Tips
- Simple wall, window, and non-illuminated signs typically fall in the City's 'no plan review required' track (2-3 business days); ground signs over 7 ft or signs needing Special Sign Design Review ($2,104 base fee) can take substantially longer.
- Illuminated or digital/dynamic-display signs require a companion electrical permit in addition to the sign permit.
- A sign not installed within 180 days of permit issuance requires a new permit application.
- Three separate City fee lines can apply to a single sign depending on complexity: the Planning sign permit fee (by sign type), a Building Division 'Sign Review & Inspection' fee ($254, only if a building permit is triggered), and a Fire Prevention Bureau sign review fee ($110, only if fire-code clearance is required) — confirm with Development Services which apply to your specific sign.
- For sign code interpretation questions, contact the Zoning Desk at (406) 552-6625 or zoningdesk@ci.missoula.mt.us.
