What a Butler County property record shows—and what each field means
| Record field | What it means | What to check |
|---|---|---|
| Parcel number | The county identifier assigned to the parcel. | Use it across Auditor, GIS, Treasurer and official forms. |
| Owner name | The ownership name currently carried on the Auditor record. | Compare it with the most recent recorded deed when ownership looks outdated. |
| Property address | The physical location connected with the parcel. | Do not confuse it with the owner’s mailing address. |
| Legal description | The recorded description used to identify the land. | Use a deed, plat and survey for legal-boundary decisions. |
| Land value | The appraised value assigned to the land portion. | Review lot size, location, use and land classification. |
| Building value | The appraised value assigned to structures and improvements. | Verify living area, basement, quality, condition and improvements. |
| Appraised value | The Auditor’s full property value used in the tax process. | This is the value normally challenged through the Board of Revision. |
| Assessed value | Generally 35% of appraised value for Ohio real property. | The effective tax rate is applied to assessed value, subject to reductions and credits. |
| Tax district | The combination of taxing authorities affecting the parcel. | Nearby properties may have different rates when district boundaries differ. |
| Transfers | Reported ownership changes and sale information. | A family transfer, foreclosure or entity change may not represent market value. |
| Current Tax Distribution | A levy-level breakdown showing where current tax dollars are distributed. | Use it to understand schools, local governments and specific levies. |
| Board of Revision tab | Shows complaint information connected with the parcel. | Use it to follow a filed case and later result information. |
How to use Butler County GIS maps without treating them as a legal survey
The official GIS viewer helps locate parcels, compare neighboring properties, review map context and connect a parcel shape with the Auditor record.
Parcel location, nearby parcels, aerial context and general public-record research.
A displayed parcel line should not be used alone to install a fence or settle ownership.
Match the map with the deed, legal description, Recorder record and title work.
Butler County 2026 property reappraisal: what changed and what it does not mean
The 19% figure is a countywide median, not a guaranteed change for every home. Individual results depend on land size, grade or quality, condition, living area, basement living area, improvements and local market activity.
The new values apply to tax year 2026 and will be used for bills payable in 2027.
Ohio generally assesses real property at 35% of appraised market value.
Compare the value with a recent purchase, refinance appraisal and similar recent market sales.
Selected residential and agricultural median changes
| Jurisdiction | Median change | How to use this number |
|---|---|---|
| Butler County overall | 19% | Countywide context only—not a parcel-specific value. |
| Lemon Township | 39% | Compare your record with its own characteristics and market evidence. |
| New Miami | 32% | Do not assume every property increased by the median. |
| Millville | 31% | Review the individual parcel record and recent sales. |
| Middletown | 30% | Focus on the subject property’s value, condition and size. |
| Hamilton | 27% | A jurisdiction average is not Board of Revision evidence by itself. |
| Liberty Township | 18% | Compare similar recent arm’s-length sales. |
| West Chester Township | 18% | Check improvements, lot size and building characteristics. |
| Fairfield Township | 15% | Separate value change from new levy impact. |
| Oxford and Monroe | 15% | Use parcel-specific evidence for any formal appeal. |
