Ohio law requires Union County property values to be updated in 2019 to reflect the state of the local real estate market. A tentative value has been determined for all Union County properties. Every effort has been made to establish a fair and equitable value on each property, but property owners who have questions or would like to discuss their new value with one or our representatives, please visit us during the month of September at one of our Informal Value Review Schedule locations throughout Union County. You may visit the location of your choice within the pre-determined hours for each location. If you own commercial property, please call the Union County Auditor's Office at 937-645-3003 to schedule an appointment.
