Construction bonds provide essential financial protection for owners and ensure contractors fulfill their obligations on building projects. This comprehensive guide explains the different types of construction bonds (including bid bonds, performance bonds, and payment bonds), how surety bonds work in practice, who pays for them, and when they’re required. We’ll break down the critical differences between construction bonds and insurance while sharing real-world examples and ARE exam strategies.

This post includes everything you need to understand construction bonds, whether you’re preparing for the ARE exam or managing real-world construction projects.
Understanding Construction Bonds: Beyond the Basics
Imagine you’re six months into a high-profile public project when your general contractor suddenly vanishes. No warning, just gone—along with your project schedule and client confidence.
This nightmare scenario happens more often than most architects realize. But there’s a financial safety net designed specifically to protect projects in these situations: construction bonds.
Contractors who disappear mid-project aren’t practicing magic – they’re practicing malpractice. Luckily, bonds are the rabbit you can pull out of your hat.
When contingency planning isn’t enough to save a project, bonds provide that critical layer of protection that can mean the difference between project success and failure.
Understanding bonds isn’t just critical for real-world practice—it’s essential knowledge for the ARE exam. Yet many professionals confuse bonds with insurance or misunderstand their fundamental purpose.
Let’s decode construction bonds once and for all.
What Are Construction Bonds?
Construction bonds are financial guarantees that ensure obligations are met on a project. They function as a protection mechanism for project owners and other stakeholders when contractors fail to fulfill their contractual obligations.
Unlike insurance, which spreads risk among many policyholders and doesn’t require repayment after a claim, bonds function more like co-signed loans. When a contractor fails to meet their obligations, the bond company (surety) steps in—but they’ll recover every penny from the contractor afterward.
Think of it this way:
- Insurance is like your car insurance. If you crash, the insurance company pays for damages, and you don’t pay them back directly (though your rates might increase).
- Bonds are like having someone co-sign your student loan. If you stop making payments, the co-signer covers it—but they’ll definitely pursue you to recover their money.
If insurance is like having a safety net, a bond is like having a parachute with someone holding a gun to the skydiver’s head saying “This better open!”
The key distinction? Insurance protects against unforeseen risks. Bonds guarantee performance.
The Three-Party Relationship in Construction Bonds
Every construction bond involves three key parties:
- Principal (the contractor) who purchases the bond and promises to perform
- Surety (the bonding company) who guarantees the principal’s obligations
- Obligee (the project owner) who is protected by the bond
Surety companies are like that friend who will loan you money but then texts you every day asking “So… when do I get paid back?” – except with legal authority and better collection methods.
This relationship ensures that even if the contractor fails, the project can still move forward with minimal disruption.
Types of Construction Bonds Every Professional Should Know
Not all bonds serve the same purpose. Here are the six types you need to understand:
1. Bid Bonds
Purpose: Ensures that a contractor will sign a contract if they win the bid.
Real-world example: A contractor submits the lowest bid at $500,000 but then realizes they made a calculation error and wants to back out. The next lowest bid is $600,000. The bid bond would compensate the owner for the $100,000 difference.
A bid bond is like those plastic handcuffs they use at weddings for the groom – a symbolic reminder that you’ve made a commitment and there will be consequences if you run.
Bid bonds are a critical part of preconstruction activities and are typically one of the first bond types you’ll encounter on a project.
2. Performance Bonds
Purpose: Guarantees that the contractor will complete the work according to contract.
Real-world example: If a contractor goes bankrupt mid-project, the performance bond allows the owner to hire another contractor to finish the work with the bond company covering the costs.
A performance bond is the construction equivalent of those parent-child leashes you see at Disney World – freedom to move around, but only so far before someone yanks you back.
3. Payment Bonds
Purpose: Ensures subcontractors and suppliers get paid.
Real-world example: If a general contractor refuses to pay a subcontractor, the sub can file a claim against the payment bond to receive their money without having to file a mechanics lien on the project.
4. Maintenance/Warranty Bonds
Purpose: Covers defects after the project’s completion.
Real-world example: Six months after a school is completed, the roof starts leaking. The owner can file a claim against the warranty bond, and the contractor must return to fix the issues.
Warranty bonds are especially important during project closeout when transitioning from construction to occupancy.
5. Subdivision Bonds
Purpose: Guarantees developers will complete public infrastructure.
Real-world example: A developer builds a new neighborhood but hasn’t finished the promised public sidewalks. The city can use the subdivision bond to hire another contractor to complete that work.
6. License & Permit Bonds
Purpose: Ensures compliance with regulations.
Real-world example: A roofing company gets a license bond before doing work, and if they violate building codes, the bond will compensate affected homeowners.
How Do Construction Bonds Work?
When a contractor purchases a bond, they’re not buying protection for themselves—they’re providing a guarantee to the project owner. This is a fundamental concept many people misunderstand.
Here’s the process:
- The contractor applies for a bond through a surety company
- The surety evaluates the contractor’s financial stability, experience, and capacity
- If approved, the contractor pays a premium (typically 1-3% of the bond amount)
- The surety issues the bond to the project owner
- If the contractor defaults, the surety steps in to fulfill the obligation
- The surety then recovers costs from the contractor
This process ensures projects can continue even when contractors fail to meet their obligations.
When Are Construction Bonds Required?
Not all projects require bonds, but they’re commonly mandated in these situations:
Public Projects
Government construction projects almost always require bonds because taxpayer money is at stake. This creates a stark difference in how public versus private clients approach risk management.
Federal Requirements
The Miller Act requires performance and payment bonds for federal construction projects exceeding $150,000. Similar “Little Miller Acts” exist at state and local levels.
