Assessments & Valuation

At the March 13, 2012 meeting of the Town/Village Board of Trustees, a resolution was approved authorizing the Village Manager to enter into a contract for a 2014 revaluation, also commonly referred to as a reassessment, of all Scarsdale properties with Tyler Technologies/CLT Appraisal Services, Inc.

The 2014 Scarsdale Revaluation was completed via a computer-assisted mass appraisal system. The data collection phase of the project commenced on or about May 1, 2012. The new assessments were implemented on the June 2, 2014 tentative assessment roll, which was finalized on September 15, 2014 and will be the basis for all taxes levied in 2015.

Computer-Assisted Mass Appraisal


Mass appraisal is the process of valuing a group of properties, as of a given date, using common data, standardized methods and statistical testing (IAAO {1990, chapter 5} and Gloudemans [1999, chapter 5]).

To determine a parcel's value, assessing officers must rely upon valuation equations, tables and schedules, developed through mathematical analysis of market data. Values for individual parcels should not be based solely on the sale price of a property; rather upon valuation schedules and models that should be consistently applied to property data that is correct, complete and up-to-date. The development, construction and use of a computer-assisted mass appraisal system, when properly processed and administered, results in the production of a credible and defensible valuation system characterized by accuracy, uniformity, equity, reliability and low per-parcel production costs. Except for unusual, or unique properties, individual analyses and appraisals of properties are not practical for ad valorem tax purposes. Further, mass valuations are neither individualized, nor customized.
