• The Hong Kong Housing Authority (HA) is a statutory body established in April
1973 under the Hong Kong Housing Ordinance. The Housing Department is
HA’s executive arm.
• HA develops and implements a public housing programme to meet the housing
needs of people who cannot afford private housing.
• Approximately 30% of the Hong Kong population is now living in public rental
housing units.
• The HA has an existing stock of about 730,000 rental flats.
• We build 79,000 new PRH flats for five years from 2012/13 to 2016/17 and
build 100,000 new PRH flats for the five years starting from 2018.
• We build 17,000 new HOS flats for four years from 2016/17 to 2019/20 and
thereafter 5,000 new HOS flats a year.
