Defects Liability Period Australia: What Investors Should Know Before Handover

Handover day feels like the finish line on a build, but for an investor it's actually the start of an important phase called the defects liability period. This is the window after practical completion where the builder remains responsible for fixing issues that show up as the property is used and settles in.

A lot of investors assume that once the keys are handed over, any problems become theirs to sort out and pay for. That's not how it's meant to work, but making the most of the defects liability period requires knowing what it covers, how long it lasts, and what to do if the builder is slow to respond.

What The Defects Liability Period Covers

The defects liability period is a set timeframe, defined in the building contract, during which the builder is obligated to return and fix defects that appear after the property has been handed over. This is separate from statutory home warranty insurance, which typically runs for a much longer period covering structural and major defects.

Defects during this period generally fall into minor and major categories. Minor defects might be things like a sticking door or a small paint touch-up, while major defects could involve issues like water penetration or problems with a structural element.

How Long It Typically Lasts

In most Australian states, the defects liability period for residential construction runs for around three to six months from practical completion, though the exact period is set out in the specific building contract and can vary by builder and by state regulation.

It's worth reading this clause carefully in your contract before signing, rather than assuming a standard length applies. Some contracts specify different periods for different types of defects.

Steps To Take At Handover

The condition of the property at handover sets the baseline for everything that follows, so a thorough inspection before or at practical completion matters more than most first-time investors realise.

• Arrange an independent building inspection before signing off on practical completion
• Create a detailed, photographed list of any visible defects at handover
• Confirm in writing which items the builder has agreed to fix and by when
• Keep a copy of the building contract's defects clause on hand for reference
• Note the exact start and end date of the defects liability period

Managing Defects As They Emerge

Some defects only become visible after the property has been lived in through a season or two, such as cracking as the building settles or issues that only show up during heavy rain. It's worth doing a follow-up inspection partway through the defects period rather than waiting until the very end to report everything at once.

Report defects to the builder promptly and in writing, keeping a clear record of dates and descriptions. This creates a paper trail that matters if a dispute arises later about whether an issue was raised within the defects period.

• Do a follow-up walkthrough partway through the defects period, not just at the very end
• Report issues in writing, with photos, as soon as they're noticed
• Keep copies of all correspondence with the builder about defect repairs
• Distinguish clearly between normal wear and genuine construction defects
• Follow up on agreed repair timeframes rather than assuming they'll happen automatically

When A Builder Won't Respond

If a builder is slow, unresponsive, or disputes that something is a genuine defect, most states have a building commission or fair trading body that can help mediate or formally investigate the issue. It's worth knowing which body applies in your state before you need it.

This is also where statutory home warranty insurance can come into play, particularly if a builder has gone out of business or is refusing to honour their obligations altogether.

Final Word

The defects liability period exists to protect you after handover, but it only works if you document the property's condition properly and follow up during the window, not after it's closed. Treat the handover inspection as seriously as any other stage of the build.

If you're new to this process, an independent building inspector is worth the modest cost, both at handover and again partway through the defects period, to make sure nothing gets missed while the builder is still on the hook to fix it.
