C-49 License Insurance Requirements: Workers' Comp, Bonds, and LLC Rules

The core C-49 license insurance requirements are two items CSLB wants on file: a workers’ compensation certificate - with no exemption allowed, even if you work alone - and a $25,000 contractor bond. Depending on how your business is structured, the list grows: a second $25,000 bond if an RME qualifies your license, and a $100,000 worker bond plus $1 million in liability insurance if you are an LLC. Miss any item and the license does not issue. Let one lapse and the license suspends, automatically.

This guide walks through each requirement in the order you will hit it, plus the D-49 history that still confuses license lookups, and what enforcement actually looks like in 2026. California only - other states license tree work differently, where they license it at all.

What are the C-49 license insurance requirements?

Four items, depending on entity type. Every C-49 applicant and licensee needs proof of workers’ compensation insurance on file with CSLB - the tree classification cannot file the no-employee exemption, a rule carried over from SB 216 - and the $25,000 contractor bond, required since January 1, 2023 (raised from $15,000 by SB 607). A license qualified by a Responsible Managing Employee (RME) adds a second $25,000 Bond of Qualifying Individual, per CSLB’s bond requirements. Contractors licensed as LLCs add two more items under CSLB’s LLC rules: a $100,000 employee/worker bond under B&P section 7071.6.5 and liability insurance of at least $1 million under B&P section 7071.19. CSLB does not otherwise require general liability insurance for sole proprietors, partnerships, or corporations, though clients routinely demand it by contract. Each requirement is covered below in the order you will hit it.

First, the classification: what happened to the D-49 tree service license?

CSLB created the C-49 Tree and Palm Contractor classification on January 1, 2024, replacing C-61/D-49; existing D-49 licenses were converted automatically. Same license numbers, no fee, per CSLB’s 2023 industry bulletin on the change. CSLB estimated the conversions would take about 18 months, so by now they are expected to be complete - though you will still find CSLB’s own workers’ comp page referring to “C-61/D-49 Tree Service.” The agency’s paperwork lags its own reorganization. Yours might too; if your insurance documents still reference D-49, it has not caused problems for our clients, but it is worth cleaning up at renewal.

The official C-49 scope, per CSLB’s classification description: a tree and palm contractor “plants, maintains, and removes trees and palms,” including pruning, stump grinding, and tree, palm, or limb guying. Incidental pruning by nurserypersons and gardeners is carved out separately under B&P section 7026.1.

New applicants take two exams: the Law and Business exam and the C-49 trade exam, for which CSLB publishes a study guide. The exams are the easy part to plan for. The insurance filings are where applications stall, so let’s take those one at a time.

Requirement 1: do C-49 contractors need workers’ comp without employees?

Yes, without exception. Since January 1, 2023, California tree service contractors (C-61/D-49, now C-49) must carry workers’ compensation insurance even with no employees, under SB 216 (2021). CSLB does not accept workers’ comp exemptions from C-8, C-20, C-22, C-39, and C-61/D-49 (now C-49) license holders. The exemption form exists - other classifications still use it - but for the tree classification it is simply unavailable. A license qualified by an RME cannot file the exemption either, per CSLB’s workers’ compensation requirements page.

What CSLB needs on file is a certificate of insurance from your carrier (or a valid Certification of Self-Insurance). In practice the carrier handles the filing: State Fund, for instance, says it automatically sends proof of coverage to CSLB when a contractor policy is bound. Your job is to make sure the policy exists before the application or renewal goes in, and that it never lapses afterward.

If you are a true solo operation, what you bind is a minimum-premium policy with the owner excluded - what brokers casually call a ghost policy. The mechanics, entity-by-entity exclusion rules, and what those policies do and do not cover are in Workers’ Comp With No Employees. If you run crews, see our main workers’ comp page.

One rule that bites growing companies: if a contractor with an exemption on file hires anyone subject to California workers’ comp law, the exemption becomes invalid and proof of coverage must reach CSLB headquarters within 90 days of the hire, per CSLB. For C-49 holders this mostly matters in mixed-classification licenses, since the tree classification never had an exemption to begin with - but if you hold C-49 alongside another class, do not assume an old exemption still protects anything.

Requirement 2: how much is the C-49 contractor bond?

Every active license needs the contractor bond on file: $25,000, required since January 1, 2023 (raised from $15,000 by SB 607). It had sat at $15,000 since 2016, so plenty of older guidance still quotes the wrong number.

A point worth being blunt about: the bond protects consumers and employees, not you. If the surety pays a claim - say, for a contract violation or unpaid wages - it has the right to recover from you personally. Sureties typically price the bond against your credit, and it is one of the cheaper items on this list, but treat it as a guarantee you are signing, not coverage you are buying.

Requirement 3: who needs the Bond of Qualifying Individual?

If your license is qualified by a Responsible Managing Employee, CSLB requires a separate $25,000 Bond of Qualifying Individual in addition to the contractor bond, per CSLB’s bond requirements page. The same applies to certain Responsible Managing Officer arrangements tied to ownership percentage thresholds - the exact cutoffs are on CSLB’s bond page and worth checking against your actual ownership structure before you file, because this is the requirement applicants most often discover late.

If you qualify your own license as an owner, this one usually does not apply to you. It shows up when companies borrow a qualifier - which, as a side note, also locks the license out of the workers’ comp exemption under the RME rule above. The two requirements travel together.

