The Denver Police Department and Denver Excise and Licenses released comprehensive licensing requirements for Denver security guards in a press release Monday.

In Denver, to provide security services an individual must be employed by a private security employer licensed to operate in the City and County of Denver. Individuals must also possess a valid individual security guard license.

This comes after the city’s security requirements made national headlines when Matthew Dolloff, an unlicensed security guard, fatally shot a man at a Denver “Patriot Rally,” authorities say.

The departments said the release was an “educational effort to ensure all individuals and companies providing security guard services are operating in compliance with the law.”

“Education is a critical element for all of Denver’s required licenses,” said Ashley Kilroy, executive director of Excise and Licenses. “We’re determined to continue that educational effort, so the security guard industry and individuals are all complying with the law designed to improve public safety.”

Private security guards in Denver require an FBI background check, 16 hours of training and 8 hours of additional training annually before license renewal. Training covers security guard duties, communication protocols, interactions with law enforcement and use of force.

Additional license endorsements like carrying firearms or wearing plain clothes while on duty require further applications.

“Police recognize and value the role private security guard companies and their employees play in providing public safety services in Denver,” said Joe Montoya, DPD division chief. “It is our goal to work collaboratively with security providers while ensuring all security employers and individuals providing security services are doing so lawfully, and in the best interest of public safety and the citizens of the City and County of Denver.”

DPD assists Denver Excise and Licenses in reviewing security guard licensing applications.

These licensing requirements are applicable even if an individual is not called a security guard but still performs security duties.

The departments recommend that clients of security guard companies request proof of licensing for those providing security services.
