Contractors in Colorado | ReadyDocs Compliance

Article I · State Baseline

Licensing sets the baseline. Local offices control the job.

Municipalities such as Denver and other local building departments control general contractor licensing, building permits, inspections, and local registrations.

Colorado does not issue one statewide general-contractor license. DORA regulates electrical and plumbing contractors at the state level, while general contractor licensing is mainly municipal.

Electrical and plumbing permits can route through DORA where state jurisdiction applies; general building permits usually route through the city or county.

Insurance and risk

Colorado employers with one or more employees must carry workers' compensation coverage.
