In California, you must register as a plumber when you first start your official apprenticeship training.

This does not grant you a license or a certification; it simply means the state knows of your intent to become a plumber.

Once you start your training you are an apprentice, whether you are officially in an apprenticeship yet or not.

From there, you must complete training hours through an apprenticeship or trade school (or a combination of the two).

Once initial training is complete, you can then register as a journeyman. This entails changing your status from apprentice to journeyman and passing the Business & Trade exam as well as the plumbing license exam.

Once you have board approval to sit for the exams and pass them, you will be a journeyman plumber. This allows you to work on non-bid plumbing jobs (value of labor and materials less than $500) and gain the needed experience and training to become a master plumber.

How To Become A Master Plumber in California

The next step after journeyman is to become a licensed master plumber. In California, a master plumber is known as a plumbing contractor. To become a master plumber, you must pass the exams. However, before you are qualified to even sit for the exams, you must meet the minimum criteria.

  • First, you must be over 18 and have a valid California driver’s license and high school diploma (or GED).
  • Be able to show legal ability to work in the US.
  • Have a minimum of 4 years experience as a journeyman plumber.
  • Must be able to show a minimum of $2500 working capital.
  • Must file a bond with the state registrar in the amount of at least $10,000.
  • Pass a thorough legal, criminal, and financial background.

The journeyman experience can also be as a contractor, owner-builder, or job foreman. Once this criteria is met, you can then sit for the plumbing C-36 exams. After passing the exams (70% or higher), you will be licensed as a plumbing contractor and can begin working on biddable jobs over $500 in value.

Quick Guide in Choosing Your Plumbing Trade School

Before you can become a master plumber, you must start at the bottom. That means getting the education you need to start your new career. Choosing the best plumbing trade school, though, can be more of a challenge than it seems. To help, the following factors should be thoroughly considered and figured out.


The school’s location should be the right distance from either your home or current job place. Keep in mind the time of day or night when classes start, distance to travel, and traffic when you will be on the road.

However, just because a school is close to you doesn't mean it is the best overall option. There may be a better school that meets more of your needs a few extra miles up the road.

Accredited/Authorized School

Every higher education institution needs to apply for accreditation. This process proves to the accrediting bodies they offer a minimum level of education and meet certain expectations regarding staffing, tuition, class sizes, and other things.

Without accreditation, your certificate, training or diploma may not mean anything. For example, most colleges won't accept credits for transition if the school they come from isn't accredited. If you plan to find a decent job or further your education towards a degree, school accreditation is a must.

Offers Quality Education

Beyond the minimum education standards set for accreditation, you need to make sure the education quality is something that suits your needs, specifically. The best method is to visit the campus in person and talk to current students and staff.

Figuring out how current persons feel about the school, what texts or computer software is being used to teach, and how the labs are handled, will go a long way to helping you make your final decision.

Offers Hands-on Training

As with all trades, plumbing education must have lab time or hands-on training. Some schools will limit the lab hours when you are also in an active apprenticeship, as the job will give you hands-on training.

However, as a minimum standard, your school should offer at least 50% of the course as lab hours. If you find a school that offers less than half of the course to the lab, you may want to find a different school.

Connects you to an Apprenticeship/Internship Program

Part of your journey to master plumber requires going through an apprenticeship. Many schools offer post-graduation programs that help you find jobs and apprenticeships.

This free service will help you gather needed forms and paperwork, fill out applications, and get ready for interviews. It is an invaluable service that you should take full advantage of.

Offers Customer Service Skills Training

As a plumber, you will work closely with customers on a daily basis. It is important to know how to communicate effectively and handle adverse situations. If you don’t have any prior customer service experience or training, ensure the school you choose offers at least one class on the subject.


The cost of tuition is only going to rise. You want to ensure you can afford the school. This may entail the use of scholarships, grants, or even financial aid. Before you can use these programs, though, you need to make sure the school accepts them.

Some schools may not accept outside forms of payment, though. This is usually because the courses or classes are shorter and cost much less than a full-tuition course.

Full course-load classes, though, will last at least 12 months and can cost up to $8000. You also have the option to attend a college course through a community or state college. Those fees will depend on the type of course and if it is a certification course or a degree-granting curriculum.

Inn-state students will pay lower fees, but it will still be the same as all other credit-hour classes based on semester and availability. These courses range from about $6000 to $9000 for a certification course, through $30,000 for a degree in the construction trades.
