    Questions to Ask Before Hiring a Remodeling Contractor in Los Angeles

    Before signing any renovation contract, ask every contractor 12–15 specific questions that reveal their experience, transparency, and professionalism. A contractor who becomes evasive or pressures you when you ask these questions is telling you something important.

    About Their Qualifications

    1. "What is your CSLB license number, and can I verify it before we proceed?"
    A legitimate contractor gives this immediately. Verify yourself at cslb.ca.gov. Never skip this step.

    2. "Can you provide a certificate of insurance directly from your broker?"
    Ask for general liability (minimum $1M per occurrence) and workers' compensation. The certificate should come from their insurer, not from them — documents can be falsified.

    3. "How long have you been working in Los Angeles, and which jurisdictions do you have experience with?"
    LA's permitting environment varies by city (LADBS, Santa Monica, Culver City, Beverly Hills). Local jurisdiction knowledge is meaningful.

    4. "Who specifically will be on site managing my project day-to-day?"
    Many homeowners hire based on the salesperson, then get a different site supervisor. Confirm who you're actually working with.

    About Their Process

    5. "Walk me through how you'd sequence this project from day one."
    A confident contractor describes the sequence clearly: permits → demo → rough-in → inspections → close → finish trades. Vague answers signal inexperience.

    6. "What are the biggest risks on a project like mine, and how would you handle them?"
    A contractor who can articulate specific risks — and specific solutions — has done this before. Generic answers are a yellow flag.

    7. "How do you handle change orders?"
    The right answer: written change orders with itemized costs, signed before work proceeds. Any answer involving verbal authorizations is a red flag.

    8. "Are you pulling all permits for this project? Which permits will be required?"
    A licensed contractor should pull permits in their name. If they suggest you pull them as "owner-builder" to save money — that shifts all legal liability onto you.

    About Their Subcontractors

    9. "Which subcontractors would you use for this project? Are they your regulars?"
    Established sub relationships mean predictable quality and scheduling. First-time sub relationships carry more risk.

    10. "Are your subcontractors licensed and insured?"
    The GC's insurance doesn't automatically cover subcontractors' work. Ask explicitly.

    About Their Financials

    11. "What deposit do you require?"
    Under California law, licensed contractors cannot require more than 10% or $1,000 upfront, whichever is less. Any request for 20–50% upfront is a serious red flag.

    12. "How do you manage cash flow across multiple projects?"
    A contractor who draws from one client to fund another is a serious financial red flag.

    About Their References

    13. "Can I speak with three past clients whose projects are similar to mine?"
    Always ask for, and always call, references. Ask specifically about how problems were handled.

    14. "Can you give me an address where I can look at your exterior work?"
    Legitimate for roofing, ADUs, additions, and exterior work.

    15. "If something you thought was straightforward turns out to be complicated, how have you handled that with past clients?"
    Real examples are what you're listening for. This reveals character more than any other question.

    Questions That Should Make You Pause

    • "We don't need a written contract for a job this size" — In California, any home improvement work over $500 requires a written contract.
    • "I can start tomorrow" — Good contractors are in demand. Immediate availability can mean they just lost another job.
    • "Don't worry about permits, I know the inspectors" — This is an invitation to unpermitted work. Decline.
    • "This price is only good if you decide today" — High-pressure sales tactic, not legitimate business practice.
    • "References are private / I can't share them" — Contractors with satisfied clients share references freely.
