Quick Answer
The CSLB requires three things from every licensed California contractor: (1) a $25,000 contractor license bond, (2) workers' compensation insurance or a valid WC exemption, and (3) general liability insurance for most license classifications. Failure to maintain any of these results in automatic license suspension. You can restore your license within 90 days by providing proof of coverage.
What Insurance Does CSLB Require?
The California Contractors State License Board (CSLB) requires all licensed contractors — regardless of trade or license class — to maintain three forms of financial protection as a condition of licensure. These requirements apply to every contractor in California, from Los Angeles to Sacramento to the Central Valley.
Required for all CSLB license classes. Minimum $1M per occurrence / $2M aggregate. Covers third-party bodily injury and property damage arising from your work. Most GCs and project owners require this before they'll hire you.
Required if you have any employees — including part-time, seasonal, or day-labor workers. California Labor Code §3700 mandates WC for all employers. Sole owner-operators with zero employees may qualify for an exemption (see below).
A $25,000 surety bond is required by CSLB for all license classes. This is separate from insurance — it protects consumers if you fail to complete a job or violate the Contractors License Law. We can help you obtain both.

CSLB Insurance Requirements by License Classification
Every CSLB license class — from Class A General Engineering to C-61 Limited Specialty — requires the same core insurance: General Liability and Workers' Comp (if you have employees). Below is the complete list with trade examples.
Requirements current as of 2026. Always verify with CSLB at cslb.ca.gov for your specific license classification and situation.
What Happens Step-by-Step When Your CSLB License Gets Suspended
Most contractors don't realize how fast a license suspension happens — or how visible it is. Here's exactly what occurs when your insurance lapses:
When your GL or WC policy lapses, cancels, or is not renewed, your insurance carrier is legally required to notify the CSLB directly. This happens automatically — you don't have to do anything for the CSLB to find out.
Within 30 days of receiving the lapse notice, the CSLB sends you a Notice of Suspension. At this point your license is still technically active, but you're on a countdown clock.
If you don't provide proof of new or reinstated coverage within the notice period, your license is suspended. The suspension appears immediately on the CSLB public license lookup at cslb.ca.gov — visible to any GC, property owner, or inspector who checks.
A suspended license means you cannot legally bid on, enter into, or perform any contracting work in California. Any work performed on a suspended license exposes you to civil fines up to $15,000 per violation and potential criminal charges.
To reinstate, you must: (a) obtain a new or reinstated insurance policy, (b) file proof of coverage with the CSLB, and (c) pay a reinstatement fee. We can help you get a new policy and file the paperwork fast — often same day.
Consequences of Working on a Suspended License
- Civil fines up to $15,000 per violation from the CSLB
- Criminal misdemeanor charges for contracting without a license
- Personal liability for any injuries or damages — your insurance won't cover unlicensed work
- Inability to collect payment for work performed — courts won't enforce contracts with unlicensed contractors
- Permanent damage to your professional reputation (suspension is public record)

How to File a Workers' Comp Exemption in California
If you are a sole proprietor or a corporate officer with no employees, you may qualify to file a Workers' Compensation exemption with the CSLB. Here's how it works and what to watch out for.
You qualify for a WC exemption if you are: (a) a sole proprietor with no employees, (b) a partner in a partnership with no employees, or (c) an officer of a corporation who owns at least 15% of the stock and has no employees. You must certify this status under penalty of perjury.
Complete CSLB Form 13A (Certificate of Self-Insurance or Exemption) and submit it with your license application or renewal. The form is available at cslb.ca.gov. You must re-file the exemption at each license renewal cycle — it does not carry over automatically.
California's AB 5 (2020) changed how workers are classified. Even if you hire subcontractors as 'independent contractors,' the CSLB and the state may consider them employees for WC purposes if they fail the ABC test. If your subcontractors don't have their own WC coverage, you may be required to cover them. This is a common trap — call us to verify your situation.
If you hire even one worker — even temporarily, even for a single day — your exemption is no longer valid. You must obtain WC coverage immediately. Failure to do so is a violation of California Labor Code §3700 and can result in stop-work orders, fines, and personal liability for any injuries.
Not sure if you qualify for an exemption? Call us at (858) 925-9555. We work with contractors across California every day and can tell you in minutes whether you need WC coverage or qualify for an exemption — and help you get the right coverage if you do.
CSLB Insurance FAQ — Questions California Contractors Actually Ask
Q. What insurance does CSLB require to get a contractor's license in California?
The CSLB requires all licensed contractors to maintain active General Liability insurance and a $25,000 contractor's license bond. Workers' Compensation is also required if you have any employees (including part-time or seasonal workers). The minimum GL limit accepted by CSLB is $1M per occurrence / $2M aggregate, though most GCs and project owners require the same or higher limits from subcontractors.
Q. Do I need workers' comp if I'm a sole proprietor with no employees in California?
If you are a sole owner-operator with zero employees, you may qualify for a Workers' Compensation exemption from the CSLB by filing a Certificate of Self-Insurance Exemption. However, if you hire subcontractors who are not themselves licensed and insured, you may be required to carry WC for them under California Labor Code §2750.5. The rules tightened significantly under AB 5 (2020). We recommend calling us to verify your specific situation before filing an exemption — a mistake here can cost you your license.
Q. How do I file a Workers' Comp exemption with CSLB?
To file a WC exemption, you must complete CSLB Form 13A (Certificate of Self-Insurance or Exemption) and submit it with your license application or renewal. You must certify that you have no employees and will not hire any without first obtaining WC coverage. The exemption must be renewed with each license renewal cycle. If your situation changes — even temporarily hiring one worker — you must obtain WC coverage immediately.
Q. How quickly can I get a Certificate of Insurance for CSLB?
Asena Capital Insurance Services can issue a Certificate of Insurance (COI) within 24 hours of binding your policy — often the same day. We understand California contractors often need proof of insurance urgently for job bids, permit applications, or CSLB renewals. Call us at (858) 925-9555 and we'll prioritize your request.
Q. What happens if my CSLB license lapses due to missing insurance?
If your insurance lapses, your carrier notifies the CSLB automatically. The CSLB then issues a Notice of Suspension, and if you don't provide proof of new coverage quickly, your license is suspended. A suspended license is publicly visible on cslb.ca.gov, you cannot legally work, and reinstatement requires filing proof of insurance plus a reinstatement fee. We send renewal reminders to all our clients to prevent this from happening.
Q. Does CSLB require me to name anyone as additional insured?
CSLB itself does not require a specific additional insured on your policy. However, virtually every general contractor and project owner in California requires subcontractors to name them as Additional Insured on their GL policy before starting work. This is standard practice. We can add additional insureds to your policy at no extra cost in most cases — same day if needed.
Q. What is the difference between a Certificate of Insurance and an Additional Insured endorsement?
A Certificate of Insurance (COI) is a document that proves you have coverage — it's what you show to the CSLB, a GC, or a property owner. An Additional Insured endorsement actually adds another party to your policy, giving them direct coverage under your GL if they are named in a claim arising from your work. Both are common requirements on California job sites, and both can be issued same day.
Q. What is the contractor's license bond and how is it different from insurance?
The $25,000 CSLB contractor's license bond is a surety bond — not insurance. It protects consumers (homeowners, project owners) if you fail to complete a job, cause damage, or violate the Contractors License Law. If a claim is paid from the bond, you are required to repay the surety company. Insurance, by contrast, protects you and your business from covered losses. You need both — the bond for CSLB compliance, and GL/WC insurance for actual job site protection.
