Insurance for Tree Service Businesses
A tree crew works at height, near power lines, with saws and a chipper running, and California’s first question for the business is which license it holds. We look for tree service insurance that fits C-49 Tree and Palm work and the claims a falling limb can cause, and the insurer decides once it has reviewed your crew, equipment and the heights you work at.
Tree service insurance starts with the C-49 license
Since January 1, 2024, the Contractors State License Board no longer accepts applications for the old C-61/D-49 Tree Service limited specialty. New tree businesses apply for the C-49 Tree and Palm Contractor classification, and every C-49 applicant must pass a trade exam, whatever other licenses they hold. Contractors who received a D-49 before that date may keep working under it; CSLB treats the work as the same, with palms added to the C-49 description.
Small jobs have a narrow exemption. Since January 1, 2025, work under $1,000 in total needs no license, but only when it needs no permit and you employ nobody on the job, and an unlicensed operator’s ads must say so. Every licensee carries the $25,000 contractor’s bond, shared across all jobs rather than per job, and an LLC licensee also needs a $100,000 bond. Our contractor and surety bonds page covers both.
Workers’ comp when you climb alone
Business and Professions Code 7125(b) removes the no-employee exemption for holders of a handful of classifications, D-49 among them, for licenses active after July 1, 2023. A D-49 owner who climbs alone still needs a workers’ compensation policy on file. CSLB’s page on the rule names the D-49 but not the newer C-49, so C-49 holders should confirm their own position with CSLB. A broader rule requiring every contractor to carry comp was set by SB 216 for January 1, 2026, and CSLB’s November 2024 materials say SB 1455 moved it to January 1, 2028; check CSLB for the current date.
The rule reflects the work. The Bureau of Labor Statistics counted 80 fatal work injuries among U.S. tree trimmers and pruners in 2023, second in their sector only to landscaping and groundskeeping workers at 102. Falls, struck-by injuries from a cut limb and electrical contact are the injuries behind this trade’s comp costs.
Class 0106: why one ladder changes the rate
The WCIRB rates tree pruning, repairing or trimming under class 0106 whenever any part of the work at a job needs elevation by ladder, lift or climbing, and the ground crew on that job goes with it. Pruning with no elevation stays in landscape gardening, explained on our class code 0042 page. As of November 2026, the WCIRB class page showed an advisory pure premium rate of $12.393 per $100 of payroll for 0106 effective September 1, 2026, more than double the landscape gardening rate. Advisory rates are a benchmark, and insurers usually charge more once their expenses are added.
Keep job records showing which jobs needed a ladder, lift or climb, since that is the test the classification uses.
Cal/OSHA tree work rules and the line-clearance limit
Article 12 of California’s General Industry Safety Orders, sections 3420 to 3428 of Title 8, governs tree work. Section 3421 requires an Injury and Illness Prevention Program, a qualified tree worker in charge at each work location, documented training that includes electrical hazards and PPE, a job briefing before each assignment, daily equipment inspection, rescue procedures and first aid and CPR training, with at least two trained people present on field jobs with two or more employees.
Section 3423 tells crews to treat every line as energized. Nobody trims within 10 feet of an energized high-voltage line except qualified line-clearance tree trimmers or trainees, a qualified tree worker may work within 10 feet but no closer than 1 foot of a line of 600 volts or less, and metal-core climbing rope stays away from energized conductors. Tell the underwriter whether your crews do any line-clearance work, and keep the written program these sections require ready to share.
Tree service liability insurance for limbs, roofs and the wrong tree
The claims behind a tree service policy are easy to picture: a dropped branch that damages power lines or injures someone, a falling limb that hits a pedestrian, a stump-grinding accident and the wrong tree removed. General liability is the policy for injury to the public and damage to property such as a client’s roof, fence or car. Some liability policies exclude tree service work, so read the form for tree-removal, height and crane exclusions before relying on it.
Removing the wrong tree or giving advice that harms one is a question about your judgment, which is where professional liability fits for arborist consulting. Crews that spray for pests or apply herbicide should ask about contractors pollution liability, since runoff and misapplication bring claims of their own.
Chippers, stump grinders and bucket trucks
Bucket trucks, chip trucks and trailers belong on commercial auto, with hired and non-owned auto for rented trucks and crew members who drive their own pickups to a job. Saws, climbing gear, chippers, stump grinders and lifts go under tools and equipment insurance; items worth more than $2,500 may need to be listed one by one.
An off-season storage fire that destroys the equipment is a loss of your own property, so it sits with the equipment policy, not liability.
HOA, city and property manager contracts
Clients often want a certificate of insurance or a bond before they sign, and proof of workers’ comp is often needed to sign a contract at all. Some also ask to be added to your policy; our guide to additional insured endorsements explains how that works. When a contract sets limits above your liability policy, a commercial umbrella adds a layer over it.
What tree service insurance costs
Insureon’s tree service cost page, updated September 30, 2026, publishes national figures from its own small-business customers; they are not California prices or a Mithril1 quote. General liability runs about $156 a month ($1,875 a year) at $1 million per occurrence and $2 million aggregate with a $500 deductible, workers’ comp about $215 a month ($2,580), commercial auto about $299 a month ($3,590) and tools and equipment about $53 a month ($637). These fit solo and very small crews at standard limits; established tree companies pay well above them.
Comp is rated on payroll by class code, liability on revenue and the type of work, and auto on each truck and driver. Using Insureon’s figures, a one-truck operator with general liability and workers’ comp would start near $4,455 a year, and adding commercial auto and equipment cover brings the total to about $8,682.
Removals over structures, crane work, line-clearance jobs, a large elevated payroll in 0106, older bucket trucks and past injury claims raise the premium. Ground-level pruning, a documented Article 12 safety program, experienced drivers and a higher deductible lower it. The underwriter sets the figure from what your application shows.
A few useful answers
Common questions
Is the tree service license a C-49 or a D-49 now?
New applicants have applied for the C-49 Tree and Palm classification, which has a trade exam, since January 1, 2024. A D-49 issued before then still lets you work, and CSLB treats the work as the same.
Do I need workers’ comp for my tree service if I work alone?
D-49 holders do: B&P 7125(b) removes the no-employee exemption for D-49 licenses active after July 1, 2023. CSLB’s page on that rule doesn’t name the C-49, so C-49 holders should confirm their status with CSLB.
Why is workers’ comp the biggest part of tree service insurance?
Elevated tree work is rated in class 0106, which the WCIRB class page showed at an advisory $12.393 per $100 of payroll effective September 1, 2026, more than double landscape gardening. One job needing a ladder or lift puts that job’s whole crew in 0106.
Can my crew trim near power lines?
Not within 10 feet of an energized high-voltage line unless they are qualified line-clearance tree trimmers or trainees (Cal/OSHA section 3423). Tell your insurer about any line work you take on.
Can a tree service with a bucket truck get coverage through Mithril1?
That is possible when an insurer approves the application after reviewing your trucks, drivers, license and the heights you work at. We request liability, auto, equipment and comp quotes together so each one lists the same vehicles and crew.
