Owner-Builder Obligations
in Victoria
A comprehensive legal reference for vendors and practitioners navigating the complex obligations under section 137B of the Building Act 1993 (Vic) — covering structural and cosmetic works, Section 32 disclosure requirements, insurance, and the consequences of non-compliance.
Critical: Failure to comply with s137B before the purchaser enters into a contract of sale gives the purchaser the right to void the contract at any time prior to settlement — including at the eleventh hour. These obligations cannot be contracted out of.
Navigating the Labyrinth
Acting for vendors who have undertaken building works on their property is one of the most legally complex areas of Victorian property law. The obligations imposed by section 137B of the Building Act 1993 (Vic) are strict, non-negotiable, and carry severe consequences for non-compliance. Whether the works are structural renovations or seemingly minor cosmetic alterations, the vendor's obligations may be triggered — and failure to comply can result in a purchaser voiding the contract right up until settlement.
This reference guide is designed to assist legal practitioners and vendors in understanding the full scope of these obligations, including the nature of the works that trigger them, the applicable cost thresholds, the prescribed timeframes, and the mandatory disclosure requirements for the Section 32 Vendor Statement.

The Works
Any domestic building work carried out by or on behalf of the owner, where the owner has not engaged a registered builder under a major domestic building contract for the entirety of the work.
The Timeframe
Works completed within the prescribed period — generally 6.5 years from the date an Occupancy Permit or Certificate of Final Inspection was issued, or 7 years from the building permit date if no such certificate was issued.
The Obligations
Before entering into a contract of sale, the vendor must provide: (1) a defects inspection report not more than 6 months old; and (2) if works exceed $16,000, evidence of Domestic Building Insurance.
