Lawful development for an existing use application checklist
A Certificate of Lawful Existing Use or Development (CLEUD) can be sought where a development has already been implemented without planning permission to ascertain whether it is lawful. A development may be lawful and therefore granted a certificate where: planning permission was not required for whatever reason for the development, the development is now immune from enforcement action because it has been in place for more than 4 years, or alternatively an involved use has been carried out for more than 10 years.
A valid CLEUD provides a defence against enforcement action and makes the development to which it relates lawful.
This is a checklist of things that should be included in an application.
