Demolition · Lake County, Montana
Permit required
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 Planning Department before work begins.

Whether you are tearing down an old shed, removing a swimming pool, or executing a full structural demolition, local regulations require strict oversight. Tearing down structures involves managing hazardous waste and shutting off municipal utilities, which is why pulling a permit is almost always a mandatory first step.
With a population of around 32,561 residents, Lake County generally runs a more streamlined permitting process than major urban hubs.
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 Lake County
Regardless of the state permit rule above, Lake County still enforces property-line setbacks and local zoning for your Demolition. A permanent foundation or any electrical/plumbing hookup can also change what is required, so confirm with Planning Department 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.

Frequently Asked Questions
What happens if I build a Demolition without a permit in Lake County?
Building without authorization is considered a code violation. The local government can issue a Stop Work Order, forcing you to halt construction immediately. You may be subject to retroactive permit fees (often double the original cost), daily fines, or even a mandate to tear down the unpermitted work at your own expense.
Can a homeowner pull their own Demolition permit in Montana?
Yes. Montana generally allows property owners to act as their own general contractor under an Owner-Builder exemption. If you take this route, you assume full legal and financial liability and must ensure all work complies with the Montana State Building Code.
How much does a Demolition permit cost in Lake County?
Permit fees vary by jurisdiction and by your project's valuation, so Lake County does not publish a single fixed figure. Confirm the exact fee with the local building department before applying.
How long does it take to get a Demolition permit in Lake County?
Based on the size of Lake County, the typical processing time is 1 to 5 business days (Often over-the-counter). Times vary with the season and the building department application volume.
Where do I apply for a Demolition permit in Lake County?
You can apply through the Planning Department or online via the county permit portal. For questions, call (406) 883-7235.
