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 will be 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:

Section 45(1)(e) - Building Act 2004 - NZ Legislation website

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.

Owner builder exemption

Owner-Builders are able to carry out Restricted Building Work on their own home.  To see if you qualify as an Owner-Builder and to learn more about the Owner-Builder Exemption visit Ministry of Business, Innovation & Employment website 

DIY work

Most DIY work is usually minor repair, maintenance or alteration work and doesn't fall within the category of Restricted Building Work.  For this work nothing has changed and home owners can continue to do this work as they always have.

An Owner-Builder is responsible for ensuring that Restricted Building Work carried out under the Owner-Builder Exemption complies with the building consent and the relevant plans and specifications.  More information can be found on the Ministry of Business, Innovation & Employment website:
