Last Updated: February 2026 by the ZipBonds Team
If you’re a contractor working on public or large commercial projects in California, construction bonds are often part of the job. California projects commonly require:
- Bid bonds during the bidding phase
- Performance bonds once a contract is awarded
- Payment bonds to protect subcontractors and suppliers
These requirements appear most often on public works projects, but many private developers across California also require bonding to reduce risk.
ZipBonds helps contractors across California secure fast approvals and competitive rates for construction bonds of all sizes.
Quick Summary: California Construction Bond Requirements
- Public works projects often require performance and payment bonds.
- Bid bonds are common during competitive bidding.
- Private developers may also require bonded contractors.
- Requirements vary by project, agency, and location.
- California public works bonding requirements are primarily governed by the Civil Code and Public Contract Code.
How Construction Bond Requirements Work in California
Construction bonds follow national surety principles, but California statutes and public agencies determine when bonds are required and in what amounts.
This page focuses on how those bonds are used specifically in California construction projects. With the new 5% retention cap on private projects in California (Civil Code §8811, effective 2026), owners may lean more on bonds. ZipBonds specializes in fast approvals.
See our Construction Bonds Guide for basics. You can also explore our in-depth resources on Bid Bonds, Performance Bonds, and Payment Bonds.
California Statutory Bond Requirements (Public Works)
California public construction bonding is governed primarily by:
- California Public Contract Code
- California Civil Code
Payment Bonds
Payment bonds are required on California public works contracts exceeding $25,000 when a direct contract is awarded by a public entity. (Civil Code § 9554)
Performance Bonds
Performance bonds are typically required on California public works contracts, often written for 100% of the contract amount. (Public Contract Code §§ 7103, 10221)
Bid Bonds/Security
Public agencies frequently require bid security equal to 10% of the bid amount. (Public Contract Code § 10167)
These requirements apply to:
- State agencies
- Counties
- Cities and municipalities
- School districts
- Public authorities
What are construction bonds?
Construction bonds are three-party financial guarantees involving:
- The contractor (principal)
- The project owner or public entity (obligee)
- The surety company that backs the contractor’s obligations
These bonds protect project owners and ensure compliance with contract obligations. For deeper technical details, visit our main Construction Bonds resource.
Types of Construction Bonds Used in California
California follows national bonding principles but has specific statutory requirements governing payment bonds, bid security, and public works protections.
1. Bid Bonds
Bid bonds are commonly required on California public works projects during competitive bidding. Public agencies typically require bid security equal to 10% of the bid amount.
- National Standard: A percentage of the bid.
- California Context: Frequently required on state, county, school district, and municipal bids.
2. Performance Bonds
Performance bonds guarantee that the contractor will complete the project according to the contract. If the contractor defaults, the surety may step in to arrange completion.
- National Standard: Often issued for the full contract amount
- California Context: Standard on most public works and many larger private projects, typically for 100% of the contract amount.
3. Payment Bonds
Payment bonds protect subcontractors, laborers, and suppliers. On public projects, this is especially important because lien rights differ from private work.
- National Standard: Typically paired with performance bonds.
- California Context: Frequently required together with performance bonds.
4. Contractor License Bonds
In addition to bid, performance, and payment bonds tied to specific construction contracts, many contractors in California will also encounter contractor license bond requirements. A contractor license bond is different from a construction project bond. Instead of guaranteeing performance on a single job, a license bond supports compliance with licensing laws and regulations. Certain cities, counties, or specialty licensing authorities may require this type of bond as part of the contractor licensing or registration process. Key difference:
- Construction project bonds (bid, performance, payment) are tied to a specific construction contract.
- License bonds are tied to a contractor’s legal authorization to operate within a jurisdiction.
In California, contractors must carry a $25,000 license bond to uphold the California Contractors License Law. Learn more about California contractor license bond requirements.
| Bond Type | Purpose | National Standard | California Application | |
|---|---|---|---|---|
| Bid Bond | Ensures contractor enters contract | 5-10% of bid | Typically 10% of bid on public works (Public Contract Code §10167) | |
| Performance Bond | Guarantees project completion | Often 100% of contract amount | 100% on many public projects (Public Contract Code §§7103, 10221) | |
| Payment Bond | Protects subs & suppliers | Paired with performance | Required on many public jobs >$25,000, 100% (Civil Code §9554) | |
| Contractor License Bond | Guarantees compliance with licensing rules | Required by some local jurisdictions and trades | $25,000 required for CSLB license (CSLB requirements) |
When are construction bonds required in California?
Public Works Projects
California public construction projects frequently require payment bonds (> $25,000 per Civil Code §9554) and performance bonds (typically 100% per relevant Public Contract Code sections).
These requirements typically apply once a contract is awarded, not at the bid stage. Specific requirements appear in state, county, school district, and municipal contracts.
Municipal & Local Projects
Cities and local public entities include bonding requirements in their bid documents. Each project’s specifications outline the exact bond amounts and forms.
Private Commercial Projects
Private developers often require bonded contractors for large or complex projects to reduce financial risk.
Major 2026 Update: Starting January 1, 2026, California caps retention at 5% on most private works contracts (Civil Code §8811, via SB 61). This limits withheld progress payments/total retention to 5% (with exceptions, e.g., if bonds are required but not provided, or certain low-rise residential projects). Public works retention rules differ from private works and are not affected by this change.
Owners may now require stronger bonding to offset reduced retention. ZipBonds can help secure competitive rates.
Licensing vs. Project Bonds
Contractor license bonds in California are separate from construction project bonds. License bonds relate to regulatory compliance, while bid, performance, and payment bonds apply to specific construction contracts.
When Construction Bonds May NOT Be Required
- Private projects where the owner waives bonding
- Small public contracts below statutory thresholds
- Certain negotiated or emergency contracts
- Design-build or alternative delivery models
California Construction Bonds vs Federal Miller Act Bonds
California public works follow Civil Code and Public Contract Code requirements, while federal projects follow the Miller Act. Thresholds and claim procedures differ.
Cost of Construction Surety Bonds in California
Bond premiums in California follow national underwriting standards. Many qualified contractors pay a small percentage of the bond amount, as low as 1%, while higher-risk applicants may pay more depending on credit, experience, and financial strength. California may see slightly greater scrutiny of large public projects, but rates remain aligned with national standards.
Rates depend on:
- Credit history
- Experience with similar projects
- Financial strength
- Contract size

Surety underwriters review:

- Confusing bonds with insurance
- Not understanding indemnity obligations
Planning helps prevent delays.
Bond Claims: What happens if there’s a problem?
If a contractor fails to meet contract terms, the project owner may file a claim against the bond. The surety investigates and may pay costs to resolve the issue, but the contractor is typically responsible for reimbursing the surety.
On California public works, payment bond claimants must follow strict notice and timing requirements under the Civil Code. Missing deadlines can invalidate a claim. Private project bond and lien claim procedures follow different rules and timelines.
Pro Tip: Proper project management helps minimize risk.
