California surety bond requirements vary by profession, but the structure is the same across the board: you buy a bond in a fixed dollar amount set by statute, pay an annual premium that is a small percentage of that amount, and file the signed bond with the agency that issues your license. The face amounts range from $15,000 for a notary public to $25,000 for a contractor and $50,000 for a motor vehicle dealer. The premium you actually pay is usually 1% to 10% of the bond amount per year, depending mostly on your credit.
How a California Surety Bond Works
A surety bond is a three-party contract. You are the principal. The government agency that requires the bond is the obligee. A surety company backs the guarantee. If you violate the law or breach a duty the bond covers, the harmed party files a claim with the surety, and the surety pays valid claims up to the bond’s face value.
This is the part most applicants miss: a surety bond is not insurance. After the surety pays a claim, it comes after you for every dollar, plus its legal costs. Before issuing the bond, the surety requires you to sign an indemnity agreement that makes you personally liable for payouts. If your business is an LLC or corporation, the surety will typically require personal guarantees from owners holding 10% or more. The bond protects the public, not you.
Bond Amounts by License Type
Contractor License Bond
Every active contractor license in California requires a $25,000 bond filed with the Contractors State License Board. This covers new licenses, renewals, reinstatements, and reactivations. A license that has been formally inactivated with the CSLB doesn’t need a bond.1California Legislative Information. California Business and Professions Code 7071.6
The $25,000 is not a per-project limit. It is the total available across all claims during the bond term.2Contractors State License Board. Fast Facts – A Guide to Contractor License Bonds The statute splits that pool into two tiers. Homeowners who hired the contractor for home improvements or single-family home construction, fraud victims, unpaid employees, and unpaid fringe-benefit funds can claim the full $25,000.3California Legislative Information. California Business and Professions Code 7071.5 Everyone else is capped at an aggregate of $7,500.1California Legislative Information. California Business and Professions Code 7071.6
If you were previously convicted or cited for unlicensed contracting that caused substantial public injury, the CSLB can double your bond to $50,000 until your first renewal.1California Legislative Information. California Business and Professions Code 7071.6
There is also a separate $25,000 qualifying individual bond when the person who qualifies the license is not the business owner, a general partner, or a joint licensee. It cannot be combined with the contractor’s license bond.4California Legislative Information. California Business and Professions Code 7071.9 A company whose qualifier is an employee rather than an owner needs $50,000 in total bond coverage just for licensing.
Motor Vehicle Dealer Bond
California requires a $50,000 surety bond from every motor vehicle dealer before the DMV will issue or renew a dealer license. Remanufacturers also need $50,000. Dealers who sell exclusively motorcycles or all-terrain vehicles need $10,000.5California Legislative Information. California Vehicle Code 11710
The dealer bond protects purchasers, sellers, financing agencies, and government agencies against fraud or fraudulent representation that causes monetary loss. Unlike the contractor bond, it must stay at full value at all times. If a judgment or claim payout drops the bond below $50,000, the dealer’s license is automatically suspended until the bond is restored or the judgment is resolved.5California Legislative Information. California Vehicle Code 11710
Notary Public Bond
Every California notary public must execute a $15,000 bond from an admitted surety insurer. A cash deposit cannot be substituted.6California Legislative Information. California Government Code 8212 The bond covers official misconduct or neglect, and both the notary and the surety are liable for damages in a civil action.7Notary of America. California Government Code – Notary Public Provisions
The bond does not cover general errors and omissions. Notary E&O insurance is a separate product, not legally required in California, that many notaries carry voluntarily.
Court Bonds Are a Different Category
If you are posting a bond because of a lawsuit rather than a license, the rules sit elsewhere. Appeal bonds in California run one and a half times the judgment amount from an admitted insurer, or double from personal sureties.8California Legislative Information. California Code of Civil Procedure 917.1 Probate bond amounts are set by the court based on the estate’s personal property, expected income, and (where applicable) real property.9Justia Law. California Probate Code 8480-8488 These are not licensing bonds and don’t follow the application process below.
What You’ll Actually Pay
The bond amount and your premium are two different numbers. The amount is the maximum the surety will pay on claims. The premium is your annual cost of maintaining the bond, calculated as a percentage of the face amount.
