Contractor Verification Checklist: License, Bond, Insurance, Complaints

Why Altadena Homeowners Can't Skip Verification

Rebuilding after the Eaton Fire is hard enough without losing tens of thousands of dollars to someone who was never qualified to touch your lot in the first place. Yet that is exactly the risk Altadena homeowners face right now.

The numbers behind the risk are stark. Reported contractor fraud instances have risen 38% nationwide from 2023 to 2025, and the National Insurance Crime Bureau expects fraud tied to debris removal, reconstruction, and smoke cleanup to spike after the Southern California wildfires. Altadena sits squarely in that bullseye: the Eaton Fire destroyed more than 12,000 homes and structures, creating a rebuilding boom that attracts out-of-state crews seeking work in communities at their most vulnerable.

Local enforcement confirms the threat is not theoretical. On December 4, 2025, the LA County District Attorney's Consumer Protection Division filed felony charges against five unlicensed contractors operating in the Eaton Fire zone — one repeat defendant faces up to six years in state prison. In California, contracting without a license on structures damaged in a Governor-proclaimed disaster carries penalties of up to three years imprisonment and a $10,000 fine.

The most sobering local case involves two Altadena homeowners who each paid a $33,678 retainer to a man with no CSLB record, based on his claim that he was "absorbing" a license from another entity — a license that had expired. The plans he supplied bore a civil engineer's stamp that had lapsed in 2021. He then countersued, claiming each owner owed him $43,000, and placed liens on both properties.

That case exposes the core lesson: brand names, confident sales pitches, and even stamped documents are not verification. Even nationally branded franchises have engaged in predatory practices in fire zones, with franchisees operating with little oversight from parent companies, according to LAist's investigation. What protects you is a documented, independent check.

A proper verification covers four pillars:

• A valid, active CSLB license — required for any job of $1,000 or more
• An active contractor's bond, confirmed through CSLB records
• Insurance verified directly by the insurer, not a photocopied certificate
• A complaint history check, since CSLB looks back up to four years

At Altadena Custom Home Builder, we treat verification as the non-negotiable first step of any ground-up home, tear-down, or Eaton Fire rebuild project — before a single design decision is made. Skipping it can cost you far more than the rebuild itself.

Step 1: Verify the License — and What a Number Alone Won't Tell You

In the Eaton Fire zone, hiring an unlicensed contractor isn't just risky — it can be a felony crime in progress. On December 4, 2025, the LA County District Attorney's Consumer Protection Division filed felony charges against five unlicensed contractors operating in the Altadena disaster area, where contracting without a license in connection with a Governor-proclaimed disaster carries up to 3 years imprisonment and/or a $10,000 fine, according to the LA County District Attorney's office.

California law is clear on the threshold: any job of $1,000 or more requires a licensed contractor, per LA County Department of Consumer and Business Affairs. For a ground-up rebuild or Eaton Fire reconstruction, that covers essentially every project you'll consider.

Verification takes minutes. Use the CSLB "Check a License" tool at cslb.ca.gov, or call 800-321-2752. CSLB Registrar David Fogt has pointed consumers to the board's Disaster Help Center as the official resource for verifying licenses and filing complaints. But here's the critical part: a license number alone won't protect you.

Consider what happened to two Altadena homeowners hoping to rebuild after the fire. Each paid a $33,678 retainer to a man who had no CSLB record at all — he claimed he would be "absorbing" a license from another entity. That referenced license had expired on December 26, 2024, and the plans he provided bore the stamp of a civil engineer whose license expired September 30, 2021, according to ABC7's investigation. The accused has since filed countersuits and liens against the properties; the case remains in active litigation.

Before you hand over a deposit or sign anything, confirm three things:

• The license is active — not expired, suspended, or revoked.
• It's in the contractor's own name — "absorbed," "borrowed," or "pending" licenses don't count.
• The name on the license matches the person at your door and the name on your written contract.

Also check the license classification to make sure it matches the work — a general building license for a full custom home rebuild, for example. And don't rely on brand recognition as a shortcut: even nationally branded franchises can engage in predatory practices, since franchisees often operate with little direct oversight from the parent company, as LAist reported.

This is the standard we apply across every rebuild resource at Altadena Custom Home Builder, where featured builder JMB Builders LLC (CSLB #1103479) is disclosed paid placement — a license number you can and should verify yourself at cslb.ca.gov before any consultation. If a contractor resists that verification, you've learned everything you need to know.

Steps 2 and 3: Confirm Bond and Insurance Before You Sign

A license tells you a contractor is legal. Bond and insurance tell you whether you'll actually be protected if something goes wrong on your property — and skipping this step is where many homeowners get hurt financially.

Start with insurance, and use the Certificate of Insurance (COI) method. Ask the contractor to have their insurer send you a COI directly rather than accepting a paper copy handed over on the job site — a document from the contractor's hands is easy to fake or alter, while one sent from the insurance company confirms the policy is real and active. This matters because insurance industry guidance notes that homeowners insurance typically does not cover work performed by unlicensed or uninsured contractors, defective workmanship, or damage from unpermitted renovations. If an uninsured worker is injured on your property, you could face legal and financial claims as the homeowner.

