How to Verify a Contractor License in Massachusetts

TL;DR — Verifying a Contractor Registration in Massachusetts in 60 Seconds

Massachusetts requires Home Improvement Contractors to register with the Office of Consumer Affairs and Business Regulation (OCABR). This is a registration rather than a traditional license — Massachusetts does not require a general contractor exam. Electricians and plumbers are licensed separately by their respective state boards.

To verify a Massachusetts contractor, search on LicensedCheck.com or the OCABR contractor search. Confirm the registration is current and that the contractor carries the required insurance.

Best Contractor License Verification Tools for Massachusetts

LicensedCheck.com will soon include Massachusetts HIC registration data. Best for: homeowners in Boston, Worcester, Springfield, Cambridge, and across Massachusetts.

The OCABR contractor lookup at mass.gov is the official source for HIC registration verification. The Board of State Examiners of Electricians and the Board of State Examiners of Plumbers and Gas Fitters handle trade-specific licenses.

Which Massachusetts Trades Require State Licenses

Massachusetts requires HIC registration for anyone performing home improvement work. Electricians must be licensed by the Board of State Examiners of Electricians at journeyman or master level. Plumbers and gas fitters must be licensed by the Board of State Examiners of Plumbers and Gas Fitters.

Construction Supervisor Licenses (CSL) are required for anyone supervising residential construction. This is issued by the Board of Building Regulations and Standards. Massachusetts also licenses sheet metal workers, sprinkler fitters, and pipefitters.

The state maintains a Home Improvement Contractor Guaranty Fund that provides financial protection for homeowners who hire registered HIC contractors.

Protecting Yourself When Hiring in Massachusetts

Verify the HIC registration and any required trade licenses before hiring. For electrical or plumbing work, confirm the specific trade license — an HIC registration alone does not authorize electrical or plumbing work.

Massachusetts requires HIC-registered contractors to carry liability insurance and contribute to the Guaranty Fund. Only work by registered contractors is covered by the fund.

Get a written contract — Massachusetts law requires written contracts for home improvement work over $1,000. The contract must include specific details and the contractor's HIC registration number.

Watch for these red flags: a contractor without HIC registration, electricians or plumbers who cannot show a state trade license, anyone who refuses a written contract for work over $1,000, and contractors who demand more than one-third as a deposit. Verify first at LicensedCheck, then hire.

Red Flags and Consumer Protections in Massachusetts

Massachusetts requires contractor registration through the Office of Consumer Affairs and Business Regulation for all home improvement contractors. This is a registration system rather than a licensing exam, but it still requires contractors to carry minimum insurance and provides important consumer protections. Specific trades — electricians, plumbers, and gas fitters — require separate state licenses through their respective boards.

The Massachusetts Home Improvement Contractor Act provides strong consumer protections. Registered contractors must provide a written contract for all work over $1,000 that includes specific disclosures, a three-day right to cancel, and detailed payment terms. Contractors cannot demand more than one-third of the total price before work begins. Violations of the Act can be enforced under the Massachusetts Consumer Protection Act (Chapter 93A), which allows treble damages and attorney's fees.

Massachusetts also maintains the Guaranty Fund, which can reimburse homeowners for financial losses caused by registered contractors — up to $10,000 per claim. This fund is only available for work performed by registered contractors, which underscores the importance of verifying registration before hiring.

Verify contractor registration and trade licenses on LicensedCheck. Be especially careful during the post-storm period — Massachusetts sees a surge in unlicensed contractor activity after nor'easters and winter storms. The Attorney General's office and the Office of Consumer Affairs both accept contractor complaints. Report any contractor who is not registered or who violates the Home Improvement Contractor Act's requirements for written contracts and deposit limits.
