Buying Land in Harrison County, Ohio

Zoning: four confirmed townships, the rest unclear

This research pass found no evidence that Harrison County itself has adopted county rural zoning under ORC Chapter 303. What is confirmed is zoning in four specific townships under ORC Chapter 519: Archer, Freeport, Moorefield, and North Townships, each administering its own zoning independently. The Village of Cadiz, the county seat, separately maintains its own municipal zoning within its corporate limits, entirely apart from any township's rules.

For the county's remaining townships, this research pass did not find confirmation either way -- meaning a specific parcel could sit in an unzoned township with no local land-use restrictions beyond state and federal law, or in a township whose own zoning simply wasn't surfaced in available sources. Given how directly this can affect what you can build, subdivide, or site on a parcel, confirm zoning status directly with the specific township trustees before making any assumptions, especially in a county where active oil-and-gas development (below) makes surface-use questions more consequential than in a purely agricultural county.

Oil and gas: core Utica shale territory, with a current landowner dispute

Harrison County sits within the roughly five-county core of Ohio's Utica/Point Pleasant shale oil play, alongside Columbiana, Guernsey, Carroll, and Noble Counties -- together estimated to account for about 95% of the state's shale oil production. Ohio's overall Utica oil output hit a record 48 million barrels in 2025, a 39% increase year-over-year, though more recent reporting notes that newer wells in the play's northern tier (Columbiana and Mahoning Counties) are gaining relative share even as Harrison and Carroll remain established, major producers rather than a declining afterthought.

That activity isn't just historical background: in 2026, Harrison County landowner Ron Ott publicly disputed EOG Resources' handling of what's known as the Stout lease, covering 72 acres in Washington Township, alleging EOG improperly claimed mineral rights, damaged wells, and shorted him on royalties after acquiring the lease through a 2022 assignment from a prior operator, Pin Oak. Follow-up reporting frames the dispute as a more nuanced lease-assignment disagreement than the "theft" framing suggests, but it's a real, current, named example of exactly the kind of severed-mineral and lease-assignment complexity a Harrison County land buyer should expect to encounter.

Recreation: two of the region's largest lakes

Harrison County is also home to two of the larger lakes in the Muskingum Watershed Conservancy District's reservoir system. Tappan Lake covers 2,350 surface acres with roughly 5,000 surrounding acres of park land, a 299-horsepower limit, and Tappan Lake Park's 600 campsites, rental cabins, public beach, and boat launch facilities. Clendening Lake, at 1,800 acres with 43 miles of shoreline and a 10-horsepower limit, is described as the largest primitive (undeveloped) lake in Ohio, known for bass fishing and relative solitude compared to more developed lakes. Together with a portion of Piedmont Lake, these provide more than 4,200 acres of public recreational water in the county -- a real factor worth weighing for anyone considering recreational, cabin, or hunting-adjacent land here.

Septic and other departments to know

For a household sewage treatment system or well, the Harrison County Health Department (538 N. Main St., Suite A, Cadiz; (740) 942-2616, option 2) administers septic and well permitting countywide, including permits for lots under three acres, and registers sewage-system installers annually. No separate city health district was identified for Cadiz or any other Harrison County municipality.

The Harrison County Auditor and Recorder, both based in Cadiz, hold property, deed, and easement records for any parcel in the county -- particularly worth checking given the county's active oil-and-gas leasing history, since recorded leases, pipeline easements, and well-access agreements are common encumbrances on land here even where the surface itself looks like ordinary farmland or woodland.
