The Franklin County Auditor's office is responsible for maintaining and updating all records that are related to real estate, including establishing values for every real estate parcel in the county. A full reappraisal of all properties in Franklin County is completed every six years, with a triennial update on the third-year midpoint of the six-year cycle to update values to reflect the current real estate market.


ANNUAL REVIEW: Each year, the appraisal division reviews any property which has changed since the previous year. Most often the change is due to a sale/transfer, new construction, a change in the physical size or shape of the land, a demolition, or damage to the property. Final values are determined by the Ohio Department of Taxation and per Ohio Revised Code.


2023 REAPPRAISAL: The next reappraisal for Franklin County properties will occur in 2023. It takes approximately two and a half years to complete a reappraisal, during which time appraisers will perform exterior reviews of every property in the county to accurately assess values.
