A Section 5 Declaration is the cheapest way to resolve whether your project needs planning permission. Ruling is binding.

A Section 5 Declaration is a formal ruling from the local authority on whether your proposed development needs planning permission (i.e. whether it is or is not exempt development). Costs €80. Decision in 4–8 weeks. The ruling is binding on the local authority. Get a Section 5 before you start any work that might be exempt — saves enforcement action, retrospective planning fees, and the cost of undoing unauthorised work. Useful for: change of use, boundary treatments, agricultural structures, extensions in marginal cases, and any work where the line between exempt and not-exempt is unclear.
