Decennial Liability Insurance (DLI) is an NSW scheme designed to provide long-term protection against serious defects affecting critical structural elements in qualifying apartment buildings over three storeys.
DLI provides protection for up to 10 years and operates on a first-resort, strict-liability basis. This means an owners corporation does not have to establish that the developer or builder was at fault before making a claim.
Because the policy is legally attached to the building itself, protection for the strata owners remains fully active even if the original building entity or development company goes insolvent or ceases trading.
While the Strata Building Bond requires developers to lodge a 2% financial security bank bond to catch early defects, DLI is a comprehensive insurance policy providing much longer-term protection. Under current NSW guidelines, developers can choose DLI as an alternative pathway to the SBB. *Note: The planned statutory increase of the SBB from 2% to 3% has been officially deferred until 1 July 2028.
| Feature | Strata Building Bond (SBB) | Decennial Insurance (DLI) |
|---|---|---|
| Nature | Statutory Bank Security / Bond | 10-Year Insurance Policy |
| Fault Basis | Statutory inspection & claim process | Strict-Liability / First-Resort |
| Insolvency | Limited to value of cash bond | Full insurer backing if trader closes |
A key advantage of the DLI framework is active underwriting intervention. Insurers run exhaustive technical checks, engineering site checks, and building history reviews *during* the active construction phase to minimize risk before backing the asset. This creates a strong commercial incentive for builders to maintain flawless standards.
