Surety bonds are one of the most commonly required credentials for licensed contractors, yet they’re also one of the most misunderstood. Many contractors confuse bonds with insurance, don’t understand what the bond amount actually means, or overpay because they don’t know how premiums are calculated.
This guide explains how surety bonds work in plain language.
What Is a Surety Bond?
A surety bond is a three-party agreement:
- Principal — That’s you, the contractor
- Obligee — The entity requiring the bond (usually the state licensing board)
- Surety — The bonding company that guarantees your obligations
Here’s the key difference from insurance: a surety bond protects the public, not you. If a customer files a valid claim against your bond because you failed to complete a job or violated regulations, the surety pays the claim — but then you owe the surety that money back.
Think of it as a line of credit guaranteed by a third party. The state requires it so that consumers have a way to recover damages even if the contractor can’t pay.
Bond Amount vs. Bond Premium
This is where the biggest confusion lies:
- Bond amount (also called the penal sum): The maximum the surety will pay on claims. This is the number your state specifies — for example, “$15,000 surety bond required.”
- Bond premium: What you actually pay annually. This is a percentage of the bond amount.
Example
Your state requires a $15,000 contractor bond. With good credit (700+), your premium might be 2% of the bond amount, or $300 per year. You’re not putting up $15,000 — you’re paying $300 per year to maintain $15,000 in coverage.
With poor credit (below 600), that same bond might cost 10-15%, or $1,500-$2,250 per year.
Factors That Affect Your Premium
- Credit score — This is the single biggest factor. Contractors with credit scores above 700 typically pay 1-3%. Below 600, expect 5-15%.
- Bond amount — Higher bond amounts mean higher premiums (but the percentage may decrease)
- Experience — New contractors often pay slightly more than established businesses
- Claims history — Previous bond claims significantly increase your premium
- Financial strength — Some sureties review financial statements for larger bonds
Types of Contractor Bonds
License and permit bonds
The most common type. Required by your state or local government as a condition of getting or maintaining your contractor license. These are ongoing — you renew them annually as long as you hold your license.
Performance bonds
Guarantee that you’ll complete a specific project according to the contract terms. Common on commercial and government projects. The bond amount usually equals the full contract value.
Payment bonds
Guarantee that you’ll pay your subcontractors, suppliers, and laborers. Often required alongside performance bonds on public projects. Federal projects over $150,000 require both under the Miller Act.
Bid bonds
Guarantee that if you win a bid, you’ll actually enter into the contract and provide the required performance and payment bonds. Usually 5-10% of the bid amount.
How to Get Bonded
Step 1: Know your requirements
Check your state’s licensing requirements. Our state directory lists bond requirements for every trade in every state. Note the required bond amount and any specific conditions.
Step 2: Gather your information
Most bond applications require:
- Personal information and business details
- Your credit score (they’ll typically run a soft pull)
- Business financial statements (for larger bonds)
- Proof of your contractor license or application
- Work history and experience
Step 3: Get quotes
You can get bonded through:
- Surety bond companies (direct) — Companies that specialize in bonds
- Insurance agents — Many commercial insurance agents also handle bonds
- Online bond providers — Quick and convenient for standard license bonds
Get at least two or three quotes. Premiums can vary significantly between sureties, especially if your credit isn’t perfect.
Step 4: Purchase and file
Once you accept a quote, you’ll pay your premium and receive your bond. Most states require you to file the original bond with the licensing board. Some accept electronic filing.
How to Keep Your Premium Low
- Maintain good credit. This is the most impactful thing you can do. Even a modest improvement in your credit score can reduce your premium significantly.
- Avoid claims. A single bond claim can dramatically increase your rates.
- Shop around at renewal. Don’t auto-renew without checking competitors’ rates.
- Consider a larger bond. If your state offers reduced insurance requirements for contractors who carry a larger bond, the math might work in your favor.
- Build a relationship with your surety. Long-standing customers with clean records often get better rates.
Common Questions
Can I get bonded with bad credit? Yes. Many sureties specialize in “bad credit” bonds. You’ll pay a higher premium (5-15% of the bond amount), but you can still get bonded. Some companies don’t do a credit check at all for smaller bonds, though they charge maximum rates.
