• Deepsel is our product: free estimate, invoice and scheduling software for home-service contractors (scheduling, quotes, invoicing, card payments). The section before the FAQ says where it fits and what it won't do for you.
• Not legal advice. I read every statute, regulation and agency page linked below on November 3, 2026. Your building department has the last word on permits, and a Massachusetts attorney on the rest.

Your Home Improvement Contractor (HIC) registration lets you sell and do home improvement work, at any price, on an existing home with one to four units that the owner lives in.¹² On its own it doesn't cover a job that needs a building permit. Those jobs (a new roof, windows, siding, most decks, taking out a wall) need a licensed construction supervisor in charge,³ and electrical, plumbing, gas and duct work go to their own licensed trades however small the job. A handyman without the registration has to keep each project under $500, or work part-time and stay under $5,000 a year.⁴

People call it the "HIC license." It's a registration: no exam, a fee, a Guaranty Fund payment and a renewal every two years. The state's own page states the biggest confusion in one line: "An HIC Registration is different from a Construction Supervisor License (CSL) and they are not interchangeable."⁵ The second confusion is the dollar line. Several handyman guides, and the AI summary Google showed me for "massachusetts handyman license," say registration starts above $1,000. That's the line for a written contract.⁶ The registration line is $500.

This is the page I'd want the week the registration card shows up: what the card covers, where it stops, what happens if you cross the line, and a table of common jobs with the rule behind each answer. Every rule links to the statute, regulation or agency page I read. The paperwork side (what your contract must say, and how much deposit you can take) is in the Massachusetts home improvement contract template.

What your HIC registration covers

Chapter 142A calls the work "residential contracting": "the reconstruction, alteration, renovation, repair, modernization, conversion, improvement, removal, or demolition, or the construction of an addition to any pre-existing owner occupied building containing at least one but not more than four dwelling units," plus structures next to it.¹ OCABR's regulation gives garages, sheds, cabanas, pool houses and gazebos as examples of those structures.⁷ No contractor or subcontractor may "undertake, offer to undertake, or agree to perform" that work without the registration.²

Three questions decide whether a job is HIC work:

• Is the building already there? A new house isn't "pre-existing."
• Does the owner live there as their primary residence? A condo owner in a building of four units or fewer counts, and so does a tenant the owner has authorized. An LLC, corporation, partnership or business trust doesn't count as an owner.⁷
• Does the building have one to four units?

Inside that box the registration has no dollar ceiling and no list of allowed job types; I found no cap anywhere in Chapter 142A. What it gives your customers is protection: the state's arbitration program⁸ and a Guaranty Fund that pays homeowners when a registered contractor doesn't pay a judgment or award against them.⁹ What it costs you is $150, a Guaranty Fund payment of $100 to $500 depending on how many people you employ, and a renewal every two years.⁵

Outside the box (a new build, a rental the owner doesn't live in, a building with five or more units, a shop) you don't need the registration. You still need a permit and a licensed construction supervisor (or, on big buildings, an architect or engineer) for permit work there, because the state building code "applies to all buildings and structures in the Commonwealth."¹⁰

Two groups people forget. Subcontractors doing HIC work need their own registration, since the law says "contractor or subcontractor."² And a CSL holder still needs the HIC: the exemption for licensed tradespeople working inside their license ends with the words "construction supervisors excepted."⁴ Licensed electricians and plumbers doing only electrical or plumbing work don't need it.

