Surety Bond Requirements for Contractors 2026 | State Guide

Q: How much does a contractor license bond cost?

For a creditworthy contractor, annual premium is typically 1–3% of the bond amount. A $25,000 California CSLB bond costs roughly $150–$375 per year. Contractors with poor credit, claims history, or in high-risk trades may pay 5–15% of the bond amount or be required to post collateral.

Most licensing states require contractor license bonds of $5,000–$25,000 as a condition of licensure. California requires $25,000 (CSLB); Washington requires $12,000 (L&I); federal projects over $150,000 require performance and payment bonds under the Miller Act.

Surety Bonds for Contractors: What the Law Requires

A surety bond is a legally binding financial guarantee — not an insurance policy. Where insurance protects the policyholder, a surety bond protects a third party (typically a state licensing board, a project owner, or a consumer) against losses caused by the bonded party's failure to perform, financial default, or fraudulent conduct. For contractors and tradespeople, surety bonds are a licensing prerequisite in most states. Operating without a required bond is a misdemeanor or administrative violation that results in license suspension, fines, and civil liability for unlicensed work.

Bond Type	Who Requires It	Typical Amount	Purpose
Contractor license bond	State licensing board	$5,000–$25,000	Consumer protection; license prerequisite
Performance bond	Project owner / public agency	50%–100% of contract value	Guarantees project completion
Payment bond	Project owner / public agency	50%–100% of contract value	Guarantees payment to subs and suppliers
Fidelity / dishonesty bond	Employer or client	$10,000–$100,000	Covers employee theft
Bid bond	Public project owner	5%–10% of bid amount	Guarantees bidder will execute the contract

Contractor license bonds are the most commonly required bond for trade contractors — electricians, plumbers, roofers, HVAC technicians, general contractors, and more. Performance and payment bonds apply to larger commercial and public projects. Understanding which bonds apply to which work is the starting point for compliance.

Contractor License Bond Requirements by State

License bond requirements vary significantly by state and by trade. Some states require bonds for all contractors; others require them only for specific trades or above certain contract dollar thresholds. The table below covers major states:

State	General Contractor Bond	Specialty Trade Bond	Notes
California	$25,000 (CSLB)	$25,000	Required for CSLB license in all classes
Florida	$5,000–$20,000	$5,000–$10,000	Amount varies by license type
Texas	Varies by city/county	Varies	No statewide license; bond often city-required
Washington	$12,000 general	$6,000 specialty	Required by L&I for registration
Arizona	$0 for ROC license	$0 for ROC license	AZ ROC requires insurance, not a bond
New York	Varies by locality	Varies	NYC has specific bonding by trade
Georgia	$300,000 for GC license	Varies	High threshold for full GC license
Illinois	Varies by municipality	Varies	Chicago has separate trade bonds
Michigan	$1,000–$1,000,000	$1,000–$25,000	Varies by license class significantly

North Carolina	$5,000–$500,000	Varies	Bond increases with license tier

California — CSLB Contractor License Bond

The California Contractors State License Board (CSLB) requires a $25,000 contractor license bond for all licensed contractors as a condition of licensure. The bond is required for initial licensing and must remain in force throughout the license period. California Senate Bill 842 (2021) raised the bond amount from $15,000 to $25,000. The bond protects consumers who suffer losses due to contractor violations of the Contractors State License Law — including defective workmanship, abandonment of a project, and failure to pay workers or suppliers.

Additionally, California contractors with qualifying individuals who do not own at least 10% of the business are required to maintain a $25,000 qualifying individual bond in addition to the standard license bond.

California CSLB also operates a Workers Compensation Coverage Program that requires proof of workers' compensation insurance or a certificate of exemption as part of the license application. The WC requirement is separate from the surety bond requirement.

Washington State — L&I Contractor Registration Bond

Washington State Department of Labor and Industries (L&I) requires:

General contractors: $12,000 surety bond
Specialty contractors: $6,000 surety bond

The bond is required for contractor registration, not just licensing. Even contractors who are not licensed but are registered with L&I must maintain the bond. The bond protects consumers, laborers, and the state against losses from contractor misconduct.

