<aside> ℹ️

Every site in this snapshot is flagged On Register = Yes and Active Case = Yes — the public dataset is the current active register, so those two flags carry no discriminating power within the data. Analysis below focuses on the dimensions that do vary: Admin Area, Date Added, Protected Structure status, and DCC ownership.

Geographic distribution

Sites are heavily concentrated south of the Liffey. The three southern/central areas account for 119 of 134 sites (88.8%), while the two northern areas hold only 15 (11.2%).

Observations

• South Central alone holds a third of all derelict sites and has the highest count of both Protected Structures (5) and DCC-owned sites (9).
• North West is a notable outlier: only 4 sites, none Protected, none DCC-owned.
• All 12 Protected Structures sit in the South Central, Central, and South East admin areas — none in North Central or North West. Note that the "Central" admin area straddles the Liffey, so 4 of the 12 are actually north of the river in Dublin 1 (Parnell St 77 & 78, Frederick St North 30, Dorset St Upper 78).

Additions over time

The register has accelerated sharply since 2023. Over half of all sites currently on the register (76 of 134 = 56.7%) were added in the last ~28 months (2024 → April 2026).

<aside> ⚠️

The register is a current snapshot — sites that have been resolved and removed are not included. The pre-2020 figures therefore understate historical additions (only long-running unresolved cases survive). The post-2023 acceleration is real but is also amplified by survivorship: recent additions haven't had time to be discharged.
