Flathead County Plumbing Permit Requirements
Flathead County, Montana, does not administer its own building code program or require building permits for new construction or remodeling within the county. Consequently, the county does not issue certificates of occupancy. However, for properties located in unincorporated areas of Flathead County, plumbing permits and inspections are handled by the State of Montana Department of Labor and Industry. New residential construction may also require electrical and other mechanical permits from the state.
For specific guidance on plumbing permit requirements in unincorporated areas, it is recommended to contact the State of Montana Building Codes Bureau directly. They can clarify jurisdiction and specific requirements for your property.
Homeowners undertaking their own plumbing installations for their personal residence, which is not intended for speculation or rental, are generally exempt from obtaining a plumbing permit. However, farms, ranches, mines, mills, smelters, railroads, and public utilities are also exempt from state plumbing permit requirements.
For commercial or public buildings, a Montana licensed Master Plumber is required for plumbing work. All plumbing work must adhere to the Uniform Plumbing Code and state building codes.
