Gerald Giam Yean Song requested data from the Minister for National Development on appeals for subsidised rental HDB flats from 2021 to 2023, including the number of appeals granted and the availability of more flats for married couples without children, elderly couples, and singles awaiting BTO flats. Desmond Lee responded that HDB does not have specific breakdowns for the appellants but highlighted that they have increased the supply of subsidised rental flats, notably doubling the provision under the Parenthood Provisional Housing Scheme (PPHS) from 800 to 2,000 units as demand surged during the COVID-19 pandemic. HDB has assisted 146 married couples without children, 72 elderly couples, and 211 singles with interim rental housing over the last three years, and while they can't provide flats to all applicants due to limited supply, they are prioritizing those with greater needs. Additionally, waiting times for BTO flats have been reduced, with over 80% of flats launched recently having waiting times of three-and-a-half years or less.
