License and permit bonds: who needs one and how they work
A license or permit bond is a surety guarantee a government requires before licensing you. Real amounts, how claims work, and what a lapse does to the license.
A license or permit bond is a surety bond that a government agency requires before it will license you or issue a permit. It guarantees that you will follow the licensing law, and it gives people you harm a way to be paid. The agency is the obligee, the public is the beneficiary, and you, the principal, must repay the surety if it pays a valid claim. The bond does not protect you and it is not a substitute for liability insurance.
What the bond promises
The bond's condition is simple: the licensee will comply with the statute and the rules of the licensing program. When someone is hurt by a violation, such as an unfinished job, unpaid wages, an unpaid carrier or a false claim for payment, they can claim on the bond. The surety investigates, pays valid claims up to the bond amount and then bills the principal under the general indemnity agreement. For small bonds, the surety often underwrites on the owner's personal credit instead of a full financial package (what a surety bond costs and how it is priced).
Two features surprise first-time buyers. First, the penal sum is an aggregate for all claimants during the bond term, not a per-job or per-claim amount. California's $25,000 contractor bond is the same $25,000 whether the contractor does two jobs or two hundred. Second, the bond is a credit, not a policy: if the surety pays $15,000 to a homeowner, you owe it $15,000 plus expenses.
Examples with amounts
Bond requirements are set by each licensing agency, so the amounts and forms differ by state, city and industry. These examples are drawn from the rule text.
| Program | Bond | What it protects |
|---|---|---|
| California contractor license (CSLB) | $25,000 contractor bond; the same amount for a bond of qualifying individual; raised from $15,000 effective January 1, 2023 under SB 607, per CSLB | Consumers damaged by license-law violations or defective construction, and employees owed wages |
| Federal property broker registration (FMCSA) | $75,000 surety bond (Form BMC-84) or trust fund (Form BMC-85), under 49 CFR 387.307 | Shippers and motor carriers if the broker fails to carry out its contracts |
| Medicare DMEPOS supplier enrollment | $50,000 continuous bond for each NPI, plus an additional $50,000 bond for each new practice location, under 42 CFR 424.57(d) | CMS and the Office of Inspector General for unpaid claims, penalties and assessments, payable within 30 days of CMS's notice |
Other common license and permit bonds, whose amounts and rules come from your state or city: motor vehicle dealers, notaries, mortgage brokers, collection agencies, sales-tax and fuel-tax accounts, money transmitters, auctioneers, and street-opening or right-of-way permits. If you are a trucking company rather than a broker, your obligation is liability insurance, not a bond; see FMCSA insurance requirements and filings for motor carriers.
The FMCSA example shows a point to check on every bond: registration stays in effect only while a bond or trust fund is in effect, and a surety bond may be cancelled only on 30 days' written notice to FMCSA. In California, the contractor bond must be in place before CSLB issues, reactivates or renews an active license. A lapse in the bond is a lapse in the license. Both programs also allow an alternative to the surety: a trust fund with a financial institution for the FMCSA broker bond, and a cashier's check for the CSLB bond. Posting cash or a letter of credit ties up working capital, which is why most licensees buy the bond.
Who gets paid, and how a claim goes
CSLB's consumer guide (Fast Facts, rev. August 2025) shows the typical claim path. A homeowner damaged by a license-law violation, a victim of fraud, and employees owed wages or fringe benefits can claim. The claimant identifies the surety through the license lookup, sends the contract, payment records and proof of the violation, and the surety investigates before it decides whether to pay. A claimant unhappy with the answer can go to small claims court for amounts up to $10,000, or superior court above that. A claim can still be made after a revocation: for events before the revocation, the claimant has up to two years from the license's original expiration date (Business and Professions Code section 7071.11, cited by CSLB). CSLB notes that its license discipline and the surety's claim investigation run separately.
Hypothetical example. A remodeler in California takes a $12,000 deposit on a $30,000 kitchen job and abandons the site. The homeowner files a claim with the surety listed on CSLB's license page. The surety investigates, finds a license-law violation and pays the homeowner a portion of the deposit, subject to the statute's limits on claims. It then bills the contractor for the payment plus costs. The bond has less available for the next claimant. Whether a claim is valid is for the surety and, if disputed, the courts.
If a notice arrives from your surety, respond at once with your side of the story and the documents. CSLB's guide says as much. An ignored claim can be paid on the claimant's version alone and still be billed to you.
How to buy one
- Get the exact bond form from the agency. Many agencies reject a substitute form, wrong obligee name or wrong amount. Some require electronic filing by the surety.
- Match the license name. The principal's name on the bond must match the license or registration, and a name or address change usually needs a rider.
- Apply with a surety agent. Small bonds are often approved on a short application and a credit check; larger or riskier bonds may ask for financial statements.
- File with the agency before the deadline, and keep proof of filing.
- Calendar the renewal. Most license bonds are annual. Some are continuous until cancelled. A missed renewal can suspend the license or registration.
- Check what else the license requires. Many licenses also require general liability, workers' compensation or other insurance. Use workers' comp and benefits requirements by state and see is business insurance required by law?.
What it costs
The premium is a percentage of the bond amount, set by the applicant's credit and financial strength, the bond type and its loss history. Because the price turns on you and not on pooled claims, applicants with weak credit pay more and may be declined, while strong applicants pay a small fraction of the bond amount. what a surety bond costs and how it is priced explains the rating factors, and the surety bond cost calculator gives an estimate once you know the bond amount. Surety premiums are usually treated as fully or largely earned when the bond is issued, so cancelling mid-term typically returns little or nothing (minimum earned premium).
Key takeaways
- A license or permit bond protects the public and the agency, not the licensee, and you must repay the surety for any valid claim.
- The bond amount is an aggregate for all claimants in the term, set by the agency, such as California's $25,000 contractor bond, $75,000 for FMCSA brokers and $50,000 for each Medicare DMEPOS NPI.
- Use the agency's form and exact legal name. A lapse in the bond can suspend the license.
- Answer a claim notice from your surety promptly, and keep your own records of the work.
- Bonds do not replace insurance. Most licenses want both; check each agency's rules.
