Contractor Licensing Requirements in Arizona

Arizona regulates contractors through a single statewide agency, the Registrar of Contractors (ROC), rather than city or county boards. Contractors choose from a detailed classification system covering general and specialty trades, split between residential and commercial designations, and must pass exams, prove experience, and secure a surety bond before the ROC will issue a license.

Arizona’s Contractor Licensing System

All contractor licensing in Arizona runs through the Arizona Registrar of Contractors (ROC), a state agency that reviews applications, administers the exam process, sets bonding requirements, and investigates complaints statewide. There is no separate city or county contractor licensing layer — a valid ROC license lets a contractor work anywhere in the state, though local jurisdictions still issue their own building permits.

License Classes in Arizona

• Licenses are split into Commercial and Residential designations, plus Dual licenses that cover both, based on the type of project work performed.
• General classifications include Commercial General (A/L-1) and Residential General (B/R) contractors who oversee whole-project construction, while dozens of Specialty classifications (C/CR series, e.g., electrical, plumbing, HVAC, roofing, flooring) cover single trades.
• Specialty classes are numbered (for example CR-11 electrical, CR-42 plumbing) and each requires its own qualifying party exam and experience showing competency in that specific trade.
• A Qualifying Party (a licensed individual tied to the license) must meet the experience and exam requirements for the specific classification the business is applying under.

Exam & Experience Requirements

Arizona requires a two-part exam for most classifications: a Statutes and Rules exam covering Arizona contractor law (administered through GMetrix) and a trade-specific competency exam through PSI. Applicants must also document at least four years of verifiable, relevant journeyman or supervisory-level experience in the classification requested within the last 10 years, unless that requirement is waived through reciprocity or an approved NASCLA exam.

NASCLA Reciprocity

Arizona is a NASCLA-participating state, so a contractor who already holds a NASCLA Accredited Examination score in a matching classification (such as Commercial Building or certain electrical/plumbing trades) can use that score to satisfy Arizona’s trade exam requirement instead of retesting, which speeds up licensing for contractors relocating from other NASCLA states.

Bonding & Insurance to Get Licensed

The ROC sets a required surety bond that varies by classification and projected annual volume — roughly $9,000–$15,000 for Residential General contractors, $4,250–$7,500 for Residential Specialty contractors, and $2,500–$100,000 for Commercial classifications depending on volume; residential contractors also contribute to the state’s Residential Recovery Fund. Applicants must additionally show proof of general liability coverage (and workers’ compensation where employees are used) as part of the licensing packet, though exact minimum coverage amounts are addressed elsewhere on this site.

Reciprocity with Other States

Beyond honoring NASCLA exam scores, Arizona does not maintain formal bilateral license-reciprocity agreements with other states — contractors moving from a non-NASCLA state generally still need to meet Arizona’s own exam and experience requirements for the classification sought.

Penalties for Unlicensed Contracting

Contracting without an Arizona license violates A.R.S. § 32-1151 and is prosecuted as a misdemeanor; under A.R.S. § 32-1153 an unlicensed contractor also forfeits the right to sue for payment on the job, and unlicensed contractors cannot record a valid mechanics lien under A.R.S. § 33-981.
