Surety bonds are a form of credit that guarantees a contractor's performance of contractual obligations. CSLB requires license bonds, prime contracts require bid and performance bonds, and public projects require payment bonds. We help contractors understand bonding requirements and access surety markets that conventional lenders have abandoned.
Surety bonds are a form of credit — not insurance. A surety bond is a three-party agreement: the contractor (principal) is obligated to the surety (bonding company), and the surety is obligated to the obligee (the party requiring the bond). If the contractor fails to perform, the surety fulfills the obligation and recovers from the contractor through indemnity agreements.
Every CSLB licensed contractor must post a license bond with the state. The bond amount is $25,000 for most classifications (or $12,500 for certain limited liability categories). This bond guarantees that the contractor will comply with CSLB regulations and respond to consumer complaints. The license bond remains active as long as the contractor holds the license.
The license bond is a non-negotiable requirement for CSLB licensure. A contractor cannot hold an active license without an active license bond. If the bond is cancelled, the CSLB will automatically suspend the license within days.
When a contractor submits a bid on a project — whether private or public — the owner or general contractor may require a bid bond guaranteeing that the contractor will enter into the contract at the bid price if awarded the project. Bid bonds typically guarantee 5-10% of the bid amount. If a contractor bids $100,000 and is awarded the project but refuses to enter into the contract, the bid bond pays the obligee up to the bond amount (typically $5,000-$10,000).
Bid bonds are relatively inexpensive (typically 1-2% of the bond amount annually) because the obligee's recovery is limited to the bond amount, not the full cost of the non-performance.
A performance bond guarantees that a contractor will complete the work per contract specifications. If the contractor abandons the project or fails to perform, the surety will either hire another contractor to complete the work or pay damages up to the bond amount. Performance bond guarantees typically equal the full contract price.
Performance bonds are the most expensive type of surety bond because the surety's potential liability equals the full contract amount. For a $1,000,000 contract, the performance bond premium typically runs 1-3% annually ($10,000-$30,000), depending on the contractor's financial condition and track record.
Payment bonds guarantee that a contractor will pay suppliers, subcontractors, and laborers. They're typically required on public works projects and by many prime contractors on private projects. A payment bond protects the supply chain — if a contractor receives payment but doesn't pay their subs and suppliers, the payment bond ensures they get paid.
Payment bonds are often written as a companion to performance bonds at 40-50% of the performance bond premium. A $1,000,000 contract might require both a $1,000,000 performance bond and a $1,000,000 payment bond.
Federal and state law impose mandatory bonding requirements for public projects and government contracts. Understanding these requirements is essential for contractors pursuing public work.
The Miller Act (40 U.S.C. Section 3131-3134) requires contractors on federal construction projects over $150,000 to post payment and performance bonds equal to 100% of the contract price. These bonds protect the federal government and the supply chain — if a contractor fails, the surety completes the work or pays damages.
Miller Act bonds are stricter than state bonding requirements. The surety's liability is tied directly to federal contract law, and the surety's remedies are limited to the bond amount. Federal project delivery is often slower than state projects, which increases surety risk and results in higher premiums.
California's Little Miller Act (Civil Code Section 9100 et seq.) applies to public works projects in California, including state, county, and municipal projects. Unlike the federal Miller Act, California's version applies to projects over a lower threshold and includes prevailing wage requirements.
California requires bid bonds on public projects (typically 5-10% of the bid amount) and performance/payment bonds equal to 100% of the contract price for projects over specified amounts. Additionally, public works projects must comply with Department of Industrial Relations (DIR) prevailing wage requirements, and the surety may be liable if the contractor fails to pay prevailing wage rates.
California's prevailing wage requirements mandate that all workers on public works projects be paid at union-scale rates (typically 1.5-3x market rates for similar work). The surety bond may be held responsible if a contractor fails to pay prevailing wages. Some sureties refuse to bond contractors with poor prevailing wage compliance history.
If you pursue public works projects, maintaining clean prevailing wage compliance is essential to maintaining bond capacity. DIR publishes complaint records that sureties review when evaluating bond applications.
