One of the functions of the Approved Housing Bodies Regulatory Authority (AHBRA) is to collect and publish information (including statistical information on the number of dwellings in AHB ownership) concerning AHBs as it considers necessary and appropriate. Statistics on overall units owned, managed or leased by AHBs are captured as part of the AHBRA annual monitoring programme. AHBRA commenced its third monitoring programme in October 2024, the results of which were published in its latest Sectoral Analysis in July 2025, and is available on their website www.ahbregulator.ie/app/uploads/2025/07/AHBRA-Sectoral-Analysis-Insights-from-the-2024-AHB-Monitoring-Programme.pdf
AHBRA also categorise AHB’s by size based on the number of dwellings owned. While this is not broken down by individually named AHB, the information on the number of AHBs in each category, small/medium/large/Care and Support, is also available in their published sectorial analysis.
Data on the numbers of housing units owned by individual bodies would be available from the AHBs directly. Local Authorities also hold a breadth of information on the AHB dwellings they have funded, in each LA area.
