A direction can cover part of a council, and the national dataset is incomplete. This asks the planning data service for the exact point and falls back to the council's own statement.
What an Article 4 direction means
HMO Article 4 directions remove the permitted-development right to convert a family home (C3) to a small HMO (C4, 3 to 6 people). Inside one, that conversion needs full planning permission. Councils may also run additional licensing (smaller HMOs) or selective licensing (all private rentals) in designated areas. Planning permission and licensing are separate: a licence does not grant planning permission, and permission does not remove the need for a licence.
