Seamless Property Mapping Across the State

The Massachusetts Interactive Property Map, developed by MassGIS, enables developers, banks, realtors, businesses, and homeowners to view seamless property information across the Commonwealth.

One of a handful of such state-sponsored tools in the country, the ongoing effort is the product of MassGIS working with community assessors, their mapping consultants, and other stakeholders. 1

    Using the Interactive Map

    For help using the interactive map, see the User's Guide, which includes details of the above features as well as instructions on how to download parcel data by city/town from within the application.

    Non-Map Property Information

    The assessment data are also available in accessible format in the Property Information Finder, which meets 508 Compliance Requirements and allows you to search for property assessment data by address only. It does not include a map or the other features provided by the Interactive Property Map.

    1. Parcel Mapping

    For full details about the statewide parcel mapping project and to download these free data for use in GIS software, see:

    2. Property Assessments

    MassGIS attempts to display annual updates of property information for each community. This, however, requires all communities to maintain and submit standardized assessor maps and assessor information. Until this effort is fully implemented, some of the assessor data may not be entirely current. The fiscal year of the information is displayed in a pop-up when you click a particular parcel.

    The most up-to-date assessing information is available directly from each municipality, typically through the assessing department. Many municipal web sites have an online property lookup feature, usually on the assessor's page.

    3. Data Sources

    The Massachusetts Interactive Property Map displays property boundaries from assessor parcel maps for all 351 cities and towns in the Commonwealth. Each parcel is linked to selected descriptive information from the municipalities' assessor databases. Data are provided to MassGIS from each city or town or their GIS mapping contractors.

    All data are served from MassGIS' ArcGIS Online organizational account. Boundaries (magenta lines) on the map are stored as a tile cache for fast display. Popup information is stored in a feature layer.

    4. Property Boundaries

    Assessor’s parcel mapping is a representation of property boundaries, not an authoritative source. 

    • The authoritative record of property boundaries is recorded at the registries of deeds.
    • A legally authoritative map of property boundaries can only be produced by a professional land surveyor.