Massachusetts handyman license: the $500 and $5,000 lines

Massachusetts has no handyman license. For a handyman the question is whether you're exempt from the HIC registration, and Section 14 of Chapter 142A answers it. You're exempt if any of these is true:⁴

• The project is under $500. The exemption covers a contractor "who works on one undertaking or project by one or more contracts where the aggregate contract price is less than five hundred dollars," as long as the contract isn't kept under $500 "for the purpose of evading this chapter."
• You work part-time and earned under $5,000. The law's words: "on other than a full-time basis, and who has earned in gross revenues, as a contractor or subcontractor, less than five thousand dollars in the previous twelve-month period."
• All your work is in the listed trades: landscaping, interior painting or wallpaper, finished flooring (carpet, vinyl, tile), fences and freestanding masonry walls, above-ground pools, shutters and awnings, ground-level patios, or asphalt and driveways. The regulation adds that ground-level patios exclude "decks which are supported above ground."⁷
• You work for wages for a contractor, sell materials without installing them, or work on your own home.

How the $500 is counted

• Per project, all contracts together. Two $300 invoices for the same bathroom make a $600 project. Splitting a job to stay under $500 is what the "evading" clause is there to catch.
• The full price to the owner, materials included. The regulation says "aggregate contract price to the owner."⁷ The state's law libraries describe the $1,000 contract line as "work costing more than $1,000 including materials and labor,"¹¹ and I'd count the $500 line the same way.
• Under means under. A $500 job isn't exempt.
• The part-time test looks back 12 months from the date of each contract, and you have to be part-time as well. A full-timer in his first month with $3,000 of revenue doesn't get the part-time exemption.

The regulation lists the under-$500 project and the part-time earner as two separate exemptions, (g) and (h).⁷ A couple of national guides say OCABR reads the $500 line as only covering contractors who aren't "regularly engaged" in the work. I couldn't find that wording in the statute, the regulation or OCABR's pages. If you do small jobs every week, though, the safe course is to register. That's $250 to $650 up front; one violation can cost up to $2,000.¹²

Three numbers people mix up

• $500: below this, one project needs no registration.⁴
• $1,000: above this, the contract must be in writing and include the items Chapter 142A lists.⁶
• $25: above this, a household job agreed anywhere other than your business address comes with a three-day right to cancel.¹³

So how much can a handyman charge without a license in Massachusetts? Under $500 for the whole project, or any amount while you're part-time and under $5,000 for the past 12 months. Neither exemption reaches the electrical, plumbing, permit and lead rules below; those apply to everyone. And a contractor who is exempt and doesn't register sits outside Chapter 142A altogether,⁷ so the customer gets no Guaranty Fund. If you're setting prices for small jobs, my handyman price list covers job prices and minimums.

HIC vs CSL: the Massachusetts construction supervisor license

The CSL is the license that tests whether you can build. It comes from the Board of Building Regulations and Standards under the building code, and the rule is one sentence: "Individuals supervising persons engaged in construction, reconstruction, alteration, repair, removal or demolition involving any activity regulated by any provision of 780 CMR, shall be licensed."³ In practice: if the job needs a building permit, a CSL holder in the right category has to run it. The permit application carries that person's "name, signature and license number," and if they stop supervising, "the work shall immediately cease" until another license holder takes over.³

The state's summary for the homes your customers live in: "For most existing 1- to 4-family owner-occupied homes A licensed construction supervisor or a registered design professional (RDP) must oversee construction ... A contractor must also register with the home improvement program."¹⁰ Big remodels need both cards. A Massachusetts carpenter on Reddit described the gap from inside a job: "the crew(s) the client hired doesn't have a construction supervisor's license (required in MA to pull permits if not the homeowner). I, however, do have my CSL."¹⁴

The CSL categories

The categories come from the code's own license table.³ Getting a CSL takes three years of experience within the last ten and a passed exam, run by PSI.³¹⁵ The first license lasts three years and renewals two, with 12 hours of continuing education per cycle for the full CSL, 10 for one- and two-family and 6 for a specialty.³

Holding the card means showing up. The license holder or a licensed designee has to be on site "at some point to approve" the foundation work, the framing, the insulation and air barriers, the smoke and carbon monoxide detectors, chimneys, and retaining walls over four feet.³

If you don't hold a CSL yet

Three legal ways to take a permit job:

