State rules · New York
No state tree license found
We could not find a New York State license for tree trimming or tree removal. Any commercial pesticide application needs New York State DEC certification, and a business that offers pesticide services for hire must register with DEC. Some local governments license home improvement work, and New York City lists landscaping as covered work. Short explanation, not legal advice.

No state tree license found
We could not confirm a state-level tree service or arborist license in New York. The state rule we did confirm is pesticide certification from the Department of Environmental Conservation. Local rules matter a lot here: for example, New York City's home improvement contractor license covers work on residential land and names landscaping, and other cities, counties or villages may have their own rules. Check with the state and your city or county.
DEC says certification is required to apply any pesticide commercially. A Certified Commercial Pesticide Applicator can use and supervise general-use and restricted-use pesticides. A Certified Commercial Pesticide Technician can use general-use pesticides without supervision. A Commercial Pesticide Apprentice is not certified and must work under a certified applicator's direct supervision. A business that offers pesticide services for hire must be registered with DEC's Bureau of Pesticides Management.
We did not find a general New York State contractor license that covers tree work. Home improvement licensing can be handled by local governments. New York City, for example, requires a home improvement contractor license for work on residential land or buildings in the city and lists landscaping as covered work. Ask your local consumer affairs office whether tree work on homes is covered where you work.
Cities, counties and villages in New York can require their own licenses, street tree permits and tree removal permits, so check with the local government where each job is before work starts.
Check with the city or county where each job is. Homeowners often ask about this too; you can send them our plain guide to tree permits.
Most tree companies carry general liability and workers' compensation, and local licenses and many customers ask for proof of insurance. Talk to a licensed insurance agent about what your business needs.
General information, not insurance advice. Talk with a licensed agent who knows tree work. More in insurance for tree services, or rough your cost with the workers comp estimator.
