As Minister for the Environment, Heritage and Local Government I have overall responsibility for the legislative and policy framework governing the planning system. The enforcement of planning control is a matter for individual planning authorities, who have substantial enforcement powers under the Planning and Development Acts 2000 – 2006.
With regard to action against unauthorised developments, planning authorities have substantial powers and obligations, under the Planning and Development Acts, in relation to unauthorised developments. The 2000 Act provided for a strengthened enforcement regime and increased penalties on conviction for the offence of unauthorised development. Section 35 of the 2000 Act, as amended in 2006, gives planning authorities a new power to refuse planning permission, without recourse to the High Court, to a developer who has substantially failed to comply with a previous planning permission.
Ultimately, each planning authority has primary responsibility for dealing with applications for permission and planning enforcement within its own area. I do not propose, therefore, to establish a national database along the lines outlined in the Question.
