137B Owner Builder Defects Inspections (Victoria Only)

Understanding Section 137B of the Building Act 1993
The Building Act 1993 is a cornerstone of Victoria’s construction regulations, ensuring that all building projects meet strict safety, quality, and compliance standards. Within this legislative framework, Section 137B plays a critical role in protecting property buyers from defective or substandard building work. It applies primarily to owner-builders who have completed renovations, extensions, or other significant building works and wish to sell the property within 6.5 years of completion. The law requires these sellers to disclose key information about the condition of the property, ensuring transparency, reducing disputes, and maintaining construction quality.

Key Requirements and Obligations
Under Section 137B, owner-builders must obtain a Defects Inspection Report from a registered building practitioner before selling their property. This report must assess the structural integrity of the work, identify any defects or incomplete work, and confirm compliance with Australian building standards. In addition, if the value of work exceeds $16,000, Domestic Building Insurance must be obtained to protect the buyer against losses from structural defects or incomplete projects. Failure to comply can result in substantial fines from the Victorian Building Authority (VBA), contract termination, and potential legal claims from buyers.

Who Must Comply and Applicable Exemptions
The requirements of Section 137B apply specifically to owner-builders, while licensed builders are exempt from providing a Defects Inspection Report when selling, as they are already subject to other regulatory obligations. Real estate agents involved in the sale of an owner-built property also have a responsibility to ensure compliance, as selling without the required documentation can result in legal liability. Buyers are strongly encouraged to request an S137B report to safeguard their purchase. Exemptions under the Act include minor cosmetic works such as painting, flooring, or cabinetry, as well as certain commercial property classifications.

Importance of Compliance and Enforcement
The Victorian Building Authority actively enforces compliance with Section 137B through audits, inspections, and investigations of complaints. The Defects Inspection Report must be prepared no more than six months before the sale and is a vital tool in ensuring buyers make informed decisions. Non-compliance not only risks severe financial penalties but can also result in contract rescission, requiring sellers to refund the purchase price. By engaging a qualified building practitioner and securing the necessary insurance, owner-builders can meet their obligations, protect their investment, and ensure a smooth, legally compliant property transaction.