• Bring in a CSL holder (an employee, a partner or a sub) who signs the permit and supervises. They carry the risk: the license holder "shall be fully and completely responsible for all work for which he or she is supervising," even as "only a subcontractor or contractor to the permit holder."³
• Stick to work that needs no building permit (next section).
• Let the homeowner pull the permit. A homeowner doing their own permit work is exempt from the CSL rule, but if they hire people, "such homeowner shall act as supervisor."³ Your contract has to warn them that "homeowners who secure their own permits will be excluded from the guaranty fund."⁶ I'd use this only when the owner really runs the job. And a CSL holder who contracts for the work is responsible for code compliance "whether or not the licensed contractor secured the permit."³

The fourth way isn't legal: a CSL holder lending their number to a crew they don't supervise. A builder asked on Reddit, "Ever pimp out your license to someone else to pull a permit?" The replies talked him out of it: "Never attach your name to anything in a legal way that you don't have control over... Just a recipe for disaster."¹⁶ In the Massachusetts thread above, a commenter gave the permit holder's side: "Shady. You, as the permit holder will be left holding the bag if something goes wrong. That includes callbacks and warranties."¹⁴ The code lists "failure to properly supervise a project or be present at a work site" among the grounds for suspending or revoking a CSL.³

Which jobs need a building permit (and so a CSL)

The building code makes it "unlawful to construct, reconstruct, alter, repair, remove or demolish a building or structure" without a permit, then lists what's exempt.¹⁷ For one- and two-family homes, the current residential code exempts:¹⁷

• One-story detached sheds and playhouses up to 200 square feet
• Fences up to seven feet
• Retaining walls up to four feet that don't hold back a surcharge
• Sidewalks and driveways
• "Painting, papering, tiling, carpeting, cabinets, counter tops and similar finish work. (Permits may be required for Electrical, Plumbing, or Gas work)"
• Decks up to 200 square feet, no more than 30 inches above grade at any point, not attached to the house, and not serving a required exit door
• Prefabricated pools under 24 inches deep, swings and playground equipment, small window awnings and plastic-film greenhouses

Ordinary repairs need no permit either. Here's where the code draws the line: "A permit is required for work including but not limited to: the substantial cutting away of any wall, partition or portion thereof, the removal or cutting of any structural beam or load-bearing support, or the removal or change of any required means of egress."¹⁷ Note "any wall, partition." Taking out a non-bearing wall is still a permit job.

The state's consumer affairs office also publishes a chart of which jobs need an HIC, a CSL or a permit, "for general guidance only."¹⁸ It puts roof replacement, siding, windows and insulation under a specialty CSL with a permit; decks, structural carpentry, sheetrock, plaster, exterior stairs and new door openings under a CSL with a permit; and exterior painting under the HIC alone. Minor roof repairs need a CSL too, with a permit "unless considered an ordinary repair by the building official." Gutters, trim and locks are HIC work, with a CSL only in some cases: for gutters, "Building permit and CSL required if piercing the building envelope." An older chart from 2009, still linked from the state's CSL page, put minor roof repairs and gutters under the HIC alone, so don't go by that one. Your town's building official has the final say, and the state tells you to check with them.¹⁰

The building department will also want your HIC number on the permit application and proof of workers' compensation insurance before it issues the permit.¹⁷

Electrical, plumbing, gas and duct work: sub it out

Your HIC registration covers none of these, at any size. Each trade has its own board and its own license, and the CSL rule steps aside for "the practice of any trade licensed by agencies of the Commonwealth."³

Electrical: even a light fixture

Massachusetts licenses the business of "installing wires, conduits, apparatus, devices, fixtures, or other appliances for carrying or using electricity for light, heat, power, fire warning or security system purposes."¹⁹ The exceptions cover utilities, elevator work, telephone, cable and computer firms, and public lighting. There's none for a handyman or a like-for-like swap. Replacing a light fixture, a switch, an outlet or a hardwired smoke detector is an electrician's job. Anyone installing wiring or fixtures for hire also has to notify the local inspector of wires within five days of starting.²⁰ Low voltage isn't a free pass either. The electricians' board says "There is no generic exception for 'low voltage' wiring" and tells installers to check with the inspector of wires first.²¹

