About This Market
Boston's general contracting market is red-hot but cutthroat. Historic housing stock drives constant renovation demand - triple-deckers, brownstones, colonials all need updates. Competition is fierce with 785 licensed establishments statewide fighting for work. High material costs, labor shortages, and strict historical preservation rules push prices up. Permitting delays are routine, especially in Back Bay and Beacon Hill where every nail needs approval. Winter slows exterior work but smart contractors pivot to interior projects. Boston clients expect quality and aren't afraid to pay for it, but they'll ride you hard on timelines and change orders. Historical district work requires specialized knowledge - Cambridge and Somerville have different rules than downtown Boston. Get your CSL license first, then register with the AG's office. Build relationships with inspectors early because you'll see them constantly. Keep 6 months operating capital minimum because payment cycles stretch long on big residential jobs. Sub relationships matter more here than anywhere - good electricians and plumbers book months out. Price aggressively but pad your timeline because nothing moves fast in this city.
