Fire Sprinkler / Fire Alarm Permit in Darby, Montana
The Town of Darby publishes no local fire-sprinkler or fire-alarm permit process. Darby's Montana DLI trade certification covers Building (B), Plumbing (P), Mechanical (M), Electrical (E) and Swimming Pool (SP) only -- it does not include Fire Protection (FP), the category DLI uses for fire-suppression and sprinkler work -- and the Town's Building Permit Fee Schedule has no fire, sprinkler or alarm line item. Fire service is provided by the Darby Volunteer Fire Department under contract; reach them at (406) 821-3100 (non-emergency), 500 N. Main Street, to confirm what review your system needs.

When you need this permit
- No Darby-specific fire-sprinkler or fire-alarm permit requirements are published; contact the Town of Darby Building Department ((406) 821-3753) and the Darby Volunteer Fire Department (non-emergency (406) 821-3100) directly to confirm the current review pathway for a specific project
- Montana licenses fire-protection contractors/installers statewide through the DLI Fire Protection License Program (business and individual endorsements for selling, installing, and servicing fire protection systems), separate from any local plan-review or permitting step -- this governs who may perform the work, not who reviews/permits it locally
- Darby is not DLI-certified for the Fire Protection (FP) trade (its certification covers B, P, M, E, SP only), so fire-suppression plan review does not fall under the Town's own certified Building Department program the way Electrical, Plumbing, and Mechanical work does

Tips
- Darby holds DLI trade certification for Building, Plumbing, Mechanical, Electrical, and Swimming Pool only -- not Fire Protection (FP) -- so, unlike those five trades, fire-sprinkler/alarm work is not confirmed to be reviewed and inspected directly by the Town.
- Before starting a fire-sprinkler or fire-alarm project in Darby, confirm the current reviewing authority directly with the Town of Darby Building Department ((406) 821-3753) and the Darby Volunteer Fire Department (non-emergency (406) 821-3100) -- this record could not independently verify whether that authority is the Town, the fire department, or the Montana State Fire Marshal's Office.
- The Darby Volunteer Fire Department's own website (darbyfire.com) was unreachable (404) as of the last verification; use the phone contact above instead.
