Contractor and Surety Bonds
Contractor and surety bonds back a promise you make to someone else: to the state, to a customer or to the owner of a project. This page walks through the bonds California’s contractors board asks for, the bonds that come with larger jobs, and why a bond works differently from an insurance policy.
What a surety bond is, and why it is not insurance
Every surety bond involves three parties. You, the principal, take on an obligation. The obligee, such as a state board, a city or a project owner, is the party the bond protects. The surety is the company that stands behind your promise, and if you fall short and a valid claim is made, the surety can step in and pay the obligee.
The surprise for many first-time buyers is what happens next. Before issuing a bond, the surety has you sign an indemnity agreement, and under it you repay the surety for whatever it pays out on a claim, along with its costs. Travelers says plainly that a surety bond is not an insurance product for this reason. A policy is designed to absorb losses, while a bond works more like credit, and the surety expects to be made whole. For a corporation or LLC, sureties often ask the owners to sign personally as indemnitors too.
The bonds California’s contractors board requires
CSLB requires a contractor bond on file before it will issue, renew or reactivate an active contractor record. The board describes the bond as protection for consumers harmed by defective construction or other violations of contractor law, and for employees owed unpaid wages. The business name and your CSLB number on the bond must match the board’s records exactly, and the board must receive the bond within 90 days of its effective date.
When the person who qualifies the business is a responsible managing employee, or a responsible managing officer who owns less than ten percent of the company’s voting stock, CSLB also asks for a bond of qualifying individual. An officer with a larger ownership stake files a statement instead, and a business with more than one qualifier needs a bond for each person who falls in those groups. The qualifier’s name on that bond must match CSLB’s records as well.
A contractor organized as a limited liability company carries one more: the LLC employee/worker bond. CSLB says it protects employees and workers harmed by the LLC’s failure to pay wages, interest on wages or fringe benefits, and an active LLC record needs it on top of the contractor bond. LLC contractors must also keep a liability insurance policy on file with the board, a separate requirement from either bond. CSLB accepts a cashier’s check for the full amount in place of a bond, which ties up working cash instead of drawing on a surety.
Bid, performance and payment bonds
Contract bonds come into play when you pursue larger jobs. A bid bond accompanies your proposal and assures the owner that, if your bid is chosen, you will sign the contract and provide the bonds it calls for. A performance bond backs your promise to complete the work as the contract describes. A payment bond backs your promise to pay the subcontractors, laborers and suppliers on the project, and it gives those unpaid parties a claim against the bond.
Public agencies are the most frequent source of these requirements, and the SBA notes that many public and private contracts call for surety bonds. Developers, lenders and owners of larger commercial projects ask for them too, and a general contractor often passes performance and payment bonds down to its own subcontractors. The SBA also runs a program that backs contract bonds for small businesses that meet its size and contract criteria.
City, permit and other commercial bonds
Not every bond ties to a construction contract. Cities and counties ask for permit bonds before some work in the public right-of-way, such as encroachment or street-opening permits, and other public bodies set bond requirements for particular trades and activities. The Surety & Fidelity Association of America groups these with court, fiduciary and public official bonds as commercial bonds, separate from contract bonds.
Read the permit conditions for the bond form, the amount and who must be named as obligee, and note how long the bond has to stay in force after the work ends. A city bond is easy to overlook when you are focused on the CSLB record, so keep a short calendar of every bond’s renewal date alongside your insurance renewals.
Who asks about contractor and surety bonds
Every trade working under a CSLB number meets the contractor bond: general builders, electricians, plumbers, roofers, HVAC and painting contractors among them. Our page on insurance for contractors covers the liability and vehicle questions those businesses raise alongside the bond. Many handymen start with small repairs and meet a bond requirement once their jobs grow past the limit California sets for work without a CSLB number.
