Top 5 Red Flags to Watch for When Hiring a Contractor

Hiring a contractor is one of the most significant financial decisions a homeowner can make, and choosing the wrong one can result in substandard work, incomplete projects, and serious legal headaches.

In California, licensed contractors are regulated by the Contractors State License Board (CSLB), yet complaints and disciplinary actions remain disturbingly common. Knowing the warning signs of a problem contractor before you sign anything can protect your home and your finances.

The first red flag is an unlicensed contractor or one whose license you have not independently verified. California requires contractors performing work valued at $500 or more in labor and materials to hold a valid CSLB license. You can verify any contractor's license status, bond, and insurance at www.cslb.ca.gov in a matter of minutes. A contractor who cannot provide a license number, or whose license turns out to be expired, suspended, or in another person's name, should be disqualified immediately regardless of how attractive their bid appears.

The second red flag is a demand for a large upfront cash payment. As noted above, California law caps initial deposits at 10% of the contract price or $1,000, whichever is less. Any contractor who insists on a substantially larger cash payment before work begins—particularly one who claims the money is needed to purchase materials—is operating outside the law and may have no intention of completing your project. Legitimate contractors have established credit relationships with suppliers and do not need excessive deposits to get started.

Third, be wary of contractors who cannot or will not provide references, a physical business address, or proof of workers' compensation and general liability insurance. A legitimate, established contractor will have a verifiable business history and will carry the required insurance without hesitation. If a contractor is injured on your property and lacks workers' compensation coverage, you may be liable for their medical expenses. Similarly, if a worker damages your home or a neighbor's property and the contractor has no liability insurance, you could be left holding the bill.

Fourth, watch for unusually low bids that seem too good to be true—they usually are. A bid that is dramatically lower than competing estimates often signals that the contractor plans to use inferior materials, skip required permits, or simply abandon the job once the deposit clears. Always request at least three written bids and be suspicious of any outlier on the low end. Finally, the fifth red flag is a contractor who discourages you from pulling permits. Required permits protect you as the homeowner; unpermitted work can create serious problems when you try to sell the property or file an insurance claim, and the cost to remediate unpermitted work often far exceeds the original savings.