Plumbing: even a faucet

Plumbing in Massachusetts is "the installation, removal, maintenance, extension, and alteration of a plumbing system; of all piping, fixtures, fixed appliances, and appurtenances."²² The plumbers' board puts it bluntly: "Massachusetts law prohibits anyone but a licensed professional from installing, removing or repairing plumbing."²³ The Appeals Court backed the board in 2010, in a case about a Nantucket homeowner who plumbed his own house: the regulations "prohibiting unlicensed persons from performing plumbing work regardless of circumstance" stood.²⁴

Permits are a separate question. Fixing a leak in a faucet or valve and clearing a stoppage need no permit.²⁵ But the board says those minor repairs "do not include replacing or relocating a faucet, valve or other working part of a plumbing fixture,"²³ so a faucet swap takes a licensed plumber and a permit. Toilets, sinks, water heaters and dishwasher hookups are plumbing too, since the definition takes in "fixtures, fixed appliances."

Gas

Gas fitting covers the piping past the meter and "the connection therewith and testing of gas fixtures, ranges, refrigerators, stoves, water heaters, house heating boilers, and any other gas using appliances."²² A gas range hookup or a gas water heater goes to a licensed gas fitter, or to a licensed plumber, who may do gas fitting as well.²²

Bath fans and ductwork: the sheet metal board

This one catches remodelers. The sheet metal board's interpretation: "All residential fans and associated ductwork shall be installed by a licensed sheet metal worker. New installations shall require a sheet metal permit and inspection. The replacement of an existing residential fan shall be considered a minor alteration and will not require a sheet metal permit." The one exception: "combination fan/light units may be installed by a licensed electrician."²⁶ The statute's own definition of sheet metal work names "kitchen vents, bathroom exhaust vents and fans."²⁷

Heating, AC and heat pumps

Installers of central heating and air-conditioning are exempt from the HIC registration,⁴ which says nothing about who may do the work. A heat pump or mini-split needs an electrician for the wiring and an EPA-certified technician for the refrigerant. Federal rules require anyone "who could be reasonably expected to violate the integrity of the refrigerant circuit" to pass a certification exam, and since 2018 that covers the substitute refrigerants in today's heat pumps too.²⁸ Gas furnaces and boilers need a gas fitter. One correction to a common claim: the state's own refrigeration technician license applies to systems of "a ten ton capacity, or greater,"²⁹ so it doesn't reach a typical house.

What you can still do on those jobs is everything around them: build and set the vanity, tile, frame and patch the wall after the electrician, paint. Hire the licensed sub, make sure they pull their own permit, and remember that under Chapter 142A your subcontractors' conduct on the job counts as yours.³⁰

Lead paint and asbestos: two more licenses

Lead: Massachusetts runs its own program

EPA's lead-safe firm certification doesn't apply in Massachusetts; EPA sends contractors here to the state program.³¹ The Department of Labor Standards (DLS) licenses "Lead-Safe Renovation Contractors," and its list of who needs the license reads like your trade: "painters, plumbers, electricians, window installers, general contractors, property maintenance workers, and remodelers."³²

The rule reaches paid work in homes built before 1978 that disturbs "greater than six square feet of painted surface per room on the interiors of buildings or greater than 20 square feet of painted surface on the exterior of a building or involves window replacement or demolition of painted surfaces."³² When it applies, your business needs the DLS license ($375 on DLS's fee table), a person with a current Lead-Safe Renovator-Supervisor or Certified Renovator certificate "must be on site and in control of the work at all times," your workers need training, and the homeowner gets the Renovate Right pamphlet before work starts. DLS enforces with civil administrative penalties.³²

