Insurance requirements for licensed contractors in Massachusetts.

Does Massachusetts require contractors to carry insurance to be licensed?

Not in the way most people assume. Home Improvement Contractor (HIC) registration and Construction Supervisor License (CSL) are two separate credentials, and neither one is, strictly, a general liability insurance mandate. The statutory application requirements for HIC registration under M.G.L. c.142A §10 cover the applicant’s identity, ownership or officer information, and prior registration history, including any past judgments or arbitration awards and whether money is owed to the Guaranty Fund. Nowhere in that application does the state require proof of a general liability policy or set a minimum limit.

What the state does tell homeowners is to check a contractor’s HIC registration status and history, and then, separately, to ask the contractor directly for proof of liability insurance and workers’ compensation insurance if applicable. That phrasing matters: it’s advice for the consumer to verify on their own, not something OCABR checks as a condition of registering the contractor. CSL status gets the same treatment, confirmed separately if the renovation requires it.

The coverage that is actually mandatory, with statutory penalties attached, is workers’ compensation. That’s the piece of this puzzle a lot of contractors get wrong, assuming that if general liability isn’t checked at registration, nothing else will be either. Skipping workers’ comp is a different story entirely, covered below.

HIC registration: who needs it and what it actually checks

The HIC law covers contractors, subcontractors, partnerships, or corporations that solicit, bid on, or perform contracting work on an existing, owner-occupied residential property with one to four units. New construction, buildings with more than four units, investment or vacation properties, and homes outside Massachusetts fall outside the HIC law entirely. Some people are exempt regardless of the project: architects, electricians, plumbers and others working strictly within their own licensed professions, certain part-time or small jobs under $500, school construction-training programs, sellers of goods or materials only, and DIY homeowners on their own home.

Registration and renewal now run entirely through the MA Contractor Hub; paper applications and paper certified checks are no longer accepted. Registration must be renewed every two years. Let it lapse and reapplication costs a $150 registration fee plus a Guaranty Fund fee ranging from $100 to $500, scaled to how many people the contractor employs.

OCABR’s oversight isn’t purely administrative. The program processes consumer complaints, runs an arbitration process, and pays eligible homeowners out of the Guaranty Fund. It’s a consumer-protection framework built around competency and accountability, not an insurance-verification system.

CSL licensure and how it differs from HIC

A Construction Supervisor License is required for oversight of certain construction projects, and it is not interchangeable with HIC registration; a contractor doing residential remodeling work might need one, the other, or both depending on scope. To sit for the CSL exam, a candidate must verify three years of experience in building construction or design. The exam itself is administered by PSI, and after passing, the candidate mails the score report to the Board of Building Regulations and Standards along with any other required materials.

The code edition tested matters right now. Testing on the 9th Edition of the State Building Code ended December 31, 2024, with 10th Edition testing starting January 1, 2025. The 10th edition of the code (780 CMR) itself took effect October 11, 2024, and a concurrency period allowing use of either the 9th or 10th edition ran through June 30, 2025. Contractors who studied for the old exam or are relying on the older code cycle should confirm which edition currently governs their work.

Workers’ compensation: the coverage that is actually mandatory

Here’s the requirement with teeth. All employers operating in Massachusetts must carry workers’ compensation insurance for their employees, and for themselves if they’re an employee of their own company, regardless of hours worked or headcount. The only stated carve-out is for domestic employees, who must work at least 16 hours a week before coverage is triggered.

The DIA is explicit that workers’ compensation and liability insurance are not the same thing. Structuring your business doesn’t get you out of it either: members of an LLC, partners of an LLP, and sole proprietors of an unincorporated business aren’t required to cover themselves, but that exemption never extends to non-member employees, who must still be covered. Corporate officers holding at least a 25% ownership stake can request a self-exemption, but only for themselves. Out-of-state employers sending crews into Massachusetts owe the same coverage for every employee working in the Commonwealth, no matter where the home office sits.

General liability coverage against property damage and third-party injury claims isn’t statutorily mandated the way workers’ comp is, but a general liability policy is still the coverage most clients, GCs, and lenders will ask to see before letting a contractor on a job site.