Private Projects
While not always required by law, many private owners require bonds for large or high-risk projects, especially when working with new contractors or when significant financial risk is involved.
The more public money or higher financial risk involved, the more likely bonds will be required.
Common Misconceptions About Construction Bonds
There are numerous common misconceptions about construction bonds. Let’s clear up some of the most persistent myths:
Misconception #1: “Bonds are the same as insurance.”
Reality: While both involve financial protection, bonds are financial guarantees of performance, while general liability insurance covers unforeseen risks. The contractor remains responsible for repaying the surety if a bond is called.
Misconception #2: “Bonds protect the contractor.”
Reality: Bonds protect the owner, subcontractors, and the project—not the contractor. Contractors purchase bonds as a requirement, not as protection for themselves.
Another misconception: Contractors don’t get superpowers when they’re “bonded and insured” – though the way some advertise it, you’d think they could leap tall buildings in a single bound.
Misconception #3: “If a contractor defaults, the surety just pays.”
Reality: The surety may pay initially, but they will vigorously pursue recovery from the contractor. Some sureties will even help the owner find a replacement contractor.
Unlike with bail bonds, no one’s sending Dog the Bounty Hunter after your contractor if they default – though sometimes you might wish they would!
Misconception #4: “Bonds only apply to big government projects.”
Reality: While public projects almost always require bonds, many large private projects also require them, especially when working with new contractors.
Real-World Application: How Bonds Save Projects
Consider this scenario from a real project:
On a public library construction project, the general contractor and excavator were in a heated dispute over $200,000 worth of site work. The excavator threatened to place a mechanics lien on the project, which would have halted progress immediately.
To keep the project moving, the general contractor obtained a payment bond specifically for the disputed amount. This allowed the legal dispute to continue separately while the project progressed uninterrupted.
This solution:
- Protected the owner from delays
- Kept the schedule intact
- Provided a pathway to resolve the payment dispute
This demonstrates how bonds can be powerful tools for project protection, especially when unexpected contingencies arise during construction.
Bond Management and Costs: What You Need to Know
Who Pays for Construction Bonds?
The contractor pays for the bond, but the cost is typically included in their bid price—meaning the project owner indirectly pays for it through the contract amount.
Factors Affecting Bond Cost
Several factors determine how much a contractor pays for bonds:
- Financial strength and credit history
- Experience and track record
- Size and duration of the project
- Type of bond required
- Relationship with the surety company
Bond premiums of 1-3% might not sound like much, but neither does “just a small leak in the roof” – and we all know how that turns out.
For financially stable contractors with good track records, bond premiums might be as low as 1% of the contract value. For less established contractors, rates can reach 3-5% or higher.
Bonds are just one aspect of construction quality assurance and quality control systems that help ensure projects meet required standards.
Construction Bonds and the ARE Exam
Bond questions can appear in multiple divisions of the ARE, but they’re most common in:
- Practice Management (PcM) – When assessing business risks and financial stability
- Project Management (PjM) – In contract requirements sections
- Construction & Evaluation (CE) – Regarding bidding, contract enforcement, and handling defaults in projects
We’ve written many ARE Practice Questions inside our CE 101 course that test your knowledge of bonds in various scenarios. Each question comes with a detailed explanation to help you master these concepts for exam day. You can access these practice questions and much more through our ARE 101 Course Membership.
Remember, on the ARE practice questions, if the question involves a public project and bonds, the answer is almost always “Yes, bonds are required” – kind of like how the answer to “Does this project need more money?” is also always yes.
When approaching bond questions on the Construction & Evaluation (CE) exam, remember these key principles:
- If it’s a public project, assume bonds are required
- If the question asks who is protected, the answer is almost always the owner or the project
- If a contractor defaults, the bonding company steps in to help the owner complete the project
Understanding the relationship between bonds and contract documents is also crucial for exam success.
It’s worth noting that understanding bonds is not just important for the ARE exam, but also for the Construction Documents Technologist (CDT) exam. The CDT exam tests your knowledge of the construction documentation process, including how bonds factor into project delivery and contract administration.
Why Construction Bonds Matter
When architects and construction professionals truly understand construction bonds, they gain a powerful advantage both in practice and on the ARE exam.
This knowledge transforms how you view project risk and protection. Rather than seeing bonds as just another contractual requirement, you’ll recognize them as essential tools that can save projects, protect clients, and maintain your professional reputation when things go sideways.
The most successful professionals don’t just design beautiful buildings—they understand the business realities that allow those designs to become reality. Construction bonds represent that critical intersection between design aspirations and successful project execution.
Through proper application of bonds, along with careful contingency planning, you can ensure your projects have the protection they need to succeed—even when the unexpected happens.
Frequently Asked Questions About Construction Bonds
1. How much do construction bonds typically cost?
Bond premiums typically range from 1-3% of the bond amount for established contractors with good credit. New contractors or those with poor financial histories may pay 3-5% or more.
2. Can small or new contractors get bonded?
Yes, but it may be more challenging and expensive. New contractors might need to start with smaller bonds and build a track record, or they might need to provide additional collateral or personal guarantees.
3. Are bonds required on all construction projects?
No. Bonds are almost always required on public projects but are optional on many private projects, especially smaller ones. The requirement often depends on project size, risk, and the owner’s preference.
4. How do I verify a contractor is properly bonded?
Ask for a copy of their bond certificate and contact the surety company directly to verify. Never accept a “letter of bondability” as proof of an actual bond—this is just a statement that the contractor could potentially get a bond.
5. What happens if a bonded contractor goes bankrupt?
The surety company will step in to fulfill the contractor’s obligations, either by paying for completion of the work or by finding another contractor to complete it. The owner is protected from financial loss related to the contractor’s default.
