article 45 of the Constitution prohibited the Chief of State from occupying a residence on properties held by the State. A loophole in the document allowed the authorization on 28 June 1912 of a government edict to rent an annex alongside the Palace for 100,000 réis per month to house the first President Manuel de Arriaga, who eventually preferred to live in his local residence and work at the palace. This policy of renting the space continued throughout the period of the First Republic. After the assassination of President Sidónio Pais in 1918 at the Rossio railway station, the ex-President's body lay in state in the Sala Luís XV (Luís XV Hall) until his burial. The official residency law for the President of the Republic was promulgated on 24 March 1928. It specified that the President and his family would be permitted to reside in one of the national palaces.

In 1967, the property was finally classified as an IIP - Imóvel de Interesse Público (Property of Public Interest), by decree 47-508, published in the Diário do Governo on 24 January 1967. The Palace was closed in 1969 to repair damage from the earthquake of that year. After the Carnation Revolution, the palace was made the headquarters of the Junta de Salvação Nacional (National Salvation Junta). It also experienced the traumas of the new democracy with the counter-revolutionary attempts by António Spínola and Francisco da Costa Gomes. As in previous administrations, Belém Palace underwent new renovations in the Arrábida wing in order to accommodate the demands of the President and his family. While some Presidents resided in Belém, others such as Mário Soares, Jorge Sampaio, Aníbal Cavaco Silva and the current President Marcelo Rebelo de Sousa used it merely as a workplace, living in their private residences during their terms. Between 1980 and 1985, the
