Sign Permit in Unincorporated Yellowstone County, Montana

Unincorporated Yellowstone County has no separate county sign code or county-run permitting office. Sign permits for property in the county's zoning jurisdictional area (the area within roughly 4.5 miles of the Billings city limits, per the county zoning code) are administered by the same joint City/County Planning Division (Planning and Community Services Department) that handles Billings' own sign permits, via the shared Citizen Access / CityView online portal. The Division's own published guidance states plainly: 'Sign Permits are required in the City of Billings and in the zoning areas around the City limits.' Signs are reviewed against the Billings Municipal Code Sign Regulations (Chapter 27, Zoning, Article 27-1400, previously codified as Article 27-700) and, for electronic message display (EMD) signs specifically, against a distinct Yellowstone County EMD Sign Regulations document the Planning Division has published for county-side EMD signs.

When you need this permit

  • A sign permit is required for all signs erected or attached on property or to a structure within the City of Billings AND the surrounding Yellowstone County zoning jurisdictional area -- not just inside Billings city limits
  • Confirm the property is within the joint zoning jurisdictional area (roughly 4.5 miles of the Billings city limits) using the County Zoning Map GIS tool or by calling the Planning Division at (406) 657-8247 -- land outside that boundary is not subject to this permit
  • All signs and their supporting structures must be placed on private property, outside the public right-of-way (limited exceptions exist for awning/sidewalk signs in Billings' Central Business District and East Billings Urban Renewal District, which do not apply to the unincorporated county)
  • Electronic message display (EMD) signs on county property are separately governed by a Yellowstone County EMD Sign Regulations document and require a Certification of Ownership - County EMD Signs form
  • Illuminated signs additionally require a separate electrical permit from the Building Division for the electrical installation/hookup (see this jurisdiction's Electrical Permit entry) -- the sign permit alone does not cover electrical work
  • Applications are submitted online through the Citizen Access / CityView Portal, selecting the 'Signs' project type

    Tips

    • There is no separate 'Yellowstone County Sign Code' -- the same joint City/County Planning Division, using the Billings Sign Regulations (plus a county-specific EMD sign addendum), administers sign permits for both the city and the surrounding unincorporated zoning jurisdiction.
    • Confirm your property actually falls within the joint zoning jurisdictional area before applying -- land further out in the county may not be subject to this permit at all.
    • An illuminated sign needs a separate electrical permit from the Building Division in addition to the sign permit itself.
    • Sign compliance is enforced by the Code Enforcement Division on a complaint basis, not through routine inspection.
