Permit Requirements for Whitlash, Montana

For Plumbing projects in Whitlash, determining the correct permitting authority depends on whether the project site is located within the incorporated city limits or in an unincorporated area of Liberty County.

Liberty County Building & Safety Divisions

Liberty County is responsible for issuing building permits for properties located in unincorporated areas of the county. The Building Services Division reviews construction plans, issues permits, and conducts inspections. For unincorporated areas outside of Chester city limits, the Liberty County Government/Clerk and Recorder's office is the permit authority. The Clerk and Recorder's office can be contacted at (406) 759-5365 or [email protected].

Rules for Properties in Unincorporated Areas

In unincorporated Liberty County, Montana, a building permit is generally required for most construction, additions, alterations, or repairs. However, certain types of work may be exempt. Residential buildings with fewer than four dwelling units are exempt from state building permits, but plumbing and electrical permits are still required. Other exemptions may include farm and ranch buildings not used for human occupancy, private residential garages used solely for vehicle storage, and minor repairs and maintenance.

Plumbing permits are separate from building permits in Montana. A licensed master plumber or plumbing contractor is required to pull permits for residential work. Journeyman plumbers can perform work under a master's supervision. Commercial projects require a standalone plumbing permit issued by the Montana Department of Labor and Industry (DLI) Building Codes Bureau or an approved local jurisdiction. Plumbing work cannot commence without the specific plumbing permit.

Homeowners in Montana are exempt from needing a plumbing permit for work on their own single-family residence if they are performing the work themselves and the residence is for their personal use and not for speculation or rental. However, this homeowner exemption does not eliminate the requirement for a permit and subsequent inspection.
