Dún Laoghaire-Rathdown: homes with planning permission that nobody has started

By local electoral area 7

By year granted

Recent years are still open: a permission granted this year has had months, not years, to start.

Who holds the permissions 29 named

The organisation named on the grant, ranked by homes permitted and not started. Names are on 36% of the homes in this council; a company that only appears in a council without a name source is not here. Private individuals are never named.

How it is counted

• A site is one grant of permission for 10 or more homes since 2017: the register's own unit count where the council publishes one, else the count written in the description ("48 no. apartments"). Retention, outline and extension-of-duration applications are not grants of new homes and are left out. Strategic housing developments the Board decided directly (2017–2022) come from its case list.
• Started means a commencement notice on the Building Control Management System names the permission. A notice is lodged 14 to 28 days before work begins, so this is a count of sites where building was formally begun, not of homes finished.
• Not started is a live permission with no notice. Lapsing is one that expires within 12 months; lapsed is past its expiry. The expiry is the register's where it has one, else five years from the grant (s.40 of the Planning and Development Act 2000). An extension of duration granted later is not seen here.
• When a later grant amends an earlier one on the same site (a large-scale residential development revising a strategic housing permission, a scheme quoting its parent reference) only the later one is counted, so one site is one count of homes.
• The Department's 4Dublin pipeline counts every permitted unit from 2016 and reports 41.9% "activated" at Q2 2026; this table counts sites of 10+ from 2017 and starts on the permission itself, so the two will not match to the unit. The point is the map, not the total: which sites, where, and when they lapse.
