Granite County Plumbing Permit Requirements

Granite County, Montana, does not have its own building permit program for structures. However, plumbing permits are required and are issued by the State of Montana. All structures with electricity and plumbing require electrical and plumbing permits from the State of Montana. For more information, contact the State of Montana at 406-841-2056.

Montana has adopted the 2021 Uniform Plumbing Code (UPC) as its foundational technical reference for plumbing. This code is amended by the state and codified in the Montana Administrative Rules (ARM) Title 24, Chapter 301. The state plumbing program is administered by the Montana Department of Labor and Industry (DLI).

Properties in Unincorporated Areas

For properties in unincorporated areas of Granite County, plumbing permits are issued through the State of Montana's plumbing program. While Granite County itself does not issue building permits for structures, it does require zoning compliance permits for properties in the Georgetown Lake Zoning District and floodplain permits for properties within a floodplain. Additionally, all properties require a septic permit from the Tri-County Sanitarian before construction.

Homeowners performing their own plumbing installations for their personal use (not for speculation or rental) are exempt from obtaining a plumbing permit. However, farms and ranches, mines, mills, smelters, railroads, and public utilities are also exempt from state plumbing permit requirements.

All plumbing work must be performed or supervised by a licensed journeyman or master plumber in Montana. The service of a Montana licensed Master Plumber is required on all public/commercial buildings.
