Cooling-off rights for WA home building contracts

What the WA position is

Western Australia does not have a statutory cooling-off period for home building work contracts. The Home Building Contracts Act 1991 (WA), which governs home building contracts in WA, does not contain a statutory rescission window equivalent to those in NSW, Victoria or Queensland. This is the current position as of 2026, although the HBCA is under a Building and Energy review that has cooling-off on the table.

Why this matters

A WA homeowner who signs a home building work contract is bound from the moment of signing. Unlike NSW, Victoria and Queensland, there is no automatic window to walk away without cause. The legal exits are:

• Rescission for misrepresentation, fraud or duress at common law.
• Termination for breach if the builder breaches a term of the contract.
• Termination under a clause in the contract itself (most major-builder contracts include limited termination rights).
• Avoidance under the Australian Consumer Law where the contract was made through an unsolicited consumer agreement (door-to-door sale or unsolicited contact). The ACL 10-business-day cooling-off applies to those rare cases, not to a builder selected by the homeowner.

Comparison with other states

NSW: 5 clear business days for residential building contracts over $20,000 incl GST under Home Building Act 1989 s 7BA.

VIC: 5 clear business days for major domestic building contracts over $10,000 incl GST under Domestic Building Contracts Act 1995 s 34.

QLD: 5 business days for regulated residential building contracts over $3,300 incl GST under QBCC Act Schedule 1B.

WA: no statutory cooling-off period.

If a WA homeowner needs the same protection, that has to come from a clause inside the contract itself or from an ACL unsolicited-agreement scenario. It does not come from the HBCA.

Practical implications

For WA residential builders:

Do not rely on cooling-off rules from another state when drafting WA contracts. They do not apply.

If a homeowner asks about cooling-off, be honest that WA does not provide one statutorily, then explain what termination rights the contract itself gives.

Watch for an HBCA amendment. The Building and Energy 12-month review running through 2026 has flagged cooling-off as a topic under review. The position in this entry may change once the review reports.

For WA homeowners:

Read the contract carefully before signing. There is no walk-away window once it is signed.

Get independent advice before signing, especially on price, progress payments and termination clauses.

If the contract was offered through an unsolicited approach, the ACL may provide a separate cooling-off right.
