Retention planning permission in Ireland — refused 27% of the time, against 7% for extensionsOne in six Dublin applications is for retention, and 27% of retention decisions in the two years to September 2026 were refusals. When you need it, the treble fee, the seven-year rule and the sale-time problem.
Planning permission for an extension in Ireland — the 45 m² exemption and a 94% grant rateDublin councils granted 94% of extension applications decided in the year to September 2026. Since 27 July 2026 a rear extension of up to 45 m² can be exempt. The conditions, when you still apply, the fee and the timeline.
Planning application fees and costs in Ireland — €34 for an extension, €65 for a house, treble for retentionThe council fee is the smallest cost of a planning application. Schedule 9 fees for a house, an extension, retention and commercial floor space; the €20 observation, the €220 appeal, development contributions and what the drawings and notices cost.
Site notice planning rules — 22% of Dublin applications invalid, and the notice is the top cause2,539 of the 11,409 applications received by Dublin councils in the year to September 2026 were declared invalid; in South Dublin nearly half were for the site notice.
