Mineral County Plumbing Permit Requirements
Mineral County, Montana, handles building permits for properties located in unincorporated areas. For properties within incorporated cities, the respective city's building department is responsible for permit issuance. The county's Building Department requires a completed application, scaled technical plans (including plumbing plans for new construction, additions, remodels, and new construction), and supporting documentation such as proof of ownership and contractor licensing.
For plumbing permits specifically, a separate application is required for each building or structure, with exceptions for townhouses or commercial tenant spaces where each unit needs a permit. A Land Use permit may be required prior to the issuance of a plumbing permit. All plumbing work must adhere to the Montana Plumbing Code, which is based on the Uniform Plumbing Code (UPC) with state amendments. Licensed Montana master plumbers or plumbing contractors are generally required to pull permits for residential work.
Homeowners performing their own plumbing installations for their personal residence (not for speculation or rental) may be exempt from obtaining a permit. However, specific exemptions for farms, ranches, mines, mills, smelters, railroads, and public utilities also exist at the state level.
It is crucial to note that plumbing inspections are required before covering any plumbing work. The scope of residential plumbing requirements includes all plumbing within a structure's footprint and connections to water and sewer systems, whether public or private.
Rules for Properties in Unincorporated Areas
Mineral County issues building permits exclusively for properties situated in unincorporated areas of the county. If your property is located within an incorporated city, you must contact that city's building department for permit requirements. The county's Building Department requires a comprehensive application package for all new construction, structural alterations, and major renovations in unincorporated areas. This includes completed application forms, scaled technical plans (site plans, architectural drawings, and specific plans for electrical, plumbing, and HVAC), and supporting documentation like proof of ownership and contractor licensing.
For projects involving septic systems or wells in unincorporated areas, coordination with the Environmental Health and Planning Department is necessary. This may involve site evaluations and obtaining permits for On-site Wastewater Treatment Systems (OWTS) before building permits are issued.
