Getting your Colorado license starts here...
In Colorado, there is no single statewide general contractor license issued at the state level. Instead, contractor licensing is handled primarily by local municipalities and counties. For example, cities like Denver, Colorado Springs, and Aurora maintain their own licensing requirements for general, building, electrical, mechanical, and plumbing contractors. Electrical and plumbing contractors, however, are licensed and regulated statewide through the Colorado Electrical Board and Colorado Plumbing Board, both part of the Department of Regulatory Agencies (DORA).
Typical requirements include proof of experience, passing trade exams, liability insurance, and surety bonds, depending on the jurisdiction and license type.
Contractor Licensing Inc. simplifies the Colorado process. With more than 18 years of experience, our family-run team helps contractors navigate city and state requirements, prepare for trade exams, and obtain the right bonds and insurance so projects can move forward without delay.

Electrical Individual Licenses
Individual licenses for electricians (Master, Journeyman, Residential) including exams, verified experience, and continuing education.

Company license to contract for plumbing work. Requires employing a master plumber and meeting board insurance/administrative criteria.
Master / Journeyman / Residential (State)
Plumbing Individual Licenses
Individual licenses for plumbers (Master, Journeyman, Residential). Experience verification and exam typically required.
Note: Other trades (HVAC, mechanical, roofing, gasfitting, etc.) are typically licensed or registered by
municipalities rather than at the state level.

Specialty Trades (Local)
Low-voltage (non-power limited), fire alarm/suppression, and similar specialties are typically city-licensed/registered.
Bond Requirements
Colorado has no universal statewide contractor license bond for general contracting.

Public works may require project bonds (bid, performance, payment).
