Assessors' Office

                     ***Important Update due to COVID 19***
      Update Regarding the Spring Permit Inspection Process

Every Spring, the Assessors conduct inspections on all properties with building permits
for assessment purposes. Due to COVID 19, this process has been temporarily changed. We will now conduct a site visit, take photographs, and use as many resources as available, including Town Hall records, to estimate your property as accurately as possible. Properties under construction will be assessed based upon percentage of completion. If the property is vacant and you are comfortable with scheduling an inspection, please feel free to contact us at (781) 383-4100 x 5124. 

The estimated assessments will be included in the Fiscal Year 2021 Preliminary Tax Bill, however, the actual assessments will not be finalized until December 2020.

Thank you for your patience as we work through this alternate method of collecting assessment data.
