Teton County, Montana Plumbing Permit Requirements
Teton County, Montana, handles building permits for properties located in unincorporated areas through its Planning Department. For properties within incorporated cities, the respective city's building department is responsible for permits. Plumbing work generally requires a permit, especially for new installations or alterations that extend, reroute, or replace supply lines. Licensed journeyman or master plumbers must perform or directly supervise all water supply plumbing work.
Montana state plumbing standards adopt the Uniform Plumbing Code (UPC) with state-specific amendments. These standards cover the design, materials, installation, and inspection of potable water distribution systems. Rough-in water supply lines must be pressure-tested before being concealed, and a final inspection is required to ensure compliance with fixture connections, pressure regulation, and backflow prevention.
For projects in unincorporated Teton County, a building permit is required for new structures, substantial additions, structural modifications, changes of use, demolition, and electrical, plumbing, and mechanical work. The permit application process involves contacting the Teton County Planning Department to determine jurisdiction and requirements. If the work is state-enforced, the application is submitted through EBIZ.MT.GOV. Complete construction documents, including plans and specifications, are necessary. Fees are typically calculated as 1-2% of the estimated building valuation.
Certain exemptions from building permits exist for unincorporated Teton County, including farm and ranch buildings without residential use, private storage buildings under owner's use (typically under 200 sq ft), private garages for owner's use, mining-related structures, petroleum refineries, and pulp and paper mills (excluding office/shop buildings). Residential buildings with fewer than five dwelling units are also exempt, excluding hotels.
Plumbing permits are generally required for any plumbing work that exceeds minor repairs or maintenance. Homeowners performing plumbing work on their own single-family dwelling, which they intend to reside in and not for speculation or rental, may be exempt from needing a plumbing permit. Farms and ranches with individual water supply or sewage disposal systems not connected to public utilities, as well as mines, mills, smelters, railroads, and public utilities, are also exempt from state plumbing permit requirements.
Inspections are a crucial part of the process. A 24-hour advance notice is required to schedule inspections, which typically include underground rough-in, framing and trade rough-in (before concealment), insulation, and a final inspection.