Requirement 4: what extra insurance and bonds do LLC licensees need?

Contractors licensed as LLCs carry two obligations the other entity types do not, per CSLB’s LLC licensing page:

• A $100,000 employee/worker bond under B&P section 7071.6.5, on top of the $25,000 contractor bond. It protects employees damaged by unpaid wages or benefits.
• Liability insurance of at least $1 million under B&P section 7071.19, for licensees with five or fewer personnel of record, plus $100,000 per additional person, capped at $5 million. Policies must be written by California-admitted insurers or eligible surplus lines insurers.

This is the one place California law mandates general liability for a tree contractor. Sole proprietors and corporations face no statutory GL requirement - clients impose it by contract instead, which we cover in the pillar guide and on our general liability page. If you are choosing an entity right now, price the LLC’s extra bond and mandated liability policy into the decision. Plenty of one-crew operations form an LLC for liability protection without realizing they just signed up for a statutory insurance minimum.

What happens if a C-49 insurance requirement lapses?

The license suspends, automatically. CSLB’s language leaves no room for interpretation: “Failure to maintain workers’ compensation insurance coverage will result in the license being suspended. Any work performed while the license is suspended is considered to be unlicensed and disciplinary action can be taken against you.” The suspension lifts once acceptable proof is received and processed - which is not instant, and jobs do not wait.

Unlicensed work is not a paperwork problem. Under B&P section 7028, a first offense is a misdemeanor carrying up to six months in county jail and/or a fine up to $5,000, and a second conviction brings a mandatory minimum of 90 days in jail plus a fine of the greater of $5,000 or 20% of the contract price. A suspended license puts every job you finish in that territory.

The enforcement climate is also tightening. SB 291 (2025) created significant civil penalties for licensees who falsely claim the workers’ comp exemption and requires CSLB to establish a verification process, reporting to the Legislature by January 1, 2027, per the California Legislature and the USD Consumer Protection Policy Center. At its March 2026 board meeting, CSLB went further, proposing a dedicated workers’ comp enforcement unit and audits of roughly 5% of exemption filings annually - proposals at this stage, not law, per the USD Consumer Protection Policy Center. None of that touches a C-49 holder directly, since you cannot file the exemption anyway. But it signals where CSLB is spending attention, and a tree contractor with a coverage gap is an easy find.

Our honest advice: the simplest compliance strategy is boring continuity. Same-day binding is sometimes possible, but reinstating a suspended license mid-project costs more than any premium difference you were chasing. Calendar the renewal, keep the comp policy unbroken, and let the bond auto-renew.

Do you need a license to remove a tree in California? The $1,000 line

For almost all paid tree work, yes. A CSLB license is required for tree work jobs of $1,000 or more in combined labor and materials (threshold raised from $500 to $1,000 by AB 2622, effective January 1, 2025). The under-$1,000 exemption in B&P section 7048 also demands that the work be casual and minor, require no permit, and involve no hired help - and unlicensed advertising is allowed only for sub-$1,000 jobs and must disclose the lack of a license.

Run those conditions against real tree work and the exemption nearly vanishes. A removal with a groundman fails the no-help test. A street tree fails the no-permit test in most cities. Anything involving a crane or a full day fails the price test. If you are doing tree work for money in California, plan on the C-49.

FAQ

Can a C-49 contractor file a workers’ comp exemption?

No. CSLB does not accept workers’ comp exemptions from C-8, C-20, C-22, C-39, and C-61/D-49 (now C-49) license holders. Since January 1, 2023, tree service contractors must carry workers’ compensation even with no employees, under SB 216. Owner-only operations typically use a minimum-premium policy with the owner excluded.

How much is the C-49 license bond?

$25,000 - the standard CSLB contractor bond, required since January 1, 2023 (raised from $15,000 by SB 607). Licenses qualified by an RME also need a separate $25,000 Bond of Qualifying Individual, and LLC licensees file an additional $100,000 worker bond, per CSLB.

What happened to the D-49 tree service license?

CSLB created the C-49 Tree and Palm Contractor classification on January 1, 2024, replacing C-61/D-49; existing D-49 licenses were converted automatically, keeping their license numbers at no cost, per CSLB’s industry bulletin. New D-49 applications stopped at the same time.

What exams does the C-49 require?

New applicants pass two exams: the CSLB Law and Business exam and the C-49 trade exam. CSLB publishes a C-49 study guide outlining the trade exam content.

Do I need a C-49 license to remove a tree in California?

If the job is $1,000 or more in combined labor and materials, yes, per B&P section 7048 as amended by AB 2622. Below $1,000, the work must also be minor, permit-free, and done without helpers to qualify for the exemption - conditions real tree removals rarely meet.

What is the penalty for unlicensed tree work in California?

Under B&P section 7028, a first offense is a misdemeanor punishable by up to six months in county jail and/or a fine up to $5,000; a second conviction carries a mandatory minimum 90 days in jail plus a fine of the greater of $5,000 or 20% of the contract price. Work performed on a suspended license counts as unlicensed.

Next step

If you are applying for a C-49, get the workers’ comp policy and bond moving before you schedule exams - the filings, not the tests, set the timeline. If you already hold the license and want the insurance stack checked against what CSLB and your contracts actually require, we review programs starting 75 days before renewal. Start at our tree care overview or contact us directly. Pulling your loss runs first speeds everything up.
