Tree Service Workers' Comp Insurance (Code 0106)
Updated: 3 days ago
Quick answer: Tree service workers' compensation is written under class code 0106 — "Tree Pruning, Spraying, Repairing—All Operations & Drivers" under NCCI, and "Tree Pruning, Repairing or Trimming" under California's WCIRB. It is one of the highest-rated, hardest-to-place workers' comp classes in the country because the work stacks chainsaws, heights, struck-by exposure, and electrocution near power lines into a single job with a fatality rate reported at roughly 30 times the all-industry average. Most standard carriers decline 0106 outright. CPR Business Solutions places tree service accounts — including high-mod, previously-cancelled, and hard-to-place risks — nationwide, with a California focus.
Retail agents know the pattern: run a tree service prospect through your standard markets and you get four declines before lunch. Owners have lived the other side — the carrier that dropped you after one claim, the renewal that doubled, the broker who stopped calling back. Below is how the class works, why it scares underwriters, and how we place the accounts other agents can't.
Why tree service workers' comp is so hard to place
Tree care is one of the most dangerous jobs in America. The NIP Group cites a fatality rate around 110 per 100,000 workers — roughly 30 times the all-industry average, the same severity tier as roofers and steel erectors. Underwriters price on the tail here, and the tail on a tree service claim is a fatality or a permanent disability.
Here's what an underwriter sees when a 0106 submission crosses the desk:
Chainsaws in motion, often overhead — lacerations and amputations, run by a fatigued worker on an unstable surface.
Work at height — falls from trees and aerial lifts are a leading cause of tree care fatalities, and every foot of elevation raises severity.
Struck-by exposure — falling limbs, cut sections, and rigging failures put ground crews in the drop zone.
Electrocution near power lines — tree work shares airspace with energized conductors; OSHA enforces minimum approach distances because contact events are frequently fatal.
Chippers and stump grinders — feed-mechanism injuries are catastrophic and hard to survive.
Layer on the workforce reality: high turnover, seasonal and inexperienced labor, and payroll that swings hard with storm season. Foresight Risk notes that roughly half of serious tree care injuries hit workers 34 and younger, and that the share of *serious* injuries has been climbing. Translation for an underwriter — fewer claims, but the ones that land are worse.
That's why standard carriers "summarily decline" the class, in NIP's words — it isn't personal to the account. Most admitted markets don't have the appetite or the reinsurance treaty to hold 0106 severity, so the risk lands in the excess and surplus market and with a short list of specialty programs. It's the same dynamic we cover in our guide on which carriers actually have appetite for hard accounts — a market-appetite problem, not a pricing problem you can negotiate your way out of.
What class code is used for tree service workers' comp?
Class code 0106 — the governing class
The workhorse code is 0106. Under NCCI, the full phraseology is "Tree Pruning, Spraying, Repairing—All Operations & Drivers." It covers specialist contractors who use hand tools or mechanical equipment to prune, spray, repair, trim, or fumigate trees — including ladders, aerial buckets, and drivers.
In practice, 0106 sweeps in the whole tree operation when elevation is involved: tree removal requiring above-ground work, stump grinding tied to that removal, cabling and tree surgery, aerial and bucket-truck work, and the chipping, cleanup, and hauling of debris connected to the job. It's an "all operations" class — you don't carve the dangerous parts out and rate them separately.
How does California classify tree service (WCIRB 0106)?
California is an independent, non-NCCI state, so it runs its own classification system through the WCIRB. California also uses 0106, described as "Tree Pruning, Repairing or Trimming." The line that matters most in California — and the one that gets accounts in trouble at audit — is the elevation test:
0106 applies when any portion of the operations requires elevation, including but not limited to using ladders, lifts, or by climbing.
If no operation at a given job or location requires elevation, that work may fall under 0042 (Landscape Gardening) instead. But the moment a crew goes up, the tree work belongs in 0106.
What's the difference between 0106 and 0042?
This is the most common classification mistake in the tree space. 0042 (landscape gardening) is ground-level work — lawn maintenance, mowing, planting, weed abatement, fertilizing, ground-based trimming with pole saws, and ground-level chipping. It rates far lower than 0106 because the exposure is far lower.
