Tips
- Anaconda-Deer Lodge is NOT on Montana's certified-jurisdiction list for plumbing — every plumbing permit there is a STATE permit issued by the Building Codes Bureau, not the county Building Inspector.
- A water heater replacement is a flat $25 state fee (plus the standard $10 fixture/trap fee if the water heater is counted as a fixture per the application form) — confirm the exact line-item breakdown with the Building Codes Bureau at (406) 841-2056.
- Homeowners performing their own plumbing on their own owner-occupied, non-rental home are exempt from the state plumbing permit requirement.
- Apply online at https://aca-prod.accela.com/bcb/ or mail the paper application with payment to: Department of Labor & Industry, Building Codes Bureau, PO Box 200517, Helena, MT 59620-0517.
Frequently asked questions
- Does a water heater replacement need a permit in Anaconda-Deer Lodge?
- Yes, unless the homeowner exemption applies (owner performing the work themselves on their own owner-occupied, non-rental home). Otherwise, a State Plumbing Permit is required from the Montana Building Codes Bureau — $25 for each new water heater or replacement, per the state's published Application for Plumbing Permit fee schedule.
- Who issues plumbing permits in Anaconda-Deer Lodge — the county or the state?
- The State of Montana. The ADLC Building Inspector's own webpage confirms plumbing permitting and inspection are functions of the Montana Department of Labor and Industry, not the county, because Deer Lodge County is not a certified local government for plumbing.
