Overview
The ALL NEW Massachusetts Interactive Property Map, developed in ArcGIS Experience Builder by MassGIS, enables developers, banks, realtors, businesses, and homeowners to view seamless property information across the Commonwealth. This new version is optimized for desktop, tablet and mobile devices.
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

End Notes
1. Parcel Mapping
For full details about the statewide parcel mapping project and to download these free data for use in GIS software, see:
- MassGIS Standard for Digital Parcels and Related Data Sets
- Standardized Assessors' Parcels data layer (AKA Property Tax Parcels)
2. Property Assessments
MassGIS displays the most recent annual updates of property information for each community delivered to MassGIS. This, however, depends on how frequently the municipalities or their consultants submit standardized assessor maps and assessor information. Many communities submit parcel data annually, but not all do, so 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 hosted 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.
