Contractor Licensing by State
Does New York license general contractors?
No. New York State does not license general contractors. Here is what the state actually regulates, what your city requires on top, and what to check when there is no license to check.

The Department of State licenses 35 occupations and not one of them is a construction trade. In New York even electricians and plumbers are licensed locally rather than by the state. Where a home improvement contractor needs a licence at all, it is New York City or one of five downstate counties that issues it -- and across most of the state's map, nobody issues one.
“Home improvement contractors must be licensed in New York City, Suffolk, Nassau, Westchester, Putnam, and Rockland counties.”
— Suffolk County Department of Labor, Licensing and Consumer Affairs, Home Improvement Fact SheetWhat New York does license
New York State does license a short list of construction specialities. All of them sit with agencies other than the Department of State, and none of them is a general contractor or home improvement licence.
Asbestos handling
Article 30 of the Labor Law. The Department of Labor's License and Certification Unit issues an Asbestos Handling Licence to contractors and Certificates of Competence to the individuals doing the work. The same unit issues Crane Operator and Blaster certificates, explosives licences, laser operator certificates and pyrotechnician certificates. Official page →
Mold assessment and remediation
Article 32 of the Labor Law. The Department of Labor states that it is unlawful for any person to engage, advertise or hold themselves out as a mold assessor, remediation contractor or abatement worker without a valid mold licence. The programme also forbids the same person from both assessing and remediating the same property, and requires an independent assessment to define the scope of the work. Official page →
Elevators, lifts and conveyances
Article 33 of the Labor Law -- the Elevator Safety Act -- licenses elevator contractors, inspection contractors, mechanics, inspectors and accessibility lift technicians. Only licensed mechanics working under a licensed contractor may do the work. Two changes land on 10 June 2026: a temporary mechanic licence for verified shortages, and the end of the pre-2022 work-experience route to qualification. Official page →
Home inspectors -- who are not contractors
The Department of State does license home inspectors, along with real estate brokers, appraisers and security or fire alarm installers. It is worth knowing because the inspector you hire to check a contractor's work is state-licensed even though the contractor is not. Official page →
Public work contractors -- registration, not licensure
The Department of Labor runs a Public Work Contractor and Subcontractor Registry. It applies only to construction on public work projects or private projects covered by Article 8 of the Labor Law. It has nothing to do with work on your house, and a contractor citing it at you is citing the wrong thing. Official page →
What it does not
None of these carries a New York State licence. Some are licensed by a city or a county; several are licensed by nobody:
- General contracting
- Home improvement
- Electrical work
- Plumbing
- Roofing
- HVAC
- Masonry and concrete
- Carpentry
- Drywall
- Painting
City rules, which is where it actually bites
In New York the line that matters is the county line, and only six jurisdictions have drawn one. What “licensed” means differs sharply between them, and outside them the word has no local meaning at all.
New York City
The Department of Consumer and Worker Protection licenses Home Improvement Contractors, and the licence is required for any home improvement job costing more than $200 on a residential building. Getting one means fingerprinting through IdentoGO, a written examination, workers' compensation cover, EPA lead certification, and either a $20,000 surety bond or enrolment in DCWP's Home Improvement Trust Fund. Operating without one can be prosecuted as a misdemeanour, and DCWP can padlock the business and confiscate its tools and trucks. Watch the boundary: new home construction, plumbing and purely electrical work are not “home improvement” and are covered by different credentials. Official page →
New York City, the other credential
DCWP's licence covers repairs and remodelling. Building a new one-, two- or three-family house is a different gate entirely: those contractors must hold a General Contractor Registration with the Department of Buildings before New Building permits can be issued to them. It runs three years and is renewed with the Buildings Department, not DCWP. Two agencies, two credentials, and a contractor can hold one without the other. Official page →
Nassau County
The Department of Consumer Affairs licenses home improvement contractors under Section 21-11 of the county's Administrative Code. Applicants need five years of recent verifiable experience, fingerprinting, liability and workers' compensation certificates, and a real business location in New York State -- the county says an answering service does not count. Commercial-only contractors are exempt, as are plumbers, electricians, architects and engineers working inside their own licensed field. Working unlicensed is a Class A misdemeanour, with seizure of vehicles and tools. Nassau also runs a Home Improvement Restitution Fund capped at $10,000 -- and it pays out only against licensed contractors. Official page →
Suffolk County
Licensed by the Department of Labor, Licensing and Consumer Affairs under Chapter 563 of the county code, on top of Article 36-A of the General Business Law and Section 71-a(4) of the Lien Law. The county is unusually direct about what the licence buys a homeowner: it will mediate a dispute with a licensee, and homeowners holding an uncollectable judgment or arbitration award against a licensed contractor may be entitled to compensation from Suffolk's Restitution Fund. Neither is available against a contractor the county never licensed. Official page →
Westchester County
