I assume that the Deputy is referring to the Commencement Order SI No. 206 of 2018, which commences provisions in Part V of the Housing (Miscellaneous Provisions) Act 2009.
Section 79(4) of the Housing (Miscellaneous Provisions) Act 2009 relates, in the first instance, to Sections 14 to 18 of the same Act, which require that each local authority make a Housing Services Plan. As Sections 14 to 18 were not previously commenced, Section 79(4) could therefore not be commenced.
While these provisions have not yet been commenced, it will not act as an impediment to the delivery of affordable housing by local authorities, driven by the substantially increased resources and new initiatives under Rebuilding Ireland.
