Hiring a builder for a new construction home is one of the biggest financial decisions you'll make—and a builder's license is your first line of defense against fraud, poor workmanship, and financial collapse mid-project. Before signing anything, you need to verify their credentials are legitimate and active. Here's exactly how to do it.
Check Your State's Licensing Board
Every builder must be licensed through their state's contractor licensing board. This is your primary verification source. Go directly to your state's official website (search "[Your State] contractor licensing board" or "[Your State] department of professional regulation") and use their public search tool. You'll typically find a name search box where you enter the builder's full legal name or company name.
Look for:
- Active status (not expired, suspended, or revoked)
- License type (general contractor, specialty contractor, or both)
- License number and issue date
- Any complaints or disciplinary actions listed
This search is free and takes five minutes. Write down the license number—you'll need it for other verifications.
Verify Through the National Association of State Contractors Boards
The NASCB maintains a national registry of licensed contractors across all states. Visit their website at www.nascb.org and use their "NASCB Member Board Directory" to find your state's licensing authority, then access their verification portal. This is especially helpful if you're hiring a builder from out of state or if you want a second confirmation that the license is legitimate.
Pull the Contractor's Bond and Insurance Information
A legitimate builder must carry:
- Contractor's license bond (typically $5,000–$20,000 depending on your state)
- General liability insurance (minimum $1 million coverage is standard)
- Worker's compensation insurance (required if they employ workers; varies by state)
Ask the builder directly for their insurance certificate and bonding information. Call their insurance provider to confirm coverage is active—don't just accept a photocopy. Request certificates of insurance naming you as an interested party. If they hesitate or provide vague answers, walk away.
Search for Complaint History
Beyond the licensing board, check:
- Better Business Bureau (BBB). Search the builder's name at bbb.org. Look at complaint patterns (are they isolated or recurring?), what was resolved, and how the builder responded.
- State Attorney General's office. Many state AGs maintain a consumer complaint database for contractors. Search "[Your State] attorney general contractor complaints."
- Google and Yelp reviews. Look for patterns in feedback about timelines, cost overruns, and warranty issues. One bad review doesn't mean much, but five complaints about the same problem is a red flag.
- Your county courthouse records. Search the builder's name for liens (unpaid subcontractors) or lawsuits. These are public records and often searchable online.
Request References and Verify Them Personally
Ask for at least three completed projects from the past two years. When you call references:
- Ask if the project finished on time and within budget
- Request to visit a completed home (not just a model)
- Ask specifically about warranty service and how issues were handled
- Inquire whether they'd hire this builder again
Don't skip this step. A builder with 20 years of experience but only one unhappy reference is better than one with a spotless license but no track record.
Check for Fraud or Bankruptcy
Search your state's court records and the federal bankruptcy court (pacer.uscourts.gov) for the builder's name. Builders who've filed bankruptcy recently or faced fraud charges are higher risk. This doesn't automatically disqualify them, but it's important context for negotiations and payment structures.
Compare Multiple Builders Efficiently
Pulling all this information manually for multiple builders takes hours. Platforms like Mercoly help you compare and find trusted New Construction & Builder Sales providers in one place, making it easier to cross-check credentials and reviews side-by-side.
Frequently Asked Questions
Q: What if a builder's license shows a complaint but they say it was resolved? A: Ask for written documentation of the resolution from the licensing board. Check whether the complaint was closed due to settlement or successful remediation. One resolved complaint is less concerning than multiple active ones.
Q: Can a builder operate legally without a state license? A: Only if the project is under a specific dollar threshold (typically $500–$3,000 depending on your state) or it's owner-built. For new construction homes, your builder must be licensed—period.
Q: How long should verification take before I sign a contract? A: Plan for one to two weeks to complete background checks, review references, and confirm insurance. Never rush this step; legitimate builders expect thorough vetting.
