What is restricted building work?

Restricted building work is design or construction work that is critical to the integrity of a building.

From 1 March 2012, only licensed building practitioners are allowed to carry out or supervise restricted building work. Therefore, a consent application that involves restricted building work will need to include the names of LBPs carrying out or supervising that work. This is covered by section 45(1)(e) of the Building Act 2004.

The Government defines restricted building work as that which includes the design and construction of a house or small- to medium-sized apartment, and which covers:

  • primary structure (eg, foundations and framing) - to make sure the building can withstand vertical and horizontal loads
  • external envelope (eg, roofing and cladding) - to make sure the building is weather-tight
  • fire-safety systems (eg, sprinklers, fire alarms) - to make sure people are adequately protected from the dangers of smoke and fire.

Appropriately-licensed LBPs will be responsible for plans and specifications used in a consent application for restricted building work. See section 45(2)–(4) of the Building Act 2004.

Homeowners can find more information about licensed building practitioners, at Choosing the right people for your type of building work.
