The Core License Bond Requirement

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.

Additional Bonds You Might Need

• 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.

Project-Specific Bond Requirements

• 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.

What Bonds Cost—and Why Prices Vary

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.

How Claims Work—and How to Avoid Them

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.

Strategies for Lowering Bond Costs

• 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.
