The Living Space Improvement Transfer Scheme (LSITS) introduced in 2005 provides more opportunities for public rental housing (PRH) tenants to improve their living conditions. All PRH households with a living density (in terms of internal floor area) below 7 square metres per person are eligible. Tenants who are eligible for the Territory-wide Overcrowding Relief Transfer Exercise (i.e. households with a living space below 5.5 square metres per person) can also apply for the LSITS and enjoy priority in flat selection in view of their more pressing need.
