What you say here is what you can later appeal on. - Pay the €20 fee.Every submission needs it; without it the observation is invalid and is returned. Fingal County Council takes it online with the submission or at the counter.
- Submit before 1 Oct 2026.Online through the register above, or in writing to the Planning Department, Fingal County Council. The test is the date the authority receives it, not the date you post it.
- 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.

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.
