Visit official lookupAbout New York contractor licensing
New York does not issue one statewide general contractor license for home improvement or residential remodeling. Instead, licensing is heavily municipal. That means homeowners need to focus on the city or county where the property is located, with New York City, Westchester, Nassau, and Suffolk all using notable local systems that do not automatically substitute for one another.
How licensing works in New York
New York is one of the clearest examples of local contractor regulation. New York City has its own Home Improvement Contractor license through DCWP, while counties such as Westchester, Nassau, and Suffolk maintain separate systems. Many upstate municipalities handle things differently or rely more on local permit processes. For homeowners, there is no single statewide contractor search that solves the problem. The right verification path is to identify the exact local jurisdiction first and then verify any state-regulated trades separately.
What to verify in New York
Start with the local licensing authority where the property sits, not just the contractor's office location. In New York City, verify the Home Improvement Contractor license through the city's consumer affairs system; in Nassau, Suffolk, and Westchester, use the county's own contractor resources. Confirm the license is active and that the legal business name matches the contract exactly. Then separately verify any state-regulated trades or permit-related credentials tied to the work.
State-specific tips
- › If the property is in New York City, use the NYC Home Improvement Contractor system, not a generic state business search.
- › A contractor licensed in Nassau is not automatically cleared for Suffolk, Westchester, or NYC work.
- › Ask which local license applies to your exact property address before you compare bids.
- › For co-ops and condos, verify both the public license record and any building-specific contractor requirements.
- › If the contractor advertises licensed in New York, ask them to name the exact city or county license you should verify.

Frequently Asked Questions
- Does New York require general contractors to be licensed statewide?
- No. New York State does not issue a statewide general contractor license. Licensing and registration requirements for general contractors are set at the local level — they vary significantly by city and county. New York City has one of the most rigorous local systems in the country through the NYC Department of Buildings (DOB). Nassau, Suffolk, and Westchester counties each have their own home improvement contractor licensing requirements. Outside those jurisdictions, requirements vary further by municipality.
- How do I verify a contractor is legitimate in New York without a state license to check?
- Start by verifying the business entity with the New York Department of State at dos.ny.gov. For NYC projects, check the contractor's DOB license and registration at nyc.gov/buildings. For Nassau County, verify the Home Improvement Contractor license at nassaucountyny.gov. For Suffolk and Westchester, check the respective county licensing portals. Always verify general liability insurance and workers' compensation directly with the insurer — New York's workers' comp enforcement is strict, and gaps in coverage expose you to significant liability.
- Are specialty trade contractors licensed in New York?
- Yes, but licensing varies by jurisdiction. Plumbers in New York City are licensed through the NYC DOB; outside NYC, plumbing licensing is generally local. Electricians are licensed locally — NYC has its own electrical licensing through the DOB, while other areas follow county or city rules. HVAC contractors are not licensed at the state level but may require local registration. Always verify specialty trade credentials with the relevant local licensing authority for your specific address, not just the state.
- Does my city or county require contractors to be licensed in New York?
- The major jurisdictions all do. New York City requires Home Improvement Contractor (HIC) registration for work over $200, administered by the NYC Department of Consumer and Worker Protection (DCWP) — verify at nyc.gov/dcwp. Nassau County requires a Home Improvement Contractor license — verify at nassaucountyny.gov. Suffolk County requires a Home Improvement Contractor license — verify at suffolkcountyny.gov. Westchester County has its own contractor licensing system. For upstate or rural areas, contact your local building department to confirm what applies.
- What insurance should I require from a contractor in New York?
- New York law makes workers' compensation mandatory for contractors with employees — it is one of the most strictly enforced states in the country. If a contractor's employee is injured on your property and the contractor has no workers' comp, you can be held liable as the de facto employer. Always require a Certificate of Workers' Compensation Insurance (Form C-105.2) and a Certificate of General Liability Insurance before work begins. Verify both directly with the insurer — do not accept photocopies or screenshots.
- Is a written contract required for home improvement work in New York?
- Yes. New York General Business Law §771 requires a written contract for home improvement work of $500 or more outside New York City. The contract must include the contractor's name and address, a description of the work, the total price, payment schedule, and estimated start and completion dates. In New York City, NYC Admin Code §20-386 et seq. imposes additional requirements for HIC-registered contractors. Contracts that fail to meet these requirements may be voidable by the homeowner.
- What recourse do I have if a contractor does poor work or abandons my project in New York?
- New York General Business Law §349 prohibits deceptive acts and practices in consumer transactions — violations allow homeowners to recover actual damages plus attorney fees. GBL §771 provides specific protections for home improvement contract violations. File a complaint with the New York Attorney General's Consumer Frauds Bureau at ag.ny.gov. NYC homeowners can also file with the NYC DCWP. For disputes under $10,000, Small Claims Court is an accessible option. For licensed contractor violations in NYC, the DOB handles disciplinary action.
- Where do I find contractor requirements for my city or county in New York?
- Start with the building or permits department for your specific address. For New York City, use the NYC DOB at nyc.gov/buildings and NYC DCWP at nyc.gov/dcwp. For Nassau County, visit nassaucountyny.gov/agencies/buildings. For Suffolk County, visit suffolkcountyny.gov/departments/laborlicensingconsumeraffairs. For Westchester County, visit westchestergov.com. For upstate municipalities, search '[your city or town] building department contractor license' — most post requirements online or can be reached by phone.
