What Is Domestic Building Insurance in Victoria?
If you’re planning a bathroom renovation, kitchen renovation or larger home improvement project, understanding Domestic Building Insurance (DBI) is just as important as choosing tiles, fixtures and finishes.
Many Victorian homeowners don’t realise that Domestic Building Insurance is a legal requirement for many residential building projects. Even fewer understand what it covers, when it applies, or how it protects them if a builder becomes insolvent, disappears, dies or is otherwise unable to complete or rectify building work.
With Victoria transitioning to a new Home Warranty Insurance system from 1 July 2026, homeowners now have access to stronger consumer protections than ever before.
Whether you’re preparing for a renovation or reviewing past building work, understanding your rights and responsibilities can help protect your investment and provide peace of mind throughout the construction process.
Are You Sure You Know What Domestic Building Insurance Looks Like?
Here’s a simple question that surprises many homeowners.
Have you ever actually seen your Domestic Building Insurance policy?
A common misconception is that DBI is a document produced by a builder. It isn’t.
Domestic Building Insurance is an official insurance policy issued through approved insurance providers and regulatory systems. A builder must arrange the insurance, but they do not create it themselves.
If you’ve completed domestic building work in recent years and cannot locate a certificate of insurance or copy of the policy, it may be worth reviewing your project documentation.
The insurance policy is one of the most important documents associated with your renovation, particularly if defects arise or you decide to sell your property in the future.
What Is Domestic Building Insurance?
Domestic Building Insurance, often referred to as DBI or builders warranty insurance, is a mandatory insurance scheme that protects Victorian homeowners in specific circumstances.
The insurance is designed to provide financial protection when a builder cannot meet their obligations under a domestic building contract.
Unlike standard building insurance, DBI does not cover every construction issue. Instead, it provides protection when a builder dies, disappears, becomes insolvent or is otherwise unable to rectify defective work or complete the project.
Domestic Building Insurance in Victoria applies to a wide range of residential building projects, including renovations, extensions, new homes and major domestic building work.
For many homeowners, DBI acts as a final layer of protection if serious problems occur and the builder is no longer available to resolve them.
When Is Domestic Building Insurance Required?
In Victoria, domestic building insurance is required for most residential building projects where the contract price exceeds the prescribed threshold.
Before commencing applicable building work, the builder must obtain the required insurance policy and provide the homeowner with the relevant documentation.
The builder must also provide a certificate of insurance before taking certain payments or commencing work.
This requirement exists to ensure homeowners have protection in place from the beginning of the project rather than after problems arise.
If you’re entering into a domestic building contract, it is important to confirm that the insurance policy has been arranged and that you have received copies of the required documentation.
What Does Domestic Building Insurance Cover?
Many homeowners assume the policy covers every possible building issue. In reality, DBI provides protection in specific situations where the builder can no longer fulfil their obligations.
Coverage may apply where a builder becomes insolvent, dies, disappears or otherwise cannot complete or rectify work.
Depending on the circumstances, the policy may help cover:
- Incomplete building work
- Defective building work
- Major structural defects
- Certain non-structural defects
- Financial losses arising from non-completion
- Other eligible costs associated with insured events
The exact coverage available will depend on the policy, the timing of the claim and the applicable legislation
What Are Structural and Non-Structural Defects?
Understanding the difference between structural and non-structural defects is important when discussing domestic building insurance.
Structural defects generally involve serious issues affecting the stability, safety or integrity of the building. Examples may include significant foundation movement, major waterproofing failures affecting structural elements or serious framing issues.
Non-structural defects typically involve building components that do not affect the overall structural integrity of the property. These may include certain finishing defects, installation issues or defects affecting the functionality of completed work.
Under the newer Home Warranty Insurance model, different coverage periods apply to structural and non-structural defects, providing greater clarity for homeowners.
How Does Home Warranty Insurance Change Things From July 2026?
From 1 July 2026, Victoria is introducing Home Warranty Insurance (HWI), administered through the Building and Plumbing Commission (BPC).
Home Warranty Insurance replaces the previous Domestic Building Insurance framework and expands consumer protections available to homeowners.
The updated scheme is designed to improve outcomes for Victorian consumers and provide broader protection when things go wrong during or after residential construction projects.
Key improvements include enhanced coverage provisions and clearer protections relating to incomplete or defective work.
For homeowners planning future renovations, the transition represents a significant improvement in how residential construction risks are managed.
What Happens If a Builder Becomes Insolvent?
One of the most common reasons homeowners search for information about domestic building insurance is concern about builder insolvency.
Unfortunately, construction businesses can encounter financial difficulties, and projects do not always proceed as planned.
If a builder becomes insolvent before completing a project or before rectifying defective work, homeowners can face substantial financial losses.
This is where builders warranty insurance becomes particularly important.
The insurance exists to provide protection in circumstances where the builder can no longer meet their contractual obligations. Without appropriate insurance coverage, homeowners may have limited options for recovering losses or completing unfinished work.
Does Domestic Building Insurance Protect My Deposit?
Deposits are often one of the biggest concerns for homeowners entering a renovation contract.
Depending on the circumstances and the applicable insurance arrangements, certain protections may apply where a builder becomes insolvent after receiving a deposit.
However, homeowners should always ensure deposits comply with Victorian building regulations and are paid under a properly documented domestic building contract.
Understanding how deposits are handled, what documentation should be provided and when insurance becomes effective can help reduce risk before work begins.
Why Is Domestic Building Insurance Important When Selling Your Home?
Many homeowners are surprised to learn that Domestic Building Insurance can remain relevant long after construction is complete.
If you sell a property within the applicable insurance period following major domestic building work, insurance documentation may be required during the sale process.
Potential purchasers often seek confirmation that appropriate insurance was obtained for the completed works.
If records cannot be located, the transaction process can become more complicated and may require additional investigation or documentation.
For this reason, homeowners should always keep copies of their policy and certificate of insurance in a safe place.
How Can You Check That Your Insurance Is Legitimate?
A genuine domestic building insurance policy should include official insurance documentation and a certificate of insurance associated with your project.
Homeowners should never rely solely on verbal assurances that insurance has been arranged.
Before work begins, ask your builder to provide copies of the relevant documentation and ensure the details correspond with your project and contract.
A registered builder should be able to explain the insurance process clearly and answer any questions regarding coverage and compliance requirements.
