Taoiseach Leo Varadkar has warned there will be constraints in delivering the 67,000 potential homes on State-owned lands.
Social Democrats leader Holly Cairns said that it is "pathetic" that it has taken the Land Development Agency (LDA) five years to compile a report on the number of homes that could be built on land owned by the State.
The Report on Relevant Public Land, which was presented to Cabinet today identified 83 State-owned sites with the development potential for up to 67,000 affordable homes.
