Licensed & Insured Tree Service: What to Actually Check

The license: CSLB C-49 "Tree and Palm Contractor"

Every Redding tree company we reviewed for our company comparison describes itself as "licensed and insured" — that phrase is the industry standard self-description, and it's genuinely accurate for most of them. But it's also a claim you can verify in under a minute, and most competitor sites in this niche don't explain what the phrase actually means or make it easy to check. In California, the relevant license is the Contractors State License Board's C-49 "Tree and Palm Contractor" classification, which replaced the older D-49 "Tree Service" specialty classification effective January 1, 2024.

A C-49 license is required for most paid tree removal, trimming, and stump-grinding work. The one exception is California's statewide minor-work exemption (Assembly Bill 2622): an unlicensed person can perform a job worth $1,000 or less in total labor and materials, provided the work needs no permit and the person isn't employing anyone else on the project. All three conditions have to hold — if any one fails, a licensed C-49 contractor is required no matter the dollar amount. In practice, most tree removal and any significant trimming job exceeds $1,000 anyway, so the exemption mostly matters for very small jobs — trimming a single small ornamental, say.

How to check a license number yourself

1. Get the license number. Ask the company directly for its CSLB license number, or look for it printed on their website, quote, or invoice.

2. Go to CSLB's Check a License tool. Visit cslb.ca.gov and use the free public "Check a License" search.

3. Confirm the classification is C-49. The record lists every classification the license covers. Confirm C-49 ("Tree and Palm Contractor") appears — a license in a different trade classification doesn't authorize tree work.

4. Check the status and expiration date. The license should show as "Active" (not expired, suspended, or revoked) with a current expiration date.

5. Check the bond and workers' compensation. The record shows whether a contractor's bond and workers' compensation insurance are currently on file — both matter if something goes wrong on your property.

6. Check for complaints or legal actions. CSLB's record also shows any disciplinary actions or legal history tied to the license. A clean record isn't a guarantee, but a history of complaints is worth asking the company about directly.

Beyond the license: insurance and the crew doing the work

A CSLB license record shows whether a bond and workers' compensation insurance are on file, which is a good first check — but for a job of any size, ask directly for a current certificate of insurance showing both general liability and workers' compensation coverage. General liability protects your property if something goes wrong — a limb through a fence, a dropped section on the driveway. Workers' compensation protects you: if an uninsured worker is injured on your property, the claim can end up against your homeowner's policy instead of theirs.

It's also worth asking directly whether the crew showing up on the day is the company's own employees or a subcontractor — and if it's a sub, whether that company is separately licensed and insured. This isn't a red flag by itself (subcontracting is common and legal), but you want the same insurance questions answered for whoever is actually doing the climbing.

A separate thing: City of Redding business license

This is unrelated to CSLB and easy to confuse. Any business that conducts work in the City of Redding, or is based there, also needs a City of Redding business license — including CSLB-licensed contractors, whether or not the work itself happens inside city limits. This is a local administrative requirement, not a trade-competency license, and it isn't something a homeowner typically needs to verify before hiring — but it explains why a company's paperwork might reference both a CSLB number and a City business license number. Anderson and Shasta Lake are separate cities with their own business-license systems; unincorporated Shasta County requires neither city's license. See our service area page for the jurisdiction breakdown.

Red flags worth naming directly

• No license number offered, or a number that doesn't check out on CSLB's site.

• Demanding full payment up front, before any work has started.

• No written estimate — a verbal number only, with nothing itemized.

• Pressure to decide immediately, especially after a storm when demand spikes and less scrupulous operators sometimes appear from out of the area.

• Reluctance to name insurance carriers or provide a certificate of insurance on request.
