The role of the Assessor's Office is the valuation of all real and personal property throughout the community.  The Department of Revenue requires that all property be valued at full and fair cash value, in compliance with Mass. General Law.

Throughout the year, the office works to evaluate all property sales with sales questionnaires and owner interviews, publicly available information and on-site inspections to confirm the property data at the time of the sale.  Theses inspections are essential for us to accurately interpret and analyze sales to develop our annual values.

Another key function is capturing new growth from permitting, construction and the addition of business personal property.  Property visits for permits are important so that we can accurately reflect the changes or additions to properties.  If we are not able to complete an inspection, we can only adjust based upon the limited information available to us.  At the time of these permit inspections, we hope to complete full property inspections for the confirmation of the total record in order to remain compliant with the Department of Revenue certification requirements.

The Select Board Held the Tax Classification Hearing on November 28th.  Westborough Will Maintain a Single Tax Rate for Fiscal 2024
