The president's official residence and office is the Istana. However, no presidents since Yusof bin Ishak (1965–1970) have lived there. The current president, Halimah Yacob, had wanted to stay in the HDB flat at Yishun, but if she fails to comply with the security requirements, she will have to move out. She is also the first female President of Singapore and first Malay head of state in 47 years since the death of Mr Yusof bin Ishak who was Singapore's first president.
