Formal reassessment notices being mailed to property owners

In early 2017, Delaware County was ordered by the Court to conduct and implement a Countywide Reassessment of all properties in the County to be effective January 1, 2021. In November of 2017, the County contracted with Tyler Technologies to perform valuation services in conjunction with the Countywide Reassessment. County staff and Tyler Technologies have worked diligently to ensure that the Reassessment Project would be completed in accordance with the Court’s timeline.

The new assessments have been finalized and the County mailed formal reassessment notices to all property owners on July 1, 2020.

Delaware County Council asked the Court to establish an extended deadline of September 1, 2020 for all appeals from the Countywide Reassessment notices due to the concern that residents could inadvertently miss an earlier deadline. The Court has granted the request. All appeals from the Countywide Reassessment notices must be received or postmarked by September 1, 2020.
