Contractor Verification System: Checking Licenses, Bonds, and Complaints

Why a Clean CSLB Lookup Isn't Enough in a Fire Rebuild Zone

The stakes for hiring a contractor in Altadena right now go far beyond getting bad workmanship. Unlicensed contracting on structures damaged in a Governor-proclaimed disaster is a felony in California, carrying up to 3 years imprisonment and fines of $10,000, and the LA County District Attorney's Office is actively partnering with CSLB to prosecute cases in the Eaton Canyon fire zone, including felony charges announced against five unlicensed contractors in December.

That enforcement climate makes one thing clear: verification matters more here than almost anywhere else in California. Yet the most common verification step — running a license number through the CSLB lookup — tells you less than most homeowners assume. As one contractor verification guide puts it, "A contractor license number does not mean much on its own. Anyone can print a number on a business card or a truck door."

The deeper problem is that the public record itself has gaps. Between 2020 and 2024, CSLB closed at least 10,719 complaints without investigation — and those complaints never appeared on the contractors' public license pages. The Anchored Tiny Homes collapse illustrates the pattern: more than 450 homeowners lost deposits totaling $12.8 million, and although CSLB received 55 complaints, only 10 were made public.

So a clean CSLB record is not proof of a clean contractor. It is one data point in a fuller routine that should also include:

• Requesting a Certificate of Insurance and calling the insurer directly using the number on the certificate — a policy can lapse for non-payment days after a certificate is issued.
• Calling references from projects completed within the last 24 months, asking whether final cost matched the contract and whether permits and inspections cleared.
• Cross-referencing BBB, Google, and Yelp for complaint patterns rather than star ratings.
• Checking litigation history, since CSLB can suspend the license of any contractor who fails to satisfy final judgments related to construction.
• Confirming the $25,000 contractor bond, which remains an often-overlooked recovery path independent of any CSLB action.

It also helps to understand what CSLB can and cannot do. According to CSLB's own guidance, its investigations are not intended to obtain restitution and do not guarantee recovery — homeowners seeking their money back are directed to the courts. The complaint process creates a record and regulatory pressure; the bond claim, small claims action, or lawsuit is what actually recovers money.

For homeowners weighing Eaton Fire rebuild decisions in Altadena, we recommend treating the license lookup as the starting point, not the finish line — and verifying insurance, references, and complaint history before any contract is signed. When you are ready to discuss a rebuild, a free build consultation through Altadena Custom Home Builder is a good place to start; any builder you consider, including our featured JMB Builders LLC (CSLB #1103479), should be able to pass every step of that routine on the record.

Licensed, Bonded, Insured: Three Different Things You Must Check Separately

Hearing "we're licensed, bonded, and insured" means nothing until you verify each claim independently — because these are three separate credentials, and a contractor can hold one or two while missing the third. A trustworthy contractor on a significant project is usually all three, and each one protects you differently.

Licensed means the contractor met California's state requirements. Run the number through the CSLB's Check a License tool to confirm status, classification, bond, and workers' comp disclosure. Remember that anyone can print a license number on a business card or truck door — the lookup, not the card, is what counts.

Bonded refers to the $25,000 surety bond every California contractor must maintain and file with the CSLB. This is the recovery path homeowners most often overlook. Because CSLB is a regulator, not a collection agency, it cannot order restitution — but a bond claim works independently of any CSLB action, giving you a financial remedy if the contractor abandons the job or breaches the contract.

Insured is where the biggest verification gap lives. Ask for a Certificate of Insurance naming you as certificate holder, then call the insurer directly using the number printed on the certificate — not a number the contractor hands you. A fraudulent or lapsed certificate looks identical to a valid one until you make that call, and policies can lapse for non-payment days after a certificate is issued. That five-minute phone call is the single highest-leverage step in the entire hiring process, and it's the one most homeowners skip.

• Request a Certificate of Insurance before signing anything — it's a free, standard document, and hesitation to produce one is a red flag.
• Verify at least $1,000,000 in general liability coverage; for high-value rebuilds, $2,000,000 is the smarter floor.
• Confirm active workers' compensation — if a worker is injured on your property without coverage, you may be exposed to liability.

