Calculations are based on the minimum or maximum timeframes outlined in the Planning and Development Act 2024. The use of maximum timeframes may result in a calculation of a review period which exceeds the statutory timeframe for the completion of the review and preparation of a development plan under the Act. In addition, local authorities may take additional steps other than those captured in the calculators which may result in an extension of the plan review process and associated timeframes.
Timeline: When you create a timeline it will calculate the dates going forwards and backwards for all stages in the relevant plan-making process.
Additional days: As per Section 402(1) – when calculating any period or time limit of one year or less specified by or under this Act the period between the 24th day of December and the 1st day of January, both days inclusive, shall be disregarded. Therefore, the calculators add 9 days to steps which occur during these dates.
