What Is a Licensed and Bonded Contractor — and Why It Matters

"Licensed, bonded, and insured." You see it on every contractor's truck, website, and business card. But most homeowners have no idea what these terms actually mean — or how to verify that a contractor's claims are real.

This matters more than you might think. Hiring an unlicensed contractor in Arizona can leave you personally liable for injuries on your property, void your homeowner's insurance, and give you almost no legal recourse if the work is shoddy or the contractor disappears.

Here is exactly what each term means and what you should do to verify it.

A contractor's license is issued by a state regulatory body — in Arizona, that is the Arizona Registrar of Contractors (ROC). To get licensed, a contractor must:

• Pass a trade knowledge exam
• Pass a business and law exam
• Demonstrate a minimum level of experience in their trade
• Pay licensing fees
• Maintain the license with continuing education requirements

The license tells you the contractor has been vetted by the state, knows the applicable building codes, and is legally authorized to perform the work they are advertising.

In Arizona, most residential and commercial contracting work requires an ROC license. This includes general contracting, electrical, plumbing, HVAC, roofing, and more. Landscaping that involves irrigation or significant grading also requires a license.

Go to roc.az.gov and search by the contractor's name, company name, or license number. You will see:

• Whether the license is active or expired
• What type of work they are licensed for
• Any complaints or disciplinary actions on record
• Their bond and insurance status

This takes about 60 seconds and is one of the most important things you can do before hiring anyone.

• You may be unable to get permits pulled for the work
• If a worker is injured on your property, you could be held liable
• Your homeowner's insurance may deny claims related to the work
• You have limited legal recourse if the work is defective
• In Arizona, you cannot file a complaint with the ROC — that protection only exists for licensed contractors

A contractor's bond (technically called a surety bond) is a financial guarantee that protects you if the contractor fails to complete the job, causes damage, or violates the terms of your contract.

Here is how it works: the contractor pays a bonding company a premium. If the contractor fails to perform — abandons the job, steals materials, causes damage they refuse to fix — you can file a claim against the bond to recover your losses.

In Arizona, the ROC requires all licensed contractors to maintain a surety bond. The bond amount varies by license type:

• Residential contractors: $5,000 – $15,000
• Commercial contractors: $15,000 – $100,000+

The bond is not a substitute for a contract or a guarantee of quality — it is a financial backstop if things go seriously wrong.

• Poor workmanship (that is what your contract and warranty are for)
• Normal disputes about scope or timeline
• Damage caused by your own decisions or changes to the project

When a contractor says they are insured, they should carry at least two types of coverage:

This covers property damage and bodily injury caused by the contractor's work. If a plumber accidentally floods your basement, or a roofer drops a tool through your skylight, general liability pays for the damage.

Minimum coverage to look for: $1 million per occurrence for residential work.

This covers medical expenses and lost wages for the contractor's employees if they are injured on your property. Without workers' comp, an injured worker could sue you directly.

This is the one most homeowners overlook. If a contractor sends a crew of workers to your home and one of them falls off a ladder, workers' comp is what stands between you and a lawsuit.

Ask the contractor for a Certificate of Insurance (COI) — a one-page document from their insurance company listing their coverage types, limits, and policy expiration dates. Any legitimate contractor can produce this within a day.

For larger projects, ask to be listed as an additional insured on their policy. This means their insurance company will notify you if the policy lapses.

All four are important. A contractor who is licensed but not insured leaves you exposed. A contractor who is insured but not licensed may not know the applicable codes.

• "I do not need a license for this type of work" — verify this claim yourself at roc.az.gov before accepting it
• Reluctance to provide a COI — legitimate contractors have this ready
• Insurance that expired last month — always check the dates on the COI
• "I am covered under my employer's policy" — subcontractors often are not; ask for their own coverage
• Cash-only pricing with a big discount — often a sign of unlicensed, uninsured work

Every business listed on TrustedPro USA is sourced from public records and cross-referenced against the Arizona ROC database. Listings that display a "Verified" badge have had their license status confirmed as active at the time of verification.

That said, licenses can lapse. Always verify directly at roc.az.gov before signing a contract — especially for larger projects.
