PPS 9: The Enforcement of Planning Control
Where unauthorised development is unacceptable and urgent remedial action is required
7.1 Where, in the view of the Department, unauthorised development is causing serious harm to public amenity and there is little likelihood of the matter being resolved voluntarily or through negotiations, the Department will normally take vigorous enforcement action. This may include the service of a stop notice with, or on the foot of, an enforcement notice, or, where circumstances permit, an injunction to remedy the breach urgently in order to prevent further serious harm to public amenity. Where any person fails to comply with a stop notice they are guilty of an offence and the Department will normally pursue court action. On summary conviction that person is liable to a fine with the potential for continuing daily fines.
