CT Private Investigator (Private Detective) License: Requirements, Fees, and Forms [2026]

Requirements last verified: August 3, 2026 • Last checked: 2026-08-03

In Connecticut, the statutory credential is a Private Detective (individual) or Private Detective Agency (business) license under Chapter 534 of the Connecticut General Statutes. The day-to-day investigator role is titled “private investigator” and is an employee registration under a licensed agency—not an independent state license. See the definitions and scope in CGS Chapter 534 and DESPP Special Licensing & Firearms Unit (SLFU) guidance.
