Arizona Contractor License Guide: Exams, Classifications, and How to Prepare

If you want to work as a licensed contractor in Arizona, understanding the license types and exams is the first big step. Arizona has one of the most detailed contractor licensing systems in the country, with separate classifications for residential, commercial, and dual licenses. Each classification comes with its own exam requirements, scope of work, and business rules. That can feel overwhelming at first, especially if you are new to the process.

This guide breaks down the most common Arizona contractor license classifications and explains what each one covers in plain language. You will learn what kind of work each license allows, who typically needs it, and how exam preparation fits into the process. Whether you are aiming for a general contractor license or a specialized trade, the goal here is to help you feel confident and informed.

All Arizona contractor licenses are regulated by the Arizona Registrar of Contractors, often called the ROC. The ROC sets the rules for exams, experience, bonding, and ongoing compliance. Using the right study tools and understanding your classification can save you time, money, and frustration as you move toward becoming licensed.

A-11/R-17 (CR-17) Steel and Aluminum Erection (Commercial and Residential)

The A-11 and R-17 steel and aluminum erection license allows contractors to install and erect structural and non structural steel or aluminum components. This includes frames, beams, columns, and related assemblies used in both commercial and residential construction. Contractors with this license often work on buildings, carports, shade structures, and specialty frameworks.

Because steel and aluminum erection involves safety critical work, the exam focuses heavily on plans, specifications, and job site safety. You will also be tested on Arizona business law and contracting rules. Preparing for this exam requires both trade knowledge and a solid understanding of state regulations.

If you are planning to focus on metal structures, this license is a strong foundation. Many contractors use exam prep tools from 1 Exam Prep CR-17 study materials to review calculations, codes, and safety topics before testing.

A-19 Swimming Pools, including Solar (Commercial) and B-6 General Swimming Pool

The A-19 swimming pool license covers the construction and installation of commercial swimming pools, including solar heating systems. This license is commonly used by contractors working on hotels, community pools, and large facilities. The B-6 license is closely related and often paired for broader pool work.

The exam emphasizes hydraulics, circulation systems, electrical bonding, and safety barriers. Solar pool heating adds another layer, requiring knowledge of panels, controls, and energy efficiency. Business management and Arizona statutes are also part of the test.

Contractors preparing for this license often benefit from targeted exam prep. Resources like A-19 swimming pool exam prep can help you review both pool construction and solar concepts.

A-9 Swimming Pools (Commercial) and B-5 General Swimming Pool (Residential)

The A-9 and B-5 swimming pool licenses separate commercial and residential pool work. A-9 focuses on larger, public use pools, while B-5 is designed for backyard and residential installations. Together, they cover excavation, structural shells, plumbing, and pool finishes.

These exams test your understanding of pool layout, equipment installation, and safety standards. Residential pools may seem simpler, but Arizona still requires strict compliance with fencing, drains, and electrical bonding rules. Business law remains a key part of the exam.

Many pool contractors start with residential work and later add commercial licensing. Study guides such as B-5 pool exam prep can help build confidence before test day.

Arizona C-37 (CR-37) Plumbing (Commercial)

The C-37 plumbing license allows contractors to install, repair, and modify plumbing systems in commercial buildings. This includes water supply, drainage, venting, and related fixtures. Commercial plumbing often involves larger systems and stricter code requirements.

The exam covers the Uniform Plumbing Code, sizing calculations, and system design. You will also be tested on safety practices and Arizona contracting law. A strong understanding of code tables is especially important.

Plumbers often rely on structured study programs like CR-37 plumbing exam prep to stay focused and organized while studying.

B General Residential Contractor and B-2 General Small Commercial

The B General Residential Contractor license allows you to build and remodel entire residential structures. The B-2 General Small Commercial license expands that scope to include smaller commercial buildings. These licenses are popular because they offer broad flexibility.

The exams test knowledge across multiple trades, including framing, roofing, electrical basics, and project management. Business law, estimating, and contract requirements are also major components. Preparation takes time because of the wide range of topics.

Many candidates choose comprehensive prep tools such as general contractor exam prep to cover both trade and business sections.
