You can’t rush through the training it takes to become a plumber, but that time and effort can lead to a career that is long-lasting, lucrative, and fulfilling. Almost every state requires plumbers to be licensed because it’s complicated work that impacts the health and safety of our society.
According to the U.S. Bureau of Labor Statistics, there are 504,500 plumbers nationwide, and Arizona employs 12,330 of them. The national number is projected to grow 6% from 2024 to 2034, adding more than 43,300 plumbers to the ranks across the country. In Arizona, according to CareerOneStop, the U.S. Department of Labor’s job search website, the projected growth rate is more than double that at 14% for Plumbers, Pipefitters, and Steamfitters.
Contractors struggle to find skilled tradesmen like plumbers, electricians, and HVACR or mechanical professionals while the demand for them continues to grow. According to the Associated General Contractors of America, “Construction employment in Arizona in July 2025 totaled 223,500, an increase of 1,100 (0.5%) from July 2024 and an increase of 47,700 or 27% from February 2020.” So, if you get the training you need, you should have a variety of jobs to choose from when you’re ready.

The Arizona Registrar of Contractors offers free virtual monthly Applicant Education Seminars to help you navigate the process and answer any questions. They also have a step-by-step guide on “Applying for a License” on the website.
APPRENTICESHIP/WORK EXPERIENCE: You could begin with an apprenticeship that will combine hands-on training with classroom instruction and usually takes four to five years.

The Qualifying Party must meet or exceed the license classification requirements for the license for which they are applying.
The License Classification Requirements form provides the minimum number of years of experience and the types of examinations required for a Qualifying Party to be eligible for a specific license classification. For the plumbing licenses, that’s four years and both the Statutes and Rules Exam and the Trade Exam.
TAKE LICENSING EXAM: The Qualifying Party must pass the required examinations by at least 70% and submit the exam results. The Qualifying Party must complete the AZ SRE Statutes and Rules Exam as well as a specific trade exam, unless eligible for a waiver.
BACKGROUND CHECK: The Applicant and Qualifying Party must submit copies of the payment transaction receipt from their background checks. Click here to learn more and to submit a background check.
FORM LEGAL ENTITY: In Arizona, a license may be issued to a sole proprietorship (individual), a partnership, limited liability company or a corporation.

Arizona Plumber Training Programs and Schools
Plumbers are responsible for a lot more than just fixing leaks or clogs. They design, install, and renovate systems that carry liquids or gasses, so they must know more than just the mechanics. They must know plumbing code. There are quite a few colleges in Arizona that offer plumbing programs, as well as many other training programs to get the training you need to become a licensed plumber. You can choose to attend a community or technical college and earn a certificate or degree in plumbing.
Here are two detailed lists of the best Plumbing colleges and universities in Arizona:
Niche: 2025 Best Colleges with Plumbing Degrees in Arizona
Universities.com: Best Plumbing Technology Plumber Colleges in Arizona 2025
Many of the certificate programs are specifically designed to give students the base knowledge they need to prepare them for an entry-level position. Many employers hiring entry-level plumbers helpers follow an apprentice model—pairing new employees with others who are licensed to begin hands-on training while requiring the beginner to attend classes if they have not already done so. Employers will also often pay for instruction if you maintain a certain grade point average.
Arizona Western College offers a 60-credit Associate of Applied Science in Plumbing degree that typically takes two years to complete. The in-state tuition for the program would be about $6,000. The Construction Trades program at Gateway Community College is also designed to help students thinking about a career in plumbing, electrical, HVAC, carpentry, or construction management.
Apprenticeship: There are also several apprenticeship opportunities to get the training you need in Arizona. The Union Apprenticeship offered through UA Local 649 is five years long, consisting of 10 semesters. Each semester costs $520. The expectation is that the students work during the day and attend classes twice a week in the evenings. Those outside of the greater Phoenix area may have the option of attending class on Saturday. Apprentices in the program typically take their code license exam near the end of their fifth year. The pay is a portion of the journeyman wage and increases each year.
Arizona’s Department of Economic Security also maintains a website of Registered Apprenticeships that meet national standards for registration with the U.S. Department of Labor. Apprenticeships through the Department of Labor are recognized nationwide, so your credentials will move with you. Or you can simply look for an entry-level position on Indeed or ZipRecruiter or another job board and work for a licensed contractor to learn on the job.
Program Prerequisites: For any of these paths, you need to be at least 18 years old and have a high school diploma or a GED (General Educational Development) degree.
On-the-Job Experience: While on the job, you will need to have good customer service skills, be detail-oriented, have some mechanical capability, and be physically fit because the job can include some heavy lifting and hours of walking, standing, and working in tight spaces.

