If you are planning a kitchen remodel, permitted ADU, addition, hotel renovation, or any ground-up build in Greater Los Angeles, the contractor you hire determines whether the job finishes on time, follows code, and protects your budget. Below are seven specific mistakes to check for during the first call or consultation. Each item explains why the issue matters in Los Angeles and gives one concrete verification step you can use on the spot.
The seven mistakes to check
1. Hiring a contractor without verifying their CSLB license
Why it matters: An active California State License Board license shows the contractor is legally authorized to perform the categories of work on your project. Contractors who operate outside their license class or without a current CSLB number increase the risk of unpermitted work, uninsured subcontractors, and limited recovery if problems arise. Local builder resources and Los Angeles contractors recommend checking the CSLB number before scheduling demolition or making payments.
Verification step: Ask for the contractor's CSLB license number during the initial call and verify it online before you approve any work or deposits. Confirm that the license classification covers your project type and that the license is active. If the lookup shows disciplinary actions or inactive status, treat that as a serious warning and walk away. For practical vetting tips, regional contractor guides explain why this check is the first filter many homeowners use.
2. Accepting verbal insurance or bonding claims without documents
Why it matters: General liability, workers' compensation, and bond coverage protect you from third-party injury claims, property damage, and unpaid subcontractor liens. Los Angeles projects often involve tight sites, public walkways, and multiple trades, which raises liability exposure. Industry checklists emphasize requiring certificates of insurance and bond details before work starts to avoid being financially responsible for accidents or abandoned work.
Verification step: Request a certificate of insurance (COI) and any bond documentation in writing as part of your initial email or text exchange. Ask the contractor to name your property as an additional insured if your lender or property manager requires it, and confirm the COI issuer by phone or the carrier portal before permitting work to begin. If the contractor cannot produce a valid COI or bond number quickly, consider that a red flag.
3. Signing without a written contract that meets California requirements
Why it matters: California law for home improvement contracts requires specific elements such as a clear project description, total contract price, down payment terms, a progress payment schedule, change-order language, insurance notices, and a mechanics lien warning. Missing or vague contract terms leave you with weaker dispute-resolution tools and fewer statutory protections. Builder summaries that reference BPC §7159 highlight the contract items you should expect before any work begins.
Verification step: Do not provide a down payment or allow materials to be ordered until you receive a signed, itemized contract by email. Compare the contract to the statutory checklist and ask the contractor to amend any missing language. Keep a signed copy on file and ensure that change-order authority, payment milestones, and termination terms are explicit before permitting physical work.
4. Assuming the contractor understands LA permitting and local codes
Why it matters: Greater Los Angeles is a patchwork of jurisdictions with different permitting paths and inspection rules. The City of Los Angeles, unincorporated LA County, and neighboring cities may use different forms, plan check timelines, and zoning interpretations. Contractors without recent, local permitting experience can cause long delays, incorrect permit applications, and costly rework.
Verification step: Ask which jurisdiction will issue permits for your project and request two examples of recent jobs the contractor successfully permitted in the same jurisdiction. Confirm whether the contractor pulls permits directly, uses an expeditor, and how inspections and punch-list corrections are coordinated with the local building department. Contractors with proven local experience will describe this process and provide recent permit numbers or client references.
For additional context about common permitting pitfalls and LA-focused questions to ask, practical articles from regional builders outline the kinds of jurisdictional issues you should probe during vetting.
5. Hiring without seeing references and projects like yours
Why it matters: Contractors who have completed projects similar to yours—whether a kitchen remodel, permitted ADU, or hospitality renovation—understand sequencing, subcontractor coordination, and frequent code or inspection challenges specific to that work. Seeing completed photos and speaking with recent clients gives you realistic schedule expectations and direct feedback about communication, cleanup, and warranty responsiveness.
Verification step: Request three photos of completed projects of the same scope and two recent client references, preferably a homeowner and a property manager for commercial work. Ask references about timelines, whether permits were pulled, how change orders were handled, and how warranty issues were resolved. If a contractor resists providing references or comparable project photos, treat that as a serious concern.
6. Overlooking project management and communication commitments
Why it matters: Complex Los Angeles jobs require coordinating multiple trades, inspections, and material deliveries on tight schedules. A single, named project manager reduces misunderstandings and keeps the schedule on track. Transparent communication cadence, documented change order procedures, and a clear daily or weekly update routine significantly lower cost and schedule risk.
Verification step: Ask who will be your single point of contact and request a sample weekly update or a templated project timeline. Confirm how change orders will be documented, priced, and approved. If the contractor does not assign a dedicated project manager or cannot describe a regular update process, insist that those commitments be added to the contract before work begins. For example, some firms advertise that they assign a dedicated project manager to every job and include sample progress reports; ask to see those templates.
7. Not clarifying warranty, punch-list, and post-completion support
Why it matters: Some defects or settling issues only appear after final payments and seasonal changes. A clear workmanship warranty and a formal punch-list process protect your investment and set expectations for final payment and follow-up. Without written warranty terms you may face lengthy disputes or out-of-pocket repairs for issues that should have been covered.
Verification step: Ask for a written warranty that specifies what is covered, the time period for workmanship and for major systems, and an explicit process for submitting claims after final payment. Require the warranty terms and the punch-list acceptance procedure to be included in the contract so you retain leverage for corrections and know how long follow-up is guaranteed.
What to ask next and how to get a free quote
Use this short checklist during your first phone call to rapidly filter out risky contractors:
- Ask for the contractor's CSLB license number and verify it online before any deposit.
- Request a current certificate of insurance and any bond documentation.
- Require a signed, itemized contract that includes price, payment schedule, change-order language, and lien notices before materials are ordered.
If those three items check out, move on to references, jurisdiction-specific permitting experience, and project management details. When you compare proposals, weigh not only price but the clarity of the contract, the contractor's local permitting track record, and the post-completion warranty terms.
When you are ready to get estimates, ask for an on-site consultation or a remote overview followed by a free, written quote. Many reputable firms offer a free upfront quote and assign a dedicated project manager to each job; request that in writing so it appears in your proposal.

Frequently asked questions
How do I verify a contractor’s CSLB license in Los Angeles?
Ask the contractor for their CSLB license number and check it immediately using the California license lookup. Confirm the license classification covers the work you plan and that the license is active. If the record shows disciplinary history or inactive status, treat that as a serious warning and seek another contractor.
What contract elements does California law require before work begins?
California law requires a written home improvement contract that includes the project description, total price, down payment terms, a progress payment schedule, change-order language, insurance notices, mechanics lien warnings, and a signed copy provided to the buyer before work starts. Compare any proposed contract to that checklist and ask the contractor to add missing items before you sign.
Which insurance certificates should a legitimate general contractor provide?
A reputable contractor should provide a certificate of general liability insurance and proof of workers' compensation coverage for employees. If a bond is part of the contract or required locally, request the bond number and issuer. Ask the contractor to name your property as an additional insured if your lender or property manager requires it.
How can I confirm a contractor has experience with LA permitting?
Ask for two recent examples of permitted projects in the same jurisdiction and request the permit numbers if possible. Confirm whether the contractor or a permit expeditor will pull permits, and ask how inspections and punch-list corrections will be coordinated. If the contractor is unfamiliar with local permit pathways, consider a different firm with proven local experience.
What should a workmanship warranty cover and how long should it last?
Workmanship warranties usually cover defects in labor for a defined period, commonly one year, while manufacturers provide separate material warranties. Request the workmanship warranty in writing, clarify what is excluded, and document how warranty claims are submitted and resolved after final payment.
