Tree service license in Hawaii

Hawaii requires a state license for at least some tree work. Hawaii's Contractors License Board (Department of Commerce and Consumer Affairs) licenses contractors. The state's consumer page says a contractor license is required for any project over $1,500 in labor and material, or any project that needs a building, electrical or plumbing permit. State tree-trimming bids ask for a valid State of Hawaii C-27 (Landscaping) and/or C-27-B tree trimming license at the time of bid and for the whole contract. We could not open the official classification list, so check the board's classification list for the exact scope of C-27B before you take a job. Checked 25 October 2026. Short explanation, not legal advice.

The Pesticides Branch of the Hawaii Department of Agriculture certifies applicators to buy and use restricted use pesticides. If your crew sprays trees with restricted use products, someone needs this certification. Ask the branch which category fits your work. Confirm the exact license category with the Hawaii pesticide program before you spray or inject trees for pay.

Tree work in Hawaii falls under the same contractor licensing system as other trades. A license is needed above $1,500 in labor and material, or when a permit is required. Licenses not renewed by the expiration date are treated as unlicensed. Check with the licensing board if a job is large or includes other construction work.

Counties and cities may have their own permits, right-of-way rules and protected or exceptional tree rules, so check with your county before removing a large tree. Check with the city or county where each job is, not only where your shop is.

General liability and workers' compensation are standard for tree work, and many customers and public bids ask for a certificate of insurance; talk to a licensed insurance agent about what you need. Talk with a licensed insurance agent who knows tree work. General information, not insurance advice.
