QBCC Complaints: How to Make a Builder Fix Defective Work in Queensland

If your Queensland builder has left you with cracked tiles, a leaking shower, unfinished work, or a defect they keep promising to fix but never do, there's a clear, free process for forcing the issue — and it's more powerful than most homeowners realise. The Queensland Building and Construction Commission (QBCC) can actually order a licensed contractor to come back and fix defective work, with real consequences if they don't.

Here's how the process works in 2026, the deadlines that quietly sink people's claims, and what you need to have ready. We're not lawyers and this isn't legal advice — it's a clear map for homeowners.

The order of operations matters

Like NSW and Victoria, Queensland funnels disputes through a regulator first and a tribunal last. The Queensland Civil and Administrative Tribunal (QCAT) won't accept a building dispute application unless you've already been through the QBCC. So the QBCC is your starting point, not the courthouse.

But there's a step before even that.

The path through a Queensland building dispute

Step 1 — Give your contractor written notice (and a real deadline)

Before the QBCC will step in, you need to have given your contractor a genuine, written chance to fix the problem. Notify them in writing — email or letter — listing every defective or unfinished item, and give a reasonable timeframe (commonly around 14 days) to rectify. You also have to allow them reasonable access to do the work.

That last point has teeth: if you refuse the contractor reasonable access, the QBCC generally can't direct them to rectify, and it can even affect your entitlement under the Queensland Home Warranty Scheme. (The written-notice step isn't required in narrow cases — for example, if the contractor is insolvent, deregistered, or deceased.)

Two things make this step work in your favour, and both are about the record:

• In writing. A builder's verbal "I'll get to it" is unprovable. An email listing the defects with a date and a deadline is evidence.
• Dated and kept together. You'll need to show what the defect is, when you raised it, and that the contractor had a fair chance to respond. That story is only as good as the record behind it.

Step 2 — Lodge a defective work complaint with the QBCC

If the contractor won't fix the work, lodge a defective work complaint with the QBCC. The service is free and the QBCC is explicitly impartial — it decides on the evidence, not on who's most upset.

Mind the deadline here, because it's the one that catches people: you generally need to lodge a defective work complaint within 12 months of becoming aware of the issue. Don't sit on it hoping the builder comes good.

A useful distinction the QBCC draws: a defective work complaint is about the quality of workmanship. A contractual dispute — disagreements about what your contract includes, or how much money is owed — is handled differently, through the QBCC's free early dispute-resolution service while the contract is still active. If you're not sure which bucket you're in, the QBCC's site has examples; it's worth getting it right so your complaint isn't bounced.

Step 3 — The inspection and the Direction to Rectify

Once your complaint is accepted, a QBCC building inspector typically contacts both parties, often trying to facilitate a resolution on that first call, and may attend the site for an inspection.

If the inspector finds the work is defective and the contractor is responsible, the QBCC can issue a Direction to Rectify (DTR) — a legal order to fix the work. In most cases the contractor gets 35 days to comply. Notably, a DTR also appears publicly on the contractor's record in the QBCC online licence search, which is a strong incentive to comply.

Failing to comply with a DTR is serious for the contractor: it can lead to fines, demerit points, and even suspension or cancellation of their licence. A great many disputes are resolved at this stage.

Step 4 — If it's still not resolved: the letter to QCAT

If the QBCC can't resolve the matter under its powers, it issues both parties a letter confirming you've been through the process — which is the key that unlocks QCAT. You then apply to QCAT to have the building dispute heard and determined. QCAT is the formal tribunal stage: more structured, with the option of legal representation, and where binding orders are made.

A safety net worth knowing about: the Queensland Home Warranty Scheme

If your complaint involves residential construction work and can't be satisfactorily resolved through the QBCC's dispute-resolution process, your situation is automatically assessed for eligibility under the Queensland Home Warranty Scheme — you don't lodge a separate form. If a claim is approved, the QBCC may pay for rectification and then pursue the cost from the contractor. Strict timeframes apply, which is one more reason not to delay.

How long do you have? (The deadlines that matter)

Two clocks are running, and missing either can cost you:

• Lodging your complaint: generally within 12 months of becoming aware of the defective work.
• How far back the QBCC can direct a fix: broadly, up to 12 months from practical completion for non-structural defects, and up to 6 years and 6 months for structural defects (QCAT can extend this in some circumstances).

If a deadline is anywhere near, act now and get advice.

A Queensland-specific tip: get variations in writing first

Queensland law is unusually clear here, and it's worth using to your advantage. Variations to a building contract must be agreed in writing before the variation work starts, and a price increase for a variation generally can't be required to be paid until that work is finished. So if your builder is verbally proposing a change "we'll sort out the cost later," that's exactly backwards — politely insist on the written variation, with the price, before they proceed.

The thread running through all of it: your record is your leverage

Notice the pattern across every step: the written notice in Step 1, the evidence in your QBCC complaint, the documentation the inspector weighs, the case you build at QCAT. The QBCC and QCAT don't side with whoever is most certain — they decide on the evidence in front of them. The homeowner with a clean, dated, chronological record is in a different league from the one reconstructing events from memory and old texts.

Almost nobody keeps that record as they go. Decisions get made on site and confirmed by SMS. Variations are agreed verbally. Promises live in a group chat. By the time a dispute is real, the evidence is scattered, undated, and half-forgotten.

That's the gap Chronicle Build closes — it brings every email, text, and decision about your build into one clear, time-stamped timeline as it happens, so if a dispute comes, you can export a ready-organised bundle instead of starting from scratch at the worst possible moment. You hope you never need it; you're glad it's there if you do.

Frequently asked questions

Can I go straight to QCAT for a building dispute in Queensland?

No. You must lodge a complaint with the QBCC first; QCAT won't accept a building dispute application until you've been through the QBCC process and received its letter.

How long do I have to complain about defective work?

Generally within 12 months of becoming aware of the issue for lodging a defective work complaint. Separately, the QBCC can direct rectification up to 12 months from practical completion for non-structural defects and up to 6 years and 6 months for structural defects.

What is a Direction to Rectify?

A legal order from the QBCC requiring a licensed contractor to fix defective work, usually within 35 days. It's published on the contractor's QBCC licence record, and non-compliance can lead to fines or licence action.

Does it cost anything?

Lodging a complaint with the QBCC is free. QCAT charges an application fee if the matter proceeds to the tribunal.

My builder went broke. Am I covered?

You may be eligible under the Queensland Home Warranty Scheme for residential work that can't be resolved through the QBCC process. Eligibility is assessed automatically and strict timeframes apply, so lodge promptly.
