Residential Building Contracts

Residential Building Contracts

Specialist advisory for residential building contracts across Australia - ABIC contracts, Home Building Act compliance, and contract structuring for projects in every state and territory

Residential building contracts in Australia are heavily regulated. Every state and territory imposes mandatory requirements on the form and content of contracts for domestic building work, requirements that differ materially from one jurisdiction to the next.

In New South Wales, the Home Building Act 1989 mandates specific contract inclusions, imposes limits on deposits, requires home building compensation fund certificates, and provides statutory warranties. In Victoria, the Domestic Building Contracts Act 1995 imposes different mandatory provisions and progress payment limits. Western Australia’s Home Building Contracts Act 1991, Queensland’s QBCC Act, and the legislation in South Australia, Tasmania, the ACT, and the Northern Territory each have their own requirements.

Christopher Larcos provides specialist advisory on residential building contracts, with a particular focus on ABIC contracts used for architect- administered residential building work. His dual qualification as a solicitor and architect means he understands both the legal compliance requirements and the practical construction context, whether the project is in Sydney, Melbourne, Brisbane, Perth, Adelaide, Hobart, Canberra, or Darwin. If you are still deciding on a form, his guide on choosing the right building contract compares the HIA, ABIC and Master Builders options.

Depending on the governing legislation and the nature of the issue, a non-compliant residential building contract may affect enforceability or payment rights, or expose a party to statutory consequences. Advice at the contract stage can identify those risks early and reduce the likelihood of those consequences, at a fraction of the cost of dealing with them mid-construction.

Common questions

What must a residential building contract include?

The required content depends on the jurisdiction, but commonly addresses the parties and licensed builder, scope and plans, price or pricing method, deposits and payments, variations, warranties, insurance and dispute procedures.

Which residential building contract should I use?

The choice between an ABIC, HIA, Master Builders or bespoke form depends on the project's value and complexity, the intended administration model and the governing state or territory legislation.

Do residential contract rules differ by state?

Residential building work is regulated differently across Australian jurisdictions, with different contract, payment, warranty and procedural requirements.

Can an ABIC cost-plus contract be used for residential work?

ABIC CP-2014 C was drafted as a commercial form and must be checked against the residential building regime applying to the project. It may require tailored compliance conditions before residential use.