Six square feet is a patch about two feet by three. A remodeler on r/Contractor (state not given) showed how these cases start: "I'm a one man remodeling business. I recently got caught scraping and painting a small area on pre 1978 house. They want to meet with me and go over all the jobs I've done in pre 1978 houses last year." The first reply: "Your competitor who is EPA RRP compliant turned you in."³³

Asbestos: a survey before you tear out

MassDEP's asbestos rule is stricter than most contractors assume. Before demolition or renovation in a building with "Suspect ACM" (asbestos-containing material), "you must retain the services of a DLS-licensed asbestos inspector to conduct a thorough inspection ... and prepare a written asbestos survey report."³⁴ The suspect list includes asphalt roofing and siding, cement shingles, vinyl floor tiles and sheet flooring, mastic, wallboard joint compound, plaster and ceiling tiles, in a building of any age. The only exception MassDEP names is a homeowner doing their own work on non-friable material in their own single-family home.³⁴

For roofers and siding crews that means a survey before you tear off asphalt shingles, and if the material is asbestos (or you presume it is), a notification to MassDEP at least ten working days before removal starts.³⁴ For remodelers it means a survey before demolition. Whether you may remove asbestos material yourself depends on the job; MassDEP's own FAQ sends that question to DLS.³⁴ Price the survey into the job.

Can I take this job? A table for Massachusetts HIC holders

"Yes" means your HIC covers it with no permit. "Yes with a permit and a CSL" means you can sell and run it once a CSL holder in the right category is on the permit and supervising. "Sub it out" means a licensed trade does it, whatever your registration.

What happens if you cross the line

Working without the registration, or after it lapses

• Criminal: a contractor who operates without a registration "knowingly, willfully, or negligently," or who "fails to renew," faces "a fine not exceeding five thousand dollars or imprisonment not exceeding two years, or both."³⁵ Negligently is enough. So is a missed renewal.
• Administrative: "operating without a certificate of registration" is a prohibited act,³⁰ and OCABR can fine you up to $2,000 per violation and suspend or revoke a registration.¹²
• Civil: "Violations of any of the provisions of this chapter shall constitute an unfair or deceptive act" under Chapter 93A,³⁰ which means the homeowner's actual damages, doubled or tripled for a willful or knowing violation, plus their attorney's fees.³⁶
• Your customer loses the Guaranty Fund, and every building permit has to say so.³⁷

Can you still collect?

Some websites say an unregistered Massachusetts contractor can't sue for payment. I didn't find that rule in Chapter 142A, and the one court decision I read went the other way, with a sting. In Groleau v. Russo-Gabriele (Superior Court, 2014), the contractor wasn't registered when he agreed to a $188,500 renovation. The judge wrote that "it does not follow that the contract is automatically unenforceable," enforced it, and gave the contractor a $1,988 judgment and his mechanic's lien.³⁸ The homeowner still won her Chapter 93A counterclaim. Because he wasn't registered, she couldn't use the state's arbitration program, and she "incurred additional attorneys fees as a result," so the court ruled she was entitled to her fees. It skipped double or triple damages only because his violations "were not willful, but were based upon an incorrect and negligent interpretation" of the law.³⁸

That's one trial-court ruling, and another judge could see it differently. The lesson I take from it: you can probably collect, and the homeowner's lawyer can probably bill you for the privilege.

