2023 Property Value Update
Every three years, the County Auditor is required by the State of Ohio to reappraise all property in the County.
Our office completed a full reappraisal of property values in 2020 and is scheduled to complete a triennial update in 2023. These new values will impact the property taxes that you pay starting in 2024.
Notice for new property values will be posted when they are available.
The Auditor’s office will conduct informal review sessions-once those dates have been established, it will be posted on our website.
Check back for more information regarding informal reviews.
The window to file a formal property value appeal with the Board of Revision opens on January 1, 2024 and lasts until March 31, 2024.
