Law enforcement in New York City

Members of New York city law enforcement agencies receive their powers and authority from New York State Criminal Procedure Law in one of two ways:

• as police officers, under Article 2, §1.20,
• as peace officers, under Article 2, §2.10, sub 25 and special patrolmen, under Article 2, §2.10 sub 27

Designation as a special patrolman is unique to New York City, and is granted by the Commissioner of the NYPD under section 14-106 of the New York City Administrative Code in conjunction with the New York State Criminal Procedure Law Article 2 Section 2.10 Sub 27, and are governed by protocols of Chapter 11 Title 38 of the Rules of the City of New York. This designation provides (non commissioned) private sector Public Safety officers limited authority as peace officers while on-duty only.

Privatized Public Safety Officers must complete the New York State POST (Peace Officer Standard of Training) to become certified.

There are at least sixteen City law enforcement agencies (including the FDNY Fire Marshals) and these are listed in the table below.
