Housing Owner-Occupied % of Units, by Zip Code (ZCTA5) — Massachusetts

NOTE: Gray indicates insufficient data or a suppressed estimate.

Owner-occupancy rates are consistently highest—often exceeding 85–90%—across the suburban and exurban zip codes of central and western Massachusetts, as well as in outer-ring communities south and west of Boston. The Boston metro core, including zip codes in and around the city proper, Cambridge, and Somerville, displays the lowest owner-occupancy rates, frequently falling below 40–50%, with similarly low clusters visible in Springfield, Holyoke, New Bedford, and Fall River. Cape Cod and the Islands present a mixed pattern, with moderate owner-occupancy in many areas but notably lower rates in Provincetown and parts of Nantucket, likely reflecting high concentrations of seasonal rental housing.