That workers' comp point deserves emphasis for Altadena rebuild homeowners managing large crews on Eaton Fire lots. California has raised the stakes for contractors who falsify comp exemptions: under SB 291, minimum fines reach $10,000 for sole owners and $20,000 for others starting in 2026 — but penalties don't shield you from an injury claim on your own lot.

At Altadena Custom Home Builder, we tell every homeowner we work with — including those evaluating builders like JMB Builders LLC (CSLB #1103479) — to run this three-part check on any candidate, regardless of reputation or referral. A referral is a great start, not a substitute for verification.

The Five-Step Verification Routine for Your Altadena Build

A clean license number on a truck door proves nothing — anyone can print one. For an Altadena build, especially an Eaton Fire rebuild where the LA County DA is actively prosecuting unlicensed contractors, verification is a five-step routine, not a single lookup.

Step 1: Run the CSLB lookup. The CSLB Check a License tool confirms status, classification, bond, workers' comp, and complaint disclosure. Confirm the classification actually covers your scope — a B-1 general building contractor for a ground-up home, not a specialty trade stretched beyond its license.

Step 2: Request a Certificate of Insurance naming you as certificate holder. A COI is a free, standard document; a contractor who cannot produce one is uninsured or underinsured. For a high-value hillside or rebuild project, industry guidance recommends at least $1,000,000 in general liability — $2,000,000 for larger renovations.

Step 3: Call the insurer directly, using the number printed on the certificate, not one the contractor provides. As one verification guide puts it, a fraudulent or lapsed certificate looks identical to a valid one until you make that call — policies can lapse for non-payment days after the certificate is issued. It takes five minutes and is the highest-leverage step in the process.

Step 4: Call references from projects completed within the last 24 months, and ask structured questions:

• Did the project finish on time, and if not, why?
• Did the final cost match the contract price?
• Were permits pulled by the contractor and inspections passed? (A contractor who asks you to pull owner-builder permits may be unlicensed.)
• Would you hire them again without hesitation?

Step 5: Cross-reference BBB, Google, and Yelp for complaint patterns — not just star ratings. This matters because CSLB records have documented gaps: between 2020 and 2024, CSLB closed at least 10,719 complaints without investigation, meaning they never appeared on public license pages. In the Anchored Tiny Homes case, 450+ homeowners lost $12.8 million in deposits while only 10 of 55 CSLB complaints became public. Read the substance of complaints, and watch for review profiles where every review reads the same or landed in the same week.

The whole routine takes under an hour. Altadena Custom Home Builder walks clients through these five steps during every free build consultation — because in a rebuild market this active, verification is the cheapest insurance you will ever buy.

Red Flags and Recovery: What CSLB Can and Cannot Do for You

A clean CSLB record tells you a contractor is licensed — it does not tell you they're honest. The warning signs that matter most show up before, during, and after the license check.

Watch for these red flags:

• Owner-builder permit requests. A contractor who asks you to pull permits yourself transfers code compliance responsibility to you — and may be unlicensed. Legitimate contractors pull their own permits (scam-prevention guides warn).
• Bids far below competitors. CSLB's own warning: a substantially lower bid "probably indicates that the contractor made a mistake or is not including all the work quoted."
• Uniform review profiles. If every review reads the same or all landed in the same week, treat it as manufactured (verification experts advise).
• Down payments over the legal cap. California limits down payments to $1,000 or 10% of the contract price, whichever is less.

Know what CSLB can and cannot do. CSLB states plainly that "the purpose of a CSLB investigation is not to obtain restitution" — it is a regulator, not a collection agency, and consumers seeking money are directed to the courts (per CSLB's complaint page). This is why the $25,000 contractor bond matters: it is an often-overlooked recovery path that does not depend on CSLB action at all (legal analyses note). It is also why insurance verification — a Certificate of Insurance plus a direct call to the insurer — belongs in your routine.

A complaint still creates real leverage. As one California attorney puts it, "many contractors take a CSLB complaint seriously because their license is their livelihood." CSLB can also suspend the license of any contractor who fails to satisfy a final judgment substantially related to construction activities. Complaint and lawsuit work best together: the complaint builds regulatory pressure and a record; the bond claim, small claims action, or lawsuit recovers your money.

One caution: between 2020 and 2024, CSLB reportedly closed at least 10,719 complaints without investigation — meaning they never appeared on public license pages. Cross-reference BBB, Google, and Yelp for complaint patterns, not just star ratings.
