Your guide to property assessment review in the Town of Greece

In accordance with New York State law, the Town of Greece is required to maintain up-to-date assessment records. To meet the State's guidelines, the Town of Greece conducts valuation updates annually. 

How the Valuation Process Works

Annual reassessment is the systematic review of town assessments to maintain a uniform percentage of value. This requires the Assessor to analyze and evaluate the market, and change where appropriate. 

To assist in your search, a comparable property is one of the same style of construction as your own. In the "style" column of the listing you will note a number indicating the type of home. To ensure that you are choosing accurate comparables make certain that you choose homes with the same style number as your own.

The following information has been prepared to help you understand the Valuation Update process.

Why Assess Properties?

In addition to keeping values up to date, a valuation update allows the Assessor to keep pace with property changes and market conditions as well as inequities which may exist in the assessment roll. A properly conducted valuation update will result in each property taxpayer paying their fair share.

Why does the valuation of my property need to be reviewed?

The Town of Greece must perform valuation reviews in accordance with New York State law. The goal is to ensure that every property owner is responsible for their fair share.

Who determines assessments?

The Town Assessor is responsible for assessing all of the properties at a uniform % of current market value. The Assessor bases the assessed value on information obtained through Mass Appraisals conducted on all properties, as determined by market value. 

Does an assessment increase mean my taxes will also be increased?

The assessment process is performed to correct inequities that creep into the assessment roll. When this happens some property owners may be paying more than their fair share in taxes while others are paying less. A town-wide valuation update serves to equalize these inequities. As a result of assessment adjustments, some property owners may notice a change in the overall amount of taxes.

If I believe my assessment is incorrect, how may I challenge it?

A specific grievance process, guided by New York State law, is in place to allow you to challenge your assessment. Helpful information about the review process is available in the Assessor's Office at the Greece Town Hall and on-line at

Challenging Assessments

All property owners have the right to a review of their property assessment. The process by which assessments may be challenged involves the following three options:

  • Informal Hearing
  • Formal Grievance Process
  • Small Claims Court
