California’s Contractors State License Board (CSLB) requires most contractors to keep a $25,000 license bond on file at all times. This protects consumers, employees, and the industry from damages caused by violations of law or unfinished work.
Applies to all contractor classifications—general, specialty, and engineering.
Must be issued by a surety licensed with the California Department of Insurance.
Required before a license is issued, renewed, or reactivated.
Bond of Qualifying Individual
– A separate $25,000 bond if your license is qualified by an RME or an RMO owning less than 10% of the company.
Disciplinary Bond
– Required after a license revocation, sometimes reaching $250,000, and always in addition to the main license bond.
Payment Bonds – Mandatory for public works over $25,000 under California’s Little Miller Act, guaranteeing payment to subcontractors, suppliers, and workers.
Performance Bonds – Often required for large public or private projects to ensure completion per contract terms.
The $25,000 license bond can cost anywhere from $128 to $2,500+ annually. Pricing depends on:
Credit score (biggest factor)
Years in business and experience
License classification risk level
Claims history
Financial health of the business
Multi-year bonds can reduce costs by 12–21% compared to annual renewals, but are best for contractors with stable credit.
A claim against your bond means the surety pays out and then seeks repayment from you.
Why it matters:
Even one claim can raise your rates or limit your bonding capacity.
Non-payment of premiums can cancel your bond, suspending your license.
Good documentation, clear contracts, and timely dispute resolution reduce risk dramatically.
Boost your credit score to move into a better pricing tier.
Use an independent bond agent to shop multiple carriers.
Bundle bonds with the same surety for relationship pricing.
Lock in multi-year terms if your credit is steady.
Coordinate insurance and bonding for package savings.
Navigating California’s bond requirements is simpler once you know exactly what’s required, how much it should cost, and which steps help keep premiums low. Rising bond amounts and evolving regulations make it more important than ever to review your coverage, understand your options, and build a strong relationship with a bond professional who can guide you.
By taking action now—checking your credit, reviewing your current bonds, and comparing rates—you can protect your license, control your costs, and position your business for long-term success in California’s competitive construction market.
