Ohio (OH) property records data
~4.4M residential parcels in Ohio on our national assessor and recorder file, with owner, mailing address, structure characteristics, values, sales and liens keyed to the parcel. Fill rates below are measured on the September 2026 snapshot, residential parcels as the denominator.
Field fill rates in Ohio
The share of residential parcels in Ohio on which each field is populated. Owner name, mailing address, lot size, assessed value and coordinates are filled on effectively every parcel nationally and are omitted. The structure fields are the ones that vary, because they come from county field cards that not every county publishes.

| Living area | ~95% | ~90% |
| Bedrooms | ~100% | ~100% |

Denominator: parcels with a residential land use code. Fill rates on all parcels, including vacant land and commercial, are lower; on parcels with a building they are higher and the denominator varies by state. We use residential throughout so states compare.
What the Ohio file is used for
- Loading the state into a warehouse or product under a bulk license
- Owner and mailing-address appends for Ohio addresses
- Insurance underwriting inputs where the structure fields are filled, with the roof field supplemented from permit history because Ohio counties publish it on ~30% of parcels
- Purchase, refinance and new-homeowner triggers from the recorder side of the file
Ohio sits near the national pattern: the basic characteristics are well covered and the structure codes are filled on a majority but not all parcels.
The other side of the Ohio market
Parcels are the housing stock; licensees are the people who transact it. The Ohio real estate license data page covers every agent and broker on the state register with matched contact data, and the Ohio license lookup checks a single license for free.
