Permit Requirements for Loma, Montana
For HVAC projects in Loma, determining the correct permitting authority depends on whether the project site is located within the incorporated city limits or in an unincorporated area of Chouteau County.
Authority Having Jurisdiction (AHJ)
Most jurisdictions require permits for HVAC work to ensure safety and code compliance. The governing body responsible for issuing these permits varies by specific location:
General HVAC Guidelines
Permits are usually required for new installations, structural modifications, or major repairs. While minor maintenance or cosmetic updates may be exempt, landowners should always verify local codes before work begins.

Because Loma is located within Chouteau County, the following broader county regulations may also apply to your project:

Chouteau County Building and Safety Jurisdiction
Chouteau County does not operate its own comprehensive local building department for mechanical or HVAC permitting. Instead, building and mechanical permitting in unincorporated areas of Chouteau County is generally handled at the state level through the Montana Department of Labor & Industry's Building Codes Program. If a property is located within the limits of an incorporated city or town, the local municipal building department holds jurisdiction for permits, not the county.
Rules for Properties in Unincorporated Areas
In unincorporated Chouteau County, mechanical and HVAC work is subject to state-adopted codes, including the International Mechanical Code (IMC) and the International Fuel Gas Code (IFGC). While the county manages development permits for land use, structural, and zoning purposes, mechanical permits for HVAC installations, replacements, or alterations are typically processed through the state's Building Codes Bureau.
Key considerations for unincorporated areas include:
- Permit Necessity: A state mechanical permit is generally required for new buildings, alterations, additions, and repairs involving HVAC systems.
- Exemptions: Certain structures, such as farm and ranch buildings, mining buildings on mining property, and residential buildings containing less than five dwelling units, may be exempt from state mechanical permit requirements.
- Contractor Requirements: While Montana does not issue a specific "HVAC license," contractors must be registered with the Montana Department of Labor & Industry as a construction contractor or hold an Independent Contractor Exemption Certificate (ICEC). Additionally, technicians handling refrigerants must hold federal EPA Section 608 certification.
- Verification: Because enforcement can be complex in rural areas, property owners and contractors should verify specific project requirements directly with the Montana Building Codes Program before beginning work to ensure compliance with state codes and insurance requirements.

Montana Hvac Legislation, Codes, and Guidelines
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.
