Plumbing work can be complicated and difficult, and doing the work right is absolutely essential to the health and safety of our society.  Plumbers are generally licensed for just this reason — to ensure competency not only in the technical aspects of the job but the codes regulating the industry. Colorado has strict standards to accomplish this, beginning at the apprentice level.

According to the U.S. Bureau of Labor and Statistics, there are 442,870 plumbers nationwide and Colorado employs 10,440 of them. That number is projected to grow 4 percent from 2019 to 2029 across the country, but in Colorado according to CareerOneStop, the U.S. Department of Labor’s job search website, the projected growth rate is a whopping 38%.

And there’s more good news if you’re interested in this profession. The Associated General Contractors of America says contractors are hiring. In the 2020 AGC-Autodesk Workforce Survey, 60% of firms in the U.S. and 62% of firms in Colorado had unfilled hourly craft positions on June 30, 2020.

Licensing Requirements for Plumbers in Colorado

Is a license required for plumbers in Colorado? Yes.

It is illegal to perform any plumbing work except on your own home without a license in Colorado. To join this workforce legally, you must begin by registering as an apprentice. After two years of documented work under a licensed plumber, you can apply to get your residential plumbers license and after four years of documented work under a licensed plumber, you can apply to get your journeyman license. After five years total, you can apply to become a master plumber in Colorado.

Statewide regulations for electricians and plumbers are set by the Colorado Department of Regulatory Agencies (DORA) Division of Professions and Occupations. The Colorado State Plumbing Board falls under its purview and issues three plumbing license classifications and requires apprentice and contractor registrations.

Types of Plumbers Licenses in Colorado

What are the different types of plumbers licenses in Colorado?

You are required to register as an apprentice with DORA within 30 days of taking a plumbing job and your employer must “attach” your registration to the master plumber who will be supervising you and pay the $30 registration fee.

There are three levels of plumbing license in Colorado:

  • Residential — requires two years (3,400 hours) of practical experience.

  • Journeyman — requires four years (6,800 hours) of practical experience.

  • Master — requires five full-time years (8,500 hours) of practical experience.

One month of full-time experience is equivalent to 163 hours.

If you plan to be a general contractor you will need to get your license at the local level. The state does not regulate general contractor's licenses in Colorado. If you want to be a plumbing contractor, you must register with the state Plumbing Board.

Steps to Get a Plumber’s License in Colorado

  1. You must be at least 18 years old.

  2. Register as an apprentice. The State of Colorado defines an apprentice plumber as any person, other than a master, journeyman, or residential plumber, who, as his or her principal occupation, is engaged in learning and assisting in the installation of plumbing.

  3. To establish a record of apprenticeship, every apprentice plumber must be registered within 30 days of beginning work.

  4. After accumulating two years of experience as a registered apprentice, you may apply for a Residential Plumbers license and pay the licensing and exam fees.

  5. Or after accumulating four years of documented experience, you may apply for a Journeyman Plumbers license and pay the licensing and exam fees.

  6. After working for an additional year, thereby having five years total of work experience, you may apply for a Master Plumbers License and pay the licensing and exam fees.

  7. At each level you want to be licensed, you must take and pass a licensing examination to qualify for your license. You do not need to do them all, however. For instance, you can choose not to earn a residential license and continue as an apprentice until you qualify to test for the journeyman plumber license.

  8. Plumbers licenses expire February 28 of odd years and require eight hours of continuing education credits per year to be renewed.

  9. Felony convictions will not necessarily prevent you from becoming licensed but must be disclosed to the board with a full accounting of the events and current status and will be considered on a case-by-case basis.

  10. If you employ others, you must have workers compensation insurance and unemployment insurance and if you own your own business you must have at least basic coverage of $100,000 in property damage insurance and $300,000 in general liability insurance.

How to Get a Plumbers License in Colorado

EDUCATION/WORK EXPERIENCE: To get started on your plumbing career in Colorado, you can choose from a couple of paths. You can attend community college and earn an Associate Degree in Applied Science or complete a shorter certificate program at a technical college to get the foundational knowledge you need to get started. Employers often state a preference for candidates who have graduated from a relevant trade school or technical college because they have been educated in key skills needed for the job.

Alternately, you can opt for on-the-job training. There are hundreds of entry-level plumbing jobs in Colorado listed on job board sites like indeed and zip recruiter. Colorado requires anyone doing any kind of plumbing work to register first as an apprentice with the Department of Regulatory Agencies State Plumbing Board. You may then begin accruing the two years of experience needed as a plumbing apprentice under a licensed master plumber to apply to test for a Residential Plumbers License.

A Residential Plumbers license is for those individuals who plan to only install plumbing and equipment in one-, two-, three-, and four-family dwellings, no more than two stories above ground. If you want the freedom to work on commercial or projects other than those that fall under the strict residential definition or you want the opportunity to own your own plumbing business, you’ll need to continue to accrue more documented work experience.

Many employers will sponsor employees in an apprentice training program that typically lasts four to five years like those on the Colorado Registered Apprenticeship Program Directory website. That is also the required amount of time needed to gain the practical experience required to test for a Journeyman License (four years) or a Master License (five years).

APPLY TO TAKE LICENSE EXAM: After you’ve met the work experience requirements, you can apply to take the state licensing exam at your desired level. All three exams are administered by PSI testing services. If you pass, you will immediately receive a successful notification and should retain this notification to submit with your application for licensure.

APPLY FOR LICENSE: After successfully passing the exam, you can apply online for your Residential, Journeyman, or Master license. The Requirements for Individual Licenses are detailed here. For any of these license applications, you will need to submit a completed Affidavit of Experience, proof of citizenship, upload transcripts if applicable, answer general and criminal history screening questions and upload supporting documentation. You will also need to pay an application fee.

PROVIDE PROOF OF INSURANCE: If you wish to operate a plumbing contractor business, you will need to apply to register your company. This link provides an application checklist. If you employ others, you must have workers compensation insurance and unemployment insurance. If you are not a master plumber yourself, you will need to complete the Acknowledgement of Responsibility Form identifying the Master Plumber (MP) who will be responsible for all plumbing work performed.

The path begins with an apprenticeship, so you will be working and earning money from the start.

Colorado 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 many programs to get the training you need to become a plumbing professional in Colorado. You can choose to attend a community or technical college and earn a certificate or degree in plumbing. Emily Griffith Technical College offers a two-year plumbing degree that can satisfy one year of practical experience toward your licensing requirement.

But the path most often taken for a career in plumbing is an apprenticeship. Emily Griffith Technical College offers an apprenticeship path, too.  Also, as stated earlier, 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. Employers will often pay for the instruction if you maintain a certain grade point average. 

There are websites that can help:

Any program should also cover OSHA safety training, detailed instruction in chemistry, mathematics, physics, blueprint reading and drafting, in-depth examination of state codes, and advanced training about water treatment systems, water heaters, plumbing appliances, and plumbing fixtures.

Tuition: Apprenticeships usually have some up-front costs of tuition and book fees but the apprentice will be paid a percentage of the journeyman wage rate and will receive periodic wage increases as they meet program requirements.
