Judith Basin County Plumbing Permit Requirements
For properties located in unincorporated areas of Judith Basin County, Montana, plumbing permit requirements fall under the jurisdiction of the state's Building Codes Bureau, as the county itself does not issue building permits for construction in these areas. The state has adopted the 2021 Uniform Plumbing Code (UPC) as its foundational technical reference for plumbing.
Plumbing permits are generally required for all new residential plumbing installations, replacements of systems or major components, and alterations that change the configuration of supply or drainage, waste, and vent (DWV) systems. Inspections are a mandatory part of the process, typically occurring at the rough-in stage (before walls are closed), underground stage (before backfill), and final inspection before occupancy.
While homeowners may be exempt from needing a plumbing license to perform work on their own owner-occupied single-family residences, a permit is still required, and the work must pass inspection. This exemption does not apply to rental properties or homes built for speculation or resale. Farms and ranches, mines, mills, smelters, railroads, and public utilities are exempt from state plumbing permit requirements.
The cost of a plumbing permit is typically calculated as a percentage of the total building valuation, which includes all labor and materials.
Rules for Properties in Unincorporated Areas
In unincorporated Judith Basin County, the Montana Building Codes Program, part of the Department of Labor & Industry, is the authority having jurisdiction for building and plumbing permits. The process generally involves submitting a permit application and construction plans for review by the Building Codes Program. Once plans are approved and fees are paid, a permit is issued. Construction can then commence, with required inspections scheduled throughout the process.
The state of Montana has adopted the 2021 edition of the Uniform Plumbing Code (UPC). This code, along with any state-specific amendments, governs plumbing installations. While local jurisdictions can adopt their own codes, for unincorporated areas, the state's adopted codes and regulations apply.
Exemptions for building permits in unincorporated areas include single-family residences (though they still require electrical and plumbing permits), agricultural buildings not used for habitation or commercial purposes, and small storage sheds under 200 square feet. Minor repairs and maintenance not involving structural changes are also generally exempt.
