The mission of the Assessor's Office is to discover, list, and value all taxable property within the City of Pewaukee.  By providing accurate and uniform values, we ensure that the property tax burden is distributed in a fair and equitable manner.

 To accomplish its mission, the Assessor's Office uses methods in accordance with the Wisconsin Property Assessment Manual, which is available on this page, Wisconsin State Statutes, and professionally accepted appraisal practices. Other information that is available for assessors to consider includes the Uniform Standards of Professional Appraisal Practice (USPAP) and standards from the International Association of Assessing Officers (IAAO).

Wisconsin State Statute 70.32 states, "Real Property shall be valued by the Assessor in the manner specified in the Wisconsin property assessment manual provided under Section 73.03(2a) from actual view or from the best information that the Assessor can practicably obtain, at the full value which could ordinarily be obtained therefore at private sale".