Oregon — CCB Contractor Bond

The Oregon Construction Contractors Board (CCB) requires:

General residential/commercial contractors: $20,000 bond
Specialty contractors: $10,000 bond
Home services companies: $10,000 bond

Oregon's bond protects consumers from contractor misconduct, including failure to complete work or defective construction. The CCB maintains a public bond database that consumers can use to verify a contractor's bonded status before hiring.

Performance and Payment Bonds

Performance and payment bonds are required on public construction projects and increasingly on large private commercial projects. They are distinct from license bonds:

The Miller Act — Federal Projects

The Miller Act (40 U.S.C. § 3131 et seq.) requires prime contractors on federal construction projects valued over $150,000 to obtain both:

A performance bond equal to the contract amount
A payment bond equal to the contract amount

The performance bond guarantees the contractor will complete the project per contract terms. If the contractor defaults, the surety completes the work or compensates the project owner. The payment bond guarantees that subcontractors and material suppliers will be paid — a critical protection because federal projects cannot be subjected to mechanics' liens.

Little Miller Acts — State Projects

All 50 states have enacted "Little Miller Acts" modeled on the federal statute. The threshold and requirements vary:

State	Performance Bond Threshold	Payment Bond Threshold
California	$25,000	$25,000
Texas	$25,000	$25,000
Florida	$200,000	$200,000
New York	$100,000	$100,000
Illinois	$50,000	$50,000

Above the threshold, a prime contractor on a state public project must furnish both bonds before work begins. Subcontractors on bonded public projects can make claims on the payment bond if the general contractor fails to pay.

Private Commercial Projects

Large private commercial projects — office buildings, retail centers, multi-family residential — increasingly require performance and payment bonds from general contractors even though no law mandates it for private work. Project owners and lenders require bonding to protect against contractor default on large construction investments. GCs on bonded private projects may also require subcontractors to provide bonds.

How Surety Bonds Work: Key Mechanics

The Three-Party Relationship

A surety bond involves three parties:

Principal — the contractor or business that purchases the bond and must perform the obligation
Obligee — the party protected by the bond (state licensing board, project owner, consumer)
Surety — the bond company that guarantees the principal will fulfill the obligation

When a valid claim is made against the bond, the surety investigates. If the claim is legitimate, the surety pays the obligee up to the bond amount. Critical distinction from insurance: the surety then seeks reimbursement (subrogation) from the principal. A contractor whose bond pays a consumer claim must repay the surety — a bond is not a risk transfer, it is a credit facility with a guarantee function.

Underwriting — How Bonds Are Priced

Surety companies underwrite bonds based on the principal's financial strength, credit history, and track record. Unlike insurance, where the insurer expects to pay claims as part of the business model, sureties assume they will rarely pay — and they underwrite accordingly.

For contractor license bonds:

Annual premium: typically 1–5% of the bond amount for contractors with good credit
A $25,000 California CSLB bond costs approximately $150–$500 per year for a creditworthy contractor
Contractors with poor credit may face higher rates — sometimes 10–15% of bond amount — or may need to post collateral

Bond Claims

A claim on a contractor license bond is filed by the injured party — usually a consumer, a subcontractor, or a supplier — with the surety company. The surety investigates. If the claim is valid, the surety pays up to the bond penalty (face amount). The contractor (principal) is then obligated to repay the surety.

A license bond claim does not automatically cancel the bond, but a history of claims affects the contractor's ability to renew coverage and may cause the surety to decline renewal.

Surety Bonds vs. General Liability Insurance

Contractors often confuse surety bonds with general liability insurance. They are fundamentally different:

Feature	Surety Bond	General Liability Insurance
Who is protected?	Third parties (clients, state, public)	The contractor (policyholder)
Claims repaid by?	Principal repays the surety	Insurer absorbs the loss
Purpose	Guarantees performance or compliance	Covers accidental damage to third parties
Required for licensing?	Yes, in most states	Yes, in most states
Covers property damage?	Indirectly (for contractor's failures)	Yes, directly
Covers bodily injury?	Indirectly (for contractor's failures)	Yes, directly

Both are typically required for contractor licensing — they serve different purposes and one does not substitute for the other.

Who Needs a Surety Bond: A Profession-by-Profession Guide

General contractors: License bonds required in most licensing states. Performance and payment bonds required on public projects over threshold amounts. Bond amounts vary from $5,000 (some states) to $500,000 (high-tier GC license in some states).

