Building Regulations


In Northern Ireland each District Council is responsible for the enforcement of building regulations.

Responsibilities include the passing of plans within council boundaries or the enforcement of building standards and regulations on improvement work. The functions are carried out by each council’s Building Control Department.

Examples of works subject to building control include:

  • Erecting a new building
  • Extending an existing building
  • Changing the use of a building (e.g. house to offices)
  • Converting a roof space or garage
  • Replacing existing walls, floors, roofs, and stairs
  • Making two rooms into one
  • Removal of a chimney breast
  • Installing cavity wall insulation
  • Dry lining walls or lining walls/ceilings with sheeting or boarding
  • Replacing fire doors
  • Provision of services or fittings – for example:
    • Installation of central heating
    • Replacement/relining flues.
    • Installation of new sanitary appliances (not replacement only)

Planning permission may also be required in advance. You can find more information on NI Direct.
