What is the Arizona ROC license?
Answered by AskBaily Editorial · Updated
Short answer
The Arizona Registrar of Contractors (ROC) is the Arizona state agency that licenses all contractors. Residential contractors in Arizona must hold an active ROC license for any work exceeding $1,000 in labor and materials. License classes separate residential (B-, C-, K-, R- series) from commercial (A-, B-, and specialty). You can verify any Arizona license at ROC.az.gov.
In detail
Arizona is one of the few US states with a single, unified contractor licensing body that covers every trade. The Arizona Registrar of Contractors (ROC) administers:
- License classification — residential (R- and C- series for residential-only), commercial (A- series for general building), dual (B- series for both residential and commercial), and specialty (K- series for specific trades like electrical, plumbing, HVAC, roofing).
- Qualifying party — every ROC license has a Qualifying Party (QP) — a licensed individual on whose credentials the company license is built. If the QP leaves, the company has 60 days to replace them or the license becomes inactive.
- Bond requirement — residential contractors must carry a license bond ($4,200-$9,000 depending on volume) plus the ROC-administered Residential Recovery Fund (consumer protection) that pays homeowners up to $30,000 for bonded work that wasn't completed.
- Experience + testing — new QPs must demonstrate 4 years of trade experience plus pass trade and business-law exams.
Why ROC matters for Arizona homeowners:
- ROC.az.gov lets you look up any contractor's license status, complaint history, bond, and disciplinary history. Free, real-time.
- The Residential Recovery Fund is a specific protection — if a bonded ROC contractor takes your money and disappears, you can file a claim against the RRF for up to $30,000 in damages.
- Unlicensed contractors in Arizona face up to a Class 1 misdemeanor for the first offense and Class 6 felony on repeat.
- Contracts over $1,000 require a licensed contractor; accepting or paying an unlicensed contractor for over-threshold work voids most homeowner insurance coverage if the work fails.
Key license classes for homeowners to recognize:
- B- — general dual residential/commercial (can do whole-home remodels).
- C- or R- — residential-only specialties.
- K- — specialty trades (K-11 HVAC, K-34 residential remodeling, K-36 solar, etc.).
- CR- — commercial residential (only works on licensed residential).
