VMIA and Victorian Domestic Building Insurance
Victorian Domestic Building Insurance. VMIA was the long-standing provider; since 1 July 2025 the Building and Plumbing Commission administers it. Cover responds when a builder dies, becomes insolvent, or disappears. Overall cap $300,000 per dwelling, with non-completion limited to 20% of the contract price and deposit refunds to 5%.
Definition
The Victorian Managed Insurance Authority (VMIA) was for many years the Victorian Government insurer behind the state's Domestic Building Insurance (DBI) scheme. Since 1 July 2025 the scheme has been administered by the Building and Plumbing Commission (BPC), which honours existing VMIA-issued certificates. DBI provides statutory protection for homeowners in Victoria where a residential builder dies, becomes insolvent, or disappears, and cover is mandatory for residential building work above a defined contract value threshold.
Why it matters
Domestic Building Insurance is the main statutory protection available to Victorian homeowners against builder failure, though it is designed as last-resort cover with caps and conditions below the contract value of most modern builds. Builders cannot legally take a deposit or commence residential work above the threshold without DBI cover in place. From 1 July 2026 Victoria moves from this last-resort model to a first-resort Home Warranty Scheme, so the rules below change again; confirm the current position with the Building and Plumbing Commission.
How it works in practice
The builder must hold DBI cover before taking a deposit or commencing work above the threshold. The builder pays the premium, and a certificate of insurance is issued for the specific job.
If the builder dies, becomes insolvent, or disappears, the homeowner can claim against the scheme. The overall cap is $300,000 per dwelling. Within that, deposit refunds are covered up to 5% of the contract price and non-completion up to 20% of the contract price, while defect claims can run up to the overall cap. There is no slab-pour activation trigger, and deposit cover applies once the policy is in place. The gap that hurt owners in past collapses was the required policy never being taken out, not deposits being excluded.
The claim process requires substantial documentation of the contract, payments made, work completed, and the basis for the claim. Claim lodgement deadlines apply (in Victoria, generally within 180 days of becoming aware of the insolvency), so lodge promptly. The scheme assesses the claim and either pays compensation or arranges for the work to be completed.
Common misconceptions
Domestic Building Insurance never covers my deposit
Deposit refunds are covered, up to 5% of the contract price, once the required policy is in place. The real risk is the builder never taking out the policy, in which case there is nothing to claim against.
$300,000 cover means I'll get $300,000
The cap is the maximum. The actual payout depends on the assessment of your specific loss, and non-completion claims are limited to 20% of the contract price. Many claims pay less than the cap.
I can lodge a claim whenever I get around to it
Claim lodgement deadlines apply (in Victoria, generally within 180 days of becoming aware of the insolvency). Lodge promptly and confirm the current deadline, because missing it can forfeit a valid claim.
The scheme covers all types of building work
It applies specifically to residential domestic building work above the threshold value. Commercial construction and certain categories of work are not covered.
