Real Estate & Property Records

The Auditor's Office maintains records of current property ownership within Story County for taxation purposes (§331.511 - 512 of the Code of Iowa). These records are available to the public and consist of the following:

  • Aerial photos
  • Plat maps (tax maps of property)
  • Public terminal access to our real estate database
  • Transfer books (history of all recorded transfers of a property)


The real estate staff members work closely with the County Assessor, the City of Ames Assessor, the County Recorder, and County Planning and Development to process deeds, transfer properties, apply homestead, military, agricultural land and family farm credits, review surveys and subdivisions, and update our plat maps. Each year the Auditor's Office generates the valuation report for the county's taxing authorities and prepares and certifies tax levies which are collected by the County Treasurer.
