— Licensed · State-verified · Re-checked weekly
Find a licensed general contractor in Massachusetts
Every general contractor here holds an active state license, re-verified against the board weekly. Describe your project once. Get matched with licensed pros before you hand over a deposit. Free for homeowners.
Why verification matters
Remodels are where unlicensed contractors do the most damage - deposits taken, work abandoned, no bond to recover from. A state license means there is a real, accountable business behind the bid.

Statewide— How we verify
Where this list comes from
Every listing here holds an active license we pulled from the Massachusetts Office of Public Safety and Inspections (OPSI) — the government body that actually issues them — not from self-reported profiles.
We re-check license status against the board weekly and drop listings whose license lapses or is revoked. You can confirm any license number at the source yourself, and our free lookup guides show you exactly how.
Why ContractorRoster
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.
