General Information

Assessor's Office

The purpose and function of the Assessor's Office is to provide an effective Property Assessment Administration System to establish and maintain equitable and uniform valuations for all taxable Real Estate and business Personal Property assets as mandated by the Wisconsin State Statutes. The Assessor's Office also maintains all annual assessment records relative to changes from the prior year and many associated legal documents. We provide reports as required by Statute and the Wisconsin Property Assessment Manual (WPAM) to the Department of Revenue and various other governmental departments and divisions.

One of the most important functions of the Assessor's Office is to provide the public with information on ad valorem valuation (assessments), mass appraisal assessment practices and procedures. The Assessor's Office also supplies various City and County Departments with an assortment of assessment data and details related to City services and the year-end tax bills.

The Assessor's Office gets its authority and instructions from the Wisconsin Statutes in Chapter 70, the Department of Revenue and the Wisconsin Property Assessment Manual (WPAM), and via decisions rendered by the Wisconsin Court System. Our work is also conducted in association with the guidelines and standards of the International Association of Assessing Officers (IAAO) and the Uniform Standards of Professional Appraisal Practices (USPAP) Standard 6.

In accordance with the Wisconsin Statutes and the WPAM, the City of Fond du Lac conducted a Market Update Revaluation for the 2014 Assessment Year. All real estate values were reviewed and adjusted to reflect an estimated 100% of market value as of January 1, 2014 based on actual sales data from within the city. Additional review and considerations were made for income producing commercial parcels for that revaluation.

Open Book dates should occur in mid to late April, appointments are highly recommended once dates are available. The Board of Review (BOR) cases are then held mid to late May to review all official objections filed with the City Clerk.

Please contact our main office telephone number at 920-322-3410 or email us at assessors@fdl.wi.gov with any questions related to the pending Assessment Roll.
