Greater Boston MSA Construction

Construction in Boston remains active but is slowing from recent highs. The market delivered more than 9,300 units in 2025, a five-year high, but 2026 deliveries are expected to decline as higher financing costs, construction expenses, and labor uncertainty weigh on new starts. Roughly 13,300 units are currently underway, equal to about 4.4% of inventory. Development remains concentrated in urban and northern suburban submarkets, including Route 1 North, Everett/Malden/Medford/Melrose, and Somerville/Charlestown. New supply still leans toward higher-end product, though more recent activity has shifted toward mid-tier projects. Office-to-residential conversions could add future supply, but rent control uncertainty may limit development appetite.
