Builders warranty insurance exemptions in Victoria

What it is

Domestic Building Insurance (DBI) is the last resort insurance scheme that protects Victorian homeowners against incomplete or defective building work where the registered builder has died, disappeared or become insolvent. It is required for major domestic building contracts above a prescribed threshold and is governed by the Ministerial Order under section 135 of the Building Act 1993. From 1 July 2025 the scheme is administered by the Building and Plumbing Commission, before that date it sat with the Victorian Managed Insurance Authority. The same Ministerial Order continues to apply.

The Ministerial Order sets the price threshold, the building types in scope and the categories of work that are excluded from cover. Builders who take payment under a major domestic building contract without first holding DBI face penalties exceeding $46,000 for individuals and $480,000 for companies under section 137. The exemptions matter because they define the projects where a builder does not need to issue a Certificate of Insurance and is not exposed to the section 137 penalty.

The $16,000 contract value exemption

DBI is required only where the contract price is more than $16,000. Below this threshold the work is excluded from the scheme. The exemption applies to the total contract price, not the value of any single trade item. A $14,000 bathroom renovation is exempt, however the parties cannot split a $25,000 kitchen renovation into a $13,000 cabinetry contract and a $12,000 tiling contract to avoid the requirement. Consumer Affairs Victoria treats artificial contract splitting as a single composite contract and applies the threshold to the aggregate.

The threshold has not been indexed since the scheme was rewritten and now captures a far smaller share of work than originally intended. Most full bathroom or kitchen renovations and almost all new dwelling contracts sit well above the threshold. Builders working in the cosmetic renovation and small repair market sit predominantly below it.

The multi-storey exemption

DBI is not required for multi-storey residential buildings containing more than three storeys of accommodation. The exemption is set out in Practice Note PN-01 issued by the Victorian Building Authority and reflects the Ministerial Order treatment of larger Class 2 buildings.

The boundary is precise. A rise in storeys of three with three Class 2 storeys requires DBI. A rise in storeys of four with four Class 2 storeys does not. An entrance foyer and storage area count as accommodation even where the rest of the floor is given over to carparking. The exemption attaches to the building as a whole, not to individual units, so a builder contracting for a single apartment in a five storey block is exempt regardless of the contract value.

Why the multi-storey carve-out exists

The Ministerial Order treats larger Class 2 buildings as commercial-grade risk that sits outside the consumer protection model DBI was built to deliver. Owners corporations in higher-rise buildings rely on the implied warranties under section 8 of the Domestic Building Contracts Act 1995 and the warranty rights transferred through successor purchasers under section 9. The Cladding Rectification Program funded by the State picks up the catastrophic failure cases the DBI scheme would otherwise have needed to absorb.

Other categories outside DBI cover

DBI is not required for work carried out by an owner-builder for their own home, for work performed by the consumer on their own home, for repairs and maintenance under the contract threshold and for fences, retaining walls and similar work where the value sits below the threshold or where the work falls outside the definition of domestic building work. Plumbing work is covered by a separate insurance regime under Plumbing Industry Commission rules and does not attract DBI even where the contract value exceeds $16,000.

A new dwelling contract above $16,000 always requires DBI regardless of the trade composition. A renovation contract above $16,000 to an existing single dwelling requires DBI in the same way. A renovation contract above $16,000 to a unit inside a Class 2 building with four or more storeys is exempt because the multi-storey rule overrides the threshold.

TradeLens compliance signal

For TradeLens clients the DBI exemption framework is one of the highest risk patterns in the platform. Builders who misread the multi-storey exemption commonly take a deposit on a contract that legally required DBI. Builders who rely on the $16,000 threshold for a renovation that grows through variations into a contract above the threshold create the same exposure if the original Certificate of Insurance was never issued. TradeLens compares the live contract value against the threshold and the building classification against the exemption matrix on every project update.
