What is Domestic building work?

Domestic building work is work associated with the construction, renovation, improvement or maintenance of a home.

A 'home' is any residential premises, and includes any part of a commercial building or industrial premises that is used as a residential premise.

  • a motel, residential club, residential hotel or residential part of licensed premises under the Liquor Control Reform Act 1998
  • a nursing home, hospital or accommodation associated with a hospital
  • any residence that the Regulations state is not a home for the purposes of this definition.

For the full definition, see sections 5 and 6 of the Domestic Building Contracts Act 1995.

Things to remember:

  • If a builder intends to carry out, manage or arrange the carrying out of domestic building work for another person, and the cost of that work is more than $10,000, then the parties must enter a major domestic building contract (this increased from $5,000 on 1/7/17).
  • A builder must not enter a major domestic building contract unless they are registered as a building practitioner under the Building Act 1993. If the value of the work is $16,000 or over, the works must be covered by domestic building insurance. And they must not enter into a contract or carry out the work unless they have been authorised to carry out that work by the registered building surveyor who issued the building permit for the work (when a permit is required).
  • A building surveyor must not issue a building permit for domestic building work to be carried out under a major domestic building contract unless they are satisfied (among other conditions) that the work is to be carried out by a builder who is:
    • registered in the appropriate class of Domestic builder, or
    • registered in the class of Domestic builder (manager), or
