Which codes and exemptions should I review?
Building codes in Flathead County are administered by Montana’s state program. The current 2026 code set is the 2021 International Building Code, 2021 International Residential Code, 2021 International Existing Building Code, 2021 International Mechanical Code, 2021 International Fuel Gas Code, 2021 International Energy Conservation Code, 2021 Uniform Plumbing Code, 2020 National Electrical Code, 2021 International Swimming Pool and Spa Code, and 2021 Wildland-Urban Interface Code, as amended by ARM Title 24, Chapter 301. Flathead County says county building permits are not required in unincorporated areas because it has no county building department. State exemptions generally include farm/ranch buildings, mine buildings, certain industrial facilities, residential buildings with fewer than five dwelling units unless transient, and owner-used private garages/storage buildings. County site-plan review is still required in BS, BR-4, HO, I-1H, and certain WV zoning districts.
