Arizona Plumbing License: Everything You Need to Know

The plumbing industry in Arizona is thriving, with opportunities for contractors and skilled tradespeople to work on both residential and commercial projects. Arizona’s licensing system is focused on plumbing contractors, while Journeyman and Apprentice Plumbers follow local regulations. This guide will help you navigate licensing  requirements, insurance, renewals, and career pathways in Arizona.

What plumbing work can be done without a license?

In Arizona, Journeyman and Apprentice Plumbers are not required to hold state-issued licenses, but they must comply with local ordinances and work under the supervision of licensed contractors. Minor plumbing repairs and basic maintenance can often be performed by unlicensed individuals, but larger projects, such as pipe installations and system overhauls, require a licensed plumbing contractor.

What are the different types of plumbing licenses available in Arizona?

Arizona issues licenses for Residential, Commercial, and Dual (Residential and Commercial) Plumbing Contractors. These licenses are regulated by the Arizona Registrar of Contractors (ROC) and are required for projects exceeding $1,000 or involving work that requires a permit.

Residential Plumbing Contractor License (C-37R)

• Requirements: Pass the trade and business exams and demonstrate at least four years of plumbing experience.
• Scope of Work: Perform plumbing installations, repairs, and maintenance for single-family homes and residential properties.

Commercial Plumbing Contractor License (C-37)

Dual Plumbing Contractor License (C-77)

• Requirements: Meet the qualifications for both Residential and Commercial licenses.
• Scope of Work: Work on plumbing projects for both residential and commercial properties.

Contractors must also provide proof of liability insurance, bonding, and pass background checks to obtain a license.

How to get a plumbing license in Arizona

Arizona’s process for obtaining a plumbing contractor license is designed to ensure candidates have the necessary experience, knowledge, and financial protections in place to operate safely and effectively.

Step 1: Verify Eligibility

To qualify for a plumbing contractor license in Arizona, candidates must demonstrate a minimum of four years (or 8,000 hours) of plumbing experience. This experience can include time spent as an Apprentice or Journeyman working under a licensed contractor. Examples of qualifying experience include:

• Residential or commercial plumbing system installations.
• Maintenance and repair of existing plumbing systems.
• Supervisory experience on plumbing projects.

Candidates must compile documentation to verify their experience, such as:

• Employer references.
• Affidavits of completed work.
• Detailed project descriptions and timelines.

Step 2: Submit an Application

Applications are submitted through the Arizona Registrar of Contractors (ROC). The application must include:

• Personal and business details (e.g., name, address, and contact information).
• Verification of four years of plumbing experience.
• Payment of the application fee, typically around $580 (subject to change based on license type and ROC updates).

Applications can be submitted online or in person, and the ROC provides detailed instructions and checklists to ensure candidates include all required materials.

Step 3: Pass Required Exams

Applicants are required to pass two exams administered by an ROC-approved testing center:

1. Business Management Exam: This test evaluates knowledge of Arizona laws, contract management, and financial practices. Key topics include:
   • Arizona Registrar of Contractors rules.
   • Business ethics and risk management.
   • Employee and workplace safety regulations.
2. Trade Exam: Focused on technical plumbing knowledge, this exam covers:
   • State plumbing codes and compliance.
   • System design and layouts.
   • Installation and repair best practices.

Preparation resources, such as study guides and practice exams, are available through the ROC and independent providers.

Step 4: Obtain Insurance and Bonding

Licensed plumbing contractors in Arizona must carry both liability insurance and a surety bond to protect against financial losses and legal claims. The minimum coverage amounts are:

• Residential Contractors: $200,000 aggregate liability coverage.

Contractors must submit proof of insurance and bonding as part of their final application. Many insurance providers specialize in coverage for contractors, offering tailored policies that meet Arizona’s requirements.

Once all requirements are met, the ROC will issue the license. Licensed contractors are then authorized to:
