What Is a Section 137B Owner Builder Defect Report?

Under the Domestic Building Contracts Act 1995 (Vic), any property sold within six and a half years of an owner builder permit being issued must include a defect report prepared by a registered building practitioner. This is known as a Section 137B report.

The report must be provided to the buyer before the contract of sale is signed. It’s not optional — failure to provide one can expose the seller to significant legal and financial liability.

Who Needs a Section 137B Report?

You need a Section 137B owner builder defect report if:

  • You performed building work on the property as an owner builder
  • You are planning to sell the property within 6.5 years of the building permit being issued
  • The value of the building work exceeds the threshold specified by the Domestic Building Contracts Act

Frequently Asked Questions

How long does it take to get a 137B report?

We complete the inspection and deliver your report the same day. This means your sale process can keep moving without delay.

Can the buyer use the report to sue me?

The Section 137B report is designed to disclose known defects to the buyer before purchase. Having a thorough, honest report actually protects you as the seller — it limits your liability by ensuring full disclosure.

What if defects are found?

Defects don’t necessarily mean the sale can’t proceed. Many owner builder sales complete with defects documented and priced into the contract. We can talk you through what the findings mean for your sale. If settlement is still ahead, a pre-settlement inspection can also be useful to confirm the property’s final condition before funds transfer.

Do I need a 137B report for renovations as well as new builds?

Yes — the requirement applies to any owner builder work that required a building permit, including major renovations. Check your permit date against the 6.5-year window. If the work is newly completed and handover is still pending, a new home handover inspection may also help identify defects before the next stage of the sale or occupancy process.
