Arizona Plumber Licensing FAQs

Who needs to be licensed in Arizona?

Any business which contracts or offers to contract to build, alter, repair, add to, subtract from, improve, move, wreck or demolish any building, highway, road, railroad, excavation or other structure, development or improvement, or to do any part of the work must be a licensed contractor.

Also included in work requiring a license is the erection of scaffolding, connections to utility service lines, metering devices and sewer lines, mechanical or structural service to a structure or improvement and any other work in connection with the project.

“Contractor” includes subcontractors, floor covering contractors, hardscape contractors and consultants representing themselves as having the ability to supervise or manage a construction project for the benefit of the property owner.

Supervision or management includes hiring and firing of specialty contractors, scheduling of work on the project, and selection and purchasing of construction material.

Contractors must be properly licensed before submitting bids.

The plumbing industry is often changing. As a professional plumber, it is important to keep your industry knowledge up to date so you can make practical decisions for your business. Professional development courses are designed to help you sustain and improve your plumbing industry knowledge.

Whether you are looking for information on new avenues for your business, want to brush up on best practices, or are just interested in learning about a particular topic, professional development is for you!

No. Unlike continuing education, which is required by your licensing body to maintain your license, professional development is not required and is considered supplemental learning.

You may begin immediately! Simply click the Login button in the upper right-hand corner on your desktop or in the upper-right menu on mobile. Once you've entered your login and password, you will be taken to your courses. Follow the instructions and enjoy!

Our courses are available online, 24/7, and you can log in and log out at any time during the course. If you are going to be away from your computer for more than 10–15 minutes, we recommend that you log out. When you log back in, you will be able to re-enter the lesson you were last in.

Continuing education requirements vary by state. Each course lists a minimum number of credit hours required to complete the course.

It depends on your learning style and comfort level with the topics we cover. There is no set time for completing exam prep courses — you go at your own pace!

Many plumbers like to re-watch materials, while others like to re-take the practice tests. Our recommendation is to go through the course as many times as you need to be comfortable with the material and any applicable reference books. The more familiar you are with the materials, the better you will do on your exam!

After you purchase a course, you have unlimited access for six months. If you need additional time, please contact our offices to arrange an extension (please note: a fee may apply).

It depends on course type and location. Most continuing education courses include quizzes.

Exam prep courses have a short quiz at the end of each lesson and a longer practice test at the end of the course. These quizzes and tests are there to help you practice taking an exam and identify areas you may wish to review more.

No. Practice tests are just that: for practice. You will have the opportunity to retake the practice tests until you do pass. The practice tests are there to help you get used to the process of using your reference materials and finding the correct answers during an exam. If you don't pass on the first try, take the time to note what sections of the material you need to review.

You can review the lessons and quizzes at any time during the six months you have access to the courses.
