Private Detectives

Connecticut General Statue 29-153, requires that any person or firm wishing to conduct business as a Private Detective Service in this state, must first obtain a professional license from the Commissioner of Emergency Services and Public Protection. Guidelines for obtaining the license, eligibility criteria, and applicable license fees are detailed in the statute. Private Detective services are also required to register all employees working as investigators under their license. The Special Licensing & Firearms Unit (SLFU) is responsible for processing the license applications and employee registrations, as well as investigating complaints concerning violations of the license statutes.

No license shall be issued to any person who has been convicted of any felony, (2) convicted of any misdemeanor under section 21a-279, 53a-58, 53a-61, 53a-61a, 53a-62, 53a-63, 53a-96, 53a-175, 53a-176, 53a-178 or 53a-181d, or equivalent conviction in another jurisdiction, within the past seven years, (3) convicted of any offense involving moral turpitude, or (4) discharged from military service under conditions that demonstrate questionable moral character.

It does not grant a general investigation license.

No license may be granted to an applicant currently vested with police powers.
