The National Housing Authority (NHA) is the sole national agency mandated to engage in housing production for low income families. It traces its roots to the People's Homesite Corporation (PHC), the first government housing agency established on 14 October 1938 and to the National Housing Commission (NHC) which was created seven years later, on 17 September 1945. These two agencies, the PHC and the NHC, were eventually merged on 4 October 1947 into the People's Homesite and Housing Corporation (PHHC).
In the years that followed, six(6) more housing agencies were created to respond to separate and distinct shelter requirements, namely: the Presidential Assistant on Housing and Resettlement Agency (PAHRA); the Tondo Foreshore Development Authority (TFDA); the Central Institute for the Training and Relocation of Urban Squatters (CITRUS); the Presidential Committee for Housing and Urban Resettlement (PRECHUR); the Sapang Palay Development Committee (SPDC); the Inter-Agency task Force to Undertake the Relocation of Families in Barrio Nabacaan, Villanueva, Misamis Oriental. Eventually, on 15 October 1975, the National Housing Authority was organized as a government-owned and-controlled corporation, by virtue of Presidential Decree No. 757 dated 31 July 1975. All other housing agencies were abolished by the said decree. The NHA took over and integrated the functions of the abolished agencies - the PHHC and the six (6) other housing agencies. The creation of the NHA is the second attempt of the government to integrate all housing efforts under a single agency, twenty-eight years after the merger under the PHHC.
Three years later, the Ministry of Human Settlements (MHS) was created in 1978. The Ministry adopted the wholistic approach to housing. The NHA was placed as an attached agency to the MHS.
On 26 March 1986, Executive Order No. 10 was issued placing the NHA as well as the other agencies attached to the abolished MHS, under the administrative supervision of the office of the President. Subsequently, Executive Order No. 90 was issued on 17 December 1986, rationalizing the housing structure in the government along lines of specialization and concentration.
EO 90 identified the key housing agencies to implement the National Shelter Program and defined their respective mandates. The NHA was mandated to be the sole government agency to engage in housing production. Under the said Executive Order, NHA was placed under the policy and program supervision of the Housing and Urban Development Coordinating Council (HUDCC), the umbrella agency for shelter charged with the main function of coordinating the activities of various government housing agencies engaged in production, finance and regulation.
Executive Order No. 20 on 28 May 2001 reaffirmed mass housing as a centerpiece program in the poverty alleviation efforts of government. Said EO likewise reaffirmed HUDCC's administrative supervision over the housing agencies including the NHA.
