New York is the only large state without a single statewide contractor licensing authority for general home-improvement work, which is why a contractor who tells you they're "licensed in New York" has technically told you nothing.
Home Improvement Contractor (HIC) licensing in New York is issued at the city or county level. The five boroughs of NYC are covered by the Department of Consumer and Worker Protection (DCWP, formerly DCA). Nassau, Suffolk, Westchester, Rockland, Putnam, and Albany each run their own separate HIC registries with their own fees, exams, and renewal rules. Most upstate towns require nothing at all.
Verifying a New York contractor means knowing which of those jurisdictions the job sits in, pulling the right portal, and reading the right status field. This guide walks the three lookups that cover the bulk of the state's residential remodel market, decodes the license-status codes that matter at the NYC DCWP level, and lists the red flags that catch most homeowners who think "I checked the license" is the same answer in New York as it is in Florida.
Why "licensed in New York" is not a complete answer
New York General Business Law §770 through §776 is the state's Home Improvement Business Law — the statute that governs every residential contract over $200, requires a written agreement, mandates a three-day rescission window, and caps deposits. It applies statewide. But §771(7) explicitly defers the *licensing* of contractors to local law, which is how a single state ended up with a dozen non-reciprocal licensing regimes layered on top of one consumer-protection statute.
The practical consequence: a contractor licensed by NYC DCWP cannot legally pull permits for a kitchen remodel in Westchester without a separate Westchester County Department of Consumer Protection license. A contractor licensed in Nassau County is not licensed in Suffolk. There is no statewide reciprocity, and there is no statewide rollup database. The state attorney general can sue under §776 for deceptive practices, but the day-to-day licensing enforcement happens at the city or county level.
The NYC DCWP HIC license is the most stringent of the lot. It requires a background check, passage of a written exam, and — uniquely — a $20,000 trust fund deposit (or an approved surety bond) per licensed contractor under New York City Administrative Code §20-387. That deposit funds the DCWP Home Improvement Contractor Trust Fund, which pays homeowner claims when a licensed NYC contractor fails to perform, up to per-claim caps set by the agency. That fund is the single most consumer-friendly feature of New York's otherwise-fragmented system, and it only protects you on jobs done inside the five boroughs.
The three lookups that cover most of the state
NYC (all five boroughs) — DCWP Home Improvement Contractor. Start at nyc.gov/dcwp and use the DCWP License Search. Search by business name or license number. The record shows license status, the licensed individual's name (the HIC license is issued to a person, not a company), expiration date, the trust-fund balance backing the license, and consumer complaint history. DCWP HIC license numbers are formatted as `NNNNNNN-DCA`. If the contractor hands you a six-digit number with no `-DCA` suffix, you're looking at a NYC DOB license, not a DCWP HIC license — different thing, different scope.
NYC electricians and plumbers — NYC DOB. Master Electrician and Master Plumber licenses are not issued by DCWP. They're issued by the NYC Department of Buildings under separate qualification rules, with separate exams, and they're searchable through the NYC DOB BIS License Lookup at a810-bisweb.nyc.gov. The DOB license is the qualifying individual; the company that actually shows up at your house works under a filing representative relationship to that individual. The individual licensee is the credential — confirm the name on the DOB record matches the person whose license is being used to pull your electrical or plumbing permit.
Long Island and the Hudson Valley — county consumer affairs. Nassau, Suffolk, Westchester, Rockland, and Putnam each run separate HIC registries through their county Department of Consumer Affairs (or, in Westchester, Consumer Protection). Nassau County's portal is at the Office of Consumer Affairs license search; Suffolk's is at the Office of Consumer Affairs Licensed Home Improvement Contractor search; Westchester's is at the Department of Consumer Protection's license verification page. Each is a separate lookup. None of them reciprocate with NYC DCWP. A contractor working a Long Island job needs the relevant county license — the NYC HIC won't cover it.
How to read a NYC DCWP HIC record
The DCWP portal exposes a status field that most consumers skim past. The codes that matter are:
- Active — current, in good standing, trust-fund deposit on file. This is the only status that fully protects you under the HIC Trust Fund.
- Inactive — the licensee has paused the license, often during a renewal gap or a voluntary suspension. The contractor may not legally perform home-improvement work in NYC until the license is restored to Active.
