Contractor bond FAQ
What is a performance bond?
A performance bond is a three-party guarantee. The surety promises the project owner (the obligee) that the contractor (the principal) will complete the contract according to its terms. If the contractor defaults, the surety may finance completion, hire a replacement contractor, or pay the obligee up to the bond amount, then seek repayment from the contractor and any indemnitors.
Is a performance bond the same as insurance?
No. Insurance transfers risk to the insurer. A surety bond is closer to a credit guarantee: if the surety pays a valid claim, the contractor and indemnitors are expected to reimburse it under the indemnity agreement.
Who requires performance bonds?
Federal, state, and local public owners require them on most public construction contracts above set dollar thresholds. Many private owners, lenders, and general contractors require them as well, especially on larger projects.
How much does a performance bond cost?
The premium is a percentage of the contract or bond amount, set by the surety based on your credit, financial statements, experience, and the job itself. There is no single published rate, so the only way to know your price is to apply.
What is bonding capacity?
Bonding capacity is the size of a single job and the total backlog of bonded work a surety is willing to support for your company. It grows with your working capital, net worth, profitable track record, and banking relationships.
Do I need a payment bond too?
On most public projects, yes. Performance and payment bonds are usually issued together: the performance bond protects the owner, and the payment bond protects subcontractors and suppliers who might otherwise file liens.
How long does it take to get bonded?
A small single bond for an established contractor can move quickly once the application and financials are complete. A first-time account or a large program takes longer because the surety reviews financial statements, work in progress, and references.
Is a quote the same as a bond?
No. A quote is not a binder and does not obligate a surety to issue a bond. A bond exists only once the surety executes it.
What happens if the contractor defaults?
The obligee notifies the surety and declares default under the contract. The surety investigates and may finance the original contractor, arrange a replacement, take over the work, or pay the obligee up to the penal sum.
Is the bond amount the contract amount?
Often the penal sum equals 100% of the contract price, but the owner sets the requirement.
Does a performance bond cover warranty work?
Some bond forms include a warranty period; others require a separate maintenance bond.
Who can claim on a payment bond?
Generally subcontractors, suppliers, and laborers who furnished work or materials for the project, within limits set by the bond and the governing law.
Are there deadlines?
Yes. Federal and state laws set notice and lawsuit deadlines, and missing them can bar a claim.
Why do public projects need payment bonds?
Liens usually cannot attach to public property, so the payment bond provides substitute protection.
How much is a bid bond?
The obligee sets the bid security amount, often a percentage of the bid. Many sureties issue bid bonds for established accounts without a separate charge, but practices vary.
What if I win and cannot get final bonds?
The owner can claim on the bid bond, typically for the difference between your bid and the next acceptable bid, up to the bond amount.
Can I get a bid bond without a surety relationship?
Usually you need to be underwritten first, because the surety is committing to provide final bonds.
How long does a maintenance bond last?
The owner sets the term, commonly one or two years after acceptance, though longer periods occur.
Is it separate from the performance bond?
Sometimes. Some performance bonds include warranty obligations; other owners require a separate maintenance bond.
What is a typical amount?
The owner sets it, often a percentage of the contract price.
Who needs a supply bond?
Suppliers and manufacturers contracting to deliver materials or equipment to public owners or contractors.
Does it cover installation?
Usually not. Installation is a construction obligation covered by a performance bond.
How are they underwritten?
Similar to performance bonds, with emphasis on the supplier's finances and delivery record.
Who sets the bond amount?
The licensing authority or the city or county issuing the permit.
Is credit checked?
Often, though smaller license bonds may be issued with limited underwriting.
Is it the same as a performance bond?
No. It guarantees compliance with licensing or permit rules, not completion of a specific contract.
Can a new company get bonded?
Yes, usually starting with smaller bonds and relying on owners' credit and experience.
Do I need audited financial statements?
Not for small bonds. Larger programs commonly require reviewed or audited statements from a CPA.
Why does the surety want personal indemnity?
Owners' personal indemnity aligns their interests with the surety's and provides additional recovery if a loss occurs.
Is there a formula for bonding capacity?
Sureties use working capital and net worth as starting points, but each applies its own judgment to your experience and work type.
Does my backlog affect capacity?
Yes. Aggregate capacity covers the uncompleted portion of all bonded work.
Can capacity shrink?
Yes, after a loss year, a problem job, or weakened financials.
Why don't you publish a rate?
Sureties price each account individually based on underwriting. A generic rate would not reflect your credit, finances, or the job.
Does the bond premium change if the contract changes?
Change orders that increase the contract price usually increase the premium.
Is the premium refundable?
Typically the premium is earned once the bond is issued, though terms vary.
What is the Miller Act?
A federal law requiring performance and payment bonds on federal construction contracts above a threshold set in the Federal Acquisition Regulation.
What is a Little Miller Act?
A state law requiring bonds on state and local public works, modeled on the federal statute.
Do thresholds vary?
Yes, by state and sometimes by type of public entity. Check the statute and the bid documents.
How current must financial statements be?
Sureties generally want fiscal year-end statements within months of year-end and interim statements for larger programs.
What is a WIP schedule?
A work-in-progress schedule listing each open job with contract amount, costs to date, estimated costs to complete, billings, and gross profit.
Do I need a business plan?
For larger or growing programs, a short plan explaining your strategy helps.