The temptation is obvious: write the crew under the cheaper landscaping code and pocket the difference. Don't. In California the elevation test governs, and auditors check it. Misclassifying elevated tree work as landscaping doesn't save money — it defers a bill: at audit the carrier reclassifies the payroll to 0106 and issues a large additional premium, and in a bad case rescinds the policy for material misrepresentation. Documenting which crews work at elevation and which don't is what keeps a mixed operation clean.
Related and companion codes
You may also see landscaping (0042 in CA) and, in some independent-bureau states, different numbers entirely — Delaware and Pennsylvania use 0005/0013/0609 rather than 0106. But for the field crew doing elevated tree work, 0106 is the governing class virtually everywhere, and it's the number that drives the premium.
How is tree service workers' comp rated?
The mechanics are the same as any WC class, but the inputs run hot:
(Class code rate ÷ 100) × payroll × experience modification factor = premium (before schedule and other credits/debits).
Three things determine what a tree service account actually pays:
The filed 0106 rate for the state. This varies enormously — from single digits per $100 of payroll in lower-rated states to well past $30 per $100 in the highest. Don't quote these as gospel; filed rates and loss-cost multipliers change by carrier.
Payroll, correctly classified. Every dollar of elevated-crew payroll that lands in 0106 is priced at the 0106 rate. Getting the class split right — and defensible at audit — is half the battle.
The experience modification factor (X-mod). The multiplier that rewards or punishes an account's own loss history. In a class this severe, one serious claim can drive a mod well above 1.00 and hold it there for three years. A high mod is the most common reason a tree service account gets pushed out of the standard market — the problem we break down in our high X-mod placement guide.
A worked dollar example (illustrative only)
These numbers are illustrative — do not treat them as filed rates. Verify the current rate for your state and account.
Say a tree service has $500,000 in elevated-crew payroll and, for illustration, a 0106 rate of $15.00 per $100:
Base manual premium = ($15.00 ÷ 100) × $500,000 = $75,000
Now apply the experience mod to that same $500,000 payroll:
At a 0.90 mod (better-than-average losses): $75,000 × 0.90 = $67,500
At a 1.35 mod (a few claims in the window): $75,000 × 1.35 = $101,250
A roughly $34,000 swing on identical payroll, driven entirely by loss history — which is why we spend as much time on the loss narrative as on the application. The $15.00 rate is a stand-in for the math, not a quote.
What do underwriters look at on a tree service submission?
When we take a 0106 account to market, the underwriter is answering one question: *is this a disciplined operation or a claim waiting to happen?* What moves the needle:
Experience mod and loss runs — three to five years, currently valued. One large claim with a clear cause and a fixed process reads very differently from chronic frequency.
Nature of the work — residential trimming differs sharply from utility line clearance or large-scale removal; height and proximity to energized lines drive the price.
Crew experience and turnover — tenured climbers and a stable crew lower perceived frequency; high churn raises it.
Safety and training program — documented chainsaw training, aerial rescue, fall protection, job-site hazard assessments. ANSI Z133 compliance is a strong signal.
Equipment and maintenance — age and upkeep of bucket trucks, chippers, and rigging.
Subcontractor certificates — uninsured subs become your insured's payroll at audit, so underwriters want a real process.
Return-to-work program — controlling claim development matters as much as preventing claims.
Accounts that place cleanly are the ones where this picture is complete — the ones that struggle usually have a thin submission, not a bad risk.
How CPR places tree service accounts other agents can't
We're a workers' comp MGA and wholesaler built for the classes standard carriers run from — high-hazard, high-mod, hard-to-place. Tree service sits in the center of that. What we do differently:
We work markets that stay in the class. Standard carriers cycle in and out of 0106 by loss year. We maintain relationships with carriers and programs that underwrite tree service deliberately, so we're not starting from zero every renewal.
We package the account, not just submit it. A high-mod risk emailed as a bare ACORD gets declined. The same risk — presented with a loss narrative, a documented safety program, and a clean payroll split — gets a quote. We build the submission that gets a "yes."
We handle the accounts nobody else wants. Mid-term cancellations, non-renewals, lapses, prior claims, new ventures with no history — these are our normal, not our exceptions. If you've read our take on roofing workers' comp, the playbook is the same: hard class, deliberate markets, a submission built to survive underwriting.
