Granite County HVAC Permit Requirements
Granite County, Montana, does not have its own building permit program for structures. This means the county itself does not issue building permits for construction projects. However, this does not exempt property owners from all permitting requirements, especially for properties in unincorporated areas. HVAC installations, like other mechanical work, are subject to state codes and may require permits from the State of Montana.
For properties in unincorporated areas of Granite County:
- Building Permits: Granite County does not require building permits for structures. However, a State of Montana building permit may be required for commercial buildings or multi-family structures.
- Mechanical/HVAC Permits: While Granite County does not issue mechanical permits, HVAC contractors are required to hold a valid state license. Mechanical permits, which cover heating, ventilation, and air conditioning systems, are generally required for work outside of cities that are certified to issue their own mechanical permits. In areas without local mechanical inspection programs, the absence of a local permit process does not eliminate applicable code standards. Property owners and contractors remain subject to adopted state codes.
- Zoning and Floodplain Permits: Properties within the Georgetown Lake Zoning District require a zoning permit before any construction. Properties located within a floodplain must obtain a floodplain permit.
- Septic Permits: All properties require a septic permit from the Tri-County Sanitarian before construction.
- Electrical and Plumbing Permits: Structures with electricity and plumbing require electrical and plumbing permits from the State of Montana.
It is crucial to contact the Granite County Planning & Zoning Department to confirm specific requirements for your project, as rules and fees can change.

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.
