Factors that change your Boston estimate
Boston-specific considerations
Two local factors matter here. First, Boston is a high cost-of-living market that carries through directly to labor rates. Second, on permitting: the city's older housing stock and historic district overlays can add review steps for exterior-facing projects. The regional climate — cold winters with significant freeze-thaw cycling — rounds out the planning picture.
