Please Note: The applicant must be the owner of the site or have permission in writing from the owner of the site to pursue pre-planning advice (if applicable, this should also be lodged).

The Planning Authority will keep a record of any such consultations which will be a matter of public record on foot of a planning application being subsequently lodged.

The carrying out of such consultations shall not prejudice the performance by a Planning Authority of any other of its functions under the Planning and Development Act 2000, (as amended), and cannot be relied upon in the formal planning process or in legal proceedings.
