This office lists and values all real property in Hamilton County, maintains the parcel mapping (GIS), and assigns addresses for new structures. Our goal is to give you what you need to understand your assessment and the exemptions available to you.

Through the online GIS Portal you can view and print the property record card for any parcel. The card shows how the property is assessed and what is being assessed. We work to keep the maps and cards accurate, but they are not survey quality and parcel boundaries may contain errors — if you find one, please contact us so we can correct it.
