Eligibility & Responsibilities
Am I a building owner?
An owner-builder is someone who takes on the responsibility of domestic building work on their own land. In Victoria, if you have constructed a home or managed significant renovations without a registered builder, you are legally classified as an owner-builder. This status comes with critical responsibilities, especially when selling. You must ensure all works comply with the Building Act 1993 and provide a Section 137B report if selling within 6.5 years of completion.
- Obtaining all necessary building permits and insurance.
- Ensuring all work meets Victorian building standards.
- Providing a Section 137B Defects Report to prospective buyers.
- Managing all sub-contractors and site safety requirements.

Frequently Asked Questions
What is a Section 137B Defects Inspection?
A Section 137B inspection (also known as an Owner-Builder Inspection) is a mandatory requirement under the Victorian Building Act 1993 for anyone who has carried out domestic building work as an owner-builder and intends to sell their property within six and a half years of completing that work.
Why is this inspection legally important in Victoria?
The inspection provides a clear record of the condition of the works at the time of sale. Without a valid Section 137B report included in the Section 32 (Contract of Sale), the vendor may find the contract voidable by the purchaser, potentially delaying or collapsing the sale.
What is typically covered in the inspection report?
Our surveyors document all defects, incomplete works, and second-hand materials used. The report details structural integrity, finishing quality, and compliance with the Victorian Building Regulations, providing transparency for both the seller and the prospective buyer.
How long is the Section 137B report valid?
The report must be no older than six months at the time the contract of sale is signed. If your property remains on the market longer, a reinspection might be necessary to ensure the continuous validity of your documentation.