Who Issues Plumbing Contractors Licenses in Arizona?
Plumbing licenses are issued through the Arizona Registrar of Contractors (ROC). Some of Arizona’s cities license at the journeyman level as well. Be sure to check with local governments where you intend to work to make sure you meet any additional licensing or permitting requirements.
Does My Arizona Plumbing Contractors License Work in Any Other State?
Arizona has reciprocity agreements with California, Nevada, and Utah, allowing plumbers to potentially bypass some licensing requirements in those states.
What Are the Reciprocity Requirements for a Plumbing License in Arizona?
Plumbing contractors with licenses in other states with comparable licensing requirements may apply for a waiver. The Registrar may decide a trade exam is not required if the qualifying party has been the qualifying party within the preceding five years for a license in good standing in the same classification in this state, or a classification the Registrar deems comparable in another state. The AZ SRE Statutes and Rules Exam cannot be waived because it has reference to Arizona-specific statutes and rules.
Plumbing Certifications
Other certifications can help you demonstrate your proficiency to potential employers and clients. National Inspection Testing and Certification (NITC), International Association of Plumbing and Mechanical Officials (ASSE Certifications) and other professional certifications are not required but may make you a more attractive hire to prospective employers or can increase your marketability to customers.
Other Requirements Unique to Arizona
While the state does not license apprentices or issue journeyman plumber licenses, some of Arizona’s cities do license at the apprentice and journeyman level so you always want to check with the jurisdiction where you intend to work to make sure you’re following any local requirements. For instance, the city of Phoenix licenses plumbing professionals as journeyman or apprentices as described in the building code.
Are There Plumbing Scholarships in Arizona?
Yes, there are plumbing scholarships available in Arizona. Several organizations offer financial aid to students pursuing plumbing and related trades, including the PHCC Educational Foundation and Arizona Construction Trades.
PHCC scholarships are available to students in an approved apprenticeship program or college/trade school program throughout the state. Arizona Construction Trades (ACT) scholarships are available to Pima Community College students pursuing the trades.
In addition to this scholarship, plumbing students in Arizona can explore financial aid opportunities by completing the Free Application for Federal Student Aid (FAFSA). Submitting the FAFSA gives you access to federal grants like the Pell Grant, subsidized student loans, and work-study programs—all of which can help cover tuition, tools, and other training costs. Many Arizona community colleges and trade programs also use FAFSA data to award institutional aid or state-based grants.
How Can Someone Verify My Plumbing License in Arizona?
Your plumbing license can be verified by potential clients or employees in Arizona through the Arizona Registrar of Contractors. One of the online services on the website is a Contractor Search, where anyone can verify the status of a license. Users can search by name or license number. In addition, the state maintains a list of current contractors, pending applications, and disciplinary actions.
When Can a Plumbing License Be Suspended in Arizona?
A suspended license means that the plumber is temporarily prohibited from practicing their trade legally. Some of the common reasons that an Arizona plumbing license can be suspended are:
Fraud
Professional incompetence
Misleading or deceptive practices
Criminal convictions
Aiding unlicensed individuals
Failure to comply with regulations
Practicing on a lapsed license
Willful or repeated violations of regulations governing plumbing professionals
Note: The information above should not be considered legal advice. For detailed and specific information about Arizona plumbing license regulations you can refer to the official Arizona Statutes, Rules, and Policies.
What Are the Penalties for Unlicensed Plumbing Work in Arizona?
Performing plumbing work in Arizona without a license is illegal. Unlicensed contracting is a Class 1 misdemeanor, with a minimum penalty for first-time offenders of $1,000 fine. The maximum penalty can include up to six months in county jail and a maximum fine of $2,500 plus surcharge. For repeat offenses, the minimum fine increases to at least $2,000.
In addition, if an unlicensed entity bids on a $1,000+ contract, they cannot become legally licensed until a year after that bid date.
