About the official source
This is a statewide map, not a county site. MassGIS Interactive Property Map covers parcels across Massachusetts, and Berkshire County is one part of it. Because a state agency compiles this layer from local data, check with the Berkshire County assessor or recorder before relying on a recent change. Our October 2026 check found the map open to the public, with no account or payment needed.

A note on accuracy
Online parcel lines are drawn for tax and planning use. They can be off by several feet, so use a recorded plat or a licensed surveyor for fences, setbacks or a sale.
