Do you need a permit for Demolition in Sanders County?
In Montana, demolishing a structure requires a permit.
Demolishing a building, or any structure with utilities or a foundation, requires a demolition permit, plus utility disconnects and often an asbestos check before work begins. Very small accessory structures such as a shed under 200 sq ft with no utilities may be exempt; confirm locally. Plans are reviewed under the Local option code (IRC 2021); apply through Sanders County Info Desk before work begins.
