California Contractor License Bond: Amount, Filing, and Claims

Every licensed contractor in California must carry a $25,000 California contractor license bond on file with the Contractors State License Board (CSLB) before the board will issue, renew, or reactivate a license.¹ The bond is not insurance for the contractor. It’s a financial guarantee that pays consumers, workers, and others harmed by the contractor’s conduct, and if the surety pays a claim, the contractor has to pay the surety back in full.

What the Bond Is and Who It Protects

A contractor license bond is a three-party agreement between the contractor (the principal), a surety company that backs the bond, and the public (the obligee). When a licensed contractor violates a construction contract, commits fraud, or stiffs workers, the injured party files a claim directly with the surety instead of having to sue the contractor first.²

Three groups can file claims against it:

Homeowners who suffer financial damage from defective construction or contract violations by the licensed contractor.
Anyone harmed by a willful and deliberate violation of a construction contract.
Employees owed unpaid wages or fringe benefits.

One point catches new contractors off guard: the surety isn’t absorbing the loss. If the surety pays a claim, the contractor owes that money back, plus legal costs. That reimbursement obligation is written into the surety agreement.

This bond is a licensing requirement that covers your general conduct across all your work. It does not take the place of a performance bond or payment bond on a specific project, and those project bonds don’t satisfy your license bond obligation.

Bond Amount and Premium Cost

California requires a flat $25,000 bond regardless of your trade classification or volume of work.³ A C-10 electrical contractor and a B general building contractor carry the same amount. The figure rose from $15,000 to $25,000 on January 1, 2023, under Senate Bill 607.¹

The CSLB can require double that amount — $50,000 until the next renewal — if an applicant was previously convicted of contracting without a license or cited for unlicensed work that caused substantial public harm.³

The $25,000 is the face value of the bond, not what you pay. Your actual cost is the annual premium, which the surety sets based on your credit and financial profile. Contractors with strong credit typically pay 1% to 3% of the face amount per year. That’s roughly $250 to $750 annually for the standard bond. Weaker credit pushes premiums higher and may require additional collateral or financial documentation before a surety will issue the bond.

The Second Bond Many Contractors Need

Many licensees also need a Bond of Qualifying Individual on top of the contractor’s bond. The CSLB requires it for any license qualified by a Responsible Managing Employee (RME). It’s also required when a Responsible Managing Officer (RMO) owns less than 10% of the voting stock of the corporation.¹

This bond is also $25,000 and must be written by a surety company licensed through the California Department of Insurance.¹ If a license has more than one RME or RMO, each qualifier needs their own. An RMO with at least 10% of the voting stock can claim an exemption by filing a Bond of Qualifying Individual Exemption Certification with the CSLB. Federally recognized tribes are also exempt.

The practical impact is that a corporation whose license is qualified by a non-owner RME carries $50,000 in total bond face value and pays two premiums. Factor both into your licensing budget.

Getting the Bond Issued and Filed

The bond has to come from a surety admitted and authorized by the California Department of Insurance. The CSLB publishes a search tool you can use to confirm whether a particular surety is authorized in California.⁴ Shop around. Premiums vary significantly between carriers for the same applicant.

When you apply, the surety will need your exact legal business name as registered with the state, your CSLB license number (or application fee number for new applicants), and financial documentation for underwriting. The business name and license number on the bond must match CSLB records exactly. A missing “Inc.” or an extra comma can get the filing rejected.

Most sureties now file bonds electronically with the CSLB, so the data lands in the board’s system without you mailing paper. One deadline matters: the bond must be received at CSLB headquarters within 90 days of its effective date.¹ Miss that window and the board can reject the bond. After filing, confirm it posted by checking the CSLB’s “Check a License” tool, which shows bond status in real time.

What Happens If Your Bond Lapses

If your surety cancels your bond — for nonpayment, an underwriting change, or because you switched carriers without lining up a replacement — your license goes under bond suspension immediately.⁵ Any work you perform during suspension counts as unlicensed contracting, which brings its own disciplinary exposure on top of the suspension.

You can lift a bond suspension two ways:

The surety rescinds the cancellation, with the rescission notice reaching the CSLB within 90 days of the cancellation date.
You file a new bond or a cashier’s check, received by the CSLB within 90 days of the new bond’s effective date.

Miss the 90-day window and the board may still accept a late bond and lift the suspension retroactively, but only if the lapse was due to circumstances beyond your control.⁵ Forgetting to renew doesn’t qualify. The most common way contractors land here is switching surety companies and letting the old bond cancel before the new one is on file. If you’re changing carriers, confirm the new bond is filed and showing on the CSLB system before the old one ends.

Higher Bonds After Discipline or an Unpaid Judgment

Contractors with a disciplinary history face an additional bonding requirement. If your license was previously suspended or revoked for a violation, the CSLB requires a disciplinary bond before reissuing, renewing, or restoring it. The same applies if you were an officer, partner, or qualifying individual of a company whose license was revoked while you were involved and had knowledge of the violation.

The CSLB registrar sets the amount based on the seriousness of the violation. The minimum is $25,000 and the maximum is $250,000, which is ten times the standard contractor’s bond.¹ This bond is in addition to your regular contractor’s bond and any qualifying individual bond; you can’t combine them. It stays on file for at least two years, and the registrar can extend that period. Premiums are steep because the contractor’s record signals higher risk, and some contractors in this position struggle to find a willing surety at all.

Separately, if a court enters a final judgment against a contractor and the contractor doesn’t pay, the contractor must notify the CSLB registrar in writing within 90 days. Failing to give notice brings an automatic license suspension once the registrar finds out. Even with timely notice, the contractor must post an additional bond equal to the unsatisfied judgment to keep the license active, and must file it within 90 days of notification by the board or the license is suspended automatically. The bond amount can be reduced as the judgment is paid down and goes away once the debt is satisfied.

Cash Deposit Alternative

You can post a cash deposit directly with the CSLB instead of buying a surety bond.⁶ The deposit has to equal the full $25,000, usually in the form of a cashier’s check. The CSLB holds the funds as security against potential claims.

You avoid annual premiums. The trade-off is that $25,000 sits tied up for as long as you hold the license, plus a waiting period after the license is canceled or goes inactive so that any claim periods can expire. For most contractors, paying a few hundred dollars a year in premium makes more sense than parking $25,000 with the state.

Claims against a cash deposit also work differently. The CSLB can only release funds from a deposit under a court order, so a claimant has to file a civil action rather than submit a claim to a surety.²

Filing a Claim Against a Contractor’s Bond

If you’re a homeowner or employee harmed by a licensed contractor, file your claim directly with the surety company that issued the bond, not with the CSLB.² To identify the surety, look up the contractor on the CSLB website and open the “Contractor’s Bond History” link on the license detail page. That tells you which surety was on the bond at the time of your contract.

Claims must be filed within the time frames set by the surety and applicable law. If the contractor posted a cashier’s check instead of a surety bond, you’ll need to go through a civil action; email CashBonds@cslb.ca.gov first to confirm a deposit exists.² One ceiling to be aware of: the bond caps at $25,000 total. If your damages exceed that, or if other claimants have already drawn against it, the bond alone may not make you whole.
