🔍 What Is a 137B Owner Builder Defect Report?
A 137B report is a legally required document for any owner‑builder who has carried out building work valued at more than $16,000 within the past 6.5 years. It must be provided to potential buyers before a contract of sale is signed.
The report:
- Identifies all visible defects
- Assesses structural and non‑structural issues
- Documents incomplete or unsafe work
- Helps buyers understand the condition of the property
- Supports warranty insurance requirements
- Ensures transparency during the sale process
Without a valid 137B report, the sale of your property may be delayed or legally challenged.
