Buying a house with owner-builder work in QLD

TLDR: If a house you are buying had owner-builder work done on it, there is no Queensland Home Warranty Scheme cover on that work. None. If defects show up after settlement, there is no insurer to call. The seller has to tell you in writing if they are selling within six years of finishing, and the owner-builder notation sits on the title for seven years. Get the contract reviewed before you sign. Call 07 3088 7675.

Owner-builder homes are not a problem in themselves. Plenty of them are built properly by people who cared more than a contractor would.

The problem is what you lose as the buyer, and almost nobody explains it before the contract is signed.

What owner-builder work actually means

In Queensland a homeowner needs an owner-builder permit from the QBCC for residential building work on their own land valued at more than $11,000. For farm buildings the threshold is $27,500.

The QBCC will only issue one permit to a person every six years, and most applicants have to complete an owner-builder course before they can apply.

So when you hear “the previous owner did the extension themselves”, that is not a casual DIY story. If it was worth more than $11,000 it required a permit, a course and a QBCC record.

The part that costs buyers money: no warranty cover

This is the single most important thing to understand.

Owner-builders are not eligible for the Queensland Home Warranty Scheme.

When a licensed builder does residential work over the threshold, the Home Warranty Scheme sits behind it. If the work is defective, or the builder does not finish, or the builder disappears, there is a scheme to claim against. It is the safety net the whole system runs on.

Owner-builder work has none of that. If the waterproofing under that owner-built bathroom fails in year three, you are not making a claim. You are paying for it.

That is not a reason to walk away from every owner-builder property. It is a reason to price it properly and to inspect it far more carefully than you otherwise would.

The seller has to tell you – in writing

This sits in section 47 of the Queensland Building and Construction Commission Act 1991. If an owner-builder sells within six years of finishing the work, they must give the buyer two copies of a notice setting out the work, who did it, and that it was done under an owner-builder permit. The buyer signs one copy and returns it on or before the day the contract is signed.

The notice has to carry this warning in these words:

Warning – the building work to which this notice relates is not covered by insurance under the Queensland Building and Construction Commission Act 1991.

What happens if the seller does not give it

This is the part sellers underestimate. If the notice is not given, the seller is treated as having warranted to the buyer that the building work was properly carried out.

Think about what that means. Skip a piece of paperwork, and instead of selling a house with uninsured owner-builder work clearly flagged, you have personally guaranteed the quality of that work to the person buying it. If defects surface later, the buyer has someone to pursue – and it is you.

Two things follow from that.

First, if you are buying and nobody has mentioned owner-builder work, ask the question directly and get the answer in writing. “I did not know” is a much weaker position after settlement than before it.

Second, if you are the one selling, this is not optional and it is not something to leave to the agent to remember. It sits alongside the rest of your seller disclosure obligations, and the consequences of getting disclosure wrong in Queensland have got sharper, not softer.

It shows up on the title for seven years

The owner-builder administrative advice is recorded on the property title and stays there for seven years. The former owner-builder can apply to have it removed once six years have passed since completion.

For you as a buyer, that is genuinely useful. It means a proper title search can surface owner-builder work even when the conversation has not. It is one of the few risks in a Queensland purchase that leaves a documentary trace.

It also means the reverse is true. If the work was done more than seven years ago, or the notation has been removed, the title will not tell you. That is where the building inspection has to do the work.

What to do before you sign

• Ask, in writing, whether any owner-builder work has been done and when it was completed. Date matters – it drives both the six-year notice obligation and the seven-year title notation.
• Order the title search early and actually read the administrative advices, not just the ownership and encumbrances.
• Do not treat a standard building and pest inspection as enough. Tell the inspector there is owner-builder work and ask them to look specifically at waterproofing, structural changes, decks and any wet areas. A building and pest condition is only as good as the brief you give the inspector.
• Ask whether council approvals and final certificates exist for the work. Permit and approval are not the same thing, and unapproved structures become your problem the day you settle.
• Factor the missing warranty into your price, not your optimism.

If the work was never approved

This is the scenario that turns into real money.

Where owner-builder work was done without the necessary approvals, the liability follows the property, not the person who did it. After settlement, you are the owner of an unapproved structure, and under the Building Act 1975 the council can issue a show cause notice and then an enforcement notice to the owner for the time being – which is you. That can mean obtaining retrospective approval, rectifying the work, or in serious cases removing the structure. You pay either way.

If a search or an inspection turns up work that does not match the approvals on file, that is a conversation to have before the contract becomes unconditional, not after. Depending on the contract and the timing, there may be a way out or a way to renegotiate. Once you are unconditional, your options narrow sharply.

Frequently asked questions

Does home warranty insurance cover owner-builder work in QLD?
No. Owner-builders are not eligible for the Queensland Home Warranty Scheme, so there is no insurer standing behind the work if defects appear.

Do I have to be told if a house had owner-builder work?
If the owner-builder is selling within six years of completing the work, section 47 of the QBCC Act requires them to give you a signed notice carrying a warning that the work is not covered by insurance. If they do not, they are treated as having warranted the work was properly carried out. Outside that window, ask directly and check the title.

How long does owner-builder work stay on the title in Queensland?
The administrative advice is recorded for seven years. The former owner-builder can apply to remove it six years after completion.

What value of work needs an owner-builder permit in QLD?
More than $11,000 for residential building work on your own land, or more than $27,500 for farm buildings.

Can I still buy a house with owner-builder work?
Yes, and plenty of people do. You are accepting a property with no warranty scheme behind part of it, so the inspection needs to be sharper and the price needs to reflect it.

Get the contract looked at first

Owner-builder work is one of the things we check for as part of a contract review, because it is cheap to find before you sign and expensive to discover after you settle.
