Before 1974, what is today Subang Jaya was part of Klang District. Development on Subang Jaya began on 21 February 1976 and was concluded in 1988 by Sime UEP Properties Berhad, the property development arm of the Malaysian conglomerate Sime Darby. The site was formerly a rubber plantation called Seafield Estate under the municipality of Petaling Jaya. Upon completion of Subang Jaya in the same year, Sime UEP began clearing land for the development of USJ. In 1999, Sime UEP began the development of Putra Heights which is located on the southern end of Subang Jaya.

In 1997, Subang Jaya received the status of a municipality, elevating the Petaling District Council to Subang Jaya Municipal Council. The municipal comprise the areas administered by the former Petaling District Council, as well as some areas transferred from Petaling Jaya, Puchong and Shah Alam. This means that the MPSJ municipal holds local government authority not only in the Subang Jaya city centre, but also USJ, Putra Heights, Batu Tiga, Bandar Sunway, Puchong, Bandar Kinrara, Seri Kembangan, and Balakong. In parliamentary terms, Subang Jaya's municipal area covers the parliamentary constituency of Puchong and Subang in its entirety, as well as parts of Kota Raja which mainly cover Putra Heights. On the west side of Subang Jaya, covers areas like Subang Hi-Tech Industrial Park, Taman Mutiara Subang, Taman Subang Mas and Tropicana Metropark. Subang Jaya city itself lies within the Subang constituency, while Seri Kembangan and Puchong fall within the Puchong constituency. In Dec 2019, it was officially announced that Subang Jaya's municipality will be upgraded to a city council after a long 5-year wait since MPSJ's application in 2014.
