Licensed General Contractor in Massachusetts: How to Verify Before You Hire

Massachusetts requires contractors to hold both a Home Improvement Contractor (HIC) registration and a Construction Supervisor License (CSL), both administered by the Office of Consumer Affairs and Business Regulation (OCABR) at mass.gov. The dual-credential system makes Massachusetts one of the more rigorous states for residential contractor oversight, and both credentials must be verified before hiring.

What Is the Difference Between an HIC Registration and a CSL in Massachusetts?

The HIC registration covers the business entity performing home improvement work. Any contractor, contractor business, or salesperson soliciting residential home improvement work in Massachusetts must hold an HIC registration. The CSL, by contrast, is an individual license for the person who actually supervises the construction work. A project requires a licensed Construction Supervisor as the individual responsible for code compliance and quality control.

These two credentials serve different purposes. The HIC registration creates accountability for the business — it requires a $5,000 bond, proof of insurance, and creates a complaint channel. The CSL ensures that the individual overseeing the work has passed an exam demonstrating knowledge of Massachusetts building code. You need both: an HIC-registered company with a CSL-licensed supervisor.

Massachusetts issues several CSL endorsements. An Unrestricted CSL allows supervision of any residential construction. A 1- and 2-Family Restricted license limits the licensee to one- and two-family dwellings. A number of specialty restricted licenses cover specific scopes like roofing or framing. Confirm your contractor holds a CSL that covers the scope and scale of your project.

What Does Massachusetts's $5,000 Bond Requirement Cover?

Massachusetts requires HIC-registered contractors to carry a $5,000 surety bond. This is among the lower bond requirements in the Northeast — New York requires $25,000 and Pennsylvania requires $50,000. The $5,000 bond provides a modest baseline protection. For major renovation projects, it is advisable to require the contractor to carry a project-specific performance bond in addition to the statutory minimum.

The HIC bond can be claimed through OCABR's arbitration process if a contractor breaches the contract. Massachusetts also has a Home Improvement Contractor Guarantee Fund that provides additional recovery up to $10,000 per claim for homeowners who are unable to recover from a contractor's bond or insurance. This fund is specifically funded by HIC registration fees, making it a uniquely Massachusetts consumer protection.

How Does Massachusetts's Contractor Licensing System Work in Practice?

When you hire a Massachusetts contractor, ask for both the HIC registration number and the CSL number for the individual supervisor. Look up both at the OCABR website (mass.gov/ocabr). The HIC registry shows business registration status and bond information. The CSL database shows the individual license, endorsement type, expiration date, and any disciplinary history.

Massachusetts takes CSL violations seriously. The State Board of Building Regulations and Standards can suspend or revoke a CSL for code violations, abandonment, or fraud. A suspended CSL means the individual may not supervise construction work in Massachusetts — which means a project they supervise while suspended is in violation of state law.

How Do You Verify a Massachusetts Contractor's Credentials?

For HIC registration, search at mass.gov/hic. For CSL verification, search at mass.gov/csl. Both databases are free and searchable by name or number. Confirm HIC status shows “active,” the CSL shows “active” with the correct endorsement, and both are current before any project begins.

CheckLicensed.comsearches Massachusetts OCABR records for $0.99 per lookup, returning HIC registration and CSL status for any contractor. In a state where two separate credentials are required — one for the business and one for the individual supervisor — having a streamlined way to verify both is a genuine time-saver for Massachusetts homeowners.
