Assessor's GIS Parcel Maps

The Town of Duxbury, along with the Board of Assessors is pleased to provide this link to the Towns

CAI GIS Mapping System

In September of 2019 the Town partnered with CAI Technologies whose specialty is local government parcel data development. This new GIS application for the Town works on all devices and computers. Properties are searchable by parcel ID, owner or address. Information on any parcel can be found by using the “i” or Identify icon which your pointer is automatically set to when you open the application. Click on any parcel for an information box on that parcel. Within the pop up window you will find information specific to that parcel as well as the most current Fiscal Year Property Record Card.

Many different aerial photo views are available within the Base Map Icon in the upper right corner of the map.  The most current Town of Duxbury images from April of 2018 can be found in the Local tab of the Base Maps.

Various mapping layers are found on the left of the application.

Please hover over any of the icons for a short description of its function.

We hope you enjoy these maps and please contact the Assessor’s Office with any questions at