Electricians: License bonds required in most states with electrical licensing. Amounts typically $5,000–$25,000.

Plumbers: License bonds required in states with plumber licensing. Similar range to electricians.

Roofers: License bonds required in states with roofing licensing. Some states have low bond thresholds ($1,000–$5,000) that provide minimal consumer protection.

HVAC contractors: License bond required in states with HVAC contractor licensing. Amounts vary by state licensing tier.

Handymen: Requirements vary. Some states require registration bonds for handymen working above a dollar threshold; others have no separate handyman bond requirement.

Auto dealers: Surety bonds required for dealer licensing in all 50 states. Amounts range from $25,000 to $100,000+ depending on state and dealer type.

Mortgage brokers and originators: Surety bonds required under SAFE Act provisions in most states. Amounts typically $25,000–$75,000.

How to Comply: Getting Bonded as a Contractor

1. Determine the specific bond required for your license

Check your state licensing board's website for the exact bond type, amount, and approved surety list. Bond requirements vary by license classification — a B-General contractor in California has different bond requirements from a C-10 Electrical contractor.

2. Obtain quotes from licensed surety companies

Surety bonds must be issued by a surety company licensed (admitted) to do business in your state. Treasury-listed sureties (Circular 570 list) are required for federal bonded contracts. For state license bonds, any admitted surety company typically qualifies.

3. Submit the bond to the licensing board

The bond must be filed directly with the licensing board, not merely possessed by the contractor. Most state licensing boards require the original bond or a certified copy filed before the license is issued or renewed.

4. Renew annually and avoid lapses

Most contractor license bonds are annual. A lapse in the bond — even by one day — creates a period of unlicensed operation, which may result in license suspension. Set calendar reminders 60–90 days before bond expiration and do not wait until the last minute to renew.

5. Understand your indemnity obligation

Before executing a bond, read the indemnity agreement carefully. If the surety pays a claim against your bond, you owe the surety that money back — plus costs. Some indemnity agreements allow the surety to attach the principal's personal and business assets, not just the principal's insurance or business assets. Know what you are signing.

Frequently Asked Questions

What is a surety bond for a contractor?

A surety bond is a written agreement among three parties — the contractor (principal), the party requiring the bond (obligee, typically the state licensing board or project owner), and the bond company (surety). The surety guarantees that the contractor will fulfill their licensed or contracted obligations. If the contractor fails, the surety pays the obligee — and then seeks reimbursement from the contractor.

Is a surety bond the same as insurance?

No. Insurance protects the policyholder; a surety bond protects a third party. When insurance pays a claim, the insurer absorbs the loss. When a surety pays a bond claim, the contractor (principal) must reimburse the surety. A bond is effectively a line of credit with a guarantee function, not a risk-transfer instrument.

How much does a contractor license bond cost?

For a creditworthy contractor, annual premium is typically 1–3% of the bond amount. A $25,000 California CSLB bond costs roughly $150–$375 per year. Contractors with poor credit, claims history, or in high-risk trades may pay 5–15% of the bond amount or be required to post collateral.

What happens if a claim is filed against my contractor bond?

The claimant files with the surety company. The surety investigates the validity of the claim. If the claim is valid, the surety pays up to the bond penalty. The contractor then owes the surety reimbursement for the full amount paid. Repeated bond claims affect the ability to renew the bond.

Do I need both a surety bond and general liability insurance?

In most states, yes. Both are typically required for contractor licensing. General liability insurance covers accidental property damage and bodily injury caused to third parties. The surety bond guarantees the contractor's performance and compliance with licensing law. They serve different functions and neither substitutes for the other.

What is a performance bond and when is it required?

A performance bond guarantees that a contractor will complete a construction project per contract terms. It is required on federal public projects over $150,000 (Miller Act) and on state/local public projects above state Little Miller Act thresholds (varying by state from $25,000 to $200,000). Large private commercial projects often require performance bonds contractually even without a legal mandate.

Are subcontractors required to be bonded?

Subcontractors who hold their own contractor licenses in licensing states are generally required to maintain the same license bond as a prime contractor. On bonded public projects, subcontractors can make payment claims directly on the prime contractor's payment bond if the prime contractor fails to pay. Some GCs also require subcontractors to furnish their own performance and payment bonds on large subcontracts.
