California Performance BondFor Public Works & Commercial GCs

Because they secure completely different things. The license bond you posted to activate your CSLB license is a standing consumer-protection bond fixed at $25,000; it never changes with the size of your work. A performance bond is contract-specific and runs at 100% of the contract price — it guarantees the owner that this particular project gets finished on terms. The moment a commercial developer or public agency awards you bonded work, the $25,000 license bond stops being the relevant number; the full contract value does. If you are still operating purely off the license bond, you have not yet been underwritten for bonding capacity, which is the gate to public and commercial GC work. Most California commercial GCs hold both at once, frequently through different carriers, because they answer to different parties — the homeowner versus the project owner.

Performance bonds in California run at 100% of the contract price; the 50%/100% figures people quote are PAYMENT bond percentages, not performance bond percentages, and they are routinely conflated online. Here is the accurate breakdown: on state contracts under the State Contract Act, Public Contract Code 10221 requires separate performance AND payment bonds, and PCC 10222 sets the payment bond at not less than 50% of the contract price. On local agency contracts (city, county, school district), the statutory payment bond under Civil Code 9554 is not less than 100% of the contract price, triggered on contracts over $25,000 by Civil Code 9550. The performance bond itself is set at 100% by the awarding agency and the contract documents in both cases. So budget your premium against the full contract value for the performance bond, plus a separate payment bond at the statutory percentage above.

Bonding capacity is underwritten off your balance sheet, not your license. Under roughly $500,000 in contract value a surety usually works from the application and contract documents alone. From $500,000 to about $2 million, expect to provide company financial statements, a personal financial statement on the owners, and bank references. Above $2 million, sureties want CPA-prepared (reviewed or audited) year-end financials, an up-to-date work-in-progress schedule showing your open jobs and gross profit fade, and details on your bank line of credit. The two numbers that move a commercial GC the most are working capital and net worth — carriers commonly set a single-job limit around 10x working capital and an aggregate program limit around 10x to 20x. Clean, accountant-prepared financials are what unlock the jump from small jobs to the larger bonded contracts most California GCs are aiming for.

SB 61, effective January 1, 2026, caps retention on California private works at 5% of each progress payment. The exception that matters for bonding runs downstream: if a contractor or subcontractor gives advance written notice before bid time that bonds are required, and the downstream party fails to furnish them, the retaining party may withhold up to 10%. That exception does not apply to owners retaining from direct contractors — owners are capped at 5% regardless. The practical effect is that commercial GCs now have a financial incentive to require performance bonds from their subs: it lets them retain 10% rather than 5% from any sub who does not bond. So even off public works, more California subcontractors are seeing first-time performance and payment bond requirements appear in private subcontracts. If that is you, SB 61 is almost certainly the driver, and the premium belongs in your bid.

Yes — it is built for exactly the contractor stepping up from license-bond-only work into bonded contracts. The SBA guarantees a participating surety against most of its loss on bid, performance, payment, and maintenance bonds for contracts up to $9 million ($14 million on certain federal contracts), which makes carriers willing to extend capacity to GCs with thinner balance sheets or limited bonded track records. The guarantee tier is 90% on contracts up to $100,000 and for priority groups (disadvantaged, HUBZone, 8(a), and veteran-owned firms), and 80% on other contracts. In FY2025 the program backed a record $10.6 billion in guarantees nationally, supporting more than 2,200 small businesses. Apply through an SBA-approved agent in parallel with the standard bonding submission, so it does not add meaningful time to your file.

Code of Civil Procedure Section 995.311 requires bonds on public works contracts to be executed by an admitted surety insurer, and the awarding body will reject a bond from a non-admitted carrier. Verify status yourself through the California Department of Insurance (CDI) Company Profile database — search by company name or NAIC number and confirm the carrier holds a Certificate of Authority for surety lines. We place California performance bonds only with CDI-admitted, U.S. Treasury-listed carriers, but you can and should independently confirm admitted status before the bond is filed with the agency.
