Council's must rectify problems such as mould, heating issues or damaged windows before the unit can be re-allocated.
Less than a third of maintenance requests are being carried out however, which a local councillor says is adding to the delays.
Councillor Shane Moynihan hopes this national plan will help get tenants back into these houses sooner.
"In this overall pot of funding, there is €40 million for local authorities across the country to get those houses back into use.
"What is interesting is that South Dublin County Council has the second largest allocation of all the local authorities nationally, so there's just over €2 million available to South Dublin County Council to draw down to try and bring down the number of voids that it has and to get them back into use."
Mr Moynihan added that the number of disused houses in the area is about 100.
Elsewhere, plans have been lodged to build an apartment block as tall as Liberty Hall in Ringsend, Co Dublin.
The project involves knocking down one and two storey buildings on the site on York Road and replacing them with 48 apartments over 15 storeys.
The developer has also applied for an exemption from providing 10% social housing.
A number of locals are opposing the plans saying the development is "out of character" with the area.
