Surety bonds are one of the most misunderstood aspects of contractor insurance. Contractors hear "you need a $10,000 bond" and assume it's another insurance policy. It's not. A bond is a guarantee — not to you, but to your client or to the public — that you'll perform as promised. If you default, the bond pays. And then you pay the surety back. Bonds protect others from your failure. Insurance protects you from claims against you. They serve opposite functions.
In Texas, surety bonds are required in three main contexts: to obtain certain licenses, to bid on public work, and often as a contract requirement on private commercial projects. Understanding when bonds are required, what types exist, how bonding capacity works, and how bonds interact with your insurance program is essential if you're bidding on anything larger than small residential work.
This guide explains how surety bonds differ from insurance, what types of bonds Texas contractors encounter, when bonds are required, how public work bonding works in Texas, how to build bonding capacity, and what bonds cost.
Surety Bonds vs. Insurance: The Core Difference
The easiest way to understand the difference: insurance is a two-party contract, bonds are a three-party contract. And the key difference is indemnity — who ultimately pays when something goes wrong.
Insurance: two parties, insurer pays
In an insurance contract, you (the insured) pay a premium to the insurance company (the insurer). If a covered claim occurs, the insurer pays the claim and you do not owe the insurer back. That's the entire point of insurance: transferring risk to the insurer in exchange for a premium.
Example: Your general liability policy covers a third-party claim. The carrier pays $200,000 to settle the claim. You don't reimburse the carrier. The premium you paid is the full cost of coverage.
Surety bond: three parties, you pay the surety back
A surety bond involves three parties:
- Principal: You, the contractor. You're the one whose performance is being guaranteed.
- Obligee: The party who requires the bond — a government agency, a project owner, or a client. They're the beneficiary of the bond.
- Surety: The bonding company that issues the bond and guarantees your performance to the obligee.
If you fail to perform — you don't complete the work, you don't pay your subs, you violate the terms of a license — the obligee makes a claim against the bond. The surety investigates, and if the claim is valid, the surety pays the obligee. Then the surety comes back to you (the principal) and demands reimbursement, plus costs. This is called the indemnity obligation. When you apply for a bond, you sign an indemnity agreement that makes you personally and corporately liable to reimburse the surety for any claims paid.
In other words: the bond protects the obligee, not you. It's a credit instrument that guarantees your performance. The premium you pay for the bond is compensation to the surety for extending that guarantee, but it doesn't absolve you of liability. If the bond pays a claim, you owe the money back.
Bonds are not insurance. Contractors often think "I have a bond, so I'm covered if something goes wrong." Wrong. The bond covers the project owner or the public, not you. If a claim is paid, you're personally liable to reimburse the surety. Insurance transfers risk away from you. Bonds guarantee your performance to others, but you still carry the financial risk.
Types of Surety Bonds Texas Contractors Encounter
License and permit bonds
License bonds (also called compliance bonds) are required by regulatory agencies as a condition of obtaining a license or permit to operate in certain trades. The bond guarantees that you'll comply with applicable laws, regulations, and licensing requirements. If you violate the rules and the agency incurs costs — investigation, enforcement, consumer restitution — the bond pays those costs, and you reimburse the surety.
Common license bonds in Texas:
- Electrical contractor license bond: Many Texas cities and counties require electrical contractors to post a bond before issuing a license to operate. Bond amounts vary — commonly $5,000 to $10,000.
- Plumbing contractor license bond: Required in some jurisdictions for licensed plumbers.
- HVAC contractor license bond: Required in certain municipalities.
- General contractor license bond: Texas does not have a statewide general contractor license, so these are rare. Some municipalities have their own contractor licensing with bond requirements.
- Auto dealer bond, mortgage broker bond, etc.: Numerous non-construction trades require license bonds. If you're entering a regulated profession, ask the licensing agency whether a bond is required.
License bonds are typically easy to obtain. Bond amounts are modest ($5,000 to $25,000), and the annual premium is a small percentage of the bond amount — often $100 to $500 per year. Sureties issue license bonds based primarily on credit score. A clean credit history and no criminal record are usually sufficient.
Bid bonds
A bid bond guarantees that if you're awarded a contract after submitting a bid, you'll enter into the contract and provide the required performance and payment bonds. If you're awarded the job and then refuse to sign the contract, the bid bond compensates the project owner for the difference between your bid and the next lowest bid, up to the bond amount (typically 5% to 10% of the bid).
Bid bonds are almost always required on public work (federal, state, county, municipal projects). They're occasionally required on large private projects. The purpose: to prevent contractors from submitting lowball bids with no intention of performing, which wastes the owner's time and money.
Bid bonds are issued at no cost to the contractor. The surety issues the bid bond as part of underwriting whether they'll provide the performance and payment bonds if you win. You only pay a premium if you're awarded the contract and the performance and payment bonds are issued.
Performance bonds
A performance bond guarantees that you'll complete the work according to the contract terms. If you default — you abandon the job, you fail to meet specifications, you go bankrupt mid-project — the surety steps in. The surety can:
- Finance you to complete the work.
