Arizona has one of the clearest statewide systems in the country through the Registrar of Contractors. For homeowners, that is good news: the ROC keeps contractor class, bond information, and complaint pathways in one place, so you can check whether a company is properly licensed for your exact type of project before signing.
How licensing works in Arizona
Arizona licenses contractors statewide and uses broad class groupings that matter to homeowners: Class A for engineering, Class B for general building, and Class C for specialty work. Most residential hiring falls under B or C classifications, and many companies hold multiple classifications. The ROC also ties licensing to bond requirements, which vary by classification and size. That means homeowners should look beyond licensed and confirm the contractor has the specific class that matches the planned work.
Project thresholds
Arizona generally requires a contractor license for jobs over $1,000, including labor and materials. Even below that amount, specialty trade rules and permit requirements can still matter.
What to verify in Arizona
Use the Arizona ROC search by license number, business name, or ROC number. Check that the license status is active and that the classification listed covers the work you need, such as residential general contracting or a specific trade. The ROC record can also show bond information, qualifying party details, and complaint history. If the scope includes multiple trades, confirm the company holds each needed classification instead of assuming one license covers them all.
State-specific tips
- › For a kitchen or bath remodel, verify both the main residential classification and any specialty licenses the company says it self-performs.
- › Read the bond section on the ROC record; Arizona makes that information unusually visible and useful for homeowners.
- › If a contractor says they can pull any permit, compare that claim to the exact classification codes on the ROC profile.
- › Use the complaint history as a screening tool, especially for roofing, pool, and solar jobs where consumer disputes are common.
- › Ask for the ROC number early; reputable Arizona contractors usually put it on proposals, vehicles, and ads.

Frequently Asked Questions
- What work requires a licensed contractor in Arizona?
- Any construction, alteration, or repair project with a combined labor and materials cost of $1,000 or more requires a contractor licensed by the Arizona Registrar of Contractors (ROC). This covers most home improvement work: additions, remodels, roofing, electrical, plumbing, HVAC, and pool work. Specialty trades require their own ROC license classification regardless of project size.
- What is the difference between bonded, licensed, and insured?
- Licensed means the contractor holds an active ROC credential verified against experience and financial requirements. Bonded means the contractor carries a surety bond required by the ROC — amounts vary by classification and provide limited recourse if work is incomplete or defective. Insured refers to general liability and workers' compensation; always request certificates and verify them independently.
- Is there a dollar threshold below which I don't need a licensed contractor in Arizona?
- Yes. Arizona generally requires a contractor license for projects over $1,000 in combined labor and materials. Below that amount work may proceed without a license, but specialty trade work — electrical, plumbing, HVAC — requires a licensed contractor regardless of project size. Even for smaller projects, pulling permits often requires a licensed contractor, so confirm with your local building department.
- Can I do my own home improvement work without a licensed contractor in Arizona?
- Yes. Arizona allows homeowners to perform work on their own primary residence without a contractor license. You must own and occupy the property; if you sell within two years of completion, disclosure of owner-built work to the buyer is required. The exemption does not apply if you are building for resale or using subcontractors to perform the work on your behalf.
- What license does a general contractor need in Arizona?
- The ROC issues licenses by classification. The most common for homeowners are the General Residential series (CR-license) for residential construction and General Commercial (KB) for commercial work. Specialty contractors hold classifications covering individual trades — electrical (C-11), plumbing (C-37), HVAC (C-39). Most home remodels involve a CR residential contractor or a combination of specialty trade licenses.
- How do I verify a contractor's license in Arizona?
- Use the ROC License Search at roc.az.gov. Search by license number, business name, or ROC number. Confirm the license is Active and that the classification covers your specific project type. The ROC record also shows bond information, complaint history, and the qualifying individual — review all of these before signing a contract.
- What does an active vs. inactive license mean in Arizona?
- An Active license means the contractor is in good standing with the ROC and legally authorized to perform work. An Inactive or suspended license means they cannot legally take on new work — often due to a lapsed bond or unresolved complaint. Treat any non-Active status the same as no license: do not hire and do not pay until Active status is confirmed.
- What insurance and bond does a licensed contractor need in Arizona?
- Bond requirements vary by license classification — residential contractors typically carry $5,000–$10,000. Contractors with employees must maintain workers' compensation insurance; those without employees may file an exemption. The ROC does not mandate general liability insurance, but always request a certificate and verify it remains active for the duration of your project.
- What happens if a contractor works without a license in Arizona?
- Performing contracting work without a valid ROC license is a Class 1 misdemeanor, punishable by fines and possible jail time. The ROC can issue cease-and-desist orders and civil penalties. Contracts with unlicensed contractors are generally unenforceable, limiting their ability to sue for unpaid work. Homeowners who knowingly hire an unlicensed contractor may lose some legal protections.
- My contractor's license expired mid-project — what now?
- An expired ROC license means the contractor is no longer legally authorized to perform work. Stop payments for any work performed after the expiration date and require renewal before continuing. Verify Active status on the ROC website before releasing further payments. If the contractor cannot or will not renew, you may have grounds to dispute payments for post-expiration work.
- Am I liable if an unlicensed worker gets hurt on my property in Arizona?
- Potentially yes. If a contractor has no workers' compensation insurance and an employee is injured, you could be held liable for medical costs and disability benefits as the de facto employer. This risk is eliminated by hiring a licensed contractor: ROC-licensed contractors with employees are required to carry workers' comp, verifiable through the ROC record before work begins.
- How do I file a complaint against a contractor in Arizona?
- File a complaint online with the Arizona Registrar of Contractors at roc.az.gov. The ROC investigates, can issue citations, order corrective work, and revoke or suspend licenses. For unlicensed contractor complaints, the ROC also has enforcement authority. File as early as possible — workmanship complaints are typically limited to two years from project completion.
