City Hall Closure

City Hall is currently closed for in-person interaction until further notice. The Assessor’s Office will do everything in their power to insure that all information will be available through our website or email during this pandemic.  We will be monitoring our email and voicemail to provide the best service possible.


The City Assessor’s office is responsible for the valuation of all real and personal property located within the City of Green Bay for tax purposes. It is our responsibility to ensure fair and equitable assessments throughout the City.

City-wide Revaluation

The City will undergo a city-wide revaluation over the next couple of years. This process will take place in stages and will affect all properties in the City. Here is a list of Frequently Asked Questions that should help answer many of the questions you may have.

Our goal is to conduct an accurate and transparent revaluation. We greatly appreciate your cooperation in the revaluation process and ask that you please direct any additional questions to the Assessor’s Office. 


The Assessor’s office does not set the tax rate nor raise taxes to cover municipal budgets. Our valuation process operates independently of the budget and tax process. The assessment procedure is governed by Chapter 70 of the Wisconsin State Statutes and the Wisconsin Property Assessment Manual. The laws are very specific as to how the work is carried out. 

The Assessor’s Office must be within 10% of market value, as defined by Statute, at least once in every 5 year period. Failure to comply with this requirement would result in a State ordered Reassessment paid for by the local government. It is our intention to use the most advanced assessment software to achieve uniformity on a regular basis.