What happens if you skip workers’ comp: stop-work orders and fines

DIA’s Office of Investigations issues Stop Work Orders (SWOs) to employers found without coverage. If the order isn’t appealed, the business must close immediately, and fines start at a minimum of $100 per day, including weekends and holidays, from the date the order was issued, accruing until coverage begins and the fine is paid. Appeal the order and the business can stay open, but the daily rate jumps to $250.

Separately, under M.G.L. c.152 §25C, an uninsured employer who doesn’t obtain coverage or self-insurance owes a civil penalty of $100 per day into the private employer trust fund for each day of noncompliance. Under §25C(5), failure to provide required insurance is punishable by a fine of not more than $1,500, imprisonment of not more than one year, or both, with corporate presidents or treasurers personally on the hook. Employers issued an SWO can also face criminal charges carrying up to one year in prison and a fine up to $1,500, plus debarment from public contracts for three years.

The affidavit requirements tied to municipal permits raise the stakes further. A city or town cannot issue or renew a license or permit to construct buildings to any applicant who hasn’t produced acceptable evidence of workers’ comp compliance, and under §25C(7), neither the Commonwealth nor its political subdivisions can enter a public works contract until that evidence is presented. Contractors who indicate on the affidavit that they use subcontractors must attach a list of those subs and, where the subs have employees, provide their workers’ comp policy numbers.

Subcontractor coverage and general contractor liability

A general contractor can be held liable for workers’ comp claims brought by a subcontractor or the subcontractor’s employees if that subcontractor doesn’t carry its own coverage. That exposure is why many GCs require subs to prove coverage upfront, or bring them under the GC’s own policy with the premium cost passed through, and money can be deducted from a sub for that coverage only if the contract provides for it or it’s otherwise explicitly agreed.

Who counts as an employee versus a genuine independent sub matters here too. Under M.G.L. c.149 §148B, workers are presumed to be employees. A hiring entity claiming independent-contractor status has to show the work is done free of its direction and control, is performed outside the entity’s usual course of business, and is done by someone with their own independent trade or business. Misclassify a crew and the workers’ comp exposure, and the fines that come with an SWO, land on the general contractor.

Contractors juggling tools, vehicles, and equipment across job sites should also look at how contractors’ equipment coverage fits alongside workers’ comp; the two protect different things but both get scrutinized during a renewal or an audit.

The Guaranty Fund vs. general liability insurance: what protects homeowners

It’s worth separating two things that get conflated constantly: the Residential Contractors’ Guaranty Fund and a contractor’s own general liability policy. The Guaranty Fund compensates eligible homeowners up to $25,000 for unpaid judgments against registered contractors. It exists to backstop consumers when a registered contractor won’t or can’t pay a judgment. It is not proof that the contractor carries liability insurance, and it isn’t a limit on what that contractor could actually owe in a lawsuit.

Homeowners are told to ask the contractor directly for proof of liability insurance and, if applicable, workers’ comp, precisely because the Guaranty Fund doesn’t cover that gap. For the contractor, carrying real general liability limits protects against exposure that a $25,000 fund was never designed to absorb, and it’s frequently the first document a client, lender, or GC will request before signing a contract.

What to bind before you take on a job

Before taking on residential work, confirm HIC registration is current through the MA Contractor Hub, and separately confirm CSL status if the project requires supervision oversight. Neither credential substitutes for the other. Get workers’ compensation in place for every employee, understanding that LLC members, LLP partners, and sole proprietors can exempt themselves but not their staff, and that out-of-state crews working in Massachusetts need the same coverage.

Carry general liability insurance even though no regulator checks for it at registration; clients, general contractors, and lenders will ask, and a certificate of insurance is usually how that proof gets exchanged. Put any residential contract over $1,000 in writing with the disclosures the law requires: registration number, the parties’ names and addresses, start and completion dates, and the owner’s three-day cancellation rights. If subs are on the job, get their coverage documentation before they set foot on site, not after an injury forces the question. Review the whole package, workers’ comp, general liability, and any equipment coverage, at each renewal rather than letting it run on autopilot between HIC renewal cycles.
