From the Missouri guide
Missouri has 54 counties without countywide zoning, including Texas County, Bollinger County, Dallas County.
Missouri has 54 counties without countywide zoning, including Texas County, Bollinger County, Dallas County3. County zoning is present in 29 counties, and we could not confirm the zoning answer for 32 counties8. Missouri county zoning authority applies to unincorporated territory; an address inside city limits needs the city's answer4.
The no-zoning list identifies counties without countywide zoning, while the no-building-permit and no-zoning list narrows the overlap to 50 counties3,9. A no-zoning answer does not remove Missouri septic approval or floodplain development requirements, so ask the septic authority and community floodplain administrator about the parcel before choosing a house site5,12.
