Am I required to let the municipal appraiser into my home?

       No. The Assessors (Board of Selectmen) are mandated to "make values anew" at least every 5 years. In order to accomplish that and make a fair assessment of your property a measure & listing of interior data is performed. If no interior listing is performed, an educated guess (using building permit information, Marshall & Swift Cost Manual data, and neighborhood data) is made and an assessment is established.  To challenge your assessed value because it is disproportionate to similar properties in your neighborhood or you found a data error you would file an abatement.

       Filing an abatement triggers an inspection. The Assessors need to verify the data is incorrect or verify the reason of disproportionate value.
