Tips
- All building inspections must be scheduled directly with the City of Whitefish Building Department at (406) 863-2410 or buildingdept@cityofwhitefish.gov, with a minimum of 24 hours' notice and the project address on hand — Columbia Falls does not perform its own inspections in-house despite being the certified/permitting jurisdiction.
- The Building Permit Application itself does not print a fee table; Building Permit Fee, Plan Review Fee, and Fire Prevention Program Fee amounts are calculated and filled in by the Building Department at time of submission.
- Plans must show 55 lb snow load, Seismic Zone D1, and 115 MPH wind design — these appear directly on the City's Building Permit Packet checklist.
- Townhome/duplex projects with a shared party wall require specific fire-rated common-wall drywall inspections (two separate inspections for a two-hour-rated single common wall, or inspections on both sides for two-layer assemblies) per the Required Inspections List.
