Cooling-off rights for NSW residential building contracts

The 5 clear business day cooling-off period under section 7BA of the Home Building Act 1989, when it applies (over $20,000 incl GST), how rescission works, refund obligations, and the extended rescission right under section 7BB when the prescribed cooling-off warning is missing from the contract.

What the cooling-off period is

The cooling-off period is a statutory right for a homeowner to rescind a residential building contract within a short window after signing, without having to give a reason. It exists to protect homeowners from pressure-sale tactics and from signing a contract they have not had time to consider. The right is set out in section 7BA of the Home Building Act 1989 (NSW) and applies on top of any cooling-off provision in the contract itself.

When the cooling-off period applies

Cooling-off applies to a residential building contract between a homeowner and the holder of a contractor licence where the contract price exceeds $20,000 incl GST. That threshold is the prescribed amount under the Home Building Regulation 2014. Where the contract price is not known at signing, the test is the reasonable market cost of the labour and materials.

Below $20,000 no statutory cooling-off applies, although some contracts include a contractual cooling-off period of their own. Owner-builders are not contractor licence holders so cooling-off does not apply to owner-builder work. Contracts between commercial parties (for example, a builder contracting with a developer) sit outside the residential scheme.

How the period runs

The cooling-off period is 5 clear business days. The window opens when the homeowner is given a copy of the signed contract, not when the contract is signed. Practically this matters because a contractor who signs the contract and walks away with the only copy leaves the cooling-off window paused until a copy is delivered to the homeowner.

"Clear business days" excludes the day the copy is received, weekends and NSW public holidays. A copy delivered on a Friday gives the homeowner until end of business the following Friday to rescind.

How rescission works

To rescind, the homeowner gives written notice to the contractor before the cooling-off period expires. The notice does not need to use any particular form, but it must clearly state that the homeowner is rescinding the contract under section 7BA. Email and post are both acceptable. Verbal rescission is not.

The contract is taken to be rescinded from the time it was signed. The contractor must refund all money paid under the contract. The Act allows the contractor to retain a deduction for any reasonable out-of-pocket expenses incurred before the rescission, such as the cost of a site visit, soil report or design work already commissioned. The deduction must be genuinely reasonable and must be evidenced.

Extended rescission if the cooling-off warning was not given

The Home Building Act requires the contract to include a prescribed cooling-off warning telling the homeowner about their rescission right. If the contractor failed to include the warning, section 7BB allows the homeowner to rescind the contract at any time before completion of the work. The window is not capped at 5 business days; it can extend for months across substantial work already done. This is a significant exposure for any contractor who uses an out-of-date template or omits the prescribed warning.

The remedy in this extended case mirrors section 7BA. The contractor must refund all money paid less reasonable out-of-pocket expenses. The difficulty is that the "reasonable" deduction tends to be much smaller than the actual cost of work performed across an extended rescission window, so the contractor wears a larger loss.

Practical implications for builders

Three habits keep a contractor on the right side of the cooling-off rules.

Use the current edition of the contract. HIA and Master Builders forms include the prescribed cooling-off warning in their standard residential contracts. Older copies of the contract or marked-up bespoke contracts may have an out-of-date warning or none at all. A lawyer review of any custom contract should specifically confirm the cooling-off warning is current and prominently placed.

Give a copy of the signed contract to the homeowner the same day it is signed and record the date and method of delivery. A signed acknowledgment of receipt removes any later argument about when the cooling-off window started.

Do not start work, take a deposit beyond the statutory 10% cap under section 8, or order materials before the cooling-off window has closed. Work performed inside the window is reimbursable only as a reasonable out-of-pocket expense if the homeowner rescinds, which is rarely a clean reconciliation.

Related entries

Contract requirements that sit alongside cooling-off (including the prescribed warning content) are covered in the choosing-residential-building-contract entry. The deposit cap that limits what money is in play during the cooling-off window is in the progress-payment-rules entry. Statutory warranties under section 18B run separately from cooling-off and apply regardless of whether the contract is rescinded or completed.
