How it works
The Massachusetts licensing system in plain English
Massachusetts separates consumer-facing home improvement registration from building-supervision credentials. HIC registration is the common statewide check for residential improvement work, but many structural, alteration, and permit-heavy jobs also call for a Construction Supervisor License held by the person overseeing the work. For homeowners, that means a kitchen refresh and a wall-removal renovation may involve different credential expectations. The safest approach is to ask which credential covers the contract and which covers the permitted building work.
§ 03
What to verify
Before you sign anything
Start with the state's HIC registration lookup to confirm the business is registered for home improvement work. Then ask whether the job also requires a CSL and verify that supervisor credential if structural changes, major alterations, or permit-triggering work are involved. Check active status, exact legal name, and expiration dates. If the contractor only offers one credential for a major building project, ask who holds the other required authority.

Homeowner tips
Practical guidance for Massachusetts
- 01 For any project touching structure, ask two separate questions: Who is the HIC and who is the CSL?
- 02 Do not confuse a company's HIC registration with a supervisor's CSL; Massachusetts treats them differently for a reason.
- 03 On decks, additions, and wall-removal remodels, expect the CSL issue to come up early if the contractor is experienced.
- 04 Match the HIC-registered business name to the payment recipient even if the CSL is held by an individual supervisor.
- 05 If a contractor says the permit will be pulled by someone else, ask to verify that person's CSL before signing.

Frequently asked
Massachusetts-specific licensing questions
01 Does Massachusetts require home improvement contractors to be registered? ▸
Yes. Massachusetts requires home improvement contractors to register under M.G.L. Chapter 142A for residential improvement projects valued at $1,000 or more. Registration is administered through the Office of Consumer Affairs and Business Regulation (OCABR). For projects requiring permits — additions, structural changes, wall removals — the contractor or their supervisor must also hold a Construction Supervisor License (CSL) issued separately by the Division of Professional Licensure (DPL). Always verify both credentials for permit-heavy work.
02 What is the difference between an HIC registration and a CSL in Massachusetts? ▸
An HIC (Home Improvement Contractor) registration is a consumer protection credential required for businesses doing residential improvement work over $1,000 — it does not require a competency exam. A CSL (Construction Supervisor License) is a separate, exam-based license required for anyone supervising construction that involves structural work or requires a permit. A company can hold an HIC registration while an individual supervisor holds the CSL. For any project involving permits or structural changes, you need to verify both.
03 Is there a dollar threshold below which I don't need a registered contractor in Massachusetts? ▸
Yes. HIC registration under M.G.L. Chapter 142A is required for home improvement projects at $1,000 or more in combined labor and materials. Below that threshold, HIC registration may not be required, but specialty trade licenses — electrical, plumbing, gas fitting — still apply regardless of project size. Chapter 142A also requires written contracts for all covered projects.
04 Can I do my own home improvement work without a registered contractor in Massachusetts? ▸
Yes. Massachusetts allows homeowners to perform work on their own primary residence without HIC registration or a CSL. You must own and occupy the property. Permits may still be required, and pulling them as an owner-builder makes you responsible for code compliance. The exemption does not apply to work done for others or properties being renovated primarily for resale.
05 What registration or license does a general contractor need in Massachusetts? ▸
For most residential home improvement work, a contractor needs an active HIC registration through OCABR. For projects involving structural changes, additions, or permitted work, the person supervising construction must hold a valid CSL from DPL — with the appropriate license class (Unrestricted, 1- & 2-Family, or specialty). Specialty trade contractors hold separate state licenses for electrical, plumbing, HVAC, and gas fitting issued by DPL.
06 How do I verify a contractor's credentials in Massachusetts? ▸
Verify HIC registration at mass.gov/ocabr and verify CSL credentials at the DPL license lookup at mass.gov/dpl. Search by contractor name or registration/license number. Confirm both credentials are active and that the CSL class covers your project type. Match the HIC-registered business name exactly to the entity on your contract. For specialty trade work, verify each trade license separately through DPL.
07 What does an active vs. inactive registration mean in Massachusetts? ▸
An Active HIC registration means the contractor is in good standing with OCABR and legally authorized to perform home improvement work. An expired or inactive registration means they cannot legally do covered work until reinstated. The same applies to CSL status — an inactive or expired CSL means the supervisor cannot legally oversee permitted construction. Always verify both before signing any contract.
08 What insurance and bond does a registered contractor need in Massachusetts? ▸
HIC registration under Chapter 142A requires contractors to carry general liability insurance and workers' compensation if they have employees. There is no state-mandated surety bond for HIC registration, but Chapter 142A provides homeowners access to the Guaranty Fund — a state fund that can reimburse homeowners for contractor abandonment or serious deficiencies up to $10,000. Always request certificates of insurance and verify them independently.
09 What happens if a contractor works without registration in Massachusetts? ▸
Performing home improvement work over $1,000 without HIC registration violates M.G.L. Chapter 142A, subject to civil penalties and fines. The OCABR can issue cease-and-desist orders. Unregistered contractors cannot access the state Guaranty Fund, and contracts with unregistered contractors may be unenforceable. Homeowners retain recourse under Massachusetts consumer protection law, M.G.L. Chapter 93A.
10 My contractor's registration expired mid-project — what now? ▸
An expired HIC registration means the contractor is no longer authorized to perform home improvement work. Stop payments for work performed after the expiration date and require reinstatement before continuing. Verify Active status on the OCABR website before releasing further payments. An expired registration may also affect the contractor's eligibility for the Guaranty Fund — consult OCABR about your options.
11 Am I liable if an unregistered worker gets hurt on my property in Massachusetts? ▸
Potentially yes. If a contractor has no workers' compensation insurance and an employee is injured, Massachusetts law may expose you to liability for medical costs and disability benefits as the de facto employer. Chapter 142A's registration requirement includes workers' comp verification — hiring a registered contractor with current coverage eliminates this risk.
12 How do I file a complaint against a contractor in Massachusetts? ▸
File a complaint with OCABR at mass.gov/ocabr. Massachusetts also provides a binding arbitration program under Chapter 142A for disputes between homeowners and HIC-registered contractors — a faster alternative to court. For Guaranty Fund claims (contractor abandonment, incomplete work), file through OCABR. For unlicensed contractor fraud, contact the Massachusetts Attorney General's Consumer Protection Division.
