Step 3 - Prepare to Apply

Graphic arrow showing step 3, Prepare.
Make sure you have all required documents & plans BEFORE you apply for your permits online.

Now that you’ve defined your project and reviewed the types of permits you may need, it’s time to assemble the documentation you’ll need to apply. Below, you’ll find detailed checklists of what you need for common permits, as well as document examples.

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.

Application Checklists

Different permits involve different documentation requirements. Be sure to carefully review the documentation required for each permit you’ll need.
