Message regarding Real Estate Valuation and Assessment of Property Tax and this years Triennial Update

Ohio real property tax is the oldest tax in the state. Since 1825, it has been an “ad valorem tax”—meaning a tax based on the value of the real estate. By statute, the county auditor must appraise and value real property in each county. See Ohio Revised Code, Chapter 5715.

The process of valuing real estate in each county is conducted on a mass scale. As a result, most properties are only visually inspected from the exterior, and interior inspections are rare. There are simply too many properties in each county to conduct a detailed inspection of each one. In fact, in Ross County, Ohio alone, there are more than 45,000 parcels that all need to be appraised and valued by the Ross County Auditor.

Sexennial Appraisals and Triennial Update

The Tax Commissioner is charged with the duty of ordering all real property in each county to be appraised once every six years. This is usually referred to as the sexennial appraisal. R.C. 5715.33.

In addition to the sexennial appraisal, values are adjusted by the county auditor in the third year between the sexennial appraisals. R.C. 5715.24. This interim adjustment is usually referred to as the triennial update. The triennial update is a statistical analysis of the sales that have occurred in the prior three years. Property values are adjusted upwards or downwards based on a percentage calculated for each marketing neighborhood.

Each county conducts its sexennial appraisal and triennial update at different times. Ross County had its last sexennial appraisal in 2019 making tax year 2022 (payable this year 2023) our triennial update.  If you have questions or concerns about the change in valuation of your property, please contact the Real Estate Department of the Ross County Auditor’s Office at (740) 702-3080 or by email at
