From the Wyoming guide
Wyoming has 9 counties without countywide zoning and 14 with zoning.38 The first counties without countywide zoning are Crook County, Fremont County, Johnson County, Big Horn County, Weston County, Converse County, Washakie County, Campbell County.3 The no-zoning county list provides the full comparison.3
The overlap matters: 7 counties have both no residential building-permit requirement and no countywide zoning, including Crook County, Fremont County, Johnson County, Weston County, Converse County, Washakie County, Goshen County.9 See the combined county list when both conditions matter to your search.9 Lack of countywide zoning does not remove Wyoming's septic authorization or subdivision framework; regulated land divisions still require county subdivision approval before sale, plat recording or subdivision construction.1015
