City Assessor


The Assessor is the local official who estimates the value of real property within the City boundaries. The Assessor's responsibility is to prepare and maintain a fair and equitable assessment roll.  This roll contains the assessed value, ownership and exemption information for all the parcels located in the City of Plattsburgh. The assessment is one component used in the computation of tax bills. Some of the duties of the assessor are as follows:

  • Determine property use and ownership
  • Collect and maintain physical inventories for each parcel
  • Maintain property record cards
  • Collect new construction and demolition data
  • Maintain sales reporting system and corrections to the system
  • Review/analyze the market
  • Collaborate with Clinton County Real Property Services and NYS Department of Taxation and Finance: Office of Real Property Tax Services
  • Property Valuation
  • Explain and defend assessments; be present at Board of Assessment Review hearings
  • Administer Real Property exemption applications
  • Adhere to NYS Real Property Tax Law
  • Public relations

Market value is the price at which a parcel of real property would change hands between a willing seller and a willing buyer, neither being under any compulsion to buy or to sell and both having reasonable knowledge of relevant facts and a reasonable time for exposure in a free and open market.  The assessor uses these arm’s length transactions in deriving the assessments.  Cost, Income Capitalization and Direct Market approaches are valuation techniques used in determining the assessment.  The assessed value published in the Final Assessment Roll relies on sales that closed prior to July 1st of the previous year; which is the “effective date” of the assessment.  The sales data from this time period does not reflect “current” or present day’s market forces and sales information.  For example, on May 1, 2009 you are informed of your tentative assessment.  The sales data selected to create this 2009 tentative assessment roll is limited to sales data that transferred prior to July 1st, 2008; therefore the effective date of the assessment is July 1st, 2008.  The final assessment roll represents the market of the past.

All real property within the City of Plattsburgh is assessed at a uniform percentage of value.
