Tree service license in New Jersey

New Jersey requires a state license for at least some tree work. Under New Jersey's Tree Experts and Tree Care Operators Licensing Act, at least one person in each company that hires itself out for tree care services must be licensed, and the business must register with the Board of Tree Experts. A Licensed Tree Care Operator can do pruning, brush cutting or removal, tree removal and stump grinding or removal. A Licensed Tree Expert can also do consulting, diagnosis and treatment, fertilization, cabling and bracing, lightning protection, risk assessment and pesticide application. Businesses must have a licensee assigned to the main office and each branch, carry workers' compensation and general liability insurance, and train employees in safety. Rules can change, so check the Board for current rules. Checked 25 October 2026. Short explanation, not legal advice.

The New Jersey Department of Environmental Protection certifies commercial pesticide applicators. Rutgers, which runs the training, says you pass a core exam and a category exam; Category 3A (Ornamental) covers pest control in the maintenance and production of ornamentals, and Rutgers points tree spraying to 3A. Ask NJDEP whether your business also needs a pesticide business license. Confirm the exact license category with the New Jersey pesticide program before you spray or inject trees for pay.

New Jersey's Contractor's Registration Act requires home improvement contractors to register with the Division of Consumer Affairs and show their NJHIC number. The state's quick start guide (dated May 2019) lists proof of commercial general liability insurance of at least $500,000 per occurrence and a $110 fee. Ask the Division whether your tree work counts as home improvement. Check with the licensing board if a job is large or includes other construction work.

Many New Jersey towns have tree removal permits and shade tree commissions with their own rules, so check with the town before you bid. Check with the city or county where each job is, not only where your shop is.

New Jersey's tree law requires registered tree businesses to carry workers' compensation and general liability insurance; ask the Board for the current minimums and a licensed insurance agent about what fits your work.
