The Director of Assessment is the governmental official responsible for establishing the value of property for ad valorem tax purposes; for discovering, listing and valuing all taxable and tax-exempt properties; and to ensure that the individual property owner’s value is proper so that the owner pays no more than their fair share of the property tax. In the performance of these duties, assurance is made that no property escapes the assessment process or is under assessed and that no property owner received unauthorized preferential treatment. Revaluations are completed every five years in conformity with the Connecticut General Statutes and Revaluation Performance Standards. Development and updating of information is conducted on an ongoing basis, including modernization of computerized records of real estate, personal property and motor vehicles. Duties are performed in compliance with State of Connecticut mandated General Statues.
