To get bonded for construction, you’ll work with a licensed surety agent to submit a financial and experience package to a surety company, pass an underwriting review of your credit, capital, and track record, sign a general indemnity agreement, and pay a premium that typically runs between 0.5% and 3% of the contract value. Federal law requires performance and payment bonds on most public construction contracts above $100,000, and every state imposes similar requirements on its own public work.1Office of the Law Revision Counsel. 40 USC 3131 – Bonds of Contractors of Public Buildings or Works Private owners and general contractors often require bonds too, especially on larger projects.
Before anything else, understand what a surety bond actually is. It is a three-party guarantee. You are the principal, the project owner is the obligee, and the surety company promises the owner that you will perform. If you fail, the surety pays the owner up to the bond amount and then collects that money back from you under the indemnity agreement you signed. A bond is not insurance for the contractor. Every dollar paid out on a claim is a dollar you owe the surety.
Which Bonds You Actually Need
Most construction bonding comes in three flavors, and the project will tell you which apply.
A bid bond accompanies your bid and guarantees that if you win, you’ll sign the contract and furnish the follow-up bonds. On federal projects the bid guarantee must be at least 20% of your bid, capped at $3 million.2GovInfo. Federal Acquisition Regulation 28.101-4 Once you have a surety relationship, bid bonds are usually issued at no extra charge.
A performance bond guarantees that you’ll complete the project to the contract specifications. A payment bond guarantees your subcontractors and material suppliers will be paid; on federal work, unpaid suppliers can sue directly on the payment bond.3Office of the Law Revision Counsel. 40 USC 3133 – Rights of Persons Furnishing Labor or Material On public jobs, this matters because mechanic’s liens can’t be filed against government property, so the payment bond is the subcontractors’ only remedy. These two are almost always issued together and priced together.
The federal Miller Act sets the $100,000 threshold for both performance and payment bonds; between $25,000 and $100,000, agencies may accept alternative payment protections.4General Services Administration. The Miller Act State thresholds vary. Check the solicitation or contract documents for the exact bond types, amounts, and forms required.
Documents to Gather Before You Apply
Surety underwriting is document-heavy, and gathering the paperwork is where most contractors get stuck. Pull all of this together before you contact an agent:
- Business financial statements: balance sheet, income statement, and cash flow statement. A CPA-compiled statement is often enough for smaller bond programs. As your capacity needs grow into the mid-seven figures, expect sureties to require CPA-reviewed or audited financials.
- Personal financial statements for every owner and anyone who will sign the indemnity, showing individual assets, liabilities, and net worth. Sureties pay attention to liquid personal assets, not just real estate equity.
- A work-in-progress schedule listing every active project with original contract price, costs incurred, and estimated costs to complete. The SBA publishes Form 994F as a standard template.5U.S. Small Business Administration. SBA Form 994F – Schedule of Work in Process
- An accounts receivable aging report. A pile of old receivables flags cash flow risk.
- Resumes for key personnel, including project managers, estimators, and field supervisors, showing experience on projects of comparable size and scope.
The application itself will ask for your legal structure, tax ID, years in business, and the trades you perform. Make sure every answer matches your supporting documents. Inconsistencies cause delays or rejections.
How Underwriters Decide
Surety underwriters evaluate contractors on three Cs: character, capacity, and capital.
Character is your record and reliability. Underwriters pull personal credit, check for bankruptcies, tax liens, and judgments, and look at any litigation history. A credit score below roughly 650 generally pushes you into higher premiums or triggers a collateral requirement. Disputes with past owners are a red flag.
Capacity is your ability to actually do the work. Underwriters compare the project you want to bond against the ones you’ve completed. A contractor whose biggest finished project is $500,000 is unlikely to get bonded for a $5 million job.
Capital is the financial picture. The number underwriters focus on most is working capital, meaning current assets minus current liabilities. A common benchmark is that your working capital should equal at least 5% to 10% of the remaining cost to complete across all active projects. Net worth, debt level, and consistent profitability all feed into how much they’ll bond you for.
The Application Process Step by Step
Find a surety agent or broker who specializes in construction bonds. A specialist reads contractor financials fluently, knows which surety markets fit your size and trade, and will shepherd the file through underwriting. General insurance agents can place bonds, but construction surety is a relationship-driven niche.
