Mr Cai Yinzhou asked the Minister for National Development (a) of the HDB public rental flats that are occupied, how many are currently approved to have air-conditioning units installed; (b) what are the common grounds on which such requests have been approved; and (c) what is the average waiting time for HDB to approve a rental flat tenant's request for air-conditioning installation.

Mr Chee Hong Tat: As of August 2025, about 7,000 public rental flats had air conditioners installed. The Housing and Development Board will take into consideration tenants' circumstances, including medical grounds, in assessing each application. Approvals for air conditioner installation are usually issued within two weeks, if the proposed installation complies with the technical guidelines.
