This web service depicts the location and quantity of all lands zoned for residential or primarily residential purposes in statutory local authority development plans and local area plans across Ireland.The then Department of Environment, Community and Local Government, in conjunction with Local Authority Planning Departments, carried out a national survey of all lands zoned for residential or primarily residential purposes in statutory local authority development plans and local area plans across Ireland in order to determine the location and quantity of lands that may be regarded as being undeveloped and available for residential development as of the 31st March 2014. The project was undertaken in two stages. Stage 1: Local Authorities identified the total level of undeveloped lands that were residentially zoned as of the 31st of March 2014, regardless of the sequence of the development of those lands or phasing under local authority development plan core strategies. Stage 2: Local Authorities identified from the parcels of land identified in Stage 1 those lands which were potentially available for development in relation to the order or priority or phasing indicated under the relevant Development or Local Area Plan period. Essentially, the difference between stage 1 and stage 2 is that stage 1 totalled all undeveloped lands zoned for residential development, while stage 2 broke the stage 1 figures into the amount of land that could be developed under the phasing schedule of the relevant plans.This data is also available on the MyPlan map viewer at https://viewer.myplan.ie.Background and context to this data is in the Summary Report available here: https://www.housing.gov.ie/planning/residential-land-availability/residential-land-availability-survey-2014
