Are you tired of hitting a ceiling in your plumbing career because you lack the official credentials to work independently? Navigating state licensing boards can feel overwhelming, but securing your credential is the key to higher pay and professional freedom. If you are wondering how to get a journeyman plumbing license in Colorado, you have come to the right place. This guide breaks down the process into simple, actionable steps so you can move from apprentice to licensed professional with confidence.
Colorado has specific requirements that differ from other states, making it crucial to follow the correct protocol. Whether you are moving from another state or finishing your apprenticeship locally, understanding the nuances of the Colorado State Plumbing Board regulations is essential. Let’s dive into what it takes to earn this valuable credential.
What Are the Basic Requirements for a Colorado Journeyman Plumber?
Before you can even think about scheduling an exam, you must ensure you meet the foundational eligibility criteria. The Colorado Department of Regulatory Agencies (DORA) and the State Plumbing Board have strict standards to ensure public safety and professional competence.
Experience and Education
The most critical requirement is hands-on experience. You cannot simply study your way to a journeyman license; you must prove you have done the work.
Apprenticeship Completion: You must complete a recognized apprenticeship program. Typically, this involves 4,000 to 8,000 hours of on-the-job training under the supervision of a master plumber.
Classroom Hours: Alongside fieldwork, you need approximately 288 to 576 hours of related technical instruction. This covers code study, blueprint reading, and safety protocols.
Timeframe: Most candidates spend between 2 to 4 years in an apprenticeship before qualifying for the journeyman level.
Age and Legal Status
You must be at least 18 years old.
You must have a valid Social Security Number or proof of legal presence in the United States.
You must not have any disqualifying criminal history that would pose a risk to public safety (though each case is reviewed individually).
Pro Tip: Keep detailed logs of your work hours. The State Plumbing Board may audit your experience verification. Having signed affidavits from your supervising Master Plumbers ready to go will save you weeks of delay.
How Do I Apply for the Journeyman Plumbing Exam?
Once you have met the experience requirements, the next step is applying for the examination. This process is administrative but requires precision. Mistakes here can lead to rejected applications and delayed testing dates.
Step 1: Gather Your Documentation
You will need to submit proof of your experience. This usually includes:
Verification of Experience Form: Signed by your employer or supervising Master Plumber.
Transcripts: Official records from your apprenticeship program or technical college.
Application Fee: As of 2026, the application fee is typically around $80–$100, but always check the current DORA fee schedule as it is subject to change.
Step 2: Submit the Application
Applications are submitted through the Colorado Online Licensing (COLA) system. Create an account, select “Plumbing,” and choose the “Journeyman Plumber” license type. Upload all required documents in PDF format. Ensure files are clear and legible.
Step 3: Wait for Approval
The board reviews applications within 2–4 weeks. If approved, you will receive an Authorization to Test (ATT) letter via email. Do not schedule your exam until you receive this letter.

What Is on the Colorado Journeyman Plumbing Exam?
Many candidates fail not because they lack skill, but because they are unprepared for the format of the exam. The Colorado Journeyman Plumbing Exam is designed to test your knowledge of codes, safety, and practical application.
Exam Format and Content
Provider: The exam is typically administered by PSI Services LLC or a similar third-party provider authorized by the state.
Question Type: Multiple-choice questions.
Duration: You usually have 3 to 4 hours to complete the exam.
Passing Score: A score of 70% or higher is generally required to pass.
Key Topics Covered
Colorado Plumbing Code: This is the most important section. You must know the specific amendments Colorado has made to the International Plumbing Code (IPC).
Safety Standards: OSHA regulations, trenching safety, and hazardous material handling.
Mathematics: Basic plumbing math, including pipe offset calculations, volume, and pressure tests.
Fixtures and Appliances: Installation requirements for water heaters, sinks, toilets, and gas lines.
Open Book vs. Closed Book
Check your specific ATT letter. Some jurisdictions allow codebooks during the exam, while others do not. If allowed, ensure your codebook is unmarked (no sticky notes, highlights, or handwritten notes) unless explicitly permitted.

FAQ: Common Questions About Colorado Plumbing Licenses
1. Can I transfer my plumbing license from another state to Colorado?
Colorado does not have universal reciprocity with all states. However, if you are licensed in a state with comparable standards, you may qualify for endorsement. You must still submit an application and provide proof of your current license and experience. In many cases, you will still need to take the Colorado-specific code exam.
2. Do I need a separate license to work on gas lines?
In Colorado, plumbing licenses generally cover gas fitting, but there are specific classifications. Ensure your journeyman license includes Gas Fitting privileges. If you only hold a water-supply plumbing license, you may need additional certification to work on natural gas or propane lines.
3. How long is the journeyman license valid?
Plumbing licenses in Colorado typically need to be renewed every three years. You must complete continuing education (CE) hours during each renewal cycle to stay compliant. Check your expiration date carefully to avoid late fees.
4. Can a Journeyman Plumber pull permits in Colorado?
Generally, no. Only a Master Plumber or a licensed contractor can pull permits for plumbing work. As a journeyman, you can perform the work, but the permit must be obtained by your employer or the Master Plumber overseeing the project.
5. What if I fail the exam?
If you fail, you can retake the exam. However, you must wait a specified period (usually 30 days) before retesting. You will also need to pay the exam fee again. Use this time to review your weak areas, particularly the Colorado-specific code amendments.
6. Is insurance required for a Journeyman Plumber?
While the state may not require personal liability insurance for a journeyman employee, it is highly recommended. If you plan to do side jobs or contract work, you must carry liability insurance. Additionally, your employer’s workers’ compensation insurance should cover you while on the job.
Conclusion
Earning your journeyman plumbing license in Colorado is a significant career milestone that validates your skills and opens doors to higher earnings and greater job security. By following the steps outlined above—verifying your experience, preparing thoroughly for the code exam, and navigating the DORA application process—you can achieve this goal efficiently.
Remember, the key to success is preparation. Don’t rush the study phase, especially when it comes to the specific Colorado Plumbing Code amendments. Your attention to detail now will pay off throughout your career.
