How Licensing Works in Colorado

Colorado does not operate a single statewide licensing regime for private security guards. Instead, security guard and related private security requirements are commonly imposed at the city or local level. Denver is a prominent example: the city maintains a formal security guard licensing process administered through its business licensing system.

Colorado also does not maintain an active statewide private investigator licensing program. The Code of Colorado Regulations lists the former private investigator licensure rules (4 CCR 750-1) as repealed (effective 01/14/2022). Legislative history around private investigator regulation includes vetoed or non-enacted measures, and the net effect for operators is that statewide PI licensure should not be assumed.

For multi-state operators, Colorado should be treated as a locality-driven compliance environment for guard services, with investigative services requiring careful confirmation of any applicable local licensing or other legal requirements in the specific jurisdiction where work is performed.

Operational Notes for Multi-State Firms

Colorado is best approached as a jurisdiction-by-jurisdiction problem. Firms should identify the specific city or locality where services will be performed (for example, Denver) and confirm local licensing requirements for both the company and personnel before deployment.
