Town of Groton Public Disclosure of Tax Valuation

The Groton Assessor’s office has been conducting the FY 2022 Quinquennial Revaluation as required by Mass. State Law. This update of values ensures that all property is assessed at full and fair market value as of January 1, 2021. The Assessor has received preliminary certification by the Mass. Dept. of Revenue. Public Disclosure period will be available to the public from Friday November 5th, 2021 to Friday November 12th, 2021.

The revaluation requires the verification, analysis and use of at arms-length sales from calendar year 2020. Sales from the year 2019 were used to value property when the numbers of 2020 sales were insufficient for analysis. Market trends may indicate that different property types may change in value more or less than other property types. On average, class 101, single-family homes increased in value by 6%, class102, condominiums increased by approximately 7%. Apartments class 111’s increased by 6%, class 112’s increased on average 6%. The commercial class increased by 2% and the industrial class by 2%. Individual parcel valuations may vary from the average class increase due to typical differences, data updates and corrections, new construction and the effect of market trends for specific characteristics.

The preliminary assessed values for FY 22 will be available for public review beginning Friday November 5th, 2021 through Friday November 12th, 2021 at the Assessor’s Office, the Groton Senior Center, and the Groton Public Library and on the Assessors web page of the Town of Groton website.

Contact the assessors’ office during the public disclosure period to ask questions, review, discuss and request changes in proposed values.

The Assessor’s Office is open from, 8:00 am to 7:00 pm Monday, 8:00 am to 4:00 Tuesday thru Thursday and 8:00 am to 1:00 on Friday.
