types of buildings, such as farm and ranch buildings, mining buildings on mining property, and residential buildings containing fewer than five dwelling units (unless they serve transient guests). If your property is located within an incorporated city, you must contact that city's specific building department, as they may have their own local permitting processes and requirements that differ from the state-level standards.

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.
