Active Master Plumber licences in Colorado

4,910 active licences carry this exact DORA type — the 33rd most numerous of the 92 with a page here, across 316 Colorado cities.

What this licence is

Master Plumber is one of the 204 licence types the Colorado Department of Regulatory Agencies issues, in the Plumbing family. Practising a regulated profession in Colorado without a current licence is unlawful, which is why DORA publishes this register for the public to check.

When this licence has to be renewed

DORA renews this type on a two year cycle , in odd years, with the licence expiring on 31-Aug. That date is the same for everyone holding it — which is why 4,910 renewals fall due together every August.

DORA publishes this in a 344-row table of codes. It is not published anywhere as a calendar. The whole calendar, month by month.

164 of the 4,910 active licences of this type carry a disciplinary action in DORA's file — 3.3%.

This site publishes that count and no more: never who, and never a case number. DORA records the type of action and no reason at all, and the two most common entries statewide are a stipulation and a letter of admonition — agreed outcomes. Every licence counted here is active. Why that line is drawn there.
