How long is a builder's warranty in Queensland?

In Queensland, a builder’s warranty runs through the Queensland Home Warranty Scheme (QHWS), administered by the Queensland Building and Construction Commission (QBCC). It covers structural defects for 6 years and 6 months and non-structural defects for a much shorter window — you must notice a non-structural defect within 6 months of completion and lodge within 7 months. On top of the insurance, the QBCC Act 1991 gives you statutory warranties you can enforce against the builder directly. The timeframes are set by legislation and applied strictly, so knowing them matters.

Two forms of protection

Queensland, like other states, gives you two overlapping protections:

1. Statutory warranties — Schedule 1B of the Queensland Building and Construction Commission Act 1991 implies warranties into domestic building contracts: that the work will comply with the plans, specifications, and law, be carried out with reasonable care and skill, and use suitable new materials. You enforce these against the builder.

2. The Queensland Home Warranty Scheme (QHWS) — statutory insurance that helps with defective or incomplete work when the builder can’t or won’t fix it. Insurable residential work over $3,300 must be covered by the scheme, and only a licensed contractor can pay the premium.

The Home Warranty Scheme timeframes

This is where Queensland is unusually strict, and where homeowners most often lose rights by waiting. The QHWS defect claim timeframes are:

• Structural defects: you must lodge your claim within 3 months of noticing the defect, and within the 6 years and 6 months coverage period. Structural defects are serious issues affecting the building’s safety, integrity, or habitability — foundation movement, a leaking roof, water penetration, or major non-compliance with building standards.
• Non-structural defects: you must notice the defect within 6 months of completion and lodge within 7 months. These are the cosmetic or minor issues — cracked plaster, misaligned doors, minor tiling faults.

The non-structural window is short. If you find a minor defect eight months after completion, the scheme won’t help — which is why an early, thorough inspection is so valuable.

Notify the builder first

Before you lodge a defective-work claim with the QBCC, you generally have to notify the licensed contractor of the defect and give them a reasonable opportunity to return and fix it. The exception is where the contractor can’t rectify — for example, they’ve died, been deregistered, or gone into liquidation. Keep written proof that you notified the builder and gave them the chance; it’s part of the process.

If the builder is still trading — the QBCC complaint path

For a builder who’s still in business but won’t fix defects, the QBCC’s complaint process lets you lodge a formal complaint. The QBCC can inspect the work and, where a complaint is made out, issue a direction to rectify requiring the builder to fix defective work. This runs alongside the statutory warranties and is often the practical first step before any insurance claim.

Structural vs non-structural — why classification matters

The dramatic difference between the two windows — 6 years 6 months versus roughly 7 months — makes the structural/non-structural line important. Structural defects go to the building’s stability, safety, or habitability, and include serious water penetration and foundation or framing problems. Non-structural defects are the finishes: paint, tiling, doors, and trim.

Because the non-structural window closes so quickly, treat the months right after completion as the critical period to find and report every minor issue.

How to protect your warranty rights in Queensland

Given the strict timeframes, documentation and speed are everything:

• Do a thorough handover inspection and record every defect before you accept the keys.
• Move fast on non-structural items — the window is months, not years. Report them in writing with dated photos as soon as you find them.
• Notify the builder in writing and keep proof, before lodging any QHWS claim.
• Keep your paperwork — the contract, the QBCC insurance notice, and the completion date, which starts the clock.
• Diarise the deadlines. Because the timeframes are applied strictly, note the key dates so you don’t lose a right by a week.

What the Home Warranty Scheme covers beyond defects

The QHWS isn’t only for defects. Because it’s statutory insurance tied to the builder, it also helps when the builder can’t deliver at all:

• Non-completion — if a licensed builder dies, disappears, or becomes insolvent and doesn’t finish the work, the scheme can help you complete it, subject to the policy terms and a legislated cap on the amount claimable.
• Defective work — within the structural and non-structural timeframes set out above.
• Subsidence and settlement — where these meet the definition of a structural defect.

Two points are worth remembering. First, the scheme only applies where the work was properly covered — which is why hiring a licensed contractor and confirming the insurance was taken out matters so much. Second, cover is subject to a maximum claim amount set by legislation, so it’s a floor of protection, not a blank cheque. For everyday disputes with a builder who’s still trading, the statutory warranties and the QBCC complaint process — not the insurance — are usually your route.

The statutory warranties and the insurance scheme work alongside each other rather than instead of one another. The warranties are the promises you can enforce against the builder; the scheme is the safety net for when the builder can’t deliver. In practice, most homeowners start by enforcing the warranties — putting the defects in writing and, if needed, lodging a QBCC complaint — and only reach for the insurance when the builder has died, disappeared, or gone under. Keep both in mind, because the right tool depends entirely on whether your builder is still around to be held to account.

How Queensland compares

Queensland’s short non-structural window is stricter than most states, so early action matters more here than almost anywhere. If you’re building or buying elsewhere, see our guides to builder’s warranty in Australia, Victoria, Western Australia, and home warranty insurance across the states.

Key Takeaways

• Queensland’s builder’s warranty runs through the Home Warranty Scheme (QHWS) administered by the QBCC, plus statutory warranties under Schedule 1B of the QBCC Act 1991.
• Structural defects: lodge within 3 months of noticing, inside a 6-year-6-month cover period. Non-structural defects: notice within 6 months of completion and lodge within 7 months.
• The non-structural window is short — treat the months right after completion as the critical period to find and report every minor defect.
• You must usually notify the licensed contractor and give them a chance to fix the defect before lodging a QHWS claim; the exception is where the builder can’t rectify.
• If the builder is still trading, the QBCC complaint process can result in a direction to rectify — often the practical first step.
• The timeframes are set by legislation and applied strictly, so document defects with dates, act fast, and diarise every deadline.
