What buyer protections apply to off the plan apartments?.

Reviewed 12 Oct 2026
Short answer. For an off the plan lot in a residential apartment building of the relevant class and above a set height, the Sale of Land Act 1962 adds protections. Under section 9ADA the vendor must not let the buyer take possession before an occupancy permit is issued, and under section 9AEA the buyer may rescind and recover all money paid, with penalty interest, if the developer has not arranged the required developer bond.

Certain apartment buildings attract extra protection, being residential apartment buildings classified under the Building Code of Australia as the relevant class and above a set height.

Under section 9ADA the vendor must not require or permit the buyer to take possession of the lot before an occupancy permit has been issued for the lot or the part of the building containing it. Under section 9AEA the buyer may rescind the contract and recover all money paid, including the deposit and penalty interest determined under the Penalty Interest Rates Act 1983, if the developer has not arranged a developer bond, or has arranged one securing less than the amount required under the Building Act 1993.

These sit alongside the general off the plan protections, the sunset rules under sections 10A to 10F, and the owners corporation insurance obligation under section 9AAA.

What to watch

The developer bond regime funds rectification of defects, so its absence is a serious matter that can justify ending the contract. Possession before an occupancy permit is not permitted for these buildings.