- Hire another contractor to complete the work.
- Pay the project owner the bond amount (typically 100% of the contract price) so they can complete the work themselves.
Performance bonds are required on most public work (federal, state, and local government projects) and are often required on large private commercial projects. On public work, the bond amount is typically 100% of the contract price. On private work, bond amounts may be negotiated.
Performance bond premiums are calculated as a percentage of the contract amount. For contractors with established bonding capacity and strong financials, the rate is typically 0.5% to 3% of the contract value. A $1 million contract might require a $5,000 to $30,000 performance bond premium.
Payment bonds
A payment bond guarantees that you'll pay your subcontractors, suppliers, and workers. If you fail to pay them, they can make a claim against the payment bond. The surety investigates and, if the claim is valid, pays the sub or supplier, then seeks reimbursement from you.
Payment bonds are almost always required alongside performance bonds on public work. Texas public work statutes require payment bonds on certain projects (see Public Work Bonds below). On private work, payment bonds are less common but may be required on large projects.
Payment bond premiums are typically bundled with performance bond premiums. The combined premium covers both the performance and payment bonds.
Maintenance bonds (warranty bonds)
A maintenance bond (or warranty bond) guarantees that you'll correct defects in materials or workmanship discovered during a specified warranty period after project completion. These are less common than performance and payment bonds and are typically required only on public work or high-value private projects.
The bond period matches the warranty period specified in the contract — often one to two years. If defects arise and you refuse to correct them, the owner makes a claim against the maintenance bond.
Public Work Bonds in Texas
Texas law requires performance and payment bonds on certain public construction projects. The requirements depend on the type of governmental entity and the project value. Rather than cite specific dollar thresholds — which can change as statutes are updated — this section describes the general structure. Verify current requirements with the awarding agency or your attorney when bidding public work.
State public work
Texas Government Code Chapter 2253 governs bonding requirements for state public work. Generally, contractors awarded state construction contracts above a specified threshold must furnish performance and payment bonds. The bond amounts are typically set at 100% of the contract price. The statute specifies who may serve as surety (authorized surety companies, not individuals).
County and municipal public work
Counties and municipalities follow similar bonding requirements under Texas Government Code Chapter 2253 and Local Government Code provisions. Each governmental entity may have additional requirements in their contracting rules. Bond amounts are typically 100% of the contract price for both performance and payment bonds.
School district and other local government projects
School districts and other local government entities are subject to public work bonding requirements under Education Code and Local Government Code provisions. As with state and municipal work, bond requirements are generally tied to contract value thresholds. Verify the specific requirements in the bid documents for each project.
Federal public work (if bidding on federal projects in Texas)
Federal construction contracts are governed by the Miller Act, which requires performance and payment bonds on federal projects exceeding a specified threshold (currently $150,000, but verify current figures). The bond amounts are 100% of the contract price. Miller Act bonds must be issued by sureties listed on the U.S. Treasury Department's approved list.
Little Miller Acts (Texas prompt payment and retainage laws)
Texas has prompt payment statutes and retainage rules that interact with public work bonding. Payment bonds on public work provide a remedy for unpaid subs and suppliers when the general contractor fails to pay. Subs have statutory claim procedures and deadlines. If you're a subcontractor on bonded public work, understand your payment bond claim rights under Texas law.
Private Work Bond Requirements
Private project owners — developers, corporations, property owners — are not required by law to demand bonds, but many do, especially on large projects. When bidding private commercial work, the contract may require performance and payment bonds to protect the owner and lower-tier subs.
When private owners require bonds
- Large project value: Projects over $1 million often include bond requirements.
- Unfamiliar contractor: If the owner hasn't worked with you before, they may require bonds to reduce risk.
- Design-build or fast-track projects: Projects with overlapping phases and early procurement may require bonds to guarantee completion.
- Lender requirements: Construction loans often require the general contractor to be bonded as a condition of financing.
Bond amounts on private work
On private work, bond amounts are negotiable. Some owners require 100% performance and payment bonds (same as public work). Others require 50% bonds or performance bonds without payment bonds. Read the contract carefully and understand what you're being asked to provide before signing.
How Bonding Capacity Works
Your bonding capacity is the maximum value of work you can have bonded at any one time. It's determined by the surety based on your financial strength, work-in-progress capacity, experience, and creditworthiness. Bonding capacity is not unlimited, and it's separate from your ability to perform the work.
What sureties evaluate when determining bonding capacity
- Financial statements: Sureties require CPA-prepared or reviewed financial statements (balance sheet, income statement, cash flow statement). They evaluate your working capital, net worth, equity, and liquidity.
- Work-in-progress (WIP): How much work do you currently have under contract? Sureties want to see that you're not overextended. Most sureties limit total bonded work to 10x to 20x your working capital.
- Experience and track record: Have you successfully completed projects of similar size and complexity? Sureties look at your project history, references, and whether you've ever defaulted on a bonded project.
- Credit history: Personal and business credit reports are reviewed. Poor credit, judgments, liens, or bankruptcies reduce bonding capacity or make bonding unavailable.
