Statistics in relation to vacant social housing homes are compiled by the National Oversight and Audit Commission (NOAC) in its annual reports on Performance Indicators in Local Authorities. These statistics are set out on a local authority basis and include the percentage of total local authority dwellings that were vacant at the time of the review by NOAC, with the most recent report relating to 2017. This report is available on the NOAC website at the following link: http://noac.ie/wp-content/uploads/2018/09/NOAC-Performance-Indicators-Report-2017.pdf.
It should be noted that my Department does not hold information on the number of vacant or void local authority houses at any point in time. Local authorities, however, are actively encouraged to ensure that all vacant properties are brought back into active use as expeditiously as possible. While my Department provides exchequer funding to local authorities to support eligible capital improvements to local authority housing, including through the Voids and Energy Efficiency Programmes, section 58 of the Housing Act 1966 provides that the management and maintenance of local authority housing stock is a matter for each individual local authority in the first instance. This includes the implementation of planned maintenance programmes and carrying out of responsive and pre-letting repairs. It is a matter for the local authority, in this case Dublin City Council, to manage the maintenance and subsequent allocation of their properties.
In relation to Dublin City Council, I understand that it maintains a list of unoccupied local authority properties and provides specific information on these properties to Elected Representatives and on a regular basis at its monthly meetings and Area Committee meetings.
