Starting a career in the trades is one of the most rewarding financial decisions you can make, but navigating the bureaucratic hurdles can feel overwhelming. If you are eager to start working under a master plumber but aren’t sure where to begin, you are not alone. Many aspiring tradesmen get stuck on the initial paperwork, wondering specifically how to get an apprentice plumbing license in Colorado without wasting time or money.
The good news? Colorado has streamlined this process significantly compared to other states. You don’t need to pass a difficult exam to start learning; you simply need to register correctly. This guide will walk you through every step, from eligibility to submitting your application to the Department of Regulatory Agencies (DORA), ensuring you hit the ground running on your new career path.
Understanding the Colorado Plumbing Licensing Structure
Before we dive into the application process, it is crucial to understand where an “Apprentice” fits into the Colorado plumbing hierarchy. Unlike some states that require you to find a mentor before you can register, Colorado allows you to register as an apprentice first. However, you cannot work independently.
According to the Colorado Revised Statutes regarding plumbing, all plumbing work must be performed under the supervision of a licensed Journeyman or Master Plumber. Your license is essentially a permit that allows you to legally learn the trade while on the job. It is the foundational step toward becoming a Journeyman and eventually a Master Plumber.
Why Register as an Apprentice?
- Legal Compliance: Working without registration can lead to fines for both you and your employer.
- Hour Tracking: Your time as a registered apprentice counts toward the hours required for your Journeyman exam.
- Portability: Having a state-registered license makes it easier to prove your experience if you move or change employers.

Step-by-Step Guide: How to Get Your License
Getting your apprentice license in Colorado is primarily an administrative process rather than an academic one. Follow these concrete steps to ensure your application is approved quickly.
1. Meet the Basic Eligibility Requirements
Colorado keeps the barrier to entry low to encourage workforce development. To qualify, you must:
- Be at least 18 years old.
- Have a valid Social Security Number (SSN) or Individual Taxpayer Identification Number (ITIN).
- Be employed by or have an offer of employment from a licensed Plumbing Contractor.
Note: You do not need a high school diploma or GED to register as an apprentice, though many employers prefer it.
2. Create an Account with Colorado DORA
The Division of Professions and Occupations (DORA) handles all plumbing licenses. You will need to create an online account via their licensing portal.
- Visit the Colorado DORA Online Services website.
- Select “Create an Account.”
- Verify your email address to activate your profile.
3. Complete the Apprentice Application
Once logged in, navigate to the “Plumbing” section and select “Apply for New License.” Choose Apprentice Plumber as the license type.
You will be asked to provide:
- Personal identification details.
- Your employer’s license number (this is critical; you must be sponsored by a licensed contractor).
- Payment information for the application fee.
4. Pay the Application Fee
As of the latest fee schedule, the cost for an initial Apprentice Plumber license is $80.
- Renewal Fee: $60 (every two years).
- Late Renewal Fee: Additional penalties apply if you miss the renewal window.
Pro Tip: Always double-check the current fee schedule on the DORA website, as state fees can adjust annually based on legislative changes.
5. Receive Your License Number
After submission, processing times typically range from 2 to 4 weeks. However, many applications are processed faster if all information is correct. Once approved, you will receive your license number via email. You must carry proof of this license (digital or physical copy) while on any job site.
Key Requirements and Responsibilities
Having the license is just the beginning. To maintain your status and progress in your career, you must adhere to specific responsibilities.
Supervision is Mandatory
You are not allowed to pull permits or design plumbing systems. All work you perform must be supervised by a Journeyman or Master Plumber who is present on the job site or directly overseeing your work.
Tracking Your Hours
To advance from an Apprentice to a Journeyman Plumber in Colorado, you must complete 4,000 hours of on-the-job training.
- Keep a Log: Do not rely on your employer to remember your hours. Keep a personal digital or physical log of every hour worked.
- Verification: When you apply for your Journeyman exam, you will need your employer(s) to verify these hours. Discrepancies here are the #1 reason for delayed upgrades.
Continuing Education (For Future Levels)
While apprentices do not currently have mandatory continuing education (CE) requirements in Colorado, Journeymen and Masters do. It is wise to start building good habits now by attending optional workshops or safety courses.
Common Mistakes to Avoid
Even with a straightforward process, applicants often stumble. Here are the most frequent errors:
| Mistake | Consequence | Solution |
|---|---|---|
| Incorrect Employer License # | Application rejected or delayed. | Ask your boss for their exact license number before applying. |
| Working Without Registration | Fines up to $500+ per violation. | Wait until you have your license number in hand before starting work. |
| Losing Hour Logs | Cannot upgrade to Journeyman. | Use a cloud-based app or spreadsheet to back up your hours monthly. |
| Missing Renewal Date | License expires; illegal to work. | Set a calendar reminder 30 days before your expiration date. |
Frequently Asked Questions (FAQ)
1. Do I need to take a test to become an apprentice plumber in Colorado?
No. There is no examination required for the Apprentice Plumber license. The exam is only required when you upgrade to a Journeyman or Master Plumber license. The apprentice level is purely for registration and tracking purposes.
2. Can I work as an apprentice without being employed by a licensed contractor?
No. You must be employed by or under the direct supervision of a licensed Plumbing Contractor. You cannot freelance or perform independent plumbing work as an apprentice.
3. How long does it take to get my apprentice license after applying?
Typically, the Colorado DORA processes applications within 2 to 4 weeks. If you submit incomplete information or fail to pay the correct fee, it will take longer. Ensure your employer’s license number is active and correct to avoid delays.
4. Does my apprentice license expire?
Yes. All plumbing licenses in Colorado, including apprentices, must be renewed every two years. Make sure to renew before the expiration date to avoid late fees or having to reapply as a new applicant.
5. Can I transfer my apprentice hours from another state?
Colorado may accept out-of-state experience, but it is evaluated on a case-by-case basis. You will need to provide verified documentation of your hours and the scope of work performed. Contact DORA directly for a transcript evaluation if you are moving from another state.
6. What is the difference between an Apprentice and a Journeyman?
An Apprentice is learning the trade and must be supervised. A Journeyman has passed the state exam, completed 4,000 hours of training, and can work independently under the umbrella of a licensed contractor, but cannot pull permits for their own business. A Master Plumber can run their own business and pull permits.
Conclusion
Learning how to get an apprentice plumbing license in Colorado is the first vital step toward a lucrative and stable career in the skilled trades. By following the steps outlined above—verifying your eligibility, securing employment with a licensed contractor, and registering through DORA—you can legally begin your journey in just a few weeks.
Remember, this license is more than just a piece of paper; it is your ticket to gaining the 4,000 hours of experience needed to become a Journeyman. Stay organized, keep detailed records of your work hours, and always prioritize safety and code compliance.
