Mechanical / HVAC Permit (State-Issued) in Livingston, Montana
Required for mechanical/HVAC work anywhere in Livingston (city limits) and Park County, including furnaces, gas piping, ventilation, and cooling equipment. Because Livingston is NOT mechanically-certified, this permit is issued directly by the Montana Department of Labor & Industry Building Codes Bureau (Helena) under the 2021 International Mechanical Code — not the city.

Tips
- Mechanical permits for Livingston addresses are issued by the STATE Building Codes Bureau in Helena, not the city — mail applications and payment to PO Box 200517, Helena, MT 59620-0517, or apply online at ebiz.mt.gov.
- A $9,460 furnace project would cost $48 (first $1,000) + 9 x $14 (nine additional $1,000 fractions up to $9,000) = $174.00 total, per the state's own example.
- Boiler installations use a separate Boiler Permit form, not this Mechanical Permit application.