We know California cold. Because so much high-mod tree work is in California, we live in the WCIRB rules — the 0106/0042 elevation test, dual-classification documentation, and the audit exposure of getting the split wrong.
Levers that lower your tree service workers' comp premium
You can't change that 0106 is a high-rated class. You *can* change what you pay within it:
Get the class split right. Ground-only crews and clerical staff don't belong in 0106. Document elevation so you're not overpaying — or underpaying and eating an audit bill.
Attack the X-mod. The biggest controllable input. Fewer and less-severe claims today lower the multiplier for three years, and a real return-to-work program keeps claims from developing into mod-inflating reserves.
Build a documented safety program. ANSI Z133, chainsaw and aerial training, fall protection, and daily hazard assessments aren't just safety — they're underwriting credits, often the difference between a decline and a quote.
Manage subcontractors. Collect certificates from every sub, every time; uninsured subs get added to your payroll at audit at the 0106 rate.
Report and manage claims fast. Early reporting and active claim management control severity, which controls your mod.
These are the levers underwriters actually credit, and they compound over the mod window.
Coverage we arrange
Tree service owners rarely need workers' comp in isolation. Through our carrier and wholesale relationships, we help arrange the full program:
Workers' compensation (class code 0106 and companion codes) — our specialty
General liability for property damage and third-party bodily injury
Commercial auto for bucket trucks, chip trucks, and crew vehicles
Inland marine / equipment coverage for chippers, stump grinders, and rigging
Excess/umbrella liability over the primary limits
Availability depends on the account and the market — tell us what the operation needs and we'll tell you what we can build.

Frequently asked questions
What class code is tree service workers' comp?
Almost always code 0106. NCCI phrases it "Tree Pruning, Spraying, Repairing—All Operations & Drivers"; California's WCIRB uses 0106 for "Tree Pruning, Repairing or Trimming." It applies whenever any part of the job requires elevation — ladders, lifts, or climbing — including the removal, chipping, and cleanup tied to that work.
Why is tree service workers' comp so expensive?
Because 0106 stacks four severe hazards into one job: chainsaws, work at height, struck-by from falling limbs, and electrocution near power lines. Tree care carries a fatality rate reported at roughly 30 times the all-industry average. That severity, plus high turnover and inexperienced crews, makes it one of the highest-rated WC classes.
Can I write my tree crew under landscaping code 0042 to save money?
No — and it costs you at audit. In California, 0042 (landscape gardening) applies only when no operation at a job requires elevation. The moment a worker climbs or goes up a ladder or lift, the crew belongs in 0106. Misclassifying triggers a large additional premium and can void the policy.
Can you place tree service workers' comp with a high X-mod?
Yes. A high experience mod is exactly what pushes 0106 accounts out of the standard market and into ours. We place them by pairing the account with carriers that underwrite the class deliberately, and by presenting the loss history with context — what happened, what changed, and what the crew does differently now.
Do you write tree service accounts that were just cancelled or non-renewed?
Regularly — a mid-term cancellation or non-renewal is one of the most common reasons a submission reaches us. Send the loss runs, the reason for cancellation, and a clear picture of current operations. We work markets that stay in the class through hard cycles, so crews stay covered without a lapse.
How much does tree service workers' comp cost?
Rates are quoted per $100 of payroll and vary widely by state, payroll, and experience mod. Published 0106 figures run from single digits in some states to well over $30 per $100 in the highest-rated ones. Treat any number you see online as illustrative and verify the current filed rate for your state.
Do you place tree service accounts in California?
Yes — California is a core focus. It's a non-NCCI state, so WCIRB governs 0106 classification and rating, and the 0106/0042 elevation test is enforced closely at audit. We know the California tree service market, the carriers that write it, and how to document elevation and payroll split to survive audit clean.
What do you need to quote a tree service account?
An ACORD 130 application, 3–5 years of currently valued loss runs, the current experience mod worksheet, a payroll breakdown by class code, and a short description of operations — crew size, equipment, height of work, and proximity to power lines. Safety documentation helps. Email proposals@cprbrokers.com or call 714-928-3858.
