What it says

Objective A: A To provide residential development and improve residential amenity while protecting the existing residential amenities

An established residential area. The objective is to protect existing residential amenity as well as to provide housing — which is the objective a neighbour's objection to an overbearing extension is usually argued under.

How we work this out

'On this site' means the record's own map outline touches the registered parcel (or a 12 m circle round the point where there is no parcel). Only the council's own list confirms a protected building; ask the council if in doubt. The council's map for the vacant land tax shows this spot inside an area of existing homes. Homes people live in, and their gardens, don't pay the tax. The OPW flood map's licence lets us show a yes/no only.

How we work this out

Applications whose site outline (or map point) falls on this property. 'No sign building has started' means we found no notice to the council's building control office; small jobs don't always file one, so ask. A missing completion certificate is not proof of a problem: an owner can opt out of official sign-off for a house or extension built for themselves.

How we work this out

Home extensions are read from the application's description (extension, attic or dormer, porch, garage conversion, garden room), so a few may be missed or mislabelled. The kind is the first that fits: a dormer with a rear extension counts as a dormer. Refusal reasons come from An Coimisiún Pleanála's inspector reports, so they exist only where the refusal was appealed (Dún Laoghaire-Rathdown so far). The council's own reasons are on its planning file.

How long, and what if someone objects?

Figure 4

A home extension's journey here

A decision takes 52 days. 1 in 8 is asked for more information, which adds about 57 days. Building starts about 4 months after permission.

What happens to applications within 500 m

Permission isn't building. Of 89 permissions since 2016, 60 show a start notice and 3 have a completion certificate. Most owners opt out of sign-off.

Purple bands are refusals turned into permissions on appeal. "No start notice found" includes small jobs that never needed one and notices we couldn't match.

How we work this out

Each row is a notice the builder sent to the council's building control office before work started. One notice can cover many homes. 'Signed off as finished' means a completion certificate is on file; work done under an opt-out or a short notice doesn't need one.

How we work this out

Homes approved counts schemes of 10 or more homes (one-off houses are not included). Homes started counts every home in a notice that building work was starting. The council figure is the middle value across the council's built-up squares of the same area (3.1 km², about a 1 km circle), so half of them saw more and half fewer.
