New York does not issue a statewide general contractor license. Contractor and trade licensing is handled at the municipal or county level. Which license you need depends on where the work is, not what trade you are in. Working in New York City, Buffalo, and Suffolk County can mean 3 different licensing regimes for the same trade. General contractor / home improvement. - New York City. Department of Consumer and Worker Protection (DCWP, formerly DCA) issues the Home Improvement Contractor license for residential remodeling. Commercial construction in NYC is governed by separate Department of Buildings (DOB) filing and insurance requirements. Salespersons also need a separate Home Improvement Salesperson license. - Nassau County, Suffolk County, Westchester County, Rockland County, and many towns and villages each run separate home improvement contractor licensing regimes. - Upstate cities (Buffalo, Rochester, Syracuse, Albany) each have local contractor registration requirements that vary by city. Electrical licensing. - New York City. DOB issues the Master Electrician and Special Electrician licenses. Licensing is local to NYC and does not transfer. - Buffalo, Rochester, Syracuse, Yonkers, White Plains, and other cities each maintain their own electrical examining boards. - There is no single statewide electrician license in New York. If you work across city lines you may need multiple licenses. Plumbing licensing. - New York City. DOB issues the Master Plumber license. Only a licensed Master Plumber can pull a plumbing permit in the city. - Other cities and counties run their own plumbing examining boards. What to do before you bid. 1. Identify every municipality where you intend to work. 2. Check each municipality's licensing page and confirm whether your trade requires a license there. 3. Budget for multiple applications, exams, and renewal cycles if you plan to work across several markets. 4. For NYC work, pay close attention to DCWP trust fund and bond requirements for home improvement contractors, and to DOB continuing education and insurance requirements for electricians and plumbers. Work performed without the required local license is not enforceable in court in most New York jurisdictions, and exposes the contractor to civil penalties. Confirm the specific local license before you advertise or bid.
