Steps to Start your Project:
STEP 1. Do your research! Questions to ask while you’re researching your project: How is the property zoned? Do I need an address? Should I do the work or hire a contractor? Do I have an HOA with restrictions on what I can build? Am I in the floodplain? Do I need any other permits besides building? Click here for a list of commonly asked questions.
Contact Community & Planning Services (406-258-4642) for zoning or land use applicable regulations, the Health Department (406-258-4990) for applicable well/septic regulations, or the Building Department (406-258-3701) for building construction code questions.
STEP 2. Apply for a Building Permit at Missoula Co. Public Works or Online. Please See above Required Documentation for Submittal.
STEP 3. Wait. Several departments will be reviewing your permit electronically and simultaneously. This may include Floodplain, Air Quality, Fire, Well & Septic, etc. You may receive a call from a reviewer needing more information about your project. The average issuance for the permit package is 10 business days.
STEP 4. You will be contacted by a Permit Specialist once your permit is ready to be issued. The Building Permit fee must be paid upon pick up, then the inspection card and stamped drawings can be released. This is also the time to apply for any trade permits, i.e.: Electrical, Mechanical and Plumbing permits. These permits have separate fees that are dependent on the scope of work.
STEP 5. CONSTRUCT! Please call for the applicable inspections on your inspection card 24 hours ahead of time.
*Please call 406-258-3701 to speak to a Permit Specialist or Inspector if you have any further questions about these steps.
