California Performance Bond50% State | 100% Local
California is the only state that splits its public works bonding into two separate statutory frameworks with different bond amounts. State agency contracts under the State Contract Act (PCC 10222) require performance bonds at 50% of the contract price. Local agency contracts -- cities, counties, school districts -- under Civil Code 9554 require the full 100%. Every competitor page gets this wrong by citing only one statute. Understanding which framework applies to your project determines your bond amount, your premium, and the claims process if something goes sideways. Need to understand the basics first? Start with our guide to how surety bonds work.
Two Statutes, Two Bond Amounts: The California Split
Search for “California performance bond” and you will find dozens of pages claiming bonds are always 100% of the contract price. That is only half right. California operates under two entirely separate statutory frameworks for public works bonding, and the one that applies to your project depends on who awarded the contract -- not what you are building.
The State Contract Act (Public Contract Code Sections 10221-10232) governs contracts awarded by state agencies: Caltrans, the Department of General Services, UC and CSU systems, and other state entities. Under PCC 10222, performance bonds on state contracts are set at 50% of the contract price. Civil Code Sections 9550-9566 govern contracts awarded by local agencies -- cities, counties, school districts, water districts, and special districts. Under Civil Code 9554, the performance bond must equal 100% of the contract price. The distinction matters because it directly affects your bond premium. A $2 million Caltrans project requires a $1 million bond; the same project for a county requires $2 million. That difference can mean thousands in annual premium.
California Performance Bond Requirements: State vs. Local
Based on a $2,000,000 contract example
| Factor | State Agency Projects | Local Agency Projects |
|---|---|---|
| Governing Law | Public Contract Code 10221-10232 | Civil Code 9550-9566 |
| Performance Bond Amount | 50% of contract price | 100% of contract price |
| Example on $2M Contract | $1,000,000 bond | $2,000,000 bond |
| Est. Premium (good credit) | $5,000 - $15,000 | $10,000 - $30,000 |
| Payment Bond Threshold | $25,000+ (PCC 7103) | $25,000+ (Civil Code 9550) |
| Separate Payment Bond? | Yes, required (PCC 10221) | Yes, required (Civil Code 9554) |
| Obligee | State agency (e.g., Caltrans, DGS) | City, county, school district, etc. |
Payment bonds are required in addition to performance bonds when the contract exceeds $25,000. Both statutes require separate bonds.

Official California Requirements
"The performance bond shall be in the sum of not less than 50 percent of the contract price... Every original contractor on a public work shall, before commencing work under the contract, give a bond to secure the performance of the contract, in an amount not less than 100 percent of the total amount payable."California Legislature • PCC 10222 (state) & Civil Code 9554 (local)
SB 61 and the New Economics of Private Project Bonds
Effective January 1, 2026, SB 61 caps retention on California private works at 5% of each progress payment. But here is the exception driving new demand for performance bonds: when a contractor or subcontractor gives advance written notice that bonds are required and the downstream party fails to furnish them, the retaining party may withhold up to 10%.
This downstream protection mechanism is reshaping how general contractors manage subcontractor risk. A GC who requires performance bonds from subs — and gives proper written notice before bid time — gains the right to retain 10% from any sub who fails to provide the bond. The result: more GCs are requiring performance bonds in subcontracts, and more subs are being asked to furnish them for the first time. If you are a subcontractor receiving a new bond requirement on private work, SB 61 is almost certainly the reason. Factor the bond premium into your bid accordingly.
Sub Furnishes Bond
Sub Fails to Furnish Bond
SB 61 interaction: The 5% retention cap applies to private works contracts entered on or after January 1, 2026. The 10% exception applies only downstream — when a contractor or subcontractor gave advance written notice before bid time requiring bonds, and the subcontractor failed to furnish them. The exception does not apply to owners retaining from direct contractors.
California Performance Bond Cost by Contract Size
Performance bond premiums are not a flat percentage. They scale with contract size, with higher rates on the first dollar and lower marginal rates as the contract grows. A $200,000 project might cost 3% ($6,000), while a $5 million project might average 1.5% ($75,000). Your credit score, contractor experience, financial statements, and the project's risk profile all affect the final rate. For a deeper breakdown, see our performance bond cost guide or our general surety bond pricing page.

