How to check a Colorado plumber's license
Colorado licenses plumbers at the state level through the Department of Regulatory Agencies (DORA) and its State Plumbing Board. Individual plumbers hold master, journeyman or residential licenses, and a plumbing business registers as a Plumbing Contractor, which must have a licensed master plumber responsible for its work. DORA's license lookup shows whether a contractor registration is active; a status such as "Need Master Hire" means the company cannot practice until it has one.
Colorado has no statewide general contractor license, so cities such as Denver run their own contractor licensing and permits. Ask your plumber whether the job needs a city permit.
Before you hire
- Look up the company on DORA's license lookup and confirm the Plumbing Contractor registration is active.
- Ask who the responsible master plumber is.
- Ask whether the work needs a city permit.
- Get a written estimate.
