Fallon County Plumbing Permit Requirements

Fallon County, Montana, issues building permits for properties located in unincorporated areas of the county. If your property is within an incorporated city, that city's building department will handle your permits. Montana has adopted the 2021 Uniform Plumbing Code, along with other International Codes for building, residential, fuel gas, and electrical work. The state plans to adopt the 2024 ICC codes in mid-2026.

A state building permit is required before plumbing, mechanical, or electrical permits can be issued and work can commence. To obtain a state building permit, construction plans and a Building Permit/Plan Review Application must be submitted to the Montana Building Codes Bureau for review and approval. This process typically takes about three weeks for plan review.

Once plan review comments are addressed and fees are paid, the building permit is issued. It is then the responsibility of the permit holder to schedule required inspections, including plumbing inspections, and ensure access for them. All inspections must pass before a certificate of occupancy is issued.

While Montana does not require state-level contractor licenses for independent contractors without employees, contractors with employees, corporations, or manager-managed LLCs must register with the state. Owner-builders have minimal restrictions and can obtain permits for their own construction without a contractor license.

For specific local zoning or planning requirements, it is advisable to contact the Fallon County Planning Department. The application process involves preparing construction documents, completing the Building Permit/Plan Review Application form, and submitting it to the Montana Building Codes Bureau via EBIZ.MT.GOV or mail.

Rules for Properties in Unincorporated Areas

Fallon County is the permit authority for properties in its unincorporated areas. For properties within incorporated cities like Baker or Plevna, those respective city building departments handle permit applications. The state building permit is a prerequisite for obtaining plumbing permits in Montana.
