A professional contractor should welcome verification. The company name, license number, insurance, scope, payment schedule and permit responsibility should be easy to identify before you pay a deposit. If information changes between the advertisement, proposal and contract, pause until it is resolved in writing.
This checklist is for prevention, not suspicion. Los Angeles has many qualified contractors, and ordinary business differences are not evidence of fraud. The goal is to recognize objective warning signs and use the California protections available to every homeowner.
Common contractor warning signs
- No license number on the bid or advertisement. California requires licensed contractors to identify themselves properly. Verify the number independently at cslb.ca.gov and confirm the business name matches.
- A large upfront deposit. A request for a third or half of the project before work begins conflicts with California’s home-improvement deposit limit. Do not let urgency replace a written schedule.
- Cash only. Cash is difficult to document. Use traceable payments tied to the contract and retain receipts, invoices and signed change orders.
- “We don’t need a permit.” Some cosmetic work does not need one, but structural changes and many plumbing, electrical, gas, mechanical, roofing, addition and ADU projects do. Confirm with the building department.
- Door-to-door pressure after storms. A roof concern may be real, but an immediate signature is not required to investigate it. Ask for the license, written assessment and time to compare.
- No written contract. A text thread or verbal promise cannot replace a California home-improvement contract stating the parties, scope, price, dates and payment schedule.
California protections every homeowner should use
The Contractors State License Board public record is the first check. Confirm that the license is active, the classification covers the work and the legal name is the same one collecting payment. Review the complaint and disciplinary information disclosed on the record rather than relying only on a screenshot supplied by the bidder.
Licensed contractors must maintain a $25,000 contractor’s bond. The CSLB record shows the bond company and status. Also request a current liability insurance certificate and check workers’ compensation coverage or the exemption shown on the CSLB record. A bond, liability policy and workers’ compensation serve different purposes; one does not replace the others.
For a California home-improvement contract, the down payment is generally capped at $1,000 or 10% of the contract price, whichever is less. Progress payments should not exceed the value of work performed or materials delivered. Each milestone should be understandable before construction starts.
Many contracts signed at a homeowner’s property carry a three-business-day right to cancel, and the required notice should appear in the contract. Every change order should also be in writing and signed before the added work proceeds, with the scope, cost and schedule effect clearly stated.
Ask for conditional lien releases when making progress payments and unconditional releases after payments clear, including from major subcontractors and suppliers. These documents help protect the property from mechanics liens for work or materials that the homeowner believed had already been paid.
What a legitimate written estimate looks like
A useful estimate identifies the property, contractor, license number and exact project. It breaks the work into understandable phases: protection and demolition, design or engineering, permit responsibility, structural work, systems, fixtures and finishes, cleanup and final inspection. Allowances should state what they cover instead of appearing as unexplained lump sums.
The estimate should separate included work from exclusions and explain how unknown conditions will be handled. No contractor can see behind every wall, but a professional proposal can state what has been inspected, what remains unknown and how a discovery becomes a written change order rather than a surprise invoice.
Dates and payments should connect to the scope. The agreement should identify an approximate start and completion period, describe dependencies such as plan check or owner selections, and tie payments to visible progress. Compare bids line by line, not only by total. Our Los Angeles contractor checklist provides a fuller review sequence.
What to do if you believe you have been scammed
First, preserve the record. Save the contract, proposal, advertisements, checks or transfers, invoices, text messages, emails, photographs, permit information and a timeline of events. Avoid altering documents or relying on memory when a written record is available.
The Contractors State License Board accepts consumer complaints and provides a public consumer hotline and complaint process. Contact the CSLB through its official website for current instructions. If a bond is listed, contact the surety to ask about its claim requirements. A bond claim has its own documentation and deadlines.
Depending on the amount and facts, small claims court or advice from a qualified California attorney may be appropriate. Local law enforcement may also be relevant where there is suspected theft or deliberate fraud. This guide is general information, not legal advice; an attorney can evaluate the specific contract and available remedies.
