Tracking 27,173 properties across Brockton, Massachusetts — a community where the median home dates to 1958 and the oldest to 1729. Every parcel mapped with building characteristics, environmental exposure, hazard risk, and ownership history assembled from 140+ sources.
Brockton is the largest city in Plymouth County and one of the most densely populated communities on the South Shore. The city's industrial heritage in shoe manufacturing built the dense neighborhoods of multi-family housing — triple-deckers, two-families, and small apartment buildings — that characterize the older sections. The downtown retains its industrial-era commercial buildings, and the surrounding neighborhoods span from the dense urban core to more suburban areas on the city's periphery.
Brockton has one of the most diverse populations in Massachusetts, and its housing stock reflects a full range of property types and conditions. For property professionals, Brockton is an urban market where building condition varies enormously — a renovated property and one with deferred maintenance can sit on the same block — and where the dense multi-family stock requires attention to per-unit economics, code compliance, and systems assessment. Assessed values remain among the most affordable in the metro Boston commuter shed.
