Tree work is hard to insure. I place it.
General liability, workers' comp, equipment and commercial auto for tree trimming, removal and arborist businesses, from one-truck operators to crane crews.
Quick answer A tree service business needs general liability, workers' comp, equipment and commercial auto coverage, set up for its trimming, removal or arborist work, from one-truck operators to crane crews.
- General liability for a tree service is designed for damage to homes, cars and property from falling trees and limbs.
- Workers' comp for tree crews is among the most expensive classes in California, because climbing and chainsaw work bring serious injury risk.
- Many standard carriers exclude tree work because of large property claims and high injury rates; specialty markets write it, priced on height, crane use and the work done.
- Crane and bucket truck work must be disclosed to the insurer, because underwriters ask about it and rate for it.

Why carriers turn tree work away
A falling limb can land on a house, a car or a power line, and climbing and chainsaw work bring serious injury risk. Many standard carriers won't write tree work at all, and workers' comp for tree crews is among the most expensive classes in California.
I work with the specialty markets that do write it, and set the coverage up around how you actually work: height, crane use, removal versus trimming, and whether you work near power lines.
- General liabilityDamage to homes, cars and property from falling trees and limbs.
- Workers' compClimbing, chainsaw and chipper injuries.
- EquipmentChippers, stump grinders, saws and lifts.
- Commercial autoBucket trucks, dump trucks and trailers.
What underwriters will ask
Having these ready means I can go to market on the first call. The quote form asks for the same things, and anything you don’t know yet can wait.
- Work: trimming, removal, stump grinding or land clearing, with rough percentages.
- Height: the highest you climb and whether you use a crane or bucket truck.
- Utility lines: whether you work near power lines.
- License: CSLB classification, if you have one, and ISA certification.
- Payroll and revenue: employees, subcontractors and gross receipts.
- History: current policies and loss runs.
California license rules for tree work
In California, the license classification for tree work changed on January 1, 2024. Here is where things stand, per the Contractors State License Board (CSLB):
- New licenses are C-49 Tree and Palm. CSLB no longer accepts applications for the C-61/D-49 Tree Service classification; any received after December 31, 2023 are processed as C-49 applications. Every C-49 applicant sits a trade exam, even if the license already carries other classifications.
- Existing D-49 holders can keep it. A D-49 issued before January 1, 2024 can still be used, and CSLB regards the scope of work as the same as C-49 (the C-49 wording adds palms).
- Workers' comp with no employees, through 2027. Business and Professions Code 7125 lets a licensee with no employees file an exemption instead of a policy, unless the license includes C-8, C-20, C-22, C-39 or D-49. C-49 is not on that list. If an active license includes D-49 and no workers' comp certificate is on file, CSLB removes the D-49 classification.
- Starting January 1, 2028. That version of 7125 is repealed on that date, and CSLB says all licensees, regardless of classification or whether they have employees, will need workers' comp. See what changes in 2028 and the no-employee question.
CSLB's exemption form also names only C-61/D-49, and CSLB treats the C-49 scope as the same work, so ask CSLB before filing a no-employee exemption on a C-49 license. From January 1, 2028, every license needs workers' comp either way. Once you hire anyone, the exemption no longer fits either way. Outside California, tree-work licensing and workers' comp rules vary by state.
Power lines: who may trim near them
Underwriters ask about utility lines because Cal/OSHA draws a hard line there. Under 8 CCR 3423:
- High voltage: no tree trimming within 10 feet of energized high-voltage lines unless it is line clearance work done under Article 38 of the High-Voltage Electrical Safety Orders.
- Line clearance work: only qualified line clearance tree trimmers, or trainees, as defined in section 2700, may do it, and sections 2940.2 and 2951 set the approach distances and requirements for that work.
- Low voltage (600 volts or less): a qualified tree worker trained in the listed electrical hazards may trim within 10 feet of the line but no closer than 1 foot.
If your crews do utility or line clearance work, say so up front and tell me who on the crew is qualified and how you document it. If you never work near lines, put that in writing on the application. Either way, the answer has to match what your crews actually do.
Chippers, bucket trucks and cranes
Equipment is split across policies, and gaps show up where they meet. Here is how IRMI describes the split:
- Mobile equipment: liability arising from mobile equipment is normally handled under general liability, while physical damage to the machine itself is usually insured on an equipment floater, a form of inland marine insurance. A vehicle subject to a compulsory or financial responsibility law is treated as an auto, not mobile equipment. See tools and equipment insurance.
- Bucket trucks: in IRMI's reading, driving belongs on commercial auto, while operating the boom falls under the general liability exception described above.
- Lifting others' property: the general liability form excludes personal property of others in your care, custody or control. IRMI describes riggers liability, an endorsement that modifies or deletes that exclusion, for contractors who move property and equipment owned by others, such as by crane.
Send me a list of every chipper, grinder, truck, trailer and crane with year, serial or VIN, and whether it's owned, rented or hired with an operator. That list decides which form each unit goes on.
Tree service insurance, answered
Why is tree service insurance hard to find?
Falling trees cause large property claims and tree work has high injury rates, so many standard carriers exclude it. Specialty markets write it, priced on height, crane use and the work you do.
Do I need a license for tree work in California?
Tree work on a job worth $1,000 or more in labor and materials generally needs a CSLB license; tree work has its own classification: C-49 Tree and Palm for licenses issued since January 1, 2024, and C-61/D-49 for older ones. I can help you line up the coverage a license requires.
Does general liability cover a tree falling on a house?
It's designed to: damage your work causes to someone else's property, like a limb dropped on a client's roof, is what general liability is for, subject to the policy's terms and exclusions. Damage to the tree you're working on and to your own equipment needs its own coverage.
Is crane work covered?
It has to be disclosed. Crane and bucket truck work is something underwriters ask about and rate for, so tell the carrier up front and read how your policy treats it.
Do C-49 tree contractors with no employees need workers' comp in California?
Until January 1, 2028, Business and Professions Code 7125 lists C-8, C-20, C-22, C-39 and D-49 as the classifications that can't file a no-employee exemption; C-49 isn't named, but CSLB considers its work the same as D-49, so check with CSLB before relying on an exemption. From January 1, 2028, all licensees need workers' comp regardless of classification or employees.
Do you offer tree service insurance outside California?
Yes. Clients across the country send the same quote form. Sam Alishahi is licensed in all 50 states and Washington, DC and places policies there directly. The shopping across carriers works the same way. Rules, minimums and markets differ by state — see insurance requirements by state.