Your agent submits the full documentation package to a surety. Initial underwriting typically takes anywhere from a few days to a couple of weeks, depending on bond size and the complexity of your financials.
If the surety approves you, you’ll sign a General Agreement of Indemnity. This document personally obligates you, and usually your co-owners and spouses, to reimburse the surety for any losses it pays out. It is non-negotiable, and every surety requires one before issuing any bonds. Read it carefully and understand that your personal assets are on the line.
After the indemnity is signed, you pay the premium, and the surety issues the bond certificate for you to deliver to the project owner. Much of this now happens electronically, and the federal government has moved toward accepting electronic bond transmissions in place of traditional raised seals.
What a Construction Bond Costs
Premiums are quoted as a percentage of the contract amount. Federal Highway Administration research found construction bond premiums ran from roughly 0.5% on very large contracts to 2% or more on smaller ones.6Federal Highway Administration. Chapter 4 – Benefit-Cost Analysis of Performance Bonds Contractors with strong financials and a long surety relationship pay toward the low end; newer contractors or those with credit issues pay closer to 3%. Performance and payment bonds are usually priced as a package.
Budget for a few indirect costs too. CPA-prepared financials can run from a few thousand dollars for a compilation up to $15,000 or more for a full audit. If the surety requires collateral, you may also face recording fees for liens on real estate pledged as security.
Single Job and Aggregate Limits
Approval doesn’t mean unlimited bonding. Every surety relationship comes with two limits. Your single job limit is the largest individual project the surety will bond. Your aggregate limit is the total contract backlog it will support across all active jobs at once. A contractor with a $5 million single limit and a $25 million aggregate can bid freely on projects up to $5 million as long as total backlog stays under $25 million.
The aggregate calculation generally counts unbonded work too, because every active job consumes cash and management attention. As projects wind down and cost-to-complete drops, capacity frees up. The way to grow both limits is unglamorous: complete clean projects, keep working capital strong, hold overhead steady. Sureties reward consistency.
If You Get Denied
A denial isn’t permanent, but it does mean something in the file was too thin. Ask the surety or your agent for specific feedback. The usual culprits are weak working capital, not enough experience at the requested project size, poor personal credit, or unresolved legal disputes.
If capital is the problem, the most direct fix is retaining earnings in the business instead of distributing them, or bringing in a financially strong partner or co-signer on the indemnity. If experience is the gap, take smaller bonded projects first, or work as a subcontractor on larger bonded jobs to build a completion record the surety can point to.
Small and emerging contractors have a federal backstop as well. The SBA Surety Bond Guarantee Program guarantees 80% to 90% of the surety’s loss if you default, which lowers the surety’s risk and makes approval more likely.7Congressional Research Service. SBA Surety Bond Guarantee Program The program covers contracts up to $9 million for non-federal work, and up to $14 million on federal contracts when a contracting officer certifies the guarantee is necessary. You still have to qualify as a small business and still have to pass the surety’s own evaluation. The SBA charges 0.6% of the contract price for performance and payment bond guarantees, with no fee on bid bond guarantees.8U.S. Small Business Administration. Surety Bonds The surety pays a separate fee of 20% of the bond premium to the SBA.9Federal Register. Surety Bond Guarantee Program Fees Ask your bond agent whether they participate; not all do, and switching to one who does can be what unlocks your first public project.
Some sureties also offer collateralized programs where you deposit cash or pledge real estate to secure the bond. Premiums and collateral requirements are heavier, but it’s a path to start building a surety relationship when financials alone won’t carry you.
What the Indemnity Really Means
A quick reminder worth keeping in mind as you sign. If a project owner later files a claim against your performance bond, the surety investigates before paying. You have a duty to cooperate and hand over project records. If the surety concludes the claim is valid, it can finance you to finish, hire a replacement, settle with the owner, or pay out to the bond’s penal sum. Whichever route it takes, you owe that money back under the indemnity, and the surety will pursue personal assets if a personal indemnity was signed. One large claim can end a contractor’s bonding capacity for years, which is why the real work of staying bonded happens on the jobsite, long before anyone talks about claims.
