Massachusetts contractor license: CSL and HIC

Search for a general contractor license in Massachusetts and you will not find one. The state splits the job in two. A Construction Supervisor License (CSL) belongs to the person who supervises structural work. A Home Improvement Contractor (HIC) registration belongs to the business that contracts with a homeowner. OCABR says it plainly: the two are different and not interchangeable.

A deck needs both; a kitchen renovation may. They need not sit in one pair of hands: a registered contractor can sign the homeowner and subcontract the larger work to someone who holds both the license and a registration. Whoever signs with the homeowner must hold the HIC. The requirements by state guide shows how other states handle the same split.

The CSL is issued by the Board of Building Regulations and Standards and run day to day by the Office of Public Safety and Inspections. It licenses a person to directly supervise work regulated by the state building code, 780 CMR. The board sets its reach by the size of the building, not by the value of the contract.

You must be 18 and show 3 years of experience in building construction or design in the field you want licensed. The handbook defines that as 36 months of full-time (40 hours a week) work inside the last 10 years. It need not be continuous. A vocational programme or a degree can stand in for part of it, up to 2 years. Union membership on its own does not count. Proof is W-2s, Schedule C or 1099s, or a letter of attestation from an employer, engineer, architect or licensed contractor. Our experience hours tracker keeps that tally as you go.

The exam is run by PSI. It is computer-based, multiple choice and open book: you bring your own copies of the code and the listed references, tabbed but not written in on the day. Every exam needs 70%, and failed attempts can be retaken without limit. Testing is on the tenth edition of the state building code.

On top of the exam fee, PSI charges a $23 application fee; neither is refundable. Once you pass, you have 1 year to send the license application and the licensure fee to the Division of Occupational Licensure, which processes it in about 30 days. Several specialty categories can go on one application for a single fee. The pages we read do not print the licensure fee itself; your score report carries the instructions and the amount.

The HIC is a registration for the business, held with the Office of Consumer Affairs and Business Regulation under M.G.L. c. 142A. Contractors, subcontractors, partnerships and corporations that solicit, bid on or perform work on an existing, owner-occupied home of one to four units must register. The registration page asks for no exam, only an application and the fees. You apply and pay online through the MA Contractor Hub; paper applications are sent back.

A new registration costs $150 plus a one-time payment into the Guaranty Fund, scaled to headcount:

The fund pays homeowners up to $25,000 of actual loss when a registered contractor does not pay an arbitration award or court judgment, and the contractor then owes the fund that money back with interest. Two eligibility tests fall on you: you were registered when the contract was signed, and you, not the homeowner, pulled the permit. Every building permit states that people who hire unregistered contractors have no access to the fund.

OCABR publishes a job-by-job chart. It calls it general guidance, and the local building official has the last word, but it settles most questions. A selection:

The chart’s own notes matter: siding and windows need at least the window-and-siding CSL, new roofs at least the roof-covering CSL, and a shed needs a permit and CSL once it passes 200 square feet on a 1- or 2-family lot. Electrical, plumbing and gas work sits with the licensed trades, not with either credential. If your work is mostly painting and repairs, the handyman versus contractor comparison maps where that line usually falls. For roofers, the roofing license guide compares Massachusetts with states that license roofing on its own.

The CSL renews for $100, and you must finish continuing education before you ask for the renewal. The board sends a notice 60 days before expiry and asks you to allow 5 weeks for processing.

Every license needs at least one hour in each of five topics: Code review, Workplace safety, Business practices / workers' comp, Energy, Lead safe practices. No more than 6 hours may be online; the rest is classroom. Finish the courses at least 60 days before expiry, and do not reuse a certificate from a past renewal.

The HIC renews every 2 years for $100. OCABR advises starting 30 to 60 days ahead. Let it lapse and you reapply at $150 plus the Guaranty Fund payment again, and your ability to pull permits may suffer meanwhile. Two dates on two cycles is exactly what the renewal tracker is for; the renewal guide covers the habits that stop a lapse.

There are two registers, so a full check is two searches. A CSL is searched on the OPSI license verification site by name, license number, city or ZIP; its records run from 2001. An HIC is searched on the MA Contractor Hub contractor search. Since every permit, contract and advert must carry the HIC number, ask for it first.

Our license lookup directory lists the search page for every board we have checked, and how to check a license explains what a clean record should show.
