If you’re planning to work as a general contractor in California, understanding the licensing rules and insurance requirements is essential. California has some of the strictest contractor laws in the U.S., designed to protect homeowners, workers, and businesses. This guide breaks down California general contractor license and insurance requirements in simple, clear language so you know exactly what to expect — from getting your license to staying insured and compliant.
Do You Need A License To Be A General Contractor In California?
Yes. California law requires anyone who bids on or performs construction work worth $500 or more (labor and materials combined) to hold a valid contractor license from the Contractors State License Board (CSLB).
This rule applies whether you’re a solo contractor, a small business, or a startup.
Unlicensed contracting in California can lead to:
- Fines up to $15,000
- Misdemeanor charges
- Loss of the ability to file liens or collect payments
How To Get A General Contractor License
To get a California general contractor license, you must:
- Meet experience requirements
You need 4 years of journey-level construction experience in your trade. - Submit an application
Apply through the CSLB and pay the required fees. - Pass two exams
- The Law & Business exam
- The trade-specific exam for your classification (usually “Class B – General Building”)
- The Law & Business exam
- Provide fingerprints for background checks
- Secure a $25,000 contractor license bond (required for all contractors)
Most applicants take 3–6 months from application to approval.
Insurance Requirements For California General Contractors
Insurance is a major part of California general contractor license and insurance requirements. While not all insurance types are legally required, many are needed for compliance, jobsite approval, and client trust.
Here’s what contractors typically need:
General Liability Insurance
Protects against accidental property damage, injuries to others, or legal claims.
- Average cost: $850–$3,500 per year
- Typical limits: $1M per claim / $2M aggregate
- Example: If you accidentally damage a client’s $6,000 floor, this policy pays for repairs.
Liability insurance isn’t required by the state, but most clients and commercial jobs will not hire you without it.
Workers’ Compensation Insurance
Required if you have any employees—even part-time or temporary.
- California is strict: the CSLB will suspend your license if your workers’ comp lapses.
- Roofing contractors must carry workers’ comp even with zero employees due to high injury risks.
Average cost by trade (per $100 in payroll):
- Carpenters: $6–$12
- Electricians: $4–$9
- Roofers: $20–$45
Commercial Auto Insurance
Required for work vehicles used to transport tools, materials, or staff.
- Average cost: $1,200–$2,800 per vehicle annually
- Protect your business if your vehicle causes damage or injury.
Tools & Equipment Coverage
Covers stolen or damaged tools—important in California where tool theft is common.
- Average cost: $150–$500 per year for $10,000 in coverage
Builders Risk Insurance
Covers buildings under construction from fire, vandalism, and weather damage.
- Cost: 1–3% of project value
California Surety Bond Requirements
The CSLB requires every contractor to carry a $25,000 contractor license bond. This bond protects the public, not the contractor.
If a contractor violates state laws, leaves a job incomplete, or fails to pay workers, the bond compensates affected parties.
Cost to the contractor:
- Typically $100–$250 per year with good credit
- Higher for poor credit or past claims
Local Contractor Requirements In California
Local cities and counties can add their own rules, including:
- Business licenses
- Local building permits
- Job-specific insurance limits
- Proof of workers’ comp or liability coverage
Examples:
- Los Angeles requires a business tax registration certificate.
- San Francisco often requires higher liability limits for commercial projects.
Always check your local building department before starting work.
California Contractor License Renewal
Your contractor license must be renewed every two years.
To renew, you must:
- Pay renewal fees
- Keep your contractor bond active
- Maintain workers’ comp coverage (if required)
- Update business information if anything changes
Failing to renew leads to automatic suspension and loss of jobsite eligibility.
California Contractor License Reciprocity
California has reciprocity agreements with:
- Arizona
- Nevada
- Louisiana
This allows experienced contractors licensed in these states to skip the trade exam in California.
You still must:
- Pass the California Law & Business exam
- Provide proof of experience
- Submit fingerprints
- Get bonded and insured
