In order to improve public awareness of the requirements of the building regulations, circular letter PD 3/2003, issued by my Department on 14 April 2003, I requested that all planning authorities should issue a copy of departmental leaflet, PL11 — Guide to the Building Control System, to every recipient of planning permission for housing developments. A similar request was also made to An Bord Pleanála, in connection with the notification of the grant of planning permission, on appeal, for housing developments. I am satisfied that leaflet PL11 provides adequate guidance to house builders of their obligations under the building regulations.