The Department of Consumer Protection licenses home improvement contractors, and separately runs examination-based plumbing and electrical licences through its own Plumbing and Electrical Boards. Licensed contractors carry a department-issued card and a vehicle decal showing the expiry date. Contractors working in Yonkers must additionally be licensed by that city's own Consumer Protection Bureau. Westchester publishes two lists: who is licensed, and a “Renegade Renovators” list of unlicensed contractors it says are the source of many consumer complaints. Official page →
Putnam County
Putnam's Consumer Affairs office runs what it calls a mandatory contractor registration programme, and states its purpose plainly: to assure that contractors working on residential properties in the county are insured, bonded and carrying workers' compensation. It publishes a dated list of registered contractors, and separately operates a Home Improvement Board, an Electrical board and a Plumbing/Mechanical Trades Board. Official page →
Rockland County
The Office of Consumer Protection licenses home improvement, electrical and mechanical contractors and publishes the lists. In April 2026 the County Legislature overhauled a law that had seen few significant changes since 1984: licensing authority moved from the volunteer Licensing Board to the Director, the county now has 45 days to notify an applicant of missing paperwork or other problems and the licence is automatically deemed approved if it does not, general contractors must use licensed and properly insured subcontractors, and contractors using the new expedited pathway must post a bond. If you are reading older guidance about Rockland, it is describing a law that no longer applies. Official page →
A New York licence proves the law was studied, not that the work will be good
New York's licensing counties vet harder than most states -- fingerprints in New York City and Nassau, five years of verifiable experience in Nassau, background checks in Westchester. But read what the examination actually tests. New York City's own Home Improvement Examination Guide sets out four sections: the city's home improvement business law, contracts and cancellations, advertising and selling practices, and general industry and business knowledge. Not one of them is about building. A DCWP licence certifies that somebody at the company passed a law-and-business exam, cleared a background check and posted a bond or paid into the trust fund. It does not certify that anyone there can frame a wall. Westchester makes the same point about the shortcut most homeowners take instead, warning that online contractor referral services may not properly or completely vet the companies they promote, may not verify whether a listed contractor holds a required licence, and may not check whether complaints have been filed.
What to check instead
New York gives homeowners more to work with than most no-licence states, but the tools are scattered across six jurisdictions and two state agencies. Take them in order.
- Work out which jurisdiction you are in -- then check that oneThere is no statewide contractor database, because there is no state licence to record. New York City, Nassau, Suffolk, Westchester, Putnam and Rockland each run their own register on their own terms. If your property is anywhere else in New York, there is probably no licence to check at all, and everything below carries the weight instead.
- Read the status field, not just whether a record existsNew York City publishes its licence file as open data, and it holds thousands of expired, surrendered and revoked Home Improvement Contractor records alongside the active ones. A search that returns a hit is not the same as a search that returns an active licence. Check the status and the expiry date -- New York City licences expire on 28 February of odd-numbered years, so a lapse is easy to miss.
- Look at the two published lists of contractors to avoidThis is New York's most under-used homeowner tool and it costs nothing. DCWP maintains a Wall of Shame naming every home improvement business that received a violation for operating without a city licence in the last twelve months. Westchester maintains its Renegade Renovators list of unlicensed home improvement contractors, plumbers and electricians it urges residents to avoid. Both name names.
- Verify workers' compensation with the Board, not with a certificateUnlike Texas, New York requires workers' compensation for almost everyone employed here -- and the Workers' Compensation Board runs a free Employer Coverage Search fed daily by insurers' own proof-of-coverage filings. That is a live check against the insurer's records rather than a PDF the contractor emailed you. If the employer does not appear, the Board takes reports.
- Ask where your deposit will be held -- the law already requires an answerUnder Section 71-a of the Lien Law, a home improvement contractor anywhere in New York must deposit payments received before substantial completion into an escrow account at a New York banking institution within five business days, or hand you a bond, contract of indemnity or irrevocable letter of credit instead. If the contract does not name the depository, the contractor has ten business days to tell you in writing where your money is. Failing to escrow customer deposits is itself a violation, and this applies statewide, licence or no licence.
- If it is a roof, read the contract against Section 771-bNew York put statewide rules on roofing contractors without ever licensing them. A roofing contractor must have a written contract naming its insurer, the type of cover and the policy limits; may not require a deposit; may not offer to pay or rebate any part of your insurance deductible; and may not report, adjust or negotiate an insurance claim for you. Where the local government sets no insurance requirement, the statute sets the floor. A roofer asking for money up front is out of step with the statute, not just with good practice.
- Make the contractor pull the permit in their own nameNew York City's own guidance for licensees says it is the duty and obligation of the prime contractor to secure all necessary permits, licences and certificates of occupancy, and that a contractor may not shift that responsibility to the consumer. Anywhere in the state, a contractor asking you to pull the permit is moving liability onto you, and often doing it because they cannot pull it themselves.
