Planning permission for farms

Permitted development

Permitted development means that if your farm is 5 hectares or more, you have the right to:

  • erect, extend or alter a building
  • carry out excavations and engineering operations needed for agricultural purposes - though you may still require approval for certain details of the development.

The types of permitted development include:

  • temporary uses of land
  • agricultural buildings below a certain size
  • forestry buildings
  • caravan sites and related buildings in some circumstances

Check with your local planning authority (or local area planning office in Northern Ireland) before making use of permitted development rights to make sure your development won’t need planning permission.

The Agricultural Document Library (ADLib) has policy planning guidance on permitted development and farms.
