Quick Answer
Home warranty insurance (also called domestic building insurance or builder’s warranty) in Victoria is mandatory for residential building work over $16,000. It protects homeowners if their builder dies, disappears, or becomes insolvent before completing the work or within the warranty period. It does not cover general defects while your builder is still trading — for that, you rely on the building contract and the Victorian Building Authority complaints process.
What Is Home Warranty Insurance?
In Victoria, home warranty insurance is called domestic building insurance (DBI). It’s a mandatory insurance policy that builders must take out before accepting a deposit on residential building work worth more than $16,000. The policy protects you — the homeowner — not the builder.
The Victorian Building Authority (VBA) sets the rules. Your builder must be registered with the VBA to take out DBI. If your builder asks for a deposit without providing a certificate of insurance, that’s a legal red flag.
DBI is administered by the Victorian Managed Insurance Authority (VMIA). It’s not something you shop around for — there’s only one provider in Victoria, and the cost is embedded in your builder’s quote.
What Home Warranty Insurance Covers
DBI in Victoria covers you in three specific situations, all relating to the builder’s inability to complete the work:
- Insolvency — your builder goes bankrupt or enters administration
- Death or serious illness — the builder dies or becomes physically incapable
- Disappearance — the builder cannot be located after reasonable attempts
| Situation | What DBI covers | Limit (Victoria) |
|---|---|---|
| Incomplete work | Cost to complete construction to contract standard | Up to $300,000 |
| Structural defects (post-completion) | Major structural defects discovered after handover | Up to $300,000 |
| Non-structural defects | Defects in non-structural elements (plumbing, waterproofing) | Up to $300,000 |
What Home Warranty Insurance Does NOT Cover
DBI is specifically a last resort insurance — it only activates when the builder is gone. While your builder is still operating, DBI won’t help you.
| Situation | Covered by DBI? | What to use instead |
|---|---|---|
| Builder still trading but work is defective | No | Building contract dispute, DBDRV, VCAT |
| Builder refusing to fix defects in warranty period | No | VBA complaint, DBDRV mediation |
| Delays or cost overruns | No | Building contract, legal advice |
| Landscaping, driveways, fencing (separate contracts) | No | Separate contract dispute |
| Commercial buildings | No | Commercial insurance products |
| Owner-builder work | Limited | Owner-builder insurance (required for sale within 6.5 years) |
How Long Does the Cover Last?
| Defect Type | Warranty Period | Starts From |
|---|---|---|
| Structural defects (foundations, load-bearing walls, roof frame) | 6 years | Date of practical completion |
| Non-structural defects (waterproofing, plumbing, painting) | 2 years | Date of practical completion |
Owner-Builder Insurance: A Different Animal
If you’re building or renovating as an owner-builder in Victoria, if you sell your home within 6.5 years of receiving an owner-builder permit, you must take out owner-builder warranty insurance before listing. This protects the buyer, not you.
Owner-builder insurance requires an inspection report from a licensed building inspector. Budget $600–$1,200 for the inspection plus the insurance premium.
How to Make a Claim
- Confirm the trigger event — gather evidence that your builder is insolvent (ASIC search, liquidator letter), deceased, or has disappeared
- Contact VMIA — ring 1300 854 262 or visit vmia.vic.gov.au to lodge a claim
- Gather documentation — your signed building contract, Certificate of DBI, progress photos, invoices paid, permit documents
- Get a defect assessment — VMIA will arrange an independent building inspection to assess incomplete or defective work
- Receive settlement — VMIA negotiates with a completion builder or pays you directly for rectification
What to Do If Your Builder Has Defects But Is Still Trading
- Send a formal defects notice in writing citing the specific items and requesting rectification within 14–28 days
- Dispute Resolution Branch (DBDRV) — free mediation service at dbdrv.vic.gov.au
- VCAT — can order builders to rectify defects or pay compensation
- VBA complaint — file at vba.vic.gov.au if the builder is breaching the Building Act
Top 8 Tips and Gotchas
- Always get the certificate before paying a deposit. Your builder legally cannot take your money without providing a Certificate of DBI first.
- Check your builder’s registration at vba.vic.gov.au before signing anything.
- DBI does not cover tradesperson disputes. Individual trade contracts are separate — DBI only applies to the head building contract.
- Renovations over $16,000 are included. Extensions, bathroom renos, and kitchen renos of this value need DBI.
- Keep your practical completion date in writing. An email from your builder on handover day is sufficient evidence.
- Owner-builder insurance is for the buyer’s benefit. It protects the person you sell to — failing to get it makes your home very difficult to sell.
- Separate contracts may each need DBI. If you hire separate contractors for different trades, each contract over $16,000 may need its own DBI policy.
- Get legal advice for complex disputes. Building lawyers in Melbourne typically offer free 30-minute initial consultations.

Frequently Asked Questions
Do I need home warranty insurance for a kitchen or bathroom renovation?
Yes — if the work costs more than $16,000 in Victoria, your licensed builder must take out domestic building insurance (DBI) before accepting any deposit. This applies to renovations, extensions, and alterations, not just new builds.
My builder has gone bust. How do I make a claim?
Contact the VMIA on 1300 854 262 or via vmia.vic.gov.au. You’ll need your Certificate of DBI, signed building contract, proof of payments, and evidence of the builder’s insolvency such as a liquidator’s letter or ASIC company search.
Does home warranty insurance cover defects if my builder is still operating?
No. DBI only activates if the builder is insolvent, deceased, or missing. For defects while the builder is still trading, use the building contract dispute process, DBDRV mediation, or VCAT.
How much does domestic building insurance cost?
The cost is built into your builder’s quote — typically 0.4–0.6% of the contract value. Your builder must show the DBI levy on the contract documentation.
I’m selling my owner-built home — do I need special insurance?
Yes. If you received an owner-builder permit and are selling within 6.5 years of completion, you must obtain owner-builder warranty insurance before listing. A building inspection report from a licensed inspector is required first, costing $600–$1,200 plus the premium.
Final Thoughts
Home warranty insurance in Victoria is a safety net, not a guarantee. It protects you against the worst-case scenario — a builder who can’t finish or has disappeared — but it won’t help you resolve disputes with a builder who’s still operating. For that, you need a well-written building contract, clear scope documentation, and knowledge of the DBDRV and VCAT processes.
Before any building project in Melbourne or the SE suburbs, check your builder’s VBA registration, confirm their DBI certificate before paying a deposit, and keep a complete project folder throughout the build.
