About the Revaluation

In 2019, our Assessor’s Office will complete a revaluation. This is a city-wide complete and thorough review of all property assessments. We make value adjustments where necessary to guarantee that all property is assessed at market value. This ensures that taxes are distributed equitably.

Important Dates for Residential and Business Property Owners

  • Notices mailed to property owners: Mid August 2019
  • Open Book period (informal reviews): August 12 - September 12, 2019
  • Board of Review (formal reviews): September 2019
  • Tax Bills mailed with new assessments: December 2019

Open Book Period and Board of Review

Open Book Period ended September 12, 2019. However, our appraisers are still contacting those who reached out with questions. There are still avenues in which we can make changes to a property value if the changes are justified.

If you have unresolved issues with your property assessment, you must file an appeal before September 18 at 9 am. To appeal your assessment to the Board of Review, you must be able to demonstrate in a factual and meaningful way, that there is an error in the assessor’s valuation. Only actual sales of comparable properties are accepted as evidence.
