The Government’s  Housing For All – A New Housing Plan for Ireland  proposed a new tax to activate vacant land for residential purposes as a part of the Pathway to Increasing New Housing Supply. The Residential Zoned Land Tax was introduced by the  Finance Act 2021. 
The dataset contains the land identified as being covered by the tax from all of the local authorities in the state.  The available datasets will comprise the draft maps, published on 1 November 2022 and the supplemental maps, published on 1 May 2023.
The dataset will identify serviced land in cities, towns and villages which is residentially zoned and ‘vacant or idle’ mixed use land. The lands identified on the maps are considered capable of increasing housing supply as a consequence. 
Certain settlements will not be identified due to lack of capacity or services or due to out of date zonings. 
The dataset will also identify the amount in hectares of zoned serviced land for each settlement.
