Land questions in Harrison County start in the same place: the official parcel map. Here's how to use the Harrison County parcel map to find owners, acreage and boundary lines, and where it falls short.
Keep reading for the viewer link, how to search it, what the parcel data means, and how deeds and plats back it up in Harrison County.
Opening the Harrison County parcel viewer
Harrison County doesn't run its own public parcel site. The free option is the statewide Ohio Statewide Parcels layer in ArcGIS Map Viewer, which includes the county's parcels. Try the search box with a Cadiz street address first; for open land near East Cadiz, it's faster to pan and click. If the map ever goes missing, check the Harrison County, Ohio listing on Platbookmapper for the new address.
Behind the map: land records in Harrison County
Behind each Harrison County parcel is an assessment by the county auditor and a deed recorded with the county. In Ohio the county auditor, not an assessor, appraises real estate, so Harrison County values come from the auditor's office on a six-year reappraisal cycle with an update in year three. Copy the parcel ID and legal description before you call or visit; recording staff can find a Harrison County document much faster with them.
Towns, terrain and land across Harrison County
On the map, Cadiz anchors the county as its seat, with Adena, Bowerston, Deersville, and Freeport spread around it. Crossroads communities such as Tippecanoe, Brownsville, and Conotton have their own small clusters of lots. Harrison County was created in 1813 and takes its name from William Henry Harrison. For scale: roughly 402 square miles of land and an estimated 14,159 residents as of 2023, per the Census Bureau. Zoom out from Cadiz and the lots turn into fields and timber quickly; a few acreage homesites break up the larger tracts.
Who's clicking on Harrison County parcels
Small-farm and homestead buyers looking around East Cadiz compare tract sizes and shapes on the map before calling a listing agent. Unlisted land near Adena sometimes turns up this way: an empty parcel, an absentee owner, and a polite letter. A hunter driving the back roads near East Cadiz can match a promising woodlot to an owner name in seconds.
Using the Harrison County parcel map to find vacant land
A practical way to find vacant parcels near Adena:
- Follow the roads out of Deersville with aerials on and mark every tract without a rooftop.
- A tax bill mailed far from East Cadiz usually means an absentee owner, so note the mailing address on each record.
- Check that the tract touches a public road; a landlocked lot near Adena can be hard to finance and build on.
- Size up price by comparing a few similar tracts around Adena on the assessment records.
- For a tract near Deersville, confirm zoning, septic suitability and flood status before you make an offer.

Are the Harrison County property lines accurate?
Zoom in far enough on a lot in Freeport and you may notice lines crossing driveways or splitting sheds, a normal quirk of tax mapping. Depending on where in Ohio a tract sits, the deed may use a grid or metes and bounds; around Freeport, check the legal description to see which. For rural ground near East Cadiz, a recorded survey or a new one is the only reliable source for the true line.
Two things the map won't tell you
A lot in Bowerston that sold last month may still show the previous owner on the map. Treat Harrison County acreage figures as estimates until a survey confirms them.
