Full Breakdown
Montana counties may zone unincorporated land under MCA Title 76, Chapter 2, Part 2 (MCA 76-2-201 et seq.). Yellowstone County administers zoning in adopted districts, including the Laurel-Yellowstone County Planning jurisdiction (about one mile beyond Laurel), where the Board of Commissioners handles zoning outside the city. In those districts, home occupations are an accessory use permitted in residential zones as long as the activity remains incidental to use as a dwelling. Where no zoning district has been adopted over a rural parcel, the county sets no home-business standard, though state licensing (for food, childcare, etc.) still applies. Inside Billings or Laurel, that city's zoning code controls.
Violations & Fines
In a zoning district, operating a home business that exceeds the incidental-use limits can trigger a zoning violation, cease-and-desist notice, and revocation of any home occupation permit.
