2020 Reappraisal Project


In 2019, the Town Board voted to conduct a reappraisal update of all real property located in the Town of Ossining for 2020. This project will provide the highest level of assessment accuracy.

Tyler Technologies, the firm that was awarded this project, is currently the oldest and largest provider of this service. Tyler Technologies has performed reassessment projects in New York State and nationally, since 1938, and also performed one for Ossining.

The most critical aspect of this project is the collection of accurate data. In order to correct discrepancies/errors or verify information about your property in the next few weeks, a data collector from Tyler will be visiting your property to perform a physical inspection. Your cooperation is appreciated and essential to establishing an accurate assessment.
