Illinois Private Security and Private Investigation Licensing Guide

Illinois regulates private security and private investigation under 225 ILCS 447 through IDFPR. The system combines (1) agency licensure for firms operating as private security contractors and private detective agencies, (2) individual licensing for certain regulated roles defined in the Act, and (3) employee registration through the Permanent Employee Registration Card (PERC) process for many individuals employed in covered security-related positions.

For private security services, the Act establishes licensure for private security contractor agencies and contemplates a continuing requirement for an Illinois licensed private security licensee-in-charge as part of agency licensure. Individuals working in covered roles commonly must obtain a PERC, which serves as evidence of eligibility for employment in regulated positions under the Act and rules.

For private investigation, the Act establishes licensure for private detective agencies and private detectives. Depending on role and function, individuals may be subject to individual licensure requirements under the Act, and employees in covered positions may also require PERC registration.

Operationally, Illinois should be treated as an IDFPR-administered regime where agency licensure and individual authorization can be a mix of licensure and PERC registration depending on the exact service line and role.

Illinois requires careful role mapping. Firms should plan for agency licensure plus individual authorization that may include PERC registration and, where required by the Act, individual licensure (including licensee-in-charge requirements for agency licensure). Role definitions in 225 ILCS 447 and associated rules drive the correct compliance path.