A contractor's ability to obtain surety bonds is determined by financial condition, bonding history, and the surety's assessment of credit risk. Understanding how bond capacity works is essential to growing your contracting business.
A surety will typically cap the total amount of outstanding bonds a contractor can carry based on financial condition. This is called "bond capacity." A contractor with $100,000 in net worth might be approved for $500,000 in total bond capacity, meaning they could carry a $500,000 performance bond OR multiple bonds totaling $500,000.
As a contractor completes bonded projects successfully, their bond capacity increases. Conversely, if a surety pays claims on a failed project, the contractor's bond capacity decreases dramatically or disappears entirely. Building a strong bonding relationship requires consistent financial reporting and successful project completion.
To obtain a surety bond, the contractor must sign an indemnity agreement with the surety promising to repay the surety if it has to pay on the bond. This means if a contractor abandons a project and the surety pays $500,000 to complete it, the contractor is personally liable for repayment. The indemnity is not limited to the bond amount — the contractor's liability extends to the actual cost incurred by the surety.
This makes surety bonding a serious credit obligation. A contractor should not obtain a bond without a clear plan to complete the work and fulfill obligations. The indemnity agreement typically includes a lien on the contractor's assets, giving the surety rights to pursue business assets and personal assets.
For small contractors unable to obtain bonding in the conventional market, the Small Business Administration (SBA) Surety Bond Guarantee Program provides loan guarantees that enable sureties to bond contractors with limited financial history or credit challenges. The SBA guarantees 70-80% of losses on failed bonds, reducing surety risk and expanding bond availability.
SBA surety bonds are available for bid bonds up to $350,000, performance/payment bonds up to $2,000,000 per project (with total outstanding bonds capped at $5,000,000). To qualify, contractors must be small businesses and unable to obtain bonding in the conventional market.
We work with SBA-approved sureties to help contractors access SBA surety programs when conventional bonding is unavailable or prohibitively expensive. The application process requires detailed financial information and a clear project plan, but it can provide access to public works work that would otherwise be impossible.
A surety bond is a form of credit — a three-party agreement where the surety guarantees the principal's (contractor's) obligation to the obligee. If the contractor fails, the surety fulfills the obligation and recovers from the contractor. Insurance indemnifies loss; surety bonds guarantee performance. They're legally and financially distinct.
Every CSLB licensed contractor must maintain a $25,000 license bond (or $12,500 for certain categories) issued to the CSLB. This bond guarantees CSLB regulatory compliance. If the bond is cancelled, the CSLB suspends the license within days. The license bond is non-negotiable for maintaining licensure.
Bid bonds guarantee that if awarded, the contractor will enter the contract at the bid price (typically 5-10% of bid amount). Performance bonds guarantee work completion per contract (typically 1-3% of contract price). Payment bonds guarantee payment of subs and suppliers (typically 40-50% of performance bond). Public works require all three; private work varies.
Bond capacity is the maximum total amount of outstanding bonds a surety will allow. Determined by financial condition and bonding history, it limits your bonding power. As you complete bonded projects successfully, capacity increases. Poor performance decreases or eliminates capacity. Growing bond capacity is essential to scaling a contracting business.
An indemnity agreement is a promise to repay the surety if it has to pay on a bond. If the surety pays $500,000 on a failed project, the contractor is personally liable for repayment — the liability isn't capped at the bond amount. Indemnity agreements typically include liens on business and personal assets.
The federal Miller Act requires performance and payment bonds on federal projects over $150,000. California's Little Miller Act applies to state, county, and municipal projects with similar requirements. Both require 100% bonds and have stricter requirements than private bonding. Prevailing wage compliance is mandatory.
The SBA guarantees 70-80% of losses on surety bonds for small contractors unable to obtain conventional bonding. SBA bonds are available for bid bonds up to $350,000 and performance/payment bonds up to $2,000,000 per project (total $5,000,000). They enable access to public works when conventional bonding isn't available.
