The National Insurance Crime Bureau reports that instances of contractor fraud increased 38 percent from 2023 to 2025, a rise it ties directly to a surge in disaster activity: 23 separate billion-dollar weather disasters hit the U.S. in 2025 alone. Most contractors are legitimate professionals running honest businesses, and the vast majority of hiring experiences go smoothly. Still, knowing the specific warning signs that separate a normal, if occasionally frustrating, hiring process from an actual scam is worth a few minutes of anyone's time before signing a contract.
License and Insurance: Verify, Don't Just Ask
Asking "are you licensed and insured" isn't enough, since the honest answer and the confident-sounding answer aren't always the same thing. In California, contractor licenses can be looked up directly through the Contractors State License Board (CSLB) at cslb.ca.gov, which shows whether a license is active, what classification it covers, and whether there's a history of disciplinary action. A legitimate contractor won't hesitate to give you their license number so you can check it yourself.
Unusually Large Upfront Deposits
The upfront deposit a contractor can request on a California home improvement contract is commonly cited as being limited to $1,000 or 10 percent of the total price, whichever is less, per CSLB guidance. If a contractor asks for significantly more than that before any work begins, that's worth asking about directly, and worth confirming the current rule with CSLB yourself, rather than assuming it's routine. There are legitimate exceptions, like custom-ordered materials that require a manufacturer deposit, but a contractor should be able to explain exactly why in that specific case.
Pressure to Sign Immediately
Legitimate contractors, even busy ones, generally give you time to review a contract and compare it against other bids. Heavy pressure to sign on the spot, "today only" pricing, or a refusal to leave a written estimate for you to review later are worth taking seriously as warning signs, particularly for larger projects.
No Written Contract, or a Vague One
A legitimate contract should spell out the scope of work, materials, a payment schedule tied to project milestones, and an estimated timeline. A contractor who wants to work off a verbal agreement, or hands you a one-page contract with no real detail, is making it much harder for you to have any recourse if the finished work doesn't match what was promised.
Cash-Only Demands or No Traceable Payment Trail
Insisting on cash, or refusing standard payment methods like check or card, removes your paper trail if a dispute comes up later. It doesn't automatically mean fraud, some smaller operations genuinely prefer it to avoid processing fees, but it's a reasonable moment to ask more questions and get everything else in writing.
No Verifiable Local Address or Long Track Record
A contractor who can't provide a real business address, or whose only footprint is a phone number and a truck, is harder to hold accountable after the fact. This is especially relevant right after a storm or wildfire, when contractors sometimes travel into an affected area specifically to take advantage of a temporary surge in demand, then move on before problems surface. This pattern was documented directly in Los Angeles County in 2026, where six unlicensed contractors were criminally charged for operating in the Palisades Fire disaster zone, collectively bidding over $1.2 million in work without a valid license.
What to Do If Something Feels Off
Trust a direct instinct that something isn't adding up, and don't feel obligated to move forward just because a contractor has already shown up or started talking numbers. Verify the license through CSLB, ask for and check references, get everything in writing, and don't be pressured into a decision faster than you're comfortable with. If you're already collecting multiple bids for the same project, a contractor who won't stand up to that basic comparison usually isn't the one you want anyway.
Frequently Asked Questions
What's the single most important thing to verify before hiring a contractor?
Their license status, checked directly through the CSLB website rather than taken on their word. It's free, takes under a minute, and shows whether the license is active and in good standing.
Is it normal for a contractor to ask for a deposit?
Yes, a reasonable deposit before work starts is standard practice. In California, that amount is commonly cited as being limited to $1,000 or 10 percent of the contract price, whichever is less, for most home improvement work. Confirm the current rule with CSLB if a request seems unusually high.
How common is contractor fraud, really?
Reported instances rose 38 percent between 2023 and 2025 according to the National Insurance Crime Bureau, with the increase tied closely to a rise in major weather disasters during that period. It remains a minority of hiring experiences overall, but it's a real and growing risk worth guarding against.
Should I be worried if a contractor's bid is much lower than the others?
Not automatically. Confirm it covers the exact same scope, materials, and timeline as your other bids first. A genuinely lower price is common when contractors have different overhead or are eager to fill their schedule, not necessarily a sign of a shortcut.
What should I do if I already paid a deposit and now something feels wrong?
Document everything in writing, including any communication with the contractor, and reach out to the CSLB directly, which maintains a disaster and general complaint hotline for exactly this kind of situation.
Are storm-chaser contractors only a problem right after a disaster?
They're most common in the days and weeks immediately after a storm or wildfire, when demand spikes and desperation makes people more likely to skip normal vetting. The same underlying red flags, no license, pressure to sign fast, cash-only demands, apply at any time of year.
Does a contractor being new or small automatically make them riskier?
No. Company size and how long they've been in business aren't reliable fraud indicators on their own. Verified license status, clear contracts, and transparent answers to direct questions matter far more than how established the business looks.
