Building control applications

You can apply online for full plans, building notice or regularisation.

Published on: 9 December 2020

Last updated: 4 February 2021

This application must be made when there is a proposal to carry out building works to:

  • a building which is not a single-family dwelling house
  • erect a building fronting a private street
  • construct over or within 3 metres of a public sewer

The change to extend the types of property needing a Full Plans application is the result of the Regulatory Reform (Fire Safety) Order 2005 (RRO). This requires plans of building work for most buildings to be sent to the Fire Authority for formal consultation.


The advantages include:

  • greater certainty of the final building costs
  • having your plans checked by our surveyors and approved as complying with the building regulations
  • receiving a set of approved plans and near immunity from enforcement action if you build in accordance with those plans


Your application must include a clear description of the work you are proposing to carry out, a full set of plans and any other supporting documents.
