Exempted Development

Exempted development is development for which planning permission is not required. Categories of exempted development are set out in planning law. There are usually certain thresholds relating to, for example, size or height. Where these thresholds are exceeded, the exemptions no longer apply. The purpose of exemptions is to avoid controls on developments of a minor nature, such as small extensions to houses. Leaflets PL.5, PL.6 and PL.7, which are available from your local planning authority, give details of the main exemptions.
