How it works

Find any parcel in three steps.

  1. Open the map

    It starts on Massachusetts satellite imagery.

  2. Search or zoom in

    Type an address or coordinates, or zoom to street level. Property lines appear in yellow once you are close enough to tell parcels apart.

  3. Tap a parcel

    It outlines in orange and shows the owner name, site address, acreage, parcel ID and assessed value the state has on record.

FAQ

Massachusetts property lines, answered.

Yes. This map draws Massachusetts parcel boundaries from MassGIS's public statewide parcel layer (all 351 cities and towns) on satellite imagery. It is free, with no account, no trial, and no app to install. Search an address or zoom in, then tap any parcel to see its owner name, site address, acreage, parcel ID and assessed value.

From MassGIS, which publishes the layer as a public web service. The map asks that service for the parcels in view each time you move it, so you see the state's current copy rather than a stored one. Each of Massachusetts’ 351 cities and towns maps its own assessor parcels; MassGIS standardizes them into one statewide layer.

No. Parcel maps are drawn from deeds and tax records for assessment, and lines can be off by several feet or more, especially in rural areas. They are good for finding a property and getting a sense of its shape and size. For a fence, a building setback, or a boundary dispute, hire a licensed land surveyor, whose survey is the legal record.

Yes. MassGIS includes the owner of record in the public parcel data, so tapping a parcel shows the name on the tax roll. That is the owner as the local assessor has it, which can lag a recent sale by weeks or months.

They are good tools and they cover every county in the country, which is what their subscription pays for. If you only need Massachusetts, the state already publishes the parcel lines for free, and this map simply puts them on satellite imagery you can search.
