Permit required
Do you need a permit for Pool Construction in Treasure County?
In Montana, a Pool Construction requires a building permit.
Any pool more than 24 inches deep requires a permit and a compliant safety barrier at least 48 inches high with self-closing, self-latching gates (IRC R326 / ISPSC). Prefabricated pools under 24 inches deep are exempt. Plans are reviewed under the Local option code (IRC 2021); apply through Treasure County Planning Board before work begins.

With a growing population of around 732 residents, Treasure County maintains a relatively streamlined permitting process compared to major urban hubs. Processing typically takes 1 to 3 weeks.
Code Compliance & Inspections
Because of severe winter weather in Montana, any exterior structures or footings must be set below the local frost line to prevent shifting, as mandated by the Montana State Building Code.
Local Zoning & Setbacks in Treasure County
Regardless of the state permit rule above, Treasure County still enforces property-line setbacks and local zoning for your Pool Construction. A permanent foundation or any electrical/plumbing hookup can also change what is required, so confirm with Treasure County Planning Board before building.
Zoning & Cost Factors
Montana law allows for citizen-initiated zoning districts, meaning neighbors can band together to create custom zoning regulations in otherwise unzoned rural areas. Fortunately, Montana maintains relatively builder-friendly regulations, keeping base permit fees competitive.