Landscaping businesses that install irrigation, hardscape or planting under a CSLB classification carry the same bond, and those bidding on parks, school grounds or municipal maintenance often see bid and performance bonds as well. Cleaning and facility service companies bidding on public building contracts sometimes find a performance bond in the solicitation, which is a different instrument from the client-property bond described on our crime bonds page.
What a surety looks at, and how bonds sit beside insurance
For the CSLB bonds, underwriting is usually light: the business name and entity type, your CSLB number or application, the qualifier’s details and the owners’ personal credit. Contract bonds are underwritten more like a loan. Expect to share business and personal financial statements, a schedule of work in progress and completed projects, bank references, and the contract and bond forms for the job. Sureties often set a single-job limit and a total program limit, so start that conversation well before a bid deadline; the quote checklist helps organize the business details.
Bonds and insurance answer different questions, and contracts usually ask for both. A bond backs your obligation to the obligee. General liability addresses injury and property damage to others from your work, and workers’ compensation, which California requires for every employer with employees, addresses staff hurt on the job. When a contract lists bonds, limits and endorsements together, send the whole requirement page with your request, and read our guide to insurance requirements in client contracts for how those clauses are usually written.
How are contractor and surety bonds priced?
A surety bond is priced as a yearly percentage of the bond amount, and the usual starting point for a California contractor is the $25,000 CSLB contractor bond. As of 2026, bond providers publish starting prices around $193 a year for that bond and rates of about 1% to 3.5% of the bond amount for owners with strong personal credit, roughly $250 to $875 a year. Those figures describe small contractors with good credit buying the bonds the state requires. A newer company, an owner with weak credit or a contractor needing large job bonds commonly pays well above them; the wider published range reaches about 15% of the bond amount. These are bond providers’ published rates, not a Mithril1 quote.
Every bond scales with its amount. A $25,000 contractor bond at 1% costs $25,000 × 1% = $250, at 3.5% about $875, and at 15% about $3,750. An LLC adds a $100,000 employee/worker bond, which bond providers list from about $2,000 a year, and the bond of qualifying individual is another $25,000. Performance and payment bonds apply the same logic to the contract: one surety’s published rate for good-credit contractors on bonds under $450,000 is 1% to 3% of the bond amount, so a $250,000 performance bond comes to about $2,500 to $7,500.
Your rate moves up with lower personal credit, thin or unaudited financial statements, little time in the trade, past bond claims or CSLB complaints, a riskier line of work and contract bonds that stretch your bonding capacity. It moves down with strong owner credit, clean CPA-prepared financials, steady work in progress, a long claim-free record and, for some state bonds, a multi-year term.

A few useful answers
Common questions
How is a contractor bond different from contractor insurance?
The contractor bond backs your obligations to consumers and workers under California contractor law, and you repay the surety for what it pays on a claim. General liability and workers’ compensation are separate purchases with their own purposes, and CSLB asks for the bond on top of whatever insurance you carry.
Who needs a bond of qualifying individual as well as the contractor bond?
CSLB asks for one when a responsible managing employee qualifies the business, or when a responsible managing officer owns less than ten percent of the voting stock. Each qualifier in those groups needs a separate bond.
What does the CSLB LLC employee/worker bond protect?
CSLB describes it as protection for employees and workers harmed by an LLC contractor’s failure to pay wages, interest on wages or fringe benefits. It is separate from the contractor bond, and an active LLC record needs both.
What happens after a surety pays a claim on a contractor or surety bond?
Under the indemnity agreement you signed, you reimburse the surety for the amount paid and its costs. An open claim can also make the next bond harder to place, so deal with customer complaints early.
When does a job call for bid, performance and payment surety bonds?
When the contract or bid documents say so. Public works solicitations commonly list them, and private owners, lenders and general contractors add them to larger contracts. Read the bond section before you price the job.
Can I give CSLB a cashier’s check instead of a contractor bond?
CSLB accepts a cashier’s check for the required amount as an alternative to a surety bond. Weigh tying up that cash against the premium and indemnity terms a surety offers before choosing.