Then run the insurer cross-check. Call your own insurance company and ask two questions: do they have any track record with this contractor, and will they cover the repairs this contractor performs? Insurers do keep records — reporting on wildfire-zone contractor scams found at least one contractor on an insurer's internal blacklist. A contractor who claims "your insurance will cover everything" without your insurer confirming it is waving a red flag.

On bonding, be honest about what you can verify. Licensed contractors in California are required to follow state bonding and insurance requirements, so a valid CSLB license (which you confirmed in Step 1) means bonding requirements applied at licensure. To confirm a bond is currently active, check the contractor's record through CSLB — the license lookup reflects bond status, and CSLB's Disaster Help Center is the official resource for verification questions. If a contractor hesitates or claims bonding "is being handled by a partner company," treat that the same way you'd treat a claim of an "absorbed" license: as a reason to walk away.

The stakes are real in Altadena right now. With more than 12,000 homes and structures destroyed in the Eaton Fire and the LA County District Attorney filing felony charges against unlicensed contractors operating in the fire zone, unvetted crews are actively soliciting rebuild work. Before you sign anything, confirm:

• A COI sent directly from the contractor's insurer, naming current coverage
• Your own insurer's confirmation that the contractor's work will be covered
• Active bond status visible on the contractor's CSLB record
• Consistency between the name on the COI, the bond, and the license — all should match

One mismatch — a COI issued to a different business name than the license — is enough to stop and ask questions. In our work guiding Altadena homeowners through ground-up rebuilds and Eaton Fire reconstruction, we've seen how a few extra phone calls before signing can prevent months of disputes later. If you'd like a second set of eyes on a contractor's credentials before you commit, a free build consultation is a good place to start.

Step 4: Check Complaints and Know Your Legal Protections

A contractor's license can look spotless while their complaint history tells a different story — and in California, that history is public record. The Contractors State License Board maintains a complaint system that works as both a recourse tool and a pre-hire research channel, and knowing how it operates gives you leverage before you sign anything.

Here's what many homeowners don't realize: the CSLB accepts complaints against both licensed and unlicensed contractors. Even if someone you're considering has no active license, any past complaints filed against them remain part of the record. The board addresses violations for up to four years from the date of the act, which means recent misconduct — a pattern of abandoned jobs, inflated billing, or shoddy work — will show up if it was reported.

The system also has real teeth. Under CSLB's complaint process, the board can suspend the license of any contractor who fails to satisfy a final construction-related judgment. If a homeowner wins in court and the contractor never pays, that license hangs in the balance — one more reason to search a contractor's name and license number before handing over a deposit.

California also gives you legal guardrails that no contractor can contract around:

• Any home improvement job costing more than $500 requires a written contract — a handshake deal leaves you with no enforcement path.
• Down payments are capped at $1,000 or 10% of the total project cost, whichever is less. A demand for tens of thousands upfront is a violation, not a negotiation.
• Contracts signed at your door under pressure generally carry a three-day rescission period, giving you a window to walk away from a decision you were rushed into.

Those red flags matter in Altadena right now. The NICB reports that fraudulent contractors solicit door-to-door, pressure residents to sign contracts immediately — sometimes with incomplete terms — and demand large upfront payments. In the Eaton Fire zone, the stakes are higher still: the LA County District Attorney has filed felony charges against unlicensed contractors working the disaster area, where contracting without a license can bring up to three years in prison and a $10,000 fine. As attorney Kipp Mueller, who represented Altadena lot owners, put it: people will try to rush your decision, and your best move is to step back and realize you're not in a rush.

At Altadena Custom Home Builder, we tell every Eaton Fire rebuild and custom-home client to run this complaint check alongside license, bond, and insurance verification — and to remember that a CSLB investigation protects the public but doesn't recover your money; that requires court action. Vetting a builder for a hillside lot, an SB 9 split, or a full tear-down rebuild? Our free build consultation walks you through the full verification checklist before you commit.

Your Pre-Hire Action Plan for an Altadena Rebuild

Every Eaton Fire rebuild decision carries weight, and the fastest way to protect yours is a checklist you can actually print and use. Reported contractor fraud instances rose 38% from 2023 to 2025, and the LA County DA has already filed felony charges against unlicensed contractors working the Altadena disaster zone — where more than 12,000 homes and structures were destroyed.

Before you sign anything, run every candidate through all four verification steps in order:

• License: Confirm active status at cslb.ca.gov or 800-321-2752 — required for any job of $1,000 or more. Reject any "absorbed license" story; in one Altadena case, homeowners paid $33,678 retainers each to a man with no CSLB record.
• Bond and insurance: Ask for a Certificate of Insurance sent directly from the insurer, never a photocopy. Ask CSLB to confirm bond status, since specific amounts aren't published.
• Complaints: Search CSLB's complaint records — violations are addressable for up to four years from the act.
• Contract terms: Written contract required over $500; deposits capped at $1,000 or 10% of the project, whichever is less.

Then build the habits around the checklist. Get at least three estimates, and call the LA County DCBA counselor line at 800-593-8222 if anything feels off. CSLB Registrar David Fogt encourages consumers to use CSLB's Disaster Help Center to verify a license or file a complaint. And above all, don't rush — as attorney Kipp Mueller, who represents Altadena lot owners, put it: "People are going to try to rush you to make a decision... you're not in an absolute rush."
