What a license bond is
A contractor license bond has three parties, not two. You are the principal, the party whose conduct is guaranteed. A surety company issues the bond and stands behind that guarantee with its own balance sheet. The obligee is the party the guarantee runs to. For a license bond, that is the state agency that licenses or registers you.
That third party is the whole difference between a bond and an insurance policy. An insurance policy is an agreement between you and an insurer about your losses. A license bond is a promise a surety makes to the state about your conduct, and you sign an indemnity agreement standing behind it.
You do not file a license bond because you want the protection. You file it because the agency will not issue, renew or reactivate the license without it. California's Contractors State License Board states the requirement and the amount in one line: "The bond must be in the amount of $25,000." [1] Washington requires a continuous contractor surety bond as a condition of registration [4]. Oregon fixes the amount by license endorsement in administrative rule [3].
A license bond is also not a bid bond, a performance bond or a payment bond. Those are written for one project and one owner, and they guarantee that you will sign the contract you bid, finish the work, or pay the people below you on that job. A license bond is not attached to a project at all. It sits behind your license for as long as you hold the license.
Who it protects, and who repays
The direction of this guarantee is the part that gets read backwards. The bond is not there for you.
CSLB names the beneficiaries directly: "The bond is filed for the benefit of consumers who may be damaged as a result of defective construction or other license law violations, and for the benefit of employees who have not been paid wages that are due to them." [1]
A claim on your license bond is therefore made by someone else, about you: a customer whose work was defective, an employee whose wages went unpaid, or the agency enforcing license law. If the surety investigates and pays, the claimant is made whole up to the bond amount.
Then the second half happens, and it is the half that gets left off sales pages. The surety is not an insurer absorbing a loss it collected premium to absorb. It is a guarantor that advanced money on your behalf, and under the indemnity agreement you signed it comes back to you for what it paid plus its cost of handling the claim. A paid bond claim is a debt you owe.
That is why underwriting a bond looks like underwriting a loan. The surety is not pricing how often contractors damage customers; it is pricing whether you can repay it if it has to pay. Your credit, your financial statements and your claims record are the inputs, which is also why the same bond amount costs two contractors different money.
A bond is not coverage
A license bond does not pay your defense costs, your repair costs, or your loss on your own project. It pays someone damaged by you, and then the surety collects from you. Commercial general liability insurance and workers' compensation are separate products with separate rules. Read your own policy, and confirm what your state and your contract require with the licensing agency.
The bond amount is set by the state, the premium is not
Two different numbers both get called "the bond cost", and they are not related the way people assume.
The bond amount, or penal sum, is the ceiling on what the surety can be called on to pay across claims on that bond. It is set by statute or administrative rule, not by the surety, not by you, and not by the size of your jobs. California sets $25,000 for the contractor's bond [1]. Washington sets $30,000 for general contractors and $15,000 for specialty contractors [4]. Oregon sets a separate figure for each license endorsement [3].
The premium is what you pay the surety, per year, to keep that bond in force. It is a percentage of the bond amount, and that percentage is underwritten. No state bond statute sets it.
annual premium = bond amount × premium rate
Two things follow. Shopping for a smaller bond amount is not an option, because the state fixed it. And the only term you can move is the rate, which moves on credit and history rather than on anything about the work.
Three states, three shapes
Three states with verified records show three different structures. Read them as three examples of how a rule can be built, not as a national pattern.
California requires one bond for the license and can require two more. The contractor's bond is $25,000 [1]. A Bond of Qualifying Individual, also $25,000, is required "if the license is qualified by a Responsible Managing Employee (RME)", and also where the license is qualified by a Responsible Managing Officer "who does not own at least 10% of the voting stock of the corporation" [1]. A limited liability company files another: "A $100,000 surety bond (in addition to the $25,000 contractor bond) is required for the issuance of both active and inactive licenses" [2], and CSLB describes that bond as being for the benefit of workers damaged by the LLC's failure to pay wages, interest on wages, fringe benefits or other contributions [2].
