How to submit an observation

  1. Read the file on the council register.Drawings, planning statement and site notices are at https://planning.agileapplications.ie/dunlaoghaire/application-details/107364.
  2. Write your observation.Quote D26B/0572/WEB at the top, give your name and the address the authority should reply to, and confine it to planning matters — zoning objective, height, overlooking, traffic, drainage, heritage. What you say here is what you can later appeal on.
  3. Pay the €20 fee.Every submission needs it; without it the observation is invalid and is returned. Dún Laoghaire-Rathdown County Council takes it online with the submission or at the counter.
  4. Submit before 10 Dec 2026.Online through the register above, or in writing to the Planning Department, Dún Laoghaire-Rathdown County Council. The test is the date the authority receives it, not the date you post it.
  5. Keep the acknowledgement.The council's receipt is your proof of a valid observation — see below.

Statutory basis. Section 34(1) of the Planning and Development Act 2000 (as amended) requires a planning authority to consider any submission or observation made to it in accordance with the Regulations. Article 29 of the Planning and Development Regulations 2001 (as amended) sets the window: a submission or observation must be received by the authority within five weeks beginning on the date of receipt of the application, and must be accompanied by the prescribed fee of €20. A submission received after the window, or without the fee, is invalid and the authority must return it.

After you submit: keep the acknowledgement. Under the 2024 Act it secures your right to appeal — only the applicant and a person who made a valid observation may bring the council's decision to An Coimisiún Pleanála, within four weeks of the decision. Making a valid observation is also what buys a right of appeal: under s.37(1) of the 2000 Act, only the applicant and a person who made a valid submission or observation to the planning authority may appeal the decision to An Coimisiún Pleanála (within four weeks of the decision). Missing the five-week window closes both doors.

An application that accords with the zoning objective is hard to resist on principle; one that does not may be a material contravention, which the council can only grant by the s.34(6) procedure with its own notice and window.

If neighbours here have appealed before and lost, the inspector's report on that case is the single most useful thing to read.
