The New York City Housing Authority Police Department was a law enforcement agency in New York City that existed from 1952 to 1995, which was then merged into the NYPD. The roots of this organization go back to 1934 and the creation of the New York City Housing Authority (NYCHA). New York City Mayor Fiorello H. La Guardia authorized the hiring of security guards to patrol the city's public housing buildings. These guards eventually were trained and became the first officers of the Housing Police, which was officially created in 1952. The Housing Police, along with the New York City Transit Police, was merged into the New York City Police Department in 1995 by New York City Mayor Rudolph W. Giuliani and continues today as the Housing Bureau.
