City Tech's main campus grounds, the contiguous geographic perimeter of the main campus, the off- campus sites, the entry gates, and the parking areas are patrolled on a 24-hour basis by Public Safety Officers. Public Safety Officers are sworn law enforcement/NYS Peace Officers under Criminal Procedure Law 2.10 subsection 79 and have the power to make arrests in compliance with New York State Criminal Procedure Law Peace Officers Law. Public Safety Peace Officers receive training in accordance with the New York State Division of Criminal Justice Services (NYS DCJS). Officers also participate in continual in-service training to maintain state compliance. At City Tech, incidents of a criminal nature that are reported to a Peace Officer are referred, with the complainant's consent, to the NYPD. The Public Safety Department conducts administrative investigations involving CUNY policies, rules and regulations. These investigations may involve students, staff, and visitors on college property. Appropriate referrals necessitating further review and action may be made to the Student Affairs and/or Human Resources.

The Department consists of 1 Director, 2 Lieutenants, 6 Sergeants, 5 Specialists, 1 Locksmith and 23 Peace Officers (the latter are assigned to patrol the campus). Additionally, the College employs 17 Campus Security Assistants who are assigned to patrol and fixed posts; these officers are licensed as NYS Licensed Security Guards and do not have arrest powers (outside of the powers of a private citizen).

The Public Safety Department also oversees the electronic intrusion alarm system that protects various buildings and monitors approximately 440 security surveillance cameras to ensure the safety of the college community. Supplementing these campus security systems are Emergency Pull Boxes that have been installed in hallways and stairways.
