How it is counted

A neighbourhood is a CSO electoral division; its households and population are the 2022 census totals of the small areas inside it. Every application, appeal and building-start notice is counted in the division where it is on the map.
Household works are applications whose description says extension, attic, dormer, porch, garden room, garage conversion and the like, and does not say apartments, units, commercial, retail or office.
Work already done (retention) is an application to keep something that was built without permission: its type or description says retention. Its grant rate is shown where at least ten were decided.
Decisions count grants and refusals only; invalid, withdrawn and undecided applications are left out of every rate. Days are from the council’s receipt date to its decision date.
A rate is printed only where the neighbourhood has at least 20 of the thing being rated in the window; smaller ones show counts and are not ranked.
Councils have no per-household figures outside Dublin: the census spine is loaded for the Dublin region only.
