Assessment records are available for public viewing during regular business hours Monday - Thursday from 8 a.m. to 4:30 p.m. and Friday 8 a.m. to 12 p.m. in the municipal offices at 136 North Monroe Street in Waterloo.

Each year the City of Waterloo, by state statute, is required to formally schedule periods of time for review of the assessment records.

This time is known as "Open Book." The next open book day is 2024.

In order to make an appointment for Open Book please contact our Assessor, Allen Sunstrom, at 1.800.721.4157 ext 8810.