New York's lien risk is real, but it is capped -- and the cap is the point
Under Article 2 of the Lien Law an unpaid subcontractor, labourer or material supplier can file a mechanic's lien against your home. New York differs from most states in one decisive way. Section 4 says that in no case shall the owner be liable, by reason of all liens created under the article, for a sum greater than the value or agreed price of the labour and materials remaining unpaid at the time the notices of lien are filed. If you genuinely owe your contractor nothing, there is generally nothing for the subcontractors' liens to attach to -- which is exactly why the payment paperwork decides the outcome.
- The cap only protects you if you can prove what you paid and when. Collect a signed lien waiver at every payment and keep them together.
- The filing clock is shorter for houses. A notice of lien on property improved with a single family dwelling must be filed within four months of completion, against eight months for everything else.
- A filed lien lasts one year. On a single family dwelling it can only be extended by an order of a court of record -- the lienor cannot simply file an extension the way they can on other property.
- Your contract is required to warn you. Section 771 of the General Business Law makes a bold-face mechanic's lien notice mandatory, and it tells you in terms that payment of the agreed-upon price before a lien is filed may invalidate that lien.
- The same section requires the contract to tell you that the contractor must escrow your pre-completion payments under Section 71-a of the Lien Law, or post a bond or letter of credit with you instead. If that notice is missing from your contract, the contract is non-compliant before the first nail goes in.

New York has no right-to-repair step for remodels -- new homes are different
If a renovation goes wrong in New York there is no equivalent of the Texas notice-and-inspection process: nothing requires you to give the contractor a chance to cure before you sue. New construction is another matter. Article 36-B of the General Business Law implies a housing merchant warranty into the sale of a new home -- one year against defects from a failure to build in a skillful manner, two years on the plumbing, electrical, heating, cooling and ventilation systems, six years against material defects. To use it you must get written notice of the warranty claim to the builder before commencing any action, and no later than thirty days after the applicable warranty period expires, and you must give the builder a reasonable opportunity to inspect, test and repair.

How to verify what can be verified
What you can actually check in New York, and what each one proves.
| NYC DCWP licence search | Free | The official check for a New York City Home Improvement Contractor licence. Covers DCWP-licensed businesses only -- not new-home builders, plumbers or electricians, who are licensed by the Buildings Department. |
| NYC DCWP Wall of Shame | Free | Every home improvement business that received a violation for operating without a DCWP licence in the last twelve months, listed by name. Read it before you sign anything in the five boroughs. |
| NYC Buildings licence and registration search | Free | The city's own credentials: General Contractor Registration, electricians, master and journeyman plumbers, hoisting machine operators, riggers, construction superintendents and the rest. |
| NYC Open Data -- Issued Licenses | Free | The DCWP licence file, downloadable and filterable. More useful than the search box because it carries licence status and expiry side by side, so you can see how much of the file is inactive. |
| Nassau County licence lookup | Free | Home improvement and other Nassau licences. The department will also give a firm's complaint history by phone, which the online lookup does not show. |
| Westchester licensed contractors and Renegade Renovators | Free | Two lists from one department: who holds a county home improvement, plumbing or electrical licence, and who the county says to avoid. |
| Putnam County registered contractors | Free | A dated list of contractors registered with the county's Consumer Affairs office. The date on the list matters -- check it. |
| Rockland County licensed businesses | Free | Home improvement, electrical and mechanical licensees, published by the Office of Consumer Protection. |
| NYS Workers' Compensation Board coverage search | Free | Confirms an employer's workers' compensation, disability and Paid Family Leave cover from insurers' own proof-of-coverage filings, updated daily. The strongest free check in New York. Coverage before 1 January 2002 is not in it. |
| NYS Department of State entity search | Free | Confirms a corporation or LLC exists and is on file. It says nothing about competence, insurance or licensing, and nothing about whether the entity on the certificate is the one that will do your work. |
Three things people get wrong
“New York licenses contractors.”
New York City does, and five counties do. The State of New York does not, and most of its counties do not either. Outside those six jurisdictions there is no home improvement licence to hold, to check, or to lose -- which also means there is no licence a bad contractor can be stripped of.
“My contractor is licensed by New York State.”
There is no such licence for building work. If a contractor shows you a New York State credential, read what it is actually for. It may be a Department of Labor asbestos, mold or elevator licence, a Department of State home inspector licence, or the Department of Labor's public work contractor registration -- which is required only for prevailing-wage public projects and has nothing to do with your house.
“Unlicensed contractors are illegal in New York.”
It depends entirely on where the work is and what it is. Home improvement work over $200 without a DCWP licence in New York City can be prosecuted as a misdemeanour, and working unlicensed in Nassau is a Class A misdemeanour with seizure of vehicles and tools. The same work in most of upstate New York breaks no licensing law, because there is no licence. What is unlawful everywhere in the state is mold, asbestos and elevator work without the relevant Department of Labor licence.
Reviewed August 2026. Licensing rules change — Check the six licensing jurisdictions separately rather than assuming they still match each other -- Rockland rewrote its home improvement law in April 2026, and the state's elevator licensing rules change again on 10 June 2026.
