Largest Residential Applications, Last Two Years

Applications for 20 or more homes received since 21 September 2024, largest first, where the number of homes can be read from the register. Some applications do not state it in a form that can be read, so the list is not complete; a scheme refused and lodged again appears twice. No applicant is named.

How these figures are made. Dún Laoghaire-Rathdown County Council publishes invalid applications as a decision, so 12.2% of applications received in 2023 to 2025 show as invalid. The other 27 authorities do not record invalidations in the national register at all, so this figure is not comparable between authorities and is not used in any rate on this page. Register data to 21 September 2026; a recent application may take some weeks to appear. Completions are the CSO's quarterly series by local authority; commencements are the CSO's monthly series of commencement notices. The comparison table sets every authority side by side.
