The California contractor license bond is a mandatory requirement for anyone holding an active contractor license through the Contractors State License Board (CSLB). It protects consumers, employees, and the state by guaranteeing that a licensed contractor operates in accordance with California's contracting laws.
This is not insurance for the contractor — it is a financial guarantee that protects the public. If a contractor violates the Contractors License Law, a valid claim can be paid out against the bond, and the contractor is then responsible for reimbursing the surety.
What Is the California Contractor License Bond?
Under Business and Professions Code § 7071.6, the CSLB cannot issue, reactivate, reinstate, or renew a contractor license unless a $25,000 contractor bond is on file. The amount rose from $15,000 to $25,000 on January 1, 2023, under Senate Bill 607.
Still Seeing $15,000?
Many older guides still list the $15,000 amount. Since January 1, 2023, the CSLB requires $25,000, so a $15,000 bond no longer meets the requirement. The Bond of Qualifying Individual rose at the same time, from $12,500 to $25,000.
Who Does the Bond Protect?
Business and Professions Code § 7071.5 lists who can make a claim on a contractor bond:
- Homeowners who contract for home improvement on their own residence and are damaged by a violation of the Contractors License Law
- Property owners who contract to build a single-family home (not intended for sale) and are damaged by a violation
- Anyone damaged by the contractor's willful and deliberate violation of the law, or by fraud in carrying out a construction contract
- Employees damaged by the contractor's failure to pay wages
- Benefit funds damaged by the contractor's failure to pay required fringe benefits
Who Needs a Contractor License Bond?
You need a California contractor license bond if you are:
- Applying for a new contractor license with the CSLB
- Renewing or reactivating an existing license
- A licensed contractor whose bond has been canceled or expired
- Changing your business structure (sole proprietor, corporation, LLC)
Other CSLB Bonds You May Need
Bond of Qualifying Individual — $25,000
If your license is qualified by a Responsible Managing Employee (RME), or by a Responsible Managing Officer (RMO) who owns less than 10% of the company's voting stock, that qualifier needs a separate $25,000 Bond of Qualifying Individual (B&P Code § 7071.9). Each such qualifier needs their own bond.
LLC Employee/Worker Bond — $100,000
Contractors licensed as a limited liability company must also carry a $100,000 bond (B&P Code § 7071.6.5), in addition to the $25,000 contractor bond. It protects employees who are not paid wages, interest on wages, or fringe benefits.
Disciplinary Bond
After a license is revoked for violations, the CSLB can require a disciplinary bond to return to licensure. It must be at least $25,000 and no more than ten times the contractor bond amount, and it must stay on file for at least two years (B&P Code § 7071.8).
Cash Deposit Instead of a Bond
The CSLB also accepts a cashier's check in place of a surety bond. The difference is that a cash deposit ties up the full amount, while a bond costs only the annual premium.
How Much Does It Cost?
You do not pay the full $25,000. Instead, you pay an annual premium — a small percentage of the bond amount based primarily on your personal credit. Stronger credit generally means a lower premium. We submit your application to several surety companies — each sets its own rate, and if one declines, we go to the next — so your premium depends on which surety approves you and isn't set until you're approved.
What Determines Your Rate?
Surety underwriters look primarily at your personal credit score, along with your business history and any past claims. As a former underwriter, our agency knows what underwriters look for and how to present your application.
How the Bond Is Filed With the CSLB
The CSLB must receive the bond at its headquarters within 90 days of the bond's effective date. When we issue your bond, we handle the filing, so you don't have to mail anything yourself. Once it's processed, you can confirm it is on file using the CSLB's online license lookup.
What If Your Bond Is Canceled or a Claim Is Paid?
- If your surety cancels the bond, the CSLB places your license under bond suspension. The suspension is lifted when a new bond is received within 90 days of its effective date.
- If a judgment or claim is paid, the bond amount is reduced, which also triggers a suspension. Filing a new bond lifts the bond suspension, but not a separate suspension for the unpaid judgment or claim.
- Work done while suspended is treated as unlicensed work and can lead to disciplinary action.
Any claim the surety pays, you must repay. Keeping your bond active and your jobs in compliance protects your license.

Why Choose Advanced Surety?
We work with multiple admitted surety companies, so your application isn't limited to one carrier's rates or rules — which matters most when credit or past claims make approval harder.
