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.
