City-County zoning is determined through public processes and is intended to govern the use and development of land in Butte and Silver-Bow County. The primary purpose of zoning is to protect and promote the public health, safety and general welfare for people living and operating in Butte-Silver Bow. Zoning districts specify a category of uses and are applied by ordinance. Zoning district boundaries are shown geographically on the land use maps linked below.
