You buy the policy.
The homeowner holds the cover.

DBI is issued by the Building and Plumbing Commission (BPC), the Victorian Building Authority trading as BPC, as a designated insurer under the Building Act 1993 (Vic). It is compulsory for domestic building work above the prescribed contract-value threshold, and the builder must have the certificate of insurance in place for the job. Confirm the current threshold and procedural requirements with the BPC, as these settings are updated over time.

The structure surprises builders who haven’t read the wording: the insured is the home owner and any successor in title, and the builder, speculative builder and developer are expressly excluded from that definition. You buy a policy that protects someone else, against you failing. Cover also travels with the home: a purchaser who buys within the cover period inherits the protection.

Last resort: the four triggers

Victorian DBI is last-resort cover. It responds only where the builder cannot answer for the work, not whenever a defect or dispute arises. The four trigger events are that the builder (or speculative builder) has died, disappeared, become insolvent, or failed to comply with a Tribunal or Court order. The fourth trigger is narrower than it sounds: appeal periods must have expired, a written demand must have been served, and more than 28 days must have passed without compliance. In an ordinary dispute with a solvent, contactable builder, the policy does not respond, and the builder remains directly liable. That is worth being plain about with clients, so nobody mistakes the certificate for a general guarantee.

Limits, periods and excesses

• Aggregate limit: $300,000 per home for all claims, inclusive of the reasonable legal costs of a successful claim.
• Non-completion: capped at 20 per cent of the building contract price, adjusted for agreed variations. This is a cap on incomplete-work claims, not a separate pool.
• Periods: non-structural defects are covered until two years after completion (or termination, whichever is earlier); all other loss, including structural defects, is covered for six years. Periods run from the commencement date, which the policy defines as the earlier of the building contract date and the building permit issue date.
• Excesses: none for non-completion claims or for loss arising up to three months after completion, then scaling with the age of the claim, up to $1,000 for claims made more than five years out.
• Notification: the homeowner must notify a claim in writing within 180 days of becoming aware of the trigger event, or of when they reasonably should have been aware.

These figures come from the policy wording applying to certificates of insurance issued on or after 1 July 2025, under the Domestic Building Insurance Ministerial Order of February 2024. Check the wording that applies to the certificate date in question before relying on any figure.

One more clause builders should know

If the builder breaches its duty of disclosure or good faith to the insurer, the BPC will not refuse the homeowner’s claim, but it may recover from the builder. In other words, the homeowner’s protection holds, and the consequences route back to you. Accurate declarations and clean paperwork are not just compliance hygiene; they are what stands between a paid claim and a personal recovery action.

For how Victoria compares with the other states’ schemes, see our state-by-state home warranty guide, and for the NSW equivalent in depth, the HBCF eligibility guide. Because eligibility for cover is underwritten against your financial position in every scheme, the balance-sheet mechanics in our Open Job Value guide apply in Victoria as much as anywhere.

Nothing in software changes the scheme. What software changes is whether the records the scheme runs on exist when you need them. Every pressure point above is documentary: proving what the contract price was after variations, showing what was built and when, holding the certificates and inspection records across a six-year tail, answering a claim assessor from files rather than memory.

A platform that documents variations as they are approved, keeps costs and claims tied to the job, and holds the job’s documents in one place is quietly building your DBI defence file as a by-product of normal work. The alternative is reconstructing a 2020 job’s history in 2026, from three ex-employees’ inboxes, under a claim deadline.
