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.
An Bord Pleanála appeal, now An Coimisiún Pleanála — four weeks, €220, and a 25% reversal rateThe Commission reversed the council in 25% of the 1,195 Dublin-area appeals decided in the two years to September 2026. Who can appeal, the four weeks, the €220 fee, why 240 appeals a year fail on procedure, and the odds by direction.
Certificate of compliance with planning permission in Ireland17% of GDA planning applications are retention. Who can sign a certificate of compliance with planning permission, what the RIAI / Law Society opinion covers, the gaps it leaves.
