The state board's job ends at the license. Ours starts there.
GC licensing is jurisdiction-heavy: California separates A, B, and B-2; most states roll residential and commercial into one. Cross-checking who's actually active in a given city takes hours. ContractorRoster pulls every active GC license in the area, normalizes the classifications, and adds phone, email, and website for over 95% of records.
Massachusetts: Massachusetts licenses general contractors through the OPSI Construction Supervisor License (CSL) — required for anyone supervising construction on buildings containing one to four dwelling units or over 35,000 cubic feet of enclosed space. Electricians, plumbers, and HVAC trades sit on separate state portals and are not included in this dataset; home-improvement trades like roofing and painting fall under the HIC registration at contractorhub.mass.gov.
