Laws about domestic building payments

The law governing home building contracts in Victoria is the Domestic Building Contracts Act 1995. Among other things, this law:

  • sets an amount for the deposit
  • defines the stages of building and how much the client pays for each stage
  • only allows certain changes to the contract price (legal changes include variations, and prime cost and provisional sum items).

Other relevant laws include the Australian Consumer Law and Fair Trading Act 2012, which requires contracts to be clear and fair.

Taking deposits for domestic building work

By law, a deposit can be no more than:

  • 10 per cent, if the total contract price is less than $20,000
  • five per cent, if the total contract price is $20,000 or more.

You must give your client a copy of your domestic building insurance policy and a certificate of currency covering their property before you take a deposit or any other money for work worth more than $16,000.

Stage payments/progress payments for domestic building

The contract must set out the price and stage payments (you must have a major domestic building contract for most work worth more than $10,000, even if your client is an owner builder).

By law, your client pays for completed stages. These are:


Complete when:


Depends on type of floor:

Security of payment and domestic building

The Building and Construction Industry Security of Payment Act 2002 does not apply to domestic building work. It enables subcontractors working in commercial developments who have not been paid by their contractor to recover unpaid amounts against the commercial developer/owner.

So, by law, claims cannot be made against home owners commissioning domestic building work unless the home owner is a commercial builder.
