Three departments issue permits related to home-improvement projects:
- Public Works Building Division
- Missoula City-County Health Department
- Planning, Development & Sustainability Department
The specifics of your project will determine what department you start with.
- Septic/well installation: If your project involves your septic system or well, you will start the application process with the Health Department. A septic permit must be finalized before the county can issue any building or construction permits. Call the Health Department at 406-258-4990 or email [email protected].
- Projects impacting septic systems or wells: Even if you don’t think your project requires changes to your septic system or well, you still need to contact the Health Department. Many projects that do not involve new installation or connection require a Health Department evaluation. For example, if you are building a detached garage, the Health Department will make sure you do not build it on top of your drainfield. Also, septic systems are designed to accommodate a maximum number of bedrooms. Interior remodels that include new bedrooms require septic system review.
- For complex projects, it’s best to start with the Health Department to lessen the chance of surprises later. Call the Health Department at 406-258-4990 or email [email protected].
- Most other projects: Other permit applications begin with the Building Division. Once submitted, either online or in person, you application will go through the intake process to insure it meet the requirements. If intake process is a success, then your project will be routed to the different permitting departments and reviewed simultaneously. You may receive a call from a reviewer needing more information about your project.
