Antipolo was converted from a municipality into a component city of Rizal Province on April 4, 1998, under Republic Act No. 8508.[7] A new provincial capitol building was inaugurated in the city in March 2009 to replace the old capitol in Pasig, which has long been outside the jurisdiction of Rizal Province, since Pasig was included in Metro Manila in 1975. With the transfer of the provincial government to Antipolo, it is highly favored to be officially designated as the new capital of the province.[8] On March 14, 2011, Antipolo was declared according to Proclamation No. 124 s. 2011 a highly-urbanized city by then President Benigno S. Aquino; however, the proclamation has yet to be ratified in a plebiscite.[9] Pending a plebiscite, Antipolo is the most populated city in the Philippines under a component city status. On June 19, 2020, President Rodrigo Duterte signed Republic Act 11475, designating Antipolo City as the official capital of Rizal Province.[10] It took effect on July 7, 2020.
