Building notice application

Building notices are aimed at domestic properties for minor building works like:

  • Conversion of an attached garage to a habitable room
  • Formation of a through lounge

You can also submit a building notice when building an extension or a new dwelling is being built. 

A full plan application must be submitted when the proposed building works involves:

  • building over or within three metres of a public sewer

Regularisation application

Alterations or extensions done without a submitted building regulation application is deemed 'unauthorised'. Problems are likely to occur when selling the property.
