By the early 1940s was addressing the issue of subpar housing in Puerto Rico. A law passed in Puerto Rico in 1945 allowed housing agencies to clear slum areas (). One of the provisions of the US
Housing Act of 1949 did the same. As a result of the 1949 law, agencies in Puerto Rico sent plans for the construction of (housing) to Washington, DC for approval and by August 1952, the building of 9,890 new units across Puerto Rico had been authorized. Law 93-383 passed by the US Congress on August 22, 1974, for the improvement of residences, included Puerto Rico. The
Puerto Rico Department of Housing, created in 1972, succeeded the Urban Renewal and Housing Corporation, or (CRUV, its Spanish acronym), which was created in the late 1950s to succeed the Puerto Rico Housing Authority, created by Gov. Luis Muñoz Marín and headed by Juan César Cordero Dávila, to consolidate several state and municipal housing agencies. Puerto Rico Housing and CRUV were responsible for the design and construction of many of the older "residenciales" in Puerto Rico. The first three public housing developments, Ponce De Leon, Santiago Iglesias and Caribe, are located in the city of Ponce.
Henry Klumb provided early support for those efforts and one of his protégés, George McClintock was the first Architect-in-Chief of Puerto Rico Housing in the early-to-mid 1950s. Klumb's designs are the 1945 design work for the Cataño, San Lorenzo, Lares and Aguadilla Puerto Rico Housing projects, Naranjito Public Housing Project in 1957, Comerío Public Housing Project in 1958, and Residencial Las Virtudes, designed and built between 1969 ad 1976. Klumb had previously done work for several municipal housing agencies, including Mayagüez' and Ponce's. In 1973,
José Enrique Arrarás became the first Secretary of Housing. He was appointed by Gov.
Rafael Hernández Colón. In 1993, then governor
Pedro Rosselló had the
Puerto Rico National Guard doing security work at some of the public housing areas where crime, related to drug trafficking, was most prevalent. Since their construction, there have been many occasions when families are evicted en masse, and the buildings are demolished to make space for the erection of some new type of housing, that doesn't resemble
"public housing". ==Organization==
