Quick answer: New York has no statewide contractor or home-improvement license for most trades. Licensing happens at the city or county level — for example, New York City licenses master plumbers and master electricians through the Department of Buildings (DOB) and home improvement contractors through the Department of Consumer and Worker Protection (DCWP), while counties like Nassau, Suffolk and Westchester license home improvement contractors (and Westchester also licenses plumbers and electricians). The NY Department of State does not license construction trades. Always check the rules for your specific city or county.
Here is which trades typically need a license in New York and who issues it — remember that requirements are local, so confirm with your city or county.
Which trades need a license in New York?
| Trade | State license required? | Licensing body |
|---|---|---|
| Plumber | Local | No state license. Licensed locally — e.g. NYC DOB (Licensed Master Plumber) and Westchester County. Many other localities require a local plumbing license too. |
| Electrician | Local | No state license. Licensed locally — e.g. NYC DOB (Master/Special Electrician) and Westchester County; many towns and counties also license electricians. |
| HVAC | Local | No statewide HVAC license. Requirements vary by locality; residential HVAC replacement/repair is often treated as home improvement, requiring a local home improvement contractor license. |
| General Contractor | Local | No state GC license. Residential remodeling generally requires a local Home Improvement Contractor license (NYC DCWP; Nassau, Suffolk, Westchester and other localities). |
| Roofer | Local | No state license. Residential roofing is home improvement work, so a local Home Improvement Contractor license (NYC DCWP or your county) typically applies. |
| Painter | Local | No state license. Residential painting is home improvement work — a local Home Improvement Contractor license usually applies, plus EPA RRP lead certification on pre-1978 homes. |
| Carpenter | Local | No state license. Finish/remodeling carpentry on homes is home improvement work, so a local Home Improvement Contractor license generally applies. |
| Landscaper | Local | No state license. Landscaping, patios, driveways and fences count as home improvement in NYC and many counties, so a local Home Improvement Contractor license typically applies. |
| Handyman | Local | No state license. Paid repair/remodeling on residences is home improvement work — NYC and many counties require a local Home Improvement Contractor license even for small jobs. |
| Cleaner | No | No state or typical local license for house or office cleaning. General business registration may still apply; check your city or county. |
Licensing in New York is local, not statewide — a trade may be unlicensed in one town and require a license in the next, so always confirm with your city or county before you work.
How New York handles contractor licensing
New York is unusual: there is no single statewide contractor license for most construction trades. The New York Department of State's Division of Licensing Services licenses occupations such as real estate agents, cosmetologists, notaries and security guards — but not plumbers, electricians, general contractors, roofers, painters or home improvement contractors. Instead, trade and home-improvement licensing is handled at the city and county level, so the rules depend entirely on where the work is performed.
New York City: DOB and DCWP
New York City has the most developed licensing system. The NYC Department of Buildings (DOB) issues the Licensed Master Plumber and Master/Special Electrician licenses, each requiring years of documented experience plus written and practical exams. Separately, the NYC Department of Consumer and Worker Protection (DCWP) issues the Home Improvement Contractor license, required for construction, repair, remodeling and related work on residential property — including basements, driveways, fences, garages, landscaping, patios, porches, roofing and more.
Long Island and Westchester counties
Suburban counties run their own consumer-affairs licensing. Nassau County (Office of Consumer Affairs, under Administrative Code §21-11) and Suffolk County (Office of Consumer Affairs) both require a Home Improvement license to operate a home improvement business — Suffolk notes it is against the law to do so without one. Westchester County (Department of Consumer Protection) goes further: it licenses home improvement contractors and also issues trade licenses for plumbers and electricians, and requires all electrical and plumbing work to be done by a county-licensed tradesperson.
The home-improvement-contractor rule
Across New York's localities, the most common requirement is a Home Improvement Contractor (HIC) license for paid work on residential property. Trades without their own dedicated license — general contractors, roofers, painters, carpenters, landscapers and handymen — usually fall under this HIC umbrella when the job is residential. HIC licensing typically requires insurance and workers' compensation coverage, and often a surety bond or trust-fund enrollment and a passing exam (in NYC, through DCWP).
State registration vs. licensing
Do not confuse licensing with the state contractor registry. Effective December 30, 2024, the NY Department of Labor requires contractors and subcontractors bidding or working on public works and certain covered private projects (under Labor Law Article 8) to register — a $200 registration, not a trade license, and it does not apply to ordinary private residential jobs.
How to get licensed in New York
- Identify the city or county where the work will be performed — New York licensing is local, so this determines every requirement that applies to you.
- For work in New York City, apply through DOB NOW for a Master Plumber or Master/Special Electrician license (DOB), or apply to NYC DCWP for a Home Improvement Contractor license for residential remodeling.
- For Nassau, Suffolk or Westchester, contact the county Office of Consumer Affairs / Department of Consumer Protection to obtain a Home Improvement Contractor license (and, in Westchester, a plumbing or electrical trade license).
- Gather the standard prerequisites: general liability insurance, workers' compensation coverage (or an exemption), any required surety bond or trust-fund enrollment, and EPA RRP lead certification if you disturb paint in pre-1978 homes.
- If you will bid on public works or covered private projects, also register with the NY Department of Labor contractor registry, and pass any required city/county licensing exam before you begin work.
