The evidence indicates that there is clear justification for Inner West Council to actively seek to increase the supply of affordable housing through its planning instruments and policies. This is related to the large, disproportionate and growing number of local people in housing stress; the displacement of historical populations through ongoing gentrification and non-replacement of affordable housing lost; current and projected levels of unmet need for affordable housing including for very low, low and moderate income households together with other more vulnerable groups; and the amount of unearned land increment (land value uplift) created through the operation of Council’s planning and approvals processes, some of which may reasonably be contributed to affordable housing as key infrastructure or a public purpose under a voluntary planning agreement or other legal mechanism. Housing is generally considered to be ‘affordable’ when households that are renting or purchasing are able to meet their housing costs and still have sufficient income to pay for other basic needs such as food, clothing, transport, medical care and education. ‘Affordable housing’ has a statutory definition under the NSW Environmental Planning and Assessment Act 1979 (NSW), being housing for very low, low or moderate income households, where ‘very low-income’ households as those on less than 50% of median household income; ‘low-income’ households’ as those on 50-80% of median household income, and ‘moderate income’ households as those on 80-120% of median household income for Sydney SD.