Skipping the permit or the CSL

• Breaking the building code is punishable "by a fine of not more than one thousand dollars or by imprisonment for not more than one year, or both, for each such violation," and "Each day during which a violation exists shall constitute a separate offense."³⁹
• For an HIC registrant, "violation of the building laws of the commonwealth" is also a prohibited act under Chapter 142A,³⁰ which makes it a Chapter 93A claim and an OCABR matter on top of the building department's.
• For a CSL holder, "work was performed without a building permit" is grounds for suspension or revocation.³

Doing licensed trade work

• Electrical without a license: a fine of $1,000 to $1,500 for a first offense, rising to $2,000 to $2,500 or six months in jail, or both, for a third or later one.⁴⁰ Not notifying the inspector of wires: up to $500.²⁰
• Plumbing or gas fitting without a license: a fine of up to $100,²² which sounds small until the inspector orders the work stopped. Nantucket's did, and the Appeals Court let the stop order stand (it said a removal order needs an inspection first).²⁴ Groleau also cites an earlier case in which a contractor's unpermitted, unlicensed plumbing and electrical work was an injury the homeowner could sue over under Chapter 93A.³⁸
• Sheet metal work without a license: discipline from the sheet metal board.²⁶
• Lead-safe violations: DLS civil penalties.³²

Insurance

I found no Massachusetts statute that voids a liability policy for work outside your registration or license. The state's checks sit elsewhere: OCABR asks for evidence of contractor insurance when you register, and the building department wants proof of workers' comp before it issues a permit.⁷¹⁷ Your policy is a contract, though, and the description of your operations is part of it. Before you take a job your card doesn't cover, read that page of the policy or call your agent.

Where your registration number has to appear

• "Every contract, building permit and advertisement shall display the contractor's or subcontractor's certificate of registration number."³⁷ On the contract, OCABR's regulation wants it on the first page.⁷
• An ad without it is a prohibited act in its own right.³⁰ I read "any advertisement relating to home construction or home improvements" to include your website, your Google Business Profile, flyers and door hangers.
• Your truck counts. OCABR's regulation defines an advertisement to include "any interior or exterior sign or display, including on a vehicle," so the number goes on the lettering.⁷
• Work under the name you registered. "Conducting a residential contracting business in any name other than the one in which the contractor or subcontractor is registered" is prohibited,³⁰ and you have 30 days to report a change of trade name or address.³⁷
• A CSL holder has to carry the license at every site and show it to the building official on request.³ Licensed plumbers and gas fitters must put their designation and license number on every sign, listing and ad.²²

Local licenses: Boston and other towns

I found no separate contractor license in Boston. The city's Inspectional Services page sends contractors to the state: any business doing residential contracting on existing one- to four-unit owner-occupied homes "must be registered as a Home Improvement Contractor (HIC) with the state."⁴¹

The building code leaves towns one opening. They may require a license for supervising work "in those categories of building and structures for which 780 CMR 110.R5 does not require a license."³ The state's advice is to "check with the municipal building official in the city\town in which the project is located for additional licensing requirements," and it adds that "Massachusetts does not recognize out of state contractor licenses."¹⁰ I didn't check all 351 cities and towns, so call the building department before your first job in a new one.

Before the next job

• Put your HIC number on your quote template, invoices, website, Google profile and truck.
• If you don't hold a CSL, decide now who will run your permit jobs: a partner, an employee, or a CSL-holding contractor you sub them to. Then split your price list into permit-free work you can sell today and permit work that waits for that person.
• Line up a licensed electrician and a licensed plumber before a customer asks for "just one outlet."
• For homes built before 1978, either get the DLS lead-safe license and a certified supervisor, or pass the painting and window work to someone who has them.
• Before a roof, siding or demolition job, book the asbestos survey.
• Put your renewal date in the calendar. The registration runs two years, and working after it lapses carries the same penalty as never registering.³⁵
• Use a written contract on every job over $1,000. The Massachusetts contract template has every item Chapter 142A requires.