Oregon sets the amount by what you are endorsed to do. OAR 812-003-0171 lists each endorsement with its own figure, among them Residential General Contractor at $25,000 and Commercial General Contractor Level 1 at $80,000 [3]. The Construction Contractors Board states how the schedule moved: "The bond amount will increase by $5,000 for each CCB endorsement type." [5] Change what you are endorsed for and the required bond changes with it.
Washington splits on scope of work rather than on residential versus commercial. Registration requires a continuous contractor surety bond "in the amount of: $30,000 for general contractors. $15,000 for specialty contractors." [4]
| State | Bond | Amount |
|---|---|---|
| California | Contractor's bond | $25,000 |
| California | Bond of Qualifying Individual | $25,000 |
| California | LLC bond, in addition | $100,000 |
| Oregon | Residential General Contractor | $25,000 |
| Oregon | Commercial General Contractor Level 1 | $80,000 |
| Washington | General contractor | $30,000 |
| Washington | Specialty contractor | $15,000 |
What it costs
The premium is not set by statute or rule, and the agency pages that fix the bond amount state no price. What can be published honestly is what surety agencies themselves put in writing about their own rates. Our contractor license bond cost calculator compiles ranges published by eight surety agencies and groups them by credit tier.
Those published ranges, as a percentage of the bond amount per year, are 0.4% to 3% for excellent credit, 0.4% to 5% for good credit, 0.9% to 15% for fair credit, and 2% to 15% for poor credit [6].
| Credit tier | Published annual rate |
|---|---|
| Excellent | 0.4%–3% |
| Good | 0.4%–5% |
| Fair | 0.9%–15% |
| Poor | 2%–15% |
Three cautions about that table. It records what agencies publish, not what any surety will charge you. The ranges overlap heavily, because published guidance is written to cover many states and many bond amounts at once. And the rate is only half the arithmetic: the bond amount multiplies it.
As an example using the amounts above, a 0.4% rate on a $25,000 bond is $100 for the year and a 3% rate on the same bond is $750. Hold the rate still and change the bond instead: 2% of a $25,000 bond is $500, while 2% of an $80,000 bond is $1,600. The rate you are offered and the amount your state requires are two separate facts, and you need both before any figure means anything.
Your own number comes from a surety or an agent who has looked at your credit and your financials. Get it in writing, and check what the quote covers: the bond term, whether it renews annually, and what the agency filing costs.
Where this varies by state
Bond requirements are written state by state, and the three above are not a template for the rest. Some states license and bond contractors at the state level. Some leave licensing to cities or counties. Some require a bond only for particular trades, particular license classes, or particular dollar thresholds of work. The bond amount, who may claim on it, how long it stays open after a job, and whether a cash deposit or letter of credit can be filed instead are all set locally. Oregon's rule, for instance, is titled for the bond, letter of credit or cash deposit together [3].
Framing & Figures publishes verified per-state contractor license bond records, with the statute or rule and the date each one was checked. The state records index lives in our state data section as the contractor license bonds dataset. The amounts on this page are the California, Oregon and Washington records from it.
Before you file anything, confirm the current amount and form with your own state's licensing agency. An amount that was right when you last renewed may have moved: Oregon's schedule did, and the increase is published on the agency's own page [5].
Frequently asked questions
What is a contractor bond?
A contractor license bond is a three-party guarantee filed with a state licensing agency as a condition of holding a contractor license. You are the principal, a surety company issues the bond, and the state is the obligee. It guarantees your conduct to the state; it is not insurance for you.
How does a contractor bond work?
Someone damaged by your work (a consumer, an unpaid employee, or the agency enforcing license law) files a claim with the surety. The surety investigates and pays valid claims up to the bond amount. It then recovers what it paid from you under the indemnity agreement you signed.
What is a contractor surety bond?
The same instrument, named for the company that issues it. The surety is the guarantor; the bond is its written guarantee to the obligee. Contract bonds such as bid, performance and payment bonds work the same three-party way but are written for one project rather than for your license.
Contractor bond requirements
The bond amount, the license classes it applies to, and the form you file are set by your state. California's contractor's bond is $25,000. Washington requires $30,000 for general contractors and $15,000 for specialty contractors. Oregon sets a separate amount for each endorsement. Confirm your own requirement with the licensing agency.
