TL;DR

Domestic Building Insurance (DBI) is mandatory for registered domestic builders contracting work over $16,000 in Victoria. Get the certificate before touching any money, including the deposit. Cover pays to the homeowner only on four trigger events: builder death, insolvency, disappearance, or failure to comply with a VCAT/court order. Maximum cover is $300,000 (policies from 1 July 2014): six years for structural defects, two years for non-structural. The Building and Plumbing Commission (BPC) is the sole provider since 1 July 2025. From 1 July 2026, the scheme shifts to first-resort: homeowners can claim even with the builder still trading, and the threshold rises to $20,000 (verified 2026-05-10, Building Legislation Amendment (Buyer Protections) Act 2025).

In plain English

DBI is Victoria’s statutory home warranty product. It protects homeowners when a builder cannot complete or rectify residential work because of a defined failure event. Until 30 June 2026 it is last-resort: no claim is available while the builder is still trading and contactable.

The BPC has been sole provider since 1 July 2025, absorbing the Victorian Managed Insurance Authority’s (VMIA) DBI function. VMIA held the role from 2010 following reforms that ended the previous multi-provider model (verified 2026-05-10, VBA, Understanding domestic building insurance).

What it requires

Who must obtain cover

A registered domestic builder must hold a Certificate of Insurance for domestic building work in Victoria where the contract price exceeds $16,000. Applies to new dwellings, renovations, extensions, swimming pools, and garages. The certificate must reach the homeowner before any payment is accepted, including the deposit. Taking a deposit first is an offence.

Only a registered domestic builder can purchase DBI. Unregistered persons cannot take on contracts over $10,000.

Multi-storey exemption: buildings of more than three storeys containing two or more dwellings are exempt by Ministerial Order (verified 2026-05-10, Consumer Affairs Victoria, Domestic building insurance).

Coverage amounts

Policy dateMaximum coverIncomplete works cap
On or after 1 July 2014$300,00020% of contract price
Before 1 July 2014$200,00020% of contract price

The 20% cap on incomplete works is a separate limit within the total. Defect rectification is funded from the same pool. Cover transfers to purchasers on sale of the property.

Coverage periods

Defect typePeriod
Structural defects6 years from practical completion or contract end
Non-structural defects2 years from practical completion or contract end

The Building Act 1993 (Vic) also provides a separate 10-year limitation period for latent defect claims that runs independently of DBI windows (verified 2026-05-10, HIA Insurance Services, Domestic Building Insurance VIC).

Trigger events (current, until 30 June 2026)

Trigger eventNotes
Builder deathIndividual builder dies before completion or rectification
Builder insolvencyLiquidation, bankruptcy, or administration
Builder disappearanceBPC confirms builder cannot be located
VCAT or court order non-compliancePolicies issued on or after 1 July 2015 only

Homeowners have 180 days from becoming aware of the trigger event to notify the insurer (verified 2026-05-10, LC Lawyers, An overview of DBI in Victoria).

From 1 July 2026: first-resort scheme

The Building Legislation Amendment (Buyer Protections) Act 2025 reshapes DBI from 1 July 2026:

  • Claims available for incomplete, defective, or non-compliant work, even with the builder still trading.
  • No dispute resolution required before claiming.
  • Threshold rises from $16,000 to $20,000.
  • Scheme applies to buildings of three storeys or less.
  • Coverage is automatic; homeowners are protected whether or not the builder has paid the premium.

(verified 2026-05-10, Norton Rose Fulbright, Building Legislation Amendment (Buyer Protections) Bill 2025 passed)

Expect substantially higher premiums post July 2026 as insurer exposure widens from last-resort to first-resort.

Letter of Eligibility (LOE)

Before buying a DBI certificate for any project, a builder needs a current Letter of Eligibility from the BPC. The LOE sets the builder’s financial capacity for DBI work.

Key points:

  • Annual construction limit: aggregate value of concurrent DBI-covered projects allowed at any time.
  • Category limit: maximum value for a single project.
  • Financial assessment: net tangible assets, turnover, profit margins, cash flow, working capital.
  • Obtained via: the BuildVic portal (buildvic.vic.gov.au).
  • Registration gate: BPC will not renew a Domestic Builder registration without current DBI eligibility.

Premium calculation

DBI premiums are a percentage of the total contract price. The BPC sets rates; approved distributors (HIA Insurance Services, MBIB) issue certificates via the BuildVic portal. Rates increased significantly following the 2022-2024 builder insolvency wave:

Price premiums into your estimate and tender. Do not absorb them.

Owner-builders

Owner-builders completing work over $16,000 must obtain DBI before selling the property within 6.5 years of practical completion, under section 137B of the Building Act 1993 (Vic). Their DBI obligation is on sale, not on construction. The certificate must be disclosed to the purchaser (verified 2026-05-10, Consumer Affairs Victoria, Domestic building insurance).

What DBI doesn’t cover

  • Work below $16,000 (rising to $20,000 from 1 July 2026)
  • Commercial building work
  • Buildings over three storeys containing two or more dwellings (Ministerial Order exemption)
  • Disputes with a solvent, contactable builder (until 1 July 2026)
  • Incomplete works beyond 20% of the contract price
  • Defects from owner misuse, maintenance failure, or pre-existing conditions
  • Work by an unregistered person

Penalties

Obtaining money before providing DBI is an offence under the Building Act 1993 (Vic):

  • Individuals: fines exceeding $46,000
  • Companies (knowing or reckless non-compliance): fines up to $480,000

(verified 2026-05-10, BPC, Domestic building insurance for builders)

Practical implications

For builders: sequence is LOE confirmed, certificate issued on BuildVic, certificate provided to owner, deposit accepted, work commences. Maintain your LOE financial position or the next certificate gets blocked. From July 2026, first-resort exposure is broader; LOE and registration requirements remain.

For homeowners: confirm the builder is registered and LOE-current before signing. Confirm the DBI certificate is in your name before paying the deposit. DBI is last resort until July 2026; defect disputes with a trading builder go through statutory warranties and VCAT first. From July 2026, claim directly.
