Montana Building Codes Program

Due to the evolving COVID-19 situation in Montana, all Montana Department of Labor & Industry offices are closed to the public to protect the health and safety of our clients and staff. Our services are available through remote delivery. Due to an increased load on phone lines statewide, our phones are not operational. We are available to assist customers through our online public portal at  EBIZ.MT.GOV (for Permits). For other services, please contact us via email at BUILDINGCODES@MT.GOV.

Currently, our inspectors are working remotely and available by cell phone or email and performing virtual inspections via video and picture review. In the case of critical inspections, our inspectors will be assessing the request and may, on a very limited basis, perform onsite inspections. Please contact the inspector in your area to discuss your needs. If you are unsure of who your inspector is or how to contact them, please email BUILDINGCODES@MT.GOV to request their contact information. Please include your location and the type of inspection required to ensure we provide the appropriate contact information.

The Building Codes Program (BC Programs part of the Commercial Measurements Bureau within the Montana Department of Labor & Industry’s Business Standards Division. The BC Program establishes and enforces statewide codes by issuing permits and performing inspections. The program includes inspection and permitting for Building Codes (building, plumbing, electrical, and mechanical), Elevator, and Boiler programs.. In addition, the program administers the Factory-Built Building and Underground Utility Protection Programs. Field inspection staff for the programs are positioned around the state to ensure adequate coverage for inspection and regulation of projects requiring a permit.

In Montana, cities, counties and towns have the option to enforce local building, electrical, plumbing, and mechanical codes, all or in part. These local building code enforcement programs must be certified by the BC Program. The remaining cities, counties and towns that have chosen not to enforce building codes, fall under the jurisdiction of the BC Program.

The Building Codes Program safeguards individuals from potential hazards that are inherent in the construction of new buildings, as well as the enlargement, relocation, repair, alteration, or change in use or occupancy of existing buildings. The program also ensures the safety of boilers and elevators by performing annual inspections. In addition, the program is responsible for adopting a uniform state building code, which is enforced statewide for residential and commercial buildings across Montana.