With strong credit (roughly 675 and above), premiums typically run 1% to 3% of the bond amount. On a $25,000 contractor bond, that is $250 to $750 a year. Average credit (600 to 675) pushes premiums to 3% to 5%. Below 600, expect 5% to 10%, which can mean up to $2,500 a year on the same contractor bond.10Lance Surety Bonds. How Much Does a Surety Bond Cost in 2026? Past bankruptcies, judgments, or disciplinary actions can push rates higher or trigger a collateral requirement.
Probate bond premiums typically run 0.5% to 1% of the bond amount, reflecting a lower risk profile than active business operations.10Lance Surety Bonds. How Much Does a Surety Bond Cost in 2026? Premiums are generally deductible as an ordinary business expense. If you prepay a premium covering more than one year, deduct only the portion for the current tax year.
Applying for the Bond
The information a surety will ask for is straightforward but has to be exact. You’ll need your business entity name as registered with the California Secretary of State (or your personal name for an individual license), your California license number or application tracking number, and a Social Security Number or Federal Employer Identification Number for the background and credit check.
Contractor bonds use CSLB Form 13L-1, available on the CSLB website.11Contractors State License Board. Forms and Applications Notary bond forms come through the Secretary of State’s office or approved private vendors. In either case, the bond form must be signed by the principal, countersigned by the surety’s authorized representative, and bear the surety’s corporate seal.
For higher-dollar or higher-risk bonds, the surety may ask for detailed financials: a balance sheet, income statement, and work-in-progress schedule. Contractors seeking bonds on large public works projects routinely provide this level of documentation. The surety’s underwriters review your financial stability, cash flow, and net worth before setting the premium and agreeing to issue the bond.
Where the Bond Gets Filed
Filing depends on the license.
Contractor bonds go to the CSLB, which accepts electronic filings. Most sureties transmit bond information directly into the CSLB’s database, and your license record updates almost immediately. Confirm with your surety that the electronic submission went through; a gap in bond coverage triggers automatic suspension.
Notary bonds take a different path. The bond and your oath of office go to the county clerk in the county of your principal place of business, not to the Secretary of State directly.12California Secretary of State. File Notary Public Oath and Bond You have 30 days from the start date on your commission to file. Miss that window and your commission never takes effect.13California Legislative Information. California Government Code 8213 You can take the oath at the county clerk’s office with valid photo ID, or before another notary in the same county and then mail the documents to the clerk by certified mail.
County clerk fees vary. Los Angeles County charges a $23 registration fee plus a $20 recording fee for the first page of the bond, with $3 per additional page.14Los Angeles County Registrar-Recorder/County Clerk. Notary Public Oath and Bond Fees San Diego County combined fees can approach $80 to $100.15San Diego County Assessor/Recorder/County Clerk. Notary Public Oath and Bond Filing Check with your clerk before filing so you include the right payment, and don’t wait until the last day of your 30-day window because paper filings can take several weeks to process.
Motor vehicle dealer bonds go directly to the DMV with the dealer license application or renewal. The bond must include a written appointment designating the DMV Director as your agent for service of process in any claim arising from the bond.5California Legislative Information. California Vehicle Code 11710
What Happens If Your Bond Lapses
Letting the bond lapse is one of the fastest ways to lose your California license. For contractors, a surety’s cancellation of a required bond triggers automatic license suspension. A bond reduced below its required amount by a judgment payout does the same thing. To reinstate, the surety must send a rescission of cancellation notice to the CSLB, or you must get a new bond and submit it within 90 days.16Contractors State License Board. Major Reasons for Suspension and How to Reinstate Your License Any work performed during the suspension counts as unlicensed contracting, with its own penalties.
Motor vehicle dealers face automatic suspension the moment the bond drops below full value. No grace period.5California Legislative Information. California Vehicle Code 11710
For notaries, a lapsed bond makes the commission effectively void. If you move your principal place of business to a different county, you need to file a new oath and bond (or a duplicate of the original) with the new county clerk within 30 days.13California Legislative Information. California Government Code 8213
If Someone Files a Claim Against Your Bond
Claims go to the surety, not to you directly. The surety investigates, pays what it determines is valid up to the face amount, and then invokes the indemnity agreement you signed to collect from you. On a contractor bond, a claim window extends up to two years from the original license expiration date even if the license has been revoked, so long as the violation happened before the revocation.2Contractors State License Board. Fast Facts – A Guide to Contractor License Bonds
Because you are on the hook for repayment, cooperate with the surety’s investigation and dispute any claim you believe is invalid before the surety pays it. Once the surety has paid, your argument shifts from whether the claim had merit to how quickly you can reimburse the surety and keep your license intact.
