Montana, Beaverhead County Plumbing Permit Regulations and County Ordinances for Unincorporated Areas

Beaverhead County Building and Safety Jurisdiction

Beaverhead County does not have a certified local building code enforcement division. Therefore, building permits for new construction, alterations, additions, and repairs in unincorporated areas are issued by the Montana Building Codes Bureau at the state level. The county's Land Services department handles other regulations, including subdivision regulations, floodplain ordinances, zoning compliance, address assignment, and airport affected areas regulations. It is possible that work in unincorporated areas of Beaverhead County may require both a state building permit and county zoning/floodplain compliance.

Rules for Properties in Unincorporated Areas

For properties in unincorporated areas of Beaverhead County, the Montana Building Codes Bureau is responsible for issuing building permits. This includes permits for new construction, alterations, additions, and repairs. To obtain a state building permit, you will need to submit construction plans and a Building Permit/Plan Review Application to the Building Codes Program for review and approval. It's important to note that building permits must be issued before plumbing, mechanical, or electrical permits can be issued, and before work can commence. Additionally, county-level compliance with zoning and floodplain regulations may also be required.

Plumbing Permit Requirements in Montana

Plumbing permits in Montana are administered by the Montana Department of Labor and Industry (DLI) through its Building Codes Bureau. Plumbing permits and inspections are mandatory for most plumbing work to ensure compliance with the state's plumbing code. Generally, new construction, alterations, and remodels of plumbing systems require a permit. While some minor maintenance and repair work, such as clearing drain blockages or fixing minor fixture leaks, may be exempt, direct fixture replacements might require a permit depending on the jurisdiction. Licensed master plumbers are required to pull permits for residential work, and their service is mandatory for all public/commercial buildings. Homeowners may be exempt from obtaining a plumbing permit for work on their own owner-occupied single-family residence, provided they perform the work themselves and the residence is not for resale or rental. However, this homeowner exemption does not eliminate the requirement for inspection. Farms and ranches, mines, mills, smelters, railroads, and public utilities are generally exempt from state plumbing permit requirements.
