Buying Land in Union County, Kentucky

Grain country built on the Western Kentucky Coal Field

Union County's land base is dominated by large-scale row-crop agriculture -- corn, soybeans, and wheat spread across the flat to gently rolling terrain typical of far-western Kentucky. That farming economy sits directly on top of the Western Kentucky Coal Field, a coal-bearing region that has produced coal through both underground and surface (strip) mining for well over a century, historically making Union County one of the state's more significant coal producers even as agriculture remained the dominant surface land use throughout.

That overlap between cropland and coal country is the county's genuinely distinctive feature for a land buyer, and it's worth taking seriously rather than treating as ancient history: because coal companies acquired mineral rights across much of this region historically -- often through deeds that separated the coal, oil, and gas from the surface estate -- a Union County parcel can have a clean surface title and a separately owned mineral estate underneath it, or an unclear chain of title on exactly what was severed decades ago. The state hub covers how Kentucky's broad form deed history and its 1988 constitutional amendment changed what a mineral owner can do without the surface owner's consent; what matters locally is simply confirming, through a full title search at the Union County Clerk's office, whether a specific parcel's mineral rights were ever severed before you rely on surface ownership alone.

The Ohio River edge and general due diligence

Union County's northern boundary runs along the Ohio River, and bottomland near the river can carry real agricultural value from periodic natural flooding and rich soil, while also carrying real flood-zone exposure that inland farmland in the county doesn't share. Confirm FEMA flood-zone status directly for any parcel near the river rather than assuming it from general proximity, and factor any levee or drainage-district obligations into your evaluation if the parcel sits in a managed bottomland area.

Zoning and septic: confirm with the county and the district health department

This page did not confirm whether Union County has adopted a countywide zoning ordinance under Kentucky's optional KRS Chapter 100 framework -- confirm directly with the Union County Judge-Executive's office or planning commission before assuming either way. Septic permitting runs through the multi-county Green River District Health Department, based in Owensboro and also serving Daviess, Hancock, Henderson, McLean, Ohio, and Webster counties, following the site-evaluation, perc test, and permit sequence described in our national guides.
