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.
See section 45(1)(e) of the Building Act:
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.

It is possible in some circumstances to get an owner builder exemption for DIY work that is restricted building work. Applications need to include a statutory declaration from the owner which is avaliable from the www.building.govt.nz/projects-and-consents/planning-a-successful-build/scope-and-design/choosin-the-right-people-for-your-type-of-building-work/owner-builder-obligations/.
