The Franklin County Auditor’s Office mobile application is the first ever auditor’s office app in Ohio history. This GPS-enabled app allows you to view property information (such as property value, building data and tax status) for properties near you or for any of the 440,000-plus parcels in Franklin County. In addition to the real estate search functions, this first-of-a-kind application offers information on the Homestead Exemption and Dog Licensing.
