Important: Have you checked with the Health Department on whether you will need a septic permit or evaluation? Even if you don’t think your project will affect your septic system, it’s best to check with the Health Department first so there are no surprises later. Septic permits must be issued before you can get any other permits. Call the department at 406-258-4990. You can read more on septic system evaluations in the Resources section.
