Want a copy of the Hardin County plat book? It's a printed atlas of landownership, usually by township, useful for farms near Grassy Point. This Hardin County guide covers: how the atlas is organized, where to look for printed copies, and the free online map that stays current.
Getting started with the Hardin County plat book
Out toward Ada, plat books are commercial atlases, showing rural owners and tract lines, usually township by township.
Pulling up a parcel
Begin with the Hardin County Beacon site; it maps each tax parcel from Ada to Grant. When a rural tract has no street number, follow US Route 68 on the aerial and click the parcel itself, and that holds around Mount Victory too. On ground around Dola, the record panel usually lists the owner of record, assessed acreage, the parcel number and sometimes recent sales.
Getting answers from the right desk
Questions about value or the owner field for land near Dola belong with the County Auditor, which maintains the tax roll. Questions about what you can build around Kenton go to planning, building or health offices, town or county, depending on location.
Where to look for one
Not every county has a current edition, try the county extension office, recorder's office or library near Grassy Point.
Before you lean on the lines
For a tract near Dola, acreage on the record is an assessed number; only a licensed surveyor sets the real lines on the ground. Closer to Mount Victory, owner names and values update on a schedule, so a deed recorded last month can take weeks to appear.
Common uses
Farmers, hunters and appraisers near Foraker use plat books to see ownership across many tracts at once.
Land on the county line
Hardin County meets Allen County, Auglaize County, Hancock County, Logan County, and Marion County, and each of those keeps its own parcel map. A tract near the line by Kenton may show up across two assessors' files, so look at the adjacent map before you assume the acreage. With a lot near Grassy Point, our state page links each neighboring county map across Ohio.
How land is described here
Older tracts around Alger are often described by metes and bounds, listing bearings, distances and landmarks. Town lots near McGuffey are typically described by lot and block, making them easier to find. Write down the legal description for the tract near Ada before you request a deed or survey.
Recorded documents worth pulling
For a home near Grassy Point, the map is an index, not the title: deeds, subdivision plats and easements for parcels in the county sit with the County Recorder. For a parcel near Dunkirk, have ready the instrument number from the tax record and the lookup takes minutes.
On site with the map
Most viewers work in a phone browser, which helps when you're standing on land near Foraker, but coverage can be spotty out of town. A saved image of the lot near Kenton and its lines keeps working without signal.

The free online alternative
For current names, use the Hardin County Beacon site, across the county.
Not the same thing
On ground around Dola, don't confuse the atlas with a recorded subdivision plat: the recorded plat at the County Recorder is a legal document, while the atlas is a reference.
Places you'll see on the map
Kenton serves as the county seat, home to the main records offices. Other places on the map include Ada, Alger, Dunkirk, and Forest, where town lots give way to larger tracts. About 30,368 people call Hardin County home (Census estimate, 2023) spread over some 470 square miles. The county was organized in 1833, and some chains of title near Ada are long.

Not a survey. County GIS and tax parcel maps are assessment and planning layers. They are not a substitute for a recorded plat, deed, or licensed survey, especially for fences, setbacks, or boundary disputes.
