Retention is the second chance Irish planning offers for what’s already built — and it works, constantly, for ordinary development. What the myths skip: it’s decided on the same test as any application, the application itself concedes the breach, and there’s an alternative worth checking first.
The Same Test — and What That Means for Yours
Retention is permission sought for existing works or uses, decided on the proper planning and sustainable development of the area — exactly as if you’d applied before building. The equivalence cuts both ways: no penalty for the works existing (if it would have been granted, retention is realistic — the compliant extension, the acceptable garden structure, the modest commercial change), and no indulgence either (if a fresh application would have failed on the plan, on amenity, on access, retention fails the same way — after buying publicity: the site notice describing the retention sought, the public file, the five-week window for any neighbour’s submission, and appeal rights all round). Which is why the assessment happens before lodging, in a planner’s terms: would this have been granted? When the realistic answer is refusal, you’re told before the application creates a public record of the authority’s view — a record every future purchaser’s solicitor will find.
The Sequencing: Section 5 First, and the Closed Door
Two strategic facts frame every retention decision. First, the alternative: where a genuine exemption argument exists — the works arguably within an exempted class all along — the Section 5 declaration resolves the matter without conceding any breach; and lodging retention first surrenders that argument forever, because applying for retention declares the works unauthorised. Section 5 first, retention second, is often the whole strategy. Second, the closed door: development that required environmental assessment or Habitats screening cannot be cured by ordinary retention — European law forbids the after-the-fact shortcut, Irish law was reshaped to close the route, and only the narrow, exceptional substitute-consent gateway remains for that class. Domestic extensions never meet this wall; quarries, agricultural intensification and works near European sites can find it’s everything. And where enforcement is already running: retention doesn’t suspend a notice — compliance clocks keep running — but a credible application changes the practical conversation, with held escalation and negotiated compliance the everyday outcomes when the sequencing is choreographed rather than improvised.
The order of operations, every time: which world (ordinary or assessment-class)? Then Section 5 (does an exemption argument exist worth preserving)? Then the merits (would it have been granted)? Then — and only then — the application. Files that run this order resolve; files that start with a hopeful form create records.
