To choose a reliable general contractor in Los Angeles, verify their CSLB license at cslb.ca.gov, confirm they carry at least $1 million in general liability insurance, and check for specific experience with your project type. As of 2026, there are over 90,000 active licensed contractors in LA County, but fewer than 20% specialize in residential new construction and fire rebuilds.

As a licensed general contractor (CSLB #1137900) based in Sherman Oaks and working across Greater Los Angeles, I have seen both excellent and terrible contractor work. This guide covers exactly what to look for so you hire the right GC for your project, whether it is a fire rebuild in Altadena, an ADU in Pasadena, or a full remodel in Pacific Palisades.

How Do You Verify a Contractor's License in California?

Visit cslb.ca.gov and search by license number or name. Every general contractor in California must hold an active Class B license from the Contractors State License Board (CSLB). The search results will show:

• License status (active, expired, suspended, or revoked)
• License classification (Class B for general building)
• Bond status and workers' compensation insurance
• Any complaints, disciplinary actions, or citations
• Business name and address

Never hire an unlicensed contractor. In California, it is illegal for anyone to perform work valued at $500 or more without a valid CSLB license. Unlicensed work voids your homeowner's insurance coverage and leaves you with no legal recourse if something goes wrong.

What Insurance Should a General Contractor Carry?

At minimum, your contractor should carry general liability insurance ($1 million minimum) and workers' compensation coverage. Ask for current certificates of insurance and verify them directly with the insurance provider.

What Questions Should You Ask a General Contractor Before Hiring?

Ask these 10 questions during your initial consultation. The answers will quickly separate professionals from amateurs:

1. What is your CSLB license number? Verify it before the meeting.
2. Do you carry general liability and workers' comp? Ask for certificates.
3. Have you completed projects similar to mine? Request photos and references.
4. Are you familiar with permitting in my area? LA County, City of LA (LADBS), and Pasadena all have different processes.
5. Who will be on-site managing the project daily? The owner should not be the only point of contact.
6. Can you provide a detailed written estimate? Line-item breakdowns by category, not lump sums.
7. What is your typical project timeline? Compare this to industry standards for your project type.
8. How do you handle change orders? Get this in writing before signing.
9. What is your payment schedule? California law limits deposits to $1,000 or 10% of the contract price, whichever is less.
10. Will you pull all permits? A reputable contractor always pulls permits. Unpermitted work can cost you tens of thousands in fines and rework.

What Are the Red Flags When Hiring a Contractor in Los Angeles?

Watch for these warning signs that indicate an unreliable or potentially fraudulent contractor:

• No CSLB license or refuses to share it -- walk away immediately
• Demands large upfront payments -- California law caps initial deposits at $1,000 or 10%
• No written contract -- all projects over $500 require a written contract by law
• Significantly lower bid than competitors -- usually means cut corners, unlicensed subs, or change orders later
• Pressure to start immediately -- legitimate contractors have lead times
• No physical business address -- PO boxes only are a red flag
• Cannot provide recent local references -- they should have 3-5 verifiable projects

How Much Should a General Contractor Cost in Los Angeles?

General contractor fees are typically structured as a percentage of total construction costs or a fixed fee. As of 2026 in Greater Los Angeles:

Be wary of contractors who charge less than 10%. Managing a construction project in Los Angeles requires significant overhead -- permits, insurance, supervision, scheduling -- and margins below 10% often lead to cut corners or abandoned projects.

Why Does Local Experience Matter for LA Construction?

Los Angeles has one of the most complex permitting environments in the country. A contractor familiar with your specific jurisdiction saves you months of delays:

• City of LA (LADBS): Uses ePlanLA for digital submissions; express permits available for simple projects
• LA County: Separate department handles unincorporated areas like Altadena
• Pasadena: Has its own building department with unique requirements
• Coastal zones (Pacific Palisades, Malibu): California Coastal Commission review adds 2-6 months

Key Takeaways

• Always verify CSLB license at cslb.ca.gov before hiring
• Require $1M+ general liability and workers' comp certificates
• Ask for 3-5 recent local references with similar project types
• Get detailed written estimates with line-item breakdowns
• California law caps deposits at $1,000 or 10% of contract price
• Local jurisdiction knowledge (LADBS, LA County, Pasadena) saves months
