Data on new dwelling completions are published on a quarterly basis by the CSO. The data is disaggregated by local authority and dwelling type (i.e. apartment, multi-development house and one-off house) and can be accessed at https://data.cso.ie/table/NDQ06. Data on dwelling completions at a local area level can be accessed at https://data.cso.ie/table/NDQ09, though a breakdown per dwelling type per local electoral area is not available.
Separately, my Department publishes comprehensive programme-level statistics on a quarterly basis on affordable housing delivery activity in each local authority. Data for the period to end Q3 2024 can be accessed at the following link: www.gov.ie/en/collection/6060e-overall-social-housing-provision/
My Department also publishes the Social Housing Construction Status Report. The report details social housing developments, and their location, that have been completed, are under construction, or are progressing through the various stages of the design and tender processes. The latest report for Q3 2024 is available at: https://www.gov.ie/en/collection/cb885-social-housing-construction-projects-status-reports/
CSO dwelling completions data are not disaggregated by buyer type. That said, data on the number of homes purchased by different buyer types are published by the CSO, with data on new and existing homes purchased annually by non-household purchasers available at: https://data.cso.ie/table/HPA10
