The County Assessor assesses all residential, commercial, industrial and agricultural properties. Real property is revalued every two years.

The County Assessor's office currently has a four-person appraisal staff that may work individually or as a team. These appraisers visit any property in the county or municipality, outside of Iowa City, including new construction and existing properties needing reassessment.
