2026 Real Property Assessment Information

The City of Milwaukee Assessor’s Office typically performs a citywide revaluation every year, and has done so for 2026. A revaluation will result in changes to the assessed values for most properties. In a revaluation, the assessor looks at the prior years’ property sales and makes updates to assessments citywide, in addition to any necessary property changes and corrections. Revaluations are important to ensure that assessments are accurate and uniform. The assessed value determines what percentage of the City’s levy a property owner is responsible for, so accuracy and uniformity are necessary to ensure fairness.

In certain cases, a property owner will disagree with the assessed value established by the assessor. On the back of your 2026 assessment notice you will find instructions on how to appeal your assessment. We encourage you, however, to read through the FAQs below, as they may provide the answers to the questions you have. If you still have questions, we encourage you to call and talk with an appraiser about your assessment during the Open Book period, the period of time the assessment roll is open for examination. This year, Open Book will be held April 20-May 18, 2026, from 8:00 am-4:45 pm, Monday-Friday.
