Do You Need a Dilapidation Report in Melbourne? When It Is Required
Not every construction project requires a dilapidation report, but many do. Here is a clear breakdown of when a report is mandatory, when it is recommended, and when you can safely skip it.
When a Dilapidation Report Is Mandatory
In the following situations, a dilapidation report is either explicitly required or effectively unavoidable:
Council Permit Condition
The most common mandatory trigger. Many Melbourne councils include dilapidation report requirements in planning and building permit conditions for multi-dwelling developments, commercial builds, basement excavations, and demolition projects. If the permit says a report is required, it is not optional.
Government Infrastructure Projects
Major road, rail, and tunnelling projects in Victoria (Metro Tunnel, North East Link, West Gate Tunnel, level crossing removals) include dilapidation surveys as a standard project requirement. The project authority arranges and funds these reports.
Insurance or Contract Requirements
Some building contracts and insurance policies require dilapidation reports as a precondition. Public liability insurers may require evidence that existing conditions were documented before works commenced.
When a Report Is Recommended but Not Mandatory
Even when there is no formal requirement, a dilapidation report is strongly recommended in these scenarios:
- Neighbouring property undergoing significant renovation— Extensions, additions, or underpinning works can affect your property even without a council-imposed requirement
- Your property is older or heritage-listed— Older buildings are more susceptible to vibration and ground movement. Even minor construction activity can cause cracking in heritage masonry
- You are in a high-risk soil area— Melbourne’s reactive clay soils amplify the effects of ground disturbance. Properties in eastern and south-eastern suburbs are particularly vulnerable
- You have concerns about a specific property— Existing structural issues, previous subsidence, or known drainage problems make documentation even more important
- Commercial lease obligations— Tenants may need to document the condition of leased premises to protect against end-of-lease disputes
When You Probably Do Not Need One
A dilapidation report is unlikely to be necessary when:
- Nearby construction is minor (e.g., a garden shed, single-storey extension on a distant lot, or cosmetic renovation)
- The construction is far enough away that ground disturbance and vibration will not reach your property (typically more than 50 metres for standard residential works)
- The works involve no excavation, piling, or demolition
- Your property and the construction site are separated by a road or other buffer
When in doubt, it is always safer to have a report than to wish you had one after damage appears. The cost of a dilapidation report is modest compared to the cost of repairing unproven construction damage. See our cost guide for current pricing.
