Property Revaluation Cycle in Hamilton County, Ohio Complete Guide 2026

The Property Revaluation Cycle in Hamilton County, Ohio for 2026 marks a Triennial Update based on recent market sales, not a full property inspection like the 2023 Sexennial Reappraisal. Values reflect conditions as of January 1, 2026, with auditor adjustments finalized mid-to-late 2026 and shown on January2027 tax bills. Property owners should monitor CAUV deadlines, review Homestead eligibility, and file Board of Revision appeals between January 1 and March 31 if needed.

Definition and Purpose

Property revaluation (or reappraisal) is the process through which Hamilton County updates the official value of all real estate properties. The goal is to ensure that all properties are assessed fairly based on current market values.

Ohio law requires all counties to review property values regularly, including a full reappraisal every six years and triennial updates in between.

How Property Values Are Determined

The Hamilton County Auditor considers multiple factors when determining property values:

• Location and neighborhood trends
• Property type (residential, commercial, industrial)
• Size, age, and condition of the property
• Recent sales of comparable properties

This ensures that your property value reflects the true market conditions, not outdated assessments.
