Understanding Off-the-Plan Contracts in South Australia

What Is an Off-the-Plan Contract?

An off-the-plan contract is a legally binding agreement to purchase a property that has not yet been built – or has not been fully constructed – at the time of signing. In South Australia, these contracts are governed by the Land and Business (Sale and Conveyancing) Act 1994 and supplemented by the general law of contract. Because the subject matter does not physically exist at the time of execution, these agreements carry a unique set of risks that differ materially from a standard residential conveyance.

Purchasers are typically required to pay a deposit – commonly 10% of the purchase price – which is held in trust until settlement. Settlement occurs once the development is registered and a Certificate of Title is issued in respect of the specific lot being purchased. That gap between signing and settlement can span anywhere from six months to three or more years, during which market conditions, lending environments, and the purchaser's personal circumstances may change dramatically.

Key Contractual Risks to Understand

One of the most significant risks in an off-the-plan purchase is the sunset clause. A sunset clause entitles either the vendor or the purchaser to rescind the contract if the development is not completed by a specified date. Historically, some developers have deliberately delayed registration to invoke sunset clauses and re-sell lots at higher market prices. South Australian legislation now imposes restrictions on vendor-initiated sunset clause rescissions, requiring genuine grounds and, in some cases, Supreme Court approval, but purchasers should still review these clauses carefully with their solicitor before signing.

Another area of concern is the permitted variations clause. Most off-the-plan contracts grant the developer a right to make variations to the building design, materials, floor plan, and finishes – sometimes to a substantial degree – without triggering a right to rescind on the part of the purchaser. It is critical to understand what variations are permitted and whether minimum specifications are locked in. A professional review of the inclusions schedule and any accompanying plan of division can reveal ambiguities that leave purchasers with far less than they bargained for.

Finance and Valuation Risk

Purchasers who rely on pre-approval finance at the time of signing may find that their borrowing capacity has changed significantly by settlement. Lenders will typically conduct a fresh valuation of the property at or near settlement, and if the completed property is valued below the contract price – a not uncommon outcome in a declining market – the purchaser may be required to fund a shortfall or face default. This is sometimes referred to as a "valuation gap" and it can place purchasers in an extremely difficult position.

It is also worth noting that the First Home Owner Grant and stamp duty concessions may be affected by changes in legislation between signing and settlement. Purchasers should not assume that the concessions available at the time of signing will still be available – or calculated in the same way – by the time settlement occurs. Your solicitor can help you understand the current eligibility criteria and flag any pending legislative changes.

What to Do Before You Sign

Before executing any off-the-plan contract, we strongly recommend engaging a solicitor with specific experience in off-the-plan transactions to review the contract in its entirety – including the vendor's statement, the plan of division, the inclusions schedule, and all special conditions. Key issues to scrutinise include the sunset date and rescission rights, the permitted variations clause, the deposit terms and interest provisions, the body corporate or community corporation structure, and the estimated completion date and any delay provisions. Understanding your rights and obligations before you are bound by the contract is far preferable to seeking remedies after the fact.
