A market guide for independent insurance agents. Last reviewed: June 2026.
The most expensive mistake in tree care is writing it as landscaping: standard landscaping GL forms cap work at roughly 8-10 feet, leaving a climber-based business effectively bare. True arborist GL is mostly non-admitted, and workers comp code 0106 is among the most avoided classes in the market — in California, only about 1% of the WC market will consider tree trimming.
Two programs dominate: ArborMAX (the TCIA's endorsed program, with arborist E&O and pesticide coverage) and NIP Group's TreePro (crane/boom, utility line clearance, wildfire liability, excess to $25M). Small accounts below program minimums get assembled piecemeal.

Real placement discussions from independent agents about tree service & arborist insurance.
Small operations typically see $1,500-$1,800/yr for $1M limits through E&S; program business (TreePro) reportedly starts around $10K total account minimums. Sub-minimum startups get assembled from Progressive auto + E&S GL.
AmeriSafe, state funds, NIP TreePro's WC programs, and ArborMAX (TCIA members with accreditation or a CTSP). In tough states the PEO route is often the practical answer.
Usually not above ~8-10 feet. If the insured climbs or uses a crane, the form must explicitly cover tree work at height — otherwise there is no coverage for the core operation.
