When you're investing $300K–$500K+ in a new construction home, a builder's insurance and bonding aren't just paperwork—they're your financial safety net. Poor coverage or missing bonds can leave you holding the bag if the project stalls, quality fails, or the builder disappears mid-build.
What Builder Insurance Actually Covers
Builder's risk insurance protects the structure itself during construction—think theft, weather damage, or accidental fire before you take possession. This typically costs 0.5% to 1% of the total project cost and is mandatory for construction loans.
General liability insurance covers third-party injuries or property damage on the job site. If a subcontractor trips over debris or damages a neighbor's property, this policy kicks in. Standard coverage runs $1M–$2M and is non-negotiable for any legitimate builder.
Workers' compensation is required in most states if the builder has employees (not just subcontractors). This protects workers injured on the job and keeps you from becoming liable for their medical bills.
The critical gap: Many buyers assume their homeowner's insurance kicks in during construction. It doesn't. The builder's policies are your only protection until closing.
Bonding: Your Guarantee the Job Gets Finished
A performance bond is a three-party agreement between the builder, a bonding company, and you (the homeowner). If the builder fails to complete the work or abandons the project, the bonding company either hires a new contractor to finish or reimburses you—up to the bond amount.
A payment bond ensures subcontractors and suppliers get paid, preventing liens against your property. This matters because if a roofer doesn't get paid, they can legally place a lien on your home, even if you paid the builder in full.
Bonds typically cost 1–3% of the total contract price and are required for construction loans over $500K in many cases. Don't assume a builder has them—ask to see the surety company name, bond number, and coverage limits in writing.
Red Flags to Spot Before You Sign
Check the builder's insurance actively. Request a certificate of insurance directly from their agent, not from the builder's office. Verify the policy is current and won't expire mid-project. A builder operating without active coverage is an immediate disqualification.
Confirm bond amounts match your contract. If your home costs $450K and the performance bond is only $100K, you're underprotected. Bonding companies issue bonds proportional to the contract—the amount should equal your total project cost.
Look for complaint history. Check your state's Attorney General office, the Better Business Bureau, and local contractor licensing boards. Multiple liens, abandoned projects, or insurance lapses are patterns, not one-off mistakes.
Verify the surety company's reputation. Not all bonding companies are equal. Use A.M. Best or the National Association of Surety Bond Producers to confirm the bonding company is legitimate and solvent.
What to Ask Your Builder Before Hiring
- "Can you provide a certificate of insurance showing builder's risk, general liability, and workers' comp—all active and dated?"
- "What are the bond amounts, and who is your surety company?"
- "Are there any outstanding liens, claims, or canceled policies from the past three years?"
- "Who do I contact if there's a problem during construction—you directly, or your construction manager?"
Insurance and bonding vary significantly by region and project size, so don't rely on one builder's standard. Compare at least two or three builders' coverage details side-by-side. If you're overwhelmed navigating insurance documents and builder comparisons, platforms like Mercoly help you find and compare trusted builders with verified credentials in one place.
What This Protects You From
A properly insured, bonded builder protects you from:
- Paying for incomplete work with no legal recourse
- Liens filed by unpaid contractors
- Unexpected cost overruns you can't recover
- Liability if someone is injured on site
- Discovering gaps in coverage after the builder goes bankrupt
Frequently Asked Questions
Q: If a builder goes bankrupt mid-project, does the performance bond cover the cost to finish? Yes, up to the bond amount. The surety company either funds a replacement contractor or reimburses you directly, depending on the bond terms.
Q: Can I require higher bond amounts than what the builder typically carries? In most cases, yes—especially if you're financing through a commercial lender, who may mandate specific minimums anyway.
Q: What happens if I find a lien against my property after closing? The payment bond should have prevented this, but if it slips through, you may need to pay the lienholder or dispute it in court. This is why verifying the payment bond before closing is critical.
Start by requesting insurance certificates and bond documents from any builder you're considering—if they push back or delay, that's your answer.
