About this data
Figures are the Department of Housing, Local Government and Heritage's Residential Zoned Land Tax Final Map for 2026, read directly from its published map service. Hectares are the site area recorded on the map, not a parcel count. Town totals assign each mapped site to the nearest town we track within 5 km in Co. Dublin; sites further than that are counted in the county total above but not attributed to a town. The next map in this series is the 2027 draft map, due by 31 January 2027. See the Leinster RZLT overview and methodology for house rules.