What happens if someone files a claim against my bond? The surety investigates the claim. If it’s valid, the surety pays the claimant up to the bond amount. You then owe the surety that money — they will come after you for repayment.
Is a surety bond the same as insurance? No. Insurance protects you. A surety bond protects your customers. With insurance, you pay a premium and the insurer absorbs valid claims. With a bond, the surety pays the claim but you’re ultimately responsible for repaying it.
How long does it take to get bonded? For standard license and permit bonds with good credit, you can often get bonded the same day. Larger bonds or applicants with credit issues may take a few days to a week.

Bond Requirements by State: What to Expect
Bond amounts vary significantly across states. Here are some examples to give you a sense of the range:
- California: $25,000 contractor bond required for all licensed contractors. One of the highest in the nation. Additional bonds may be required if you have a disciplinary history.
- Florida: $5,000 for certified contractors. County-registered contractors may have different amounts set by their local jurisdiction.
- Arizona: $2,000 - $15,000 depending on license classification. Residential contractors need a recovery fund contribution instead of a traditional bond in some cases.
- Nevada: $1,000 - $500,000+ depending on license monetary limit. Nevada’s bond amount is directly tied to the maximum project value your license allows.
- Oregon: $20,000 for general contractors, $15,000 for specialty contractors. Oregon also requires a $20,000 bond for the Construction Contractors Board.
- Georgia: $15,000 for residential and general contractors. Some classifications require higher amounts.
- North Carolina: $10,000 for intermediate contractors, higher amounts for unlimited licenses.
- Washington: $12,000 for general contractors plus a separate $6,000 bond filed with the Department of Labor & Industries.
Some states have additional bond requirements for specific situations — for example, higher bonds for contractors who have had complaints filed against them, or separate bonds for home improvement work versus commercial construction.
The Claims Process: What Really Happens
Understanding how bond claims work can help you avoid them — and know what to expect if one is filed:
How a claim gets filed
- A consumer, subcontractor, or supplier believes they’ve been financially harmed by your work or business practices
- They file a claim with your surety company, providing documentation of the alleged harm
- The surety notifies you of the claim and asks for your side of the story
- You have a set period (usually 15-30 days) to respond
Investigation
The surety investigates the claim by reviewing documentation from both parties. They’ll look at contracts, invoices, photos, correspondence, and any other relevant evidence. Some sureties use third-party investigators for complex claims.
Resolution
- Claim denied: If the surety determines the claim is invalid, they deny it. The claimant can appeal or pursue the matter in court.
- Claim paid: If the surety determines the claim is valid, they pay the claimant up to the bond amount. You then owe the surety that money (this is called “indemnification”). The surety will pursue you for repayment, including through legal action if necessary.
- Settlement: Many claims are resolved through negotiated settlements for less than the full claimed amount.
Impact on your business
A paid claim stays on your record and makes it significantly harder and more expensive to get bonded in the future. Some sureties will refuse to renew your bond after a paid claim. The best approach is to resolve disputes before they reach the claim stage — mediation, arbitration, or direct negotiation with the aggrieved party is almost always preferable to a bond claim.
Bonds for New Contractors
If you’re just starting your contracting business, getting bonded can feel like a catch-22 — you need a bond to get licensed, but you don’t have a business track record yet. Here’s what new contractors should know:
- Credit is king. Your personal credit score is the primary factor for new businesses. If your personal credit is above 650, you’ll likely qualify for standard rates.
- Instant-issue bonds. For standard license bonds under $25,000, many online providers can issue bonds instantly based solely on your credit score. No financial statements or business history required.
- Higher initial premiums are normal. Expect to pay slightly above average for your first year or two. As you build a clean track record, your rates will decrease.
- No business credit needed. Sureties evaluate new contractors on personal credit and financial strength, not business credit scores.
- Co-signers. If your personal credit is poor, some sureties allow a co-signer (spouse or business partner) with better credit to help you qualify for lower rates.