- Resumes of key personnel: Who runs the company? What's their construction experience? Sureties want to see experienced leadership.
How to build bonding capacity over time
Most contractors don't start with large bonding capacity. You build it over time by successfully completing bonded projects, strengthening your balance sheet, and establishing a relationship with a surety. The process:
- Start small: Bond small projects first ($50,000 to $250,000). Successfully complete them. Build a track record with the surety.
- Strengthen financials: Retain earnings, manage cash flow, reduce debt, and build working capital. Sureties base capacity on your financial strength.
- Maintain clean books: Timely financial reporting, clean audits or reviews, and accurate WIP schedules demonstrate operational discipline.
- Build a relationship with a surety: Work with a surety agent who specializes in construction. They'll guide you on what sureties need and help you grow capacity as your business grows.
Bonding capacity limits
Your bonding capacity has two limits:
- Single project limit: The largest single project you can bond. Often 2x to 5x your working capital.
- Aggregate limit: The total value of all bonded work you can have in progress at once. Often 10x to 20x your working capital.
Example: A contractor with $500,000 in working capital might have a single project limit of $2.5M and an aggregate limit of $10M. They can bond multiple projects totaling up to $10M, but no single project can exceed $2.5M.
Start building bonding capacity before you need it. If you plan to bid on public work or large commercial projects, establish a relationship with a surety and obtain a bonding line early. Sureties evaluate your financials, track record, and credit. Building capacity takes time. Waiting until you have a project that requires a bond means you may not qualify, or the underwriting process will delay the project. Start early.
What Surety Bonds Cost
License and permit bonds
License bonds are the cheapest. Annual premiums range from $100 to $500 for bonds up to $25,000. The premium is based primarily on credit score. Contractors with good credit (700+) pay the lowest rates. Poor credit increases the premium or results in a declined bond.
Performance and payment bonds
Performance and payment bond premiums are calculated as a percentage of the contract value. Rates depend on the contractor's financial strength, bonding capacity, experience, and the project type.
Typical rates:
- Contracts under $500,000: 1% to 3% of the contract value. A $250,000 contract might cost $2,500 to $7,500 in bond premium.
- Contracts $500,000 to $2 million: 0.75% to 2%. A $1M contract might cost $7,500 to $20,000.
- Contracts over $2 million: 0.5% to 1.5%. Large projects with strong contractors pay the lowest rates.
Factors that reduce bond premiums: strong financials, established bonding relationship, clean project history, experienced personnel. Factors that increase premiums: weak financials, first-time bonding, prior bond claims, high-risk project types (complex, fast-track, design-build).
Who pays the bond premium?
On public work, the bond premium is a reimbursable cost to the contractor. You include the bond premium in your bid, and the project owner pays it as part of the contract price. On private work, the same principle usually applies — the bond cost is built into your bid and passed to the owner.
Surety Bonds and Insurance: How They Interact
Sureties require contractors to carry adequate insurance before issuing bonds. The reason: if something goes wrong on a bonded project and the surety has to complete the work or pay a claim, the surety wants your insurance to respond first. This reduces the surety's exposure and your indemnity obligation.
Insurance requirements for bonding
To obtain performance and payment bonds, sureties typically require you to carry:
- General liability: Minimum $1M per occurrence, $2M aggregate. Higher limits for large projects.
- Workers' compensation: Required if you have employees. Sureties will not bond contractors who don't carry workers' comp.
- Commercial auto: Required if you operate vehicles.
- Builders risk (on some projects): Covers the project during construction. Required on many bonded projects.
- Umbrella: Adds excess liability limits above your GL, auto, and workers' comp. Often required on large projects.
Sureties verify your insurance before issuing bonds. If your coverage lapses during a bonded project, the surety may require you to reinstate coverage immediately or risk bond cancellation.
Common Mistakes Contractors Make with Bonds
Thinking bonds are insurance
Bonds protect the project owner or the public, not you. If a claim is paid, you reimburse the surety. Insurance protects you by transferring risk to the insurer. Understand the difference before you sign a bond application.
Not building bonding capacity early
Bonding capacity takes time to establish. If you wait until you need a bond to approach a surety, you may not qualify, or the underwriting process will delay the project. Build a relationship with a surety agent early, even if you're not bidding bonded work yet.
Ignoring the indemnity agreement
When you apply for a bond, you sign an indemnity agreement making you personally and corporately liable to reimburse the surety for any claims. Many contractors don't read this. The indemnity is often unlimited and survives corporate dissolution. Understand what you're signing.
Letting insurance lapse on a bonded project
Sureties require continuous insurance coverage during bonded projects. If your GL or workers' comp lapses, the surety can cancel the bond, which terminates your contract with the project owner. Keep coverage active and provide updated certificates to the surety throughout the project.
Not understanding public work claim procedures
If you're a subcontractor on a bonded public project and the GC doesn't pay you, you have payment bond claim rights under Texas law. But there are strict notice and timing requirements. Miss the deadlines, and you lose your claim rights. If you work on public projects, understand the payment bond claim process.
