Tips
- Whitefish is DLI-certified for mechanical (M) permitting within city limits — permits are issued by the City, unlike a partially-certified city such as Havre where mechanical permits are mailed to the state Building Codes Bureau in Helena.
- The Trade Permit Application covers mechanical, electrical, and plumbing work on one shared form.
- reviewTimelineDays is null (hard-unpublished): the City of Whitefish publishes no review turnaround for mechanical/HVAC trade permits on its Building Permits / Inspections page, Planning & Building page, FAQ, fee schedule, or Citizen Portal, and City Code 10-1-4/10-1-1 sets no review-day period. Because Whitefish is DLI-certified for Mechanical (M), these permits are reviewed by the City itself and are not routed to the state DLI, so the state's 'three weeks' state-administered figure does not govern. No real governing figure was found after exhausting the city site, city code, and MT DLI. Contact Planning & Building at (406) 863-2410 for current review timelines.
