What affects the cost in Boston?

Pricing in Boston is primarily driven by limited contractor availability driven by labor constraints, which carries more weight here than in lower-cost markets. While Massachusetts's regional cost environment is a moderately above-average cost state (RPP 105.8), above-average labor costs driven by limited contractor capacity and above-average local demand are the factors pushing individual project bids higher.
