How to Spot an Unlicensed Tree Company
Key Takeaways
- Always verify CSLB contractor license status online before hiring any tree service company in California
- Request proof of liability insurance and workers' compensation coverage to protect yourself from financial liability
- Unlicensed companies often demand cash-only payments, lack written contracts, and cannot provide verifiable references
- Licensed tree companies carry proper insurance, provide detailed written estimates, and comply with all California regulations
- Hiring unlicensed contractors puts you at legal and financial risk if accidents, property damage, or injuries occur
Hiring an unlicensed tree company in California isn't just risky—it can leave you legally and financially liable. Under California Business and Professions Code §7028, any tree work over $500 (including labor and materials) requires a valid CSLB contractor's license. Here's how to protect yourself.
1. They Can't Provide a Valid CSLB License Number
This is the biggest red flag. Every legitimate tree service contractor in California must have a Contractors State License Board (CSLB) license. Ask for their license number upfront, then verify it yourself at cslb.ca.gov.
Our license: #900295 — verify it anytime.
2. They Offer a "Cash Discount" or Avoid Paperwork
Unlicensed operators often push for cash payments to avoid leaving a paper trail. Legitimate companies provide detailed written estimates, contracts, and receipts. If someone offers a steep discount for paying cash or refuses to provide documentation, walk away.
3. No Proof of Insurance
Licensed contractors carry general liability and workers' compensation insurance. If a worker gets injured on your property or your home is damaged, you could be held liable if the company isn't insured. Always ask for a certificate of insurance and verify it with the insurance provider.

4. They Show Up Unsolicited
Door-to-door tree service solicitors are often unlicensed. They may claim they "just finished a job nearby" and can offer you a deal. Reputable companies don't need to knock on doors—they have established reputations and steady client bases.
5. No Business Address or Online Presence
Legitimate tree service companies have a physical business address, a professional website, and verifiable online reviews. If you can't find them on Google, Yelp, or the Better Business Bureau, that's a major warning sign.
6. Extremely Low Bids
If a quote seems too good to be true, it probably is. Unlicensed operators undercut licensed companies because they skip insurance, proper equipment, safety training, and legal compliance. You'll pay more in the long run when the work is done poorly—or when you're held liable for an accident.
7. No Written Contract
California law requires contractors to provide a written contract for jobs over $500. If someone tries to start work with just a handshake or verbal agreement, they're likely unlicensed—and you have no legal recourse if something goes wrong.
What to Do If You've Hired an Unlicensed Contractor
If you've already hired an unlicensed tree company, you may have limited legal options. California law prohibits unlicensed contractors from suing to collect payment, but homeowners can sue them for poor workmanship. Report unlicensed activity to the CSLB at 1-800-321-CSLB (2752).
