Big Horn County, Montana Plumbing Permit Requirements
For properties located in unincorporated areas of Big Horn County, Montana, plumbing permit requirements fall under the purview of the state's Building Codes Program, as the county has not adopted its own certified building code enforcement program. This means that private property owners in these areas must adhere to state-level regulations. It is important to note that Crow Reservation lands are excluded from both county and state jurisdiction.
A state building permit is required before plumbing, mechanical, or electrical permits can be issued and work can commence. The application process involves submitting construction plans and a Building Permit/Plan Review Application to the Montana Building Codes Program for review and approval. Once the plan review comments are addressed and fees are paid, the building permit is issued. Subsequently, plumbing permits can be obtained.
The state of Montana has adopted the Uniform Plumbing Code, 2021 Edition, which is effective as of June 11, 2022. An application for a plumbing permit requires accurate location and owner information, and fees are typically based on the number of fixtures.
While Big Horn County does not have countywide zoning, it does have localized Airport Protection Zoning. For construction projects in rural Big Horn County, it is noted that there are no building codes at the county level. However, contractors must follow all applicable electrical and fire protection codes. It is recommended to use national building code standards for any improvement projects, especially if the property is intended for future sale.
Before starting any construction or development, it is advisable to determine if local zoning regulations exist, as cities, towns, and counties in Montana may adopt zoning regulations that could require additional permits.
