Dilapidation Reports in NSW: What the Law Says and What Builders Must Know

Many builders in New South Wales are unsure about their legal obligations when it comes to dilapidation surveys. Is it required by law? Who is responsible? What happens if something goes wrong? This post breaks it all down.

Is a Dilapidation Report Legally Required in NSW?

In New South Wales, a dilapidation report is not universally mandated by statute for all construction projects. However, there are several circumstances where it is effectively required or strongly expected.

Under many development consent conditions issued by local councils, dilapidation surveys of adjoining properties are required before construction commences. This is particularly common for projects involving excavation deeper than 1 metre near a boundary, demolition works, or piling and underpinning.

Additionally, the Environmental Planning and Assessment Act 1979 and associated regulations create obligations around protecting neighbouring properties from construction-related damage. While the Act does not prescribe dilapidation reports specifically, failing to document pre-existing conditions can significantly weaken your legal position if a neighbour pursues a claim.

Common Law and Negligence

Even without a specific statutory obligation, construction companies can be held liable under common law negligence if their works cause damage to neighbouring properties. The burden of proof in these cases often falls on the party being claimed against — meaning that without a pre-construction dilapidation report, you may struggle to demonstrate that damage was pre-existing.

What Does a Compliant Dilapidation Report Look Like?

A proper dilapidation report should include the date and time of the inspection, the name and contact details of the surveyor, photographs of all relevant areas with clear labelling, written descriptions of observed conditions (including any pre-existing damage), and a floor plan or site map showing which properties were surveyed.

Reports should be retained for the duration of the project and for a reasonable period afterwards, as disputes can arise after completion.