- Expired — renewal deadline passed without action. Treat as unlicensed for any new contract.
- Suspended — DCWP has taken enforcement action, typically pending resolution of a consumer complaint or a hearing. Walk.
- Revoked — final agency action. The contractor cannot relicense without going through the full application process again, and the underlying conduct is documented in the public record.
Pull the complaint history tab too. It's a separate click on the DCWP record and it shows pending complaints, settled mediations, and any disciplinary orders. A live Active license with three open complaints is a different risk profile than a live Active license with zero — and DCWP's mandatory mediation program means most homeowner disputes against a licensed NYC contractor first land here, not in court.
Red flags that catch most New York homeowners
"Licensed in New York" without a jurisdiction. This is the single most common evasion. New York State does not issue a general home-improvement license to anyone. If the contractor cannot name the specific city or county that issued the license and produce the license number, the license does not exist as claimed. Ask for the license number, then verify it on that specific board's portal — not on Google.
A NYC DCWP license used for a Westchester or Long Island job. A contractor with a valid DCWP HIC license who's quoting a project in White Plains or Huntington is operating outside their licensed jurisdiction unless they also hold the relevant county HIC. The DCWP trust-fund protection does not follow them across the city line.
The DOB license is in a different person's name than the company. NYC DOB Master Electrician and Master Plumber licenses are personal credentials. A company can use a licensed individual as its qualifying "filing representative," but if the individual whose license is on the permit isn't actually involved in supervising your job — common when a shop's filing rep changes mid-project — you may be hiring labor with no master licensee actually overseeing the work. Ask which DOB-licensed individual will be pulling your specific permit and confirm that name on the BIS lookup.
Salesperson is licensed, installer isn't. Some larger NYC remodelers send a DCWP-licensed home-improvement salesperson to your kitchen for the pitch (HIS licenses are also issued by DCWP, separately from the HIC), then subcontract the actual demolition and build-out to unlicensed labor. The HIC license number on the contract is the one that has to be active — and the work has to be supervised by that licensee, not a different crew on a different payroll.
What the patchwork doesn't tell you
Honest about the limits, because in New York more than most states they matter.
There is no statewide rollup. A contractor disciplined by Nassau County's consumer affairs office can hold a clean record in NYC, and nothing on the DCWP portal will flag the Nassau action. Cross-jurisdiction verification is manual — you check each board separately.
Insurance status is not centrally tracked. DCWP collects proof of general liability and (where required) workers' compensation at issuance and renewal, but the portal does not surface live coverage status. Coverage can lapse mid-cycle. Ask for a current Certificate of Insurance naming your address as the certificate holder, then call the insurer to confirm.
Mechanic's-lien history lives at the county clerk. A contractor with a clean DCWP record can still have a string of mechanic's liens filed against prior clients' properties — those are recorded with the county clerk where the property sits (NY County for Manhattan, Kings for Brooklyn, etc.) and don't surface in any licensing portal.
Out-of-state contractors operate under temporary registrations. New Jersey or Connecticut contractors taking on a NYC job typically register temporarily with DCWP rather than getting a full HIC license. Their home-state license is not verified by DCWP — you have to pull the underlying NJ or CT credential separately.
Sourcing licensed New York contractors at scale
ContractorRoster maintains a continuously-updated mirror of New York's licensed-contractor data with phone, email, website, and Google ratings layered in. Because NY licensing is fragmented, our coverage focuses on the jurisdictions where centralized data exists — NYC DOB (general contractors, electrical, plumbing, HVAC, fire-suppression), NYC DCWP (Home Improvement Contractors), and the City of Buffalo registry — for a combined 28,981 active records, roughly 4.6% of the 629,594 active licenses we mirror across 13 states.
For one-off verification of a name you've already been handed, the relevant city or county portal above is the right tool — it's the source of truth, and in New York it's the only source of truth. For sourcing multiple licensed contractors at scale — a property manager building a vendor roster across the five boroughs, a supplier launching into the New York metro, a developer running an RFP across a multi-property NYC rehab — our $39 CSVs at /newyork pull the same DCWP, DOB, and Buffalo data pre-enriched with the contact info those portals don't publish.
Either way, the verification rules above don't change. Even from a pre-enriched roster, the last check before you sign is to pull the license on the relevant board's portal and read the status code yourself.
