"Public housing" is often used as a generic term to refer to all publicly assisted housing, but the term "public housing" actually refers to a specific federal program. Created in 1937, the low-rent public housing program was the first major federal rental housing assistance program. The program initially subsidized the construction, and later the ongoing operation and maintenance, of multifamily rental housing properties for low-income families. While public housing is a federally created and funded program, the properties are owned and managed at the local level by quasi-governmental public housing authorities (PHAs) under contract with the federal government. Given this unique federal-local relationship, the program is governed in part by federal rules and regulations and in part by policies set at the local level.
