Tracking 28,845 properties across Cambridge, Massachusetts — a community where the median home dates to 1915 and the oldest to 1700. Every parcel mapped with building characteristics, environmental exposure, hazard risk, and ownership history assembled from 140+ sources.
Cambridge is one of the most complex property markets in New England. Home to Harvard University and MIT — institutions that together own or occupy a significant share of the city's land area — Cambridge combines world-class academic and research facilities with some of the densest and most expensive residential neighborhoods in the region. The city's housing stock spans everything from 17th-century colonial homes in the Brattle Street area to modern high-rise condominiums in Kendall Square.
The neighborhood variation within Cambridge is extreme. Harvard Square, Kendall Square, Central Square, Inman Square, and Porter Square each have distinct property characters, density patterns, and value profiles. Multi-family housing — triple-deckers, two-families, and small apartment buildings — dominates the residential stock, with single-family homes being a relative rarity. The biotech and technology boom has transformed Kendall Square and East Cambridge, driving commercial property values and creating development pressure throughout the city.
For property professionals, Cambridge demands parcel-level precision. A triple-decker in East Cambridge and a Victorian on Brattle Street are both "Cambridge residential properties," but they exist in completely different markets with different risk profiles, value drivers, and regulatory environments. The city's rent control history, its historic preservation districts, and its institutional land uses all create layers of complexity that generic data cannot capture.
