Why Pre-Hire Verification Matters
Hiring the wrong contractor can cost you far more than the project itself. Unlicensed workers, inadequate insurance, and vague contracts are among the leading causes of homeowner disputes, incomplete projects, and costly code violations. The good news is that most problems are preventable — if you do your homework before anyone shows up with a tool belt.
This checklist walks you through the key verification steps that consumer protection agencies and experienced homeowners consistently recommend. For context on when your project will also require permits and inspections, see our guide on when permits are required. Use the checklist below as a working document — print it out, check items off, and keep copies of everything you collect.

Tools and Resources You'll Need
Most of the verification steps in this checklist require nothing more than a phone, an internet connection, and a few hours of focused attention. Having the right resources lined up before you start contacting contractors will make the process significantly smoother.
State Contractor Licensing Board Website
Used to verify a contractor's license status, license type, and any disciplinary history.
Certificate of Insurance (COI)
The formal document issued by an insurer confirming the contractor's coverage — request this directly from the contractor.
Local Building Department Contact
Used to confirm which permits are required for your specific project and to verify that permits have been properly pulled.
Written Contract Template or Attorney Review
A standard home improvement contract template helps ensure all critical terms are included; an attorney review is advisable for large or complex projects.
Better Business Bureau (BBB) Search Tool
Allows you to check complaint history and ratings for the contractor's business.
Red Flags to Watch For
Beyond the checklist items, certain behaviors during the bidding and negotiation phase are worth noting as warning signs. A contractor who pressures you to decide quickly, quotes a suspiciously low price without explanation, asks for full payment upfront, or is reluctant to provide documentation in writing deserves extra scrutiny.
Beware of Door-to-Door or Storm-Chasing Contractors
After major storms or natural disasters, unlicensed workers sometimes canvass neighborhoods offering quick, cheap repairs. These contractors may collect a deposit and disappear, or perform substandard work that fails inspection. If you didn't initiate contact, apply extra scrutiny — verify credentials through official state channels before agreeing to anything, and never pay in full before work is complete.
Verbal Agreements Offer Little Protection
A handshake deal or text message exchange is not a substitute for a signed written contract. Without a formal agreement, proving what was promised — or what was paid — becomes extremely difficult if a dispute arises. Always insist on a written contract before any work begins, regardless of how well you know the contractor.
Remember that the home maintenance decisions you make now — including who you hire — have long-term consequences for your property's safety, value, and insurability. Taking an extra day or two to verify credentials is almost always worth it.
Unpermitted Work Can Have Serious Consequences
Work done without required permits may need to be torn out and redone at your expense if discovered during a sale or insurance claim. Some homeowner's insurance policies may also deny claims related to unpermitted structures or modifications. Always confirm permit requirements upfront — our companion article explains which projects typically require official approval and why it matters.