Where Deepsel fits

Deepsel is the field service software I build. It has no license field, but it has two places where your HIC number belongs: a shop-wide terms text that's copied onto every quote, and an invoice footer that's copied onto every invoice. Type "MA HIC #" and your number (and your CSL number, if you hold one) into both once, and it's on every quote and invoice after that. Customers approve quotes online and sign on screen, and you can ask for a card deposit at approval that's credited on the final invoice. Free covers 30 estimates and 30 invoices a month for your whole team, with scheduling and dispatch, quotes, invoicing, card payments and customer and equipment records; Pro is $29 a month for unlimited estimates and invoices (pricing). What it won't do: Deepsel doesn't know Massachusetts law. It won't stop you quoting a faucet swap, flag a house built before 1978 or tell you a deck needs a permit. That part is this page.

Frequently asked questions

Do you need a contractor's license in MA?

For most work on an existing home with one to four units that the owner lives in, you need a Home Improvement Contractor (HIC) registration from the Office of Consumer Affairs and Business Regulation: $150 plus a Guaranty Fund payment, no exam, renewed every two years. Any job that needs a building permit also needs a Construction Supervisor License (CSL) holder in charge of it, and electrical, plumbing, gas and sheet metal work need their own trade licenses. Massachusetts has no separate general contractor license beyond the HIC and the CSL.

Does a handyman need a license in Massachusetts?

There's no handyman license. A handyman needs the HIC registration unless the whole project is under $500 (and wasn't split up to stay under), or they work part-time and earned under $5,000 from residential contracting in the 12 months before the contract, or they work only in exempt trades such as interior painting, finished flooring, fences or landscaping. None of those exemptions covers electrical or plumbing work, work that needs a building permit, or the lead-safe rules for homes built before 1978.

How much can a handyman charge without a license in Massachusetts?

Under $500 for the whole project, counting every contract for that project and the materials you bill. The $1,000 figure you'll see quoted online is the line for a written contract, not for registration. A part-time handyman who earned under $5,000 from residential contracting in the previous 12 months is exempt as well; the test looks back 12 months from each new contract.

What is the difference between an HIC and a CSL in Massachusetts?

The HIC is a consumer-protection registration from OCABR. There's no exam, and it lets you contract for home improvement work on existing owner-occupied homes with one to four units. The CSL is a competency license from the Board of Building Regulations and Standards: three years of experience and an exam. It's required for whoever supervises work that needs a building permit. A permitted job on a customer's home usually needs both.

Can a handyman do electrical or plumbing work in Massachusetts?

No. Installing or replacing light fixtures, switches, outlets and other electrical devices for hire takes a licensed electrician, and plumbing, including replacing a faucet, takes a licensed plumber with a permit. Fixing a leaky faucet or clearing a drain needs no permit, but the plumbers' board says only a licensed professional may install, remove or repair plumbing.

What is the difference between a contractor and a handyman?

Massachusetts law doesn't use the word handyman. Anyone who sells home improvement work on an owner-occupied home with one to four units is a contractor under Chapter 142A and needs the HIC registration unless an exemption applies. In practice handyman means small jobs, and the two money exemptions (a project under $500, or part-time work under $5,000 a year) are written for small jobs.

Is it easy to get a contractor license in Massachusetts?

The HIC registration is easy: $150 plus a Guaranty Fund payment of $100 to $500, and no exam. The CSL is harder: three years of experience within the last ten, then an exam run by PSI. Trade licenses take longest. A journeyman plumber's license, for example, takes three years as an apprentice plus 300 hours of theory.

How do I renew my construction supervisor license in Massachusetts?

Through the state's online licensing portal (the Renew your CSL link on mass.gov). A new CSL lasts three years and each renewal two. You need 12 hours of approved continuing education per two-year cycle for the full CSL, 10 for the one- and two-family license and 6 for a specialty license. A late renewal costs an extra fee, and supervising work on an expired license is prohibited.

How long is a contractor liable for his work in Massachusetts?

A homeowner has six years from when a contract claim accrues to sue on it. A negligence claim for a construction defect has to be filed within three years after it accrues, and never more than six years after the work was opened to use or substantially completed and occupied. A homeowner can also file for state-approved arbitration against a registered contractor up to five years from the contract date.
