State guidance for Montana
For slab leak repair in Montana, prepare foundation type, buried-line route, access, finished-surface restoration, and reroute options. Confirm the inspected scope, credentials, permits, inspections, exclusions, and restoration responsibility before authorizing work.
Credential verification
Plumbing in Montana is regulated by the Montana Board of Plumbers, part of the Department of Labor & Industry's Business Standards Division, under Montana Code Annotated Title 37. For most plumbing work, hire a state-licensed plumber and confirm the credential through the state's online licensee lookup.
The Board issues Journeyman and Master Plumber licenses (plus a Medical Gas endorsement), with apprentices working under licensed plumbers. Licenses renew annually, so it is reasonable to ask a plumber for their current Journeyman or Master license and verify it before work begins.
Permits and inspections
Montana uses a dual enforcement system: in cities and counties with a certified local building department, that office administers plumbing permits and inspections, and elsewhere the Montana Department of Labor & Industry's Building Codes Bureau is the authority having jurisdiction. Owner-occupants may be able to pull a homeowner permit and do their own work on a primary residence, but the work still requires a permit and inspection. Always check with your local building department — or the state Building Codes Bureau — first.
