How to Verify a Contractor\'s License in Arizona (ROC Lookup Guide)
Before hiring any contractor in Arizona, you can verify their license in 60 seconds at roc.az.gov. Here is exactly what to check — and what the results mean.
How to Verify a Contractor's License in Arizona (ROC Lookup Guide)
Hiring an unlicensed contractor in Arizona is one of the most common — and most expensive — mistakes homeowners make. Unlicensed contractors aren't bonded, aren't insured, and aren't accountable to any regulatory body. If something goes wrong, you have almost no recourse.
The good news: verifying a contractor's license takes about 60 seconds and is completely free. Here's exactly how to do it.
What Is the Arizona ROC?
The Arizona Registrar of Contractors (ROC) is the state agency that licenses and regulates contractors in Arizona. Any contractor performing work valued at $1,000 or more — including labor and materials — is required by law to hold an active ROC license.
The ROC maintains a public database of all licensed contractors, including their license status, license type, complaint history, and bond information. It's one of the most useful consumer protection tools available to Arizona homeowners.
How to Look Up a Contractor's License
Step 1: Go to roc.az.gov
Step 2: Click "License Search" in the navigation
Step 3: Search by:
- License number (the fastest method — ask the contractor for it)
- Business name
- Owner name
Step 4: Review the results
The search takes about 30 seconds. If a contractor can't give you their license number, that's a red flag.
What to Look For in the Results
Once you find the contractor's record, here's what each field means:
License Status
- Active — the contractor is currently licensed and in good standing. This is what you want to see.
- Inactive — the license has lapsed. The contractor cannot legally perform work in Arizona.
- Suspended — the license has been suspended, often due to unresolved complaints or failure to pay a judgment. Do not hire.
- Revoked — the license has been permanently revoked. Do not hire.
License Classification Arizona contractor licenses are classified by trade. Common classifications include:
- B-1 General Residential Contractor — can perform most residential construction and remodeling
- B-2 General Small Commercial Contractor — commercial work under certain thresholds
- C-11 Electrical — licensed electrician
- C-37 Air Conditioning and Refrigeration — HVAC
- C-34 Plumbing — licensed plumber
- CR-39 Roofing — licensed roofer
Make sure the license classification matches the work being performed. A plumber with a C-34 license shouldn't be doing electrical work.
Expiration Date Verify the license is current. A license that expired last month is not valid.
Bond Information Licensed contractors in Arizona are required to be bonded. The bond protects you if the contractor fails to complete the work or causes damage. Verify the bond is active.
Complaint History This is the most important section. The ROC database shows:
- Number of complaints filed against the contractor
- Whether complaints were resolved
- Whether any judgments were issued
A contractor with 1–2 resolved complaints over many years isn't necessarily a problem — complaints happen in any trade. But a pattern of unresolved complaints or multiple judgments is a serious warning sign.
What If a Contractor Isn't in the Database?
If you search for a contractor and can't find them, there are a few possibilities:
- They're unlicensed — the most common reason. Do not hire them for any work over $1,000.
- They gave you the wrong name — try searching by owner name or business name variations.
- They're a subcontractor — some specialty trades work as subs under a general contractor's license. Ask who holds the license of record for your project.
If a contractor claims they don't need a license for your project, verify this independently. The threshold is $1,000 in combined labor and materials — most home service jobs exceed this.
What to Do If a Contractor Is Unlicensed
Don't hire them. The risks are significant:
- No bond means no protection if they damage your property
- No insurance means you could be liable if a worker is injured on your property
- No ROC oversight means no recourse if the work is substandard
- Unlicensed work may not pass inspection, creating problems when you sell
If you've already been victimized by an unlicensed contractor, you can:
- File a complaint with the Arizona Attorney General's Consumer Protection Division at azag.gov/consumer
- Report the unlicensed contractor to the ROC at roc.az.gov/complaints
- Consult an attorney about civil remedies
The 60-Second Pre-Hire Checklist
Before signing any contract with an Arizona contractor:
- Look up their ROC license at roc.az.gov — confirm it's Active
- Verify the license classification matches the work
- Check the complaint history
- Ask for proof of general liability insurance (separate from the ROC bond)
- Get the license number in writing on the contract
This takes less than 5 minutes and can save you thousands of dollars.
