What is Domestic Building Insurance (DBI) in Victoria?

Domestic Building Insurance (DBI) is compulsory statutory insurance for every Victorian domestic build over $16,000, issued through the Victorian Managed Insurance Authority (VMIA) and administered by the VBA. It covers you if your builder dies, disappears, becomes insolvent or is deregistered, up to $300,000 for a single dwelling. Ask for the job-specific DBI certificate BEFORE paying a deposit - no cert = illegal build.

What DBI covers

DBI is a last-resort insurance policy. It only pays out when the builder dies, disappears, becomes insolvent or is deregistered by the VBA - AND you have suffered actual financial loss. Coverage: up to $300,000 per dwelling ($3M for apartment buildings). Non-completion of the build, structural defects up to 6 years post-handover, non-structural defects up to 2 years. Does NOT cover: normal contract disputes, cosmetic disagreements, delays, cost blowouts, or if you cancel the contract yourself.

How to verify the DBI cert

Ask the builder for the DBI certificate specific to your job (with your name and address, not just a company statement). Cross-check on the VMIA portal (vmia.vic.gov.au) - some builders forge certs. Confirm the cover amount matches your contract price. Never pay a deposit without seeing the cert. If the builder resists, walk away - it means either they cannot get cover (a red flag) or they are trying to skip the statutory requirement.

DBI vs HBCF (South Australia)

DBI is Victoria's equivalent of South Australia's Home Building Compensation Fund (HBCF), NSW's Home Building Compensation Fund and QLD's Queensland Home Warranty Scheme. All are last-resort insurance schemes. DBI's $300k cap is above the SA HBCF cap ($150k until 2023, now $340k). All schemes exclude "willful misconduct" by the buyer - keep contract communications professional.

What happens when a Victorian builder collapses

The Porter Davis collapse in April 2023 exposed a major gap: many buyers had paid deposits but their DBI certs had not been issued yet. VMIA responded with the "Porter Davis Home Buyers Support Package" - full DBI coverage extended retroactively. Since then, VBA has tightened the rule: builders MUST issue the DBI cert before taking a deposit. This is the single most important protection Victorian buyers have.

Frequently asked

How much does DBI cost?

DBI is paid by the builder (baked into the contract price) at roughly 0.4-1.0% of the contract value, so around $2,000-$5,000 on a typical $500,000 domestic build. You do not pay it directly - but always confirm the cert has been issued in your name before your deposit is handed over.

Does DBI cover renovation work?

Yes - any Victorian domestic building work over $16,000, including renovations, extensions and knockdown-rebuilds. Applies to both fully-managed builds and owner-builder projects (where the DBI is your responsibility to arrange).

How do I claim on DBI?

Contact VMIA directly (vmia.vic.gov.au or 1300 552 072) once you know the builder has died, disappeared, become insolvent or been deregistered. Provide the DBI cert, your contract, evidence of payment and evidence of the trigger event. Claims typically resolve in 3-9 months. VMIA will either arrange for another builder to finish the job or pay out the difference to your policy limit.
