What Is a Dilapidation Report?
A dilapidation report is a detailed record — photographs, written notes and sometimes measurements — of the condition of a neighbouring property, taken before construction work starts nearby. It exists to establish a fair, evidenced baseline, so if a crack or damaged fence appears during the job, everyone can tell whether construction caused it or it was already there. Councils and adjoining owners increasingly ask for one before excavation or demolition begins close to a boundary.
Key takeaways
- A dilapidation report is a dated photographic and written record of a neighbouring property’s condition, taken before nearby construction begins.
- It exists to give an evidenced baseline, so any damage claim during construction can be checked against what already existed.
- Councils commonly require one as a condition of consent for excavation, demolition or vibration work near a boundary.
- An independent surveyor, engineer or consultant should prepare it, with the neighbouring owner’s agreement for access.
What is a dilapidation report and why it exists
A dilapidation report is a factual, timestamped record of an existing structure’s condition — cracks, settlement, damaged finishes, fences and retaining walls — captured before nearby construction begins. It is not an opinion on whether a building is safe; it is evidence of what state a property was in on a given date, so a later damage claim can be checked against it rather than argued from memory.
When a dilapidation report is required
Requirements vary by council and state, but a dilapidation report is commonly required, or recommended, whenever work involves excavation, piling, demolition or vibration close to a shared boundary. Many development consents in NSW and other states include a condition requiring surveys of adjoining properties. Even without a formal condition, a sensible builder arranges one anyway — it is far cheaper than a disputed damage claim later.
- Basement excavation, underpinning or shoring near a boundary.
- Demolition next to an occupied neighbouring property.
- Piling, rock breaking or other vibration-heavy work.
- Any consent condition that specifically requires it.
Who prepares a dilapidation report
A dilapidation report is normally prepared by an independent building surveyor, structural engineer or specialist consultant — independence matters, since the report has to be credible to both parties if a dispute arises. The surveyor photographs and documents the property, noting existing cracking or damage in enough detail to stand up months later. Access is by agreement with the owner, so approach them early and keep a copy available to both sides.
What a dilapidation report typically covers
A useful report goes well beyond a couple of snapshots. It typically records:
- Dated, referenced photographs of external walls, fences, driveways and retaining structures.
- Internal condition where access is agreed — cracking, cornice separation, door and window alignment.
- Written notes describing existing defects, their size and location.
- The scope of nearby works and the survey date, tying it to a point before construction started.
How My Trade Hub fits in
My Trade Hub does not produce dilapidation reports — that is independent surveying work, kept separate from the builder for good reason — but it does help you price and document the works that trigger the need for one. Where a tender includes excavation, demolition or shoring near a boundary, the automated quantity takeoff measures those items from your plans, and the editable rates library lets you build an allowance for the survey into the priced tender as its own line. Creating an account is free; estimating and tender preparation sit on the paid Starter, Scale and Professional plans (AUD, no lock-in contracts).
Frequently asked questions
Who pays for a dilapidation report?
The party carrying out the nearby construction — usually the builder or developer — typically commissions and pays for it, since it protects them as much as the neighbouring owner.
Is a dilapidation report a legal requirement?
It depends on the council and job. Many consents include a condition requiring surveys for excavation or demolition near a boundary, but it is not universally mandated, so check the specific conditions.
What happens if a dilapidation report is not done and damage occurs?
Without a pre-construction baseline, it becomes far harder to prove whether damage was caused by nearby construction or already existed, which can turn a simple repair into a costly dispute.
How long does a dilapidation report take?
It varies with the property’s size, but a single survey is typically a same-day site visit, with the written report following within a few business days once access is agreed with the neighbouring owner.