The Full California Public Works Compliance Stack
A performance bond is one piece. California public works contractors must satisfy several independent requirements before starting work. Missing any one of them can disqualify your bid or halt your project.
Performance Bond
50% of contract price for state agency projects (PCC 10222) or 100% for local agency projects (Civil Code 9554). Must be from a CDI-admitted surety insurer.
Payment Bond
Required on contracts over $25,000 under both PCC 7103 (state) and Civil Code 9550 (local). Protects subcontractors and material suppliers. Filed separately from the performance bond.
DIR Registration
Department of Industrial Relations contractor registration ($400/year). Must be active before bidding. DIR number must appear on bid documents. Applies to all tiers of subcontractors.
CSLB License + Bond
Active Contractors State License Board license in the appropriate classification. Includes the separate $25,000 CSLB license bond (SB 607, effective 2023). This is not a performance bond.
Prevailing Wage Compliance
All California public works require prevailing wage rates. Certified payroll reports must be submitted to the Labor Commissioner. Non-compliance can trigger stop notices and bond claims.
Bid Bond
Typically 10% of bid amount on formally bid projects. Guarantees you will enter the contract if awarded. Forfeited if you withdraw after bid opening. Required on projects over $220,000 (AB 2192 threshold).
Need the bid bond and payment bond alongside your performance bond? We can package all three together. For a walkthrough of the full bonding process, see our step-by-step guide.
CSLB License Bond vs. Performance Bond: Not the Same Thing
SB 607 raised the CSLB contractor license bond from $15,000 to $25,000 in 2025. Many contractors confuse this with a performance bond. They serve different purposes, protect different parties, and are governed by different statutes.
CSLB License Bond ($25,000)
- Secures your CSLB contractor license
- Fixed $25,000 amount (SB 607)
- Protects consumers against license violations
- Remains in force for life of license
- Required for all licensed contractors
Project Performance Bond
- Tied to a specific contract and project
- 50% or 100% of contract price
- Guarantees project completion per contract terms
- Expires when project is completed and accepted
- Required on public works; increasing on private
Caltrans Encroachment Permits: A Separate Bond Category
If your work encroaches on the state highway right-of-way -- utility crossings, drainage connections, landscaping within the highway corridor -- Caltrans requires an encroachment permittee performance bond under Streets and Highways Code Section 677. This bond is set at 50% of the estimated project cost, separate from any contract performance bond required on the underlying project.
The encroachment bond guarantees you will restore the highway right-of-way to its original condition after your work is complete. It runs until Caltrans inspects and approves the restoration. Contractors frequently need both an encroachment bond for the highway work and a standard performance bond for the broader project -- they are issued independently, sometimes by different surety carriers.
SBA Surety Bond Guarantee: Your Path to Larger Projects
The SBA Surety Bond Guarantee Program exists specifically for contractors who cannot yet qualify for conventional bonding. The SBA guarantees 90% of the surety's loss on bonds up to $9 million ($14 million for certain federal contracts), making carriers far more willing to underwrite emerging contractors with limited financial history. In FY2025, the program backed a record $10.6 billion in bond guarantees nationally.
The SBA charges approximately 0.6% of the contract price as a guarantee fee -- this is in addition to the surety's premium, but it is often the difference between getting bonded and not. The application runs through an SBA-approved surety bond agent (we are one) in parallel with the standard bonding application, so it adds minimal time. California contractors pursuing their first public works projects or stepping up to larger contract sizes should ask about SBA backing.

California Performance Bond Questions
Specific to California statutes, recent legislation, and compliance requirements
Why does my state agency contract only require a 50% performance bond?
California has two separate bonding statutes depending on which government entity awards the contract. Under Public Contract Code Section 10222, state agency contracts (Caltrans, DGS, etc.) require performance bonds at 50% of the contract price. Local agency contracts -- cities, counties, school districts, and special districts -- fall under Civil Code Section 9554, which requires 100% of the contract price. This distinction exists because the State Contract Act (PCC 10221-10232) was enacted separately from the local public works bonding framework. If your contract is with a state agency, confirm the obligee and cite PCC 10222 when applying for your bond. If it is with a city, county, or school district, expect the full 100%.
How does the new SB 61 retention cap affect performance bonds on private projects?
SB 61, effective January 1, 2026, caps retention on private works at 5% of each progress payment. The 10% exception applies 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%. This exception does not apply to owners retaining from direct contractors — owners are capped at 5% regardless of bonding status. The practical result is that general contractors are increasingly requiring performance bonds from subcontractors to manage risk under the new retention limits. If you are a subcontractor on private work and receive a new bond requirement, SB 61 is likely the driver.
Do I need DIR registration in addition to a performance bond for California public works?
Yes. Since 2014, every contractor and subcontractor bidding or working on California public works projects must register with the Department of Industrial Relations (DIR) and pay the $400 annual registration fee. DIR registration is separate from your CSLB license and separate from bonding. A valid DIR registration number must appear on your bid submission -- the awarding body will reject bids from unregistered contractors regardless of bonding status. Your performance bond, payment bond, and DIR registration are three independent compliance steps that must all be current before you start work on any public works project in California.
What is the difference between my CSLB license bond and a project performance bond?
The CSLB contractor license bond (currently $25,000 under SB 607, effective 2023) is a standing bond that secures your contractor license itself. It covers consumer claims related to your license status and stays in force as long as you hold a CSLB license. A project performance bond, by contrast, is tied to a specific contract and guarantees you will complete that particular project according to contract terms. They protect different parties for different purposes. The license bond protects consumers who hire you; the performance bond protects the project owner who awarded you a contract. Most public works contractors in California carry both simultaneously -- but they are issued separately, often by different surety carriers, and serve completely different legal functions.
Can the SBA Surety Bond Guarantee Program help me get a California performance bond?
Yes. The SBA Surety Bond Guarantee Program guarantees 90% of the surety carrier's loss on bonds up to $9 million (up to $14 million for certain federal contracts). In FY2025, the program backed a record $10.6 billion in bond guarantees nationally. The SBA charges a fee of approximately 0.6% of the contract price. This program is particularly valuable for small and emerging contractors who may not yet qualify for conventional bonding -- it reduces the surety's risk, which makes carriers more willing to underwrite contractors with limited track records or smaller balance sheets. Apply through an SBA-approved surety bond agent. The process runs in parallel with the standard bonding application, so it does not add significant time.
How do I verify that my surety company is admitted to write bonds in California?
California Code of Civil Procedure Section 995.120 requires all surety bonds on public works projects to be executed by an admitted surety insurer. The California Department of Insurance (CDI) maintains a searchable Company Profile database where you can verify any surety carrier's active status. Search by company name or NAIC number and confirm the carrier holds a "Certificate of Authority" for surety lines. Bonds from non-admitted carriers will be rejected by the awarding agency. Working with an established surety bond agency like BuySuretyBonds.com ensures your bond is written by a CDI-admitted, Treasury-listed carrier -- but you can always independently verify status through the CDI website before your bond is filed.
