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.
What the site is zoned
| Code | Objective | Plan | In force |
|---|---|---|---|
| R3 Rural cluster | SDZ: To provide for strategic development in accordance with approved planning schemes | SD-001:DP:south-dublin-county-development-plan-2022-2028 | 8 Mar 2022 → 8 Mar 2028 |
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.
