The City of Billings operates its own independent building and permitting department for properties within city limits. Yellowstone County handles permitting and zoning for all unincorporated areas of the county. Development in flood-prone areas along the Yellowstone River requires additional floodplain development permits.
The county enforces specific subdivision regulations and septic system permitting requirements for all properties located outside of municipal sewer service areas.
Cómo encaja con el estado
La autoridad estatal aquí es Montana Department of Labor and Industry. El expediente del condado no la reemplaza — añade la oficina de permisos, las reglas locales y el camino real de presentación.
