Colorado Contractor License & Regulatory Intelligence

Snapshot metrics

Research a Colorado electrical or plumbing contractor registration

Public business identity is CO-DORA:{prefix}:{number}. This lookup covers EC and PC business registrations only. Individual electricians, plumbers, apprentices, architects, and engineers are not contractor-business profiles.

Market findings

• Colorado does not issue a statewide general-contractor license. DORA statewide contractor-business evidence is electrical contractor (EC) and plumbing contractor (PC) registration. Absence from EC/PC is not proof that a general contractor is unlicensed — general contracting is primarily local.
• Active EC registrations 4,789 and Active PC registrations 3,147 are separate specialty credential populations. They are not additive unique companies. Combined they are electrical + plumbing contractor credential rows, not “Colorado contractors.”
• The DORA master extract has 1,606,852 license rows across 313 prefixes. That file includes nurses, pharmacists, and other professions. It is not a contractor universe.
• Contractor-relevant prefixes carry 5,990 discipline observations and 5,198 distinct case numbers. Attach only with licensePrefix + licenseNumber. Name-only is unsafe. A discipline row is not a unique case. A case is not a criminal conviction.
• Professional engineer, architect, land surveyor, and landscape architect licenses are statewide professional credentials. They are not general contractors, construction businesses, or proof of project performance.

Regulatory map

Model CO_DORA_SPECIALTY_NOT_GC. Primary regulator: Colorado Division of Professions and Occupations (DORA). Statewide electrical and plumbing contractor registration plus individual trade and AELS professional licenses. Does not issue a statewide general-contractor license. Source: CIM dataset 7s5z-vewr.

Identity CO-DORA:{licensePrefix}:{licenseNumber}. licenseNumber alone is not globally unique.

Electrical and plumbing contractor businesses

EC is a business registration (4,789 Active of 12,495 rows). PC is a business registration (3,147 Active of 5,415 rows). EC is not ME. PC is not MP. 784 normalized names hold more than one EC/PC credential.

Individual trades and AELS

Master/journeyman/residential electrician and plumber licenses are person-grain research evidence. They do not automatically create public person profiles. Apprentice records (APE, AP) are internal. Professional engineer, architect, land surveyor, and landscape architect licenses are not general contractors and are not construction businesses.

Discipline

Contractor-relevant prefixes have 5,990 observation rows and 5,198 distinct case numbers. Attach only with exact licensePrefix + licenseNumber. Name-only is unsafe. A discipline row is not a unique case. A case is not a criminal conviction. No action found is not a clean record. The full DORA file has 59,624 flagged rows across all professions — do not call that a contractor discipline count.

What the sources do not establish

• Bond/insurance bulk evidence: UNKNOWN / NOT_ACQUIRED. Missing is not zero.
• Statewide building permits were not identified. Denver was not ingested. Permits are local/AHJ.
• Public works / debarment: VERIFY / SEARCH / REQUEST. Do not claim zero debarred contractors.
• Secretary of State entities were not ingested in this ticket. Name-only SOS joins are unsafe.
