Colorado Plumber License Reinstatement: Deadlines, CE, and Re-Examination

Letting a Colorado plumber license expire doesn't necessarily mean starting over — but the window for a straightforward reinstatement closes faster than most people expect. The difference between a simple renewal with a late fee and having to retake the state exam comes down to exactly how long your license has been inactive.

The 60-Day Grace Period

For the first 60 days after your license expires, you're in the grace period. During this window, you can renew by paying the standard renewal fee ($18 per cycle) plus a delinquency fee. No reinstatement application is needed during this period.

This is the lowest-friction path back to active status. If your license just expired and you're reading this within two months, handle it now. The process gets progressively harder with each threshold you cross.

Expired 60 Days to 3 Years: Reinstatement Application

Once you've passed the 60-day grace period but haven't yet hit the three-year mark, DORA requires a formal reinstatement process:

1. File a reinstatement application through the MyLicense Office portal
2. Pay the reinstatement fee (separate from and in addition to the renewal fee)
3. Prove you've completed at least 8 hours of continuing education since your last valid renewal

The CE requirement is the key distinction from the grace period. You need to show that you've maintained some level of current competency, even if your license wasn't active. The 8 hours must come from Board-approved providers. Confirm with DORA how the code-focused requirement applies to your reinstatement period.

During this period, you cannot legally perform plumbing work — your license is expired, not suspended. Working on a job site with an expired license is a violation that can result in disciplinary action and potentially affect your reinstatement application.

Expired More Than 3 Years: Re-Examination Required

This is the threshold that changes everything. If your license has been expired or inactive for more than three years, the reinstatement pathway is closed. You cannot reinstate through paperwork and CE alone.

Instead, you must:

1. Re-register for the state plumbing exam through PSI Services
2. Pay the exam fee ($75–$78 for the initial attempt)
3. Pass the exam with the required score for your license tier (70% for residential or journeyworker, 75% for master)
4. Submit a new license application to DORA with your passing score report

You do need to demonstrate current competency through the exam, because plumbing codes evolve and the Board requires proof that you're current with the adopted standards. Do not assume that previously documented hours automatically carry into a post-three-year application; follow DORA's current instructions for any experience documentation it requires.

The exam itself covers the International Plumbing Code, International Fuel Gas Code, and State Plumbing Board Rules. If significant code changes have occurred since you were last active — and given that Colorado is transitioning to three-year renewal cycles and has adopted updated IPC editions — there will likely be material that's new to you.

Why the 3-Year Line Matters So Much

The gap between "reinstatement with CE" and "full re-examination" is enormous in terms of time, cost, and effort. Consider the practical difference:

At 2 years and 11 months expired: File the reinstatement application, pay the fee, complete 8 hours of CE, and you're back to active status. Total timeline: days to a few weeks.

At 3 years and 1 day expired: Schedule a PSI exam (book 4–6 weeks in advance), study for and pass the exam, submit a new DORA application, and wait for processing. Total timeline: two to four months, minimum.

If your license is approaching the three-year mark and you're uncertain about reinstating, the math strongly favors acting now. Even if you're not planning to work immediately, reinstating your license while you're still in the CE-only window preserves your credential without the exam requirement.

The 2027 Cycle Change

Starting March 1, 2027, Colorado extends license renewal cycles from two years to three years. This doesn't change the reinstatement thresholds (the 60-day grace period and three-year re-exam line remain the same), but it does affect how the CE accumulation works during active cycles.

Under the new three-year cycle, active licensees need 24 hours of CE per cycle (still 8 per year). For reinstatement purposes, the key question remains: have you completed the required CE hours since your last valid renewal? If not, that's the first thing to address.

Protecting Your License Going Forward

Once reinstated, the simplest way to avoid going through this process again:

• Complete your 8 hours of CE annually during the March 1–February 28 licensure year, not in a last-minute rush before renewal
• Set a calendar reminder 90 days before your renewal deadline — DORA opens the renewal window well before expiration
• Keep your CE certificates — DORA conducts random audits, and you'll need to produce documentation if selected

The Colorado Plumber License Guide includes a Renewal and CE Tracker that maps each licensure year's requirements and deadlines — designed to prevent exactly the kind of lapse that triggers the reinstatement process.
