In this article
Licenses, insurance, permits, and written contracts—know what to confirm before letting any contractor begin work on your home.
Key Takeaways
- Always verify a contractor's license is current and valid with your state licensing board before signing anything.
- Require proof of both general liability insurance and workers' compensation coverage before work starts.
- Get every scope, cost, and timeline detail in a written contract — verbal agreements offer little legal protection.
- Confirm which permits are required and ensure the contractor, not you, pulls the necessary ones.
- Never pay more than 10–30% upfront; tie remaining payments to verified project milestones.
Why Verification Matters Before the First Nail Is Driven
Hiring the wrong contractor — or skipping basic due diligence — can leave you with unfinished work, unpaid subcontractors, or repairs that fail a future home inspection. The good news is that a few focused checks before anyone sets foot on your property can prevent the vast majority of contractor-related problems.
This guide walks through the most important verifications to make, in plain terms, so you can hire with confidence. If you're new to managing home projects, our first renovation primer covers the broader planning process from start to finish.
Licenses, Insurance, and Bonds: The Non-Negotiables
These three credentials are the foundation of contractor vetting. Skipping any one of them exposes you to real financial and legal risk.
Verify the contractor's license through your state licensing board directly
License numbers can be falsified or may have lapsed since a contractor last showed their card. Checking the official state database confirms the license is active, covers the right trade category, and has no disciplinary history. This takes only a few minutes online and is one of the highest-value checks you can make.
Request a certificate of insurance and call the insurer to confirm coverage is current
General liability insurance covers damage to your property, while workers' compensation protects you if a worker is injured on the job. Without workers' comp, an injured worker could file a claim against your homeowner's policy. A certificate alone isn't sufficient — policies can lapse, so a quick call to the insurer to confirm active coverage is worth the extra step.
Confirm the contractor carries a surety bond appropriate for your project size
A surety bond provides a financial backstop if the contractor fails to complete the work or doesn't pay subcontractors, who can then place a lien on your property. Bonding requirements vary by state and trade, but for significant projects it adds a meaningful layer of protection.
Insist on a detailed written contract before any work begins
A verbal agreement is nearly impossible to enforce if a dispute arises. A written contract should specify the exact scope of work, materials to be used, start and estimated completion dates, payment schedule tied to milestones, and how change orders will be handled. Vague contracts create room for misunderstandings that cost time and money.
Confirm who is responsible for pulling required permits — and verify they are obtained
In most jurisdictions, the licensed contractor is legally responsible for obtaining permits for regulated work. If a homeowner pulls their own permits, they may assume liability that typically falls on the contractor. Unpermitted work can fail a home inspection at resale and may not be covered by homeowner's insurance if something goes wrong.
Structure payments as milestone-based installments, not large upfront sums
Paying a large percentage before work is complete removes your primary leverage if quality issues arise or the project stalls. A common guideline is no more than 10–30% upfront, with remaining payments tied to specific, verifiable stages of completion. Final payment should be held until you've inspected the work and confirmed it meets agreed standards.

Contracts, Permits, and Payment Terms
Once you've confirmed a contractor's credentials, the written contract and permit plan are your next lines of defense.
Permits deserve special attention. Unpermitted work can complicate a future home sale or void your homeowner's insurance — our article on when permits are required explains which projects typically need them and what happens if you skip that step. A legitimate contractor will handle permit applications as part of their scope; be cautious of anyone who suggests skipping permits to save time or money.
When reviewing bids, don't treat the lowest number as the best choice. Our guide to reading a renovation estimate can help you understand what's actually included — and what might be missing.
