Exempted Development ‌


Exempted development is development that does not require planning permission, the purpose of which is to facilitate developments of a minor nature. However the development must fall within the exemption thresholds. If the development exceeds the thresholds, the development requires planning permission. 

Categories of exempted development and thresholds are set out in planning law (Planning and Development Act 2000 updated to May 2017) and the Planning and Development Regulations (as amended)).
