Quick answer: A dilapidation report is an independent record of a property's condition at a set point in time. It is taken before nearby construction work begins. The report uses photos and notes to document existing damage like cracks and movement. If new damage shows up later, the report proves what was already there. This protects both the property owner and the builder.

An excavator rolls in next door. You spot survey pegs down the street. It is fair to wonder what all that digging might do to your home. Heavy machinery and vibration travel further than most people expect. A small crack you never noticed can suddenly look suspicious. The hard part is proving whether that crack is new or old.
A dilapidation report solves this. It is a dated record of your property’s condition before the works start. Both sides can refer back to it if a dispute comes up. This guide covers what a dilapidation report involves. It also explains when you need one, what it costs and how the rules work in Victoria.
Key Takeaways:
- A dilapidation report documents a property’s existing condition before nearby construction begins.
- It protects both the property owner and the builder from damage disputes.
- You need one before major projects like excavation, demolition and piling.
- In Victoria, the Building Act 1993 and council permits can make a report part of approval.
- A qualified building inspector should carry it out, never the builder doing the work.
What Is a Dilapidation Report (and What It Isn't)?
A dilapidation report is a detailed inspection of a property’s condition at one point in time. A qualified building inspector prepares it. You might also hear it referred to as a property condition report or a dilapidation survey. These are the same documents.
The goal is simple. The report creates a baseline before any nearby construction work begins. It records existing defects such as cracks, water stains and uneven paving. Photos back up every finding. Later, that baseline makes it easy to tell new damage from old.
A dilapidation report is different from a building inspection. A building inspection looks for defects that might affect a purchase. A dilapidation report records the condition of a property before the works next door start. One helps a buyer decide. The other protects you with evidence. Ripple’s dilapidation report service is built for that second job.
Why Dilapidation Reports Matter
The value shows up the moment someone points at a crack. They want to know who is responsible.
For property owners, the report means you will not pay for damage caused by someone else’s construction project. For the builder, it works the other way. The report protects builders from false or inflated claims. Because it is independent and dated, it turns a messy argument into a question of fact. That tends to keep neighbour relations civil too.
This matters because there is a lot of building going on. In March 2026, Victoria recorded the highest number of dwelling approvals of any state. That was 5,102 dwellings in a single month, according to the Australian Bureau of Statistics. Add major infrastructure projects on top of that. The odds of living near active work are high. A dilapidation report is cheap insurance against an expensive dispute.
When Do You Need a Dilapidation Report?
You do not need one for every job nearby. They matter around major construction projects and ground works. Think excavation, demolition and deep digging. Piling, vibration and heavy machinery count too. Road and rail works, basement digs and large developments all qualify. Pipe-laying and major utility work can also affect neighbouring buildings.
Across Melbourne and Geelong, this is common. Big Build projects like the Suburban Rail Loop and level-crossing removals put many homes close to serious earthworks. Infill development adds more. Proximity alone often justifies a report. If works happen close to a shared boundary, even a routine job can shift soil and shake foundations.
Is a Dilapidation Report Required in Victoria?
Here is the part that interstate guides skip.
No single national law forces a dilapidation report in every case. The requirement usually comes from two places. Councils set it as a condition of development approval. Victoria’s building law also plays a role.
Under the Building Act 1993, an owner planning work that requires protection must first notify the affected neighbour. The condition of the adjoining property can be surveyed and recorded as part of that step. In practice, that record is a dilapidation survey. The Victorian Building Authority oversees these protection work rules. It flags excavation and work near boundary walls as common triggers.
The law also protects the neighbour. A builder doing protection work must hold insurance that covers damage to the adjoining property. That cover runs for a period after the work ends. For residential builds, the Domestic Building Contracts Act 1995 adds further duties on builders. Many inner Melbourne councils also require a pre-construction record for medium and large developments. Heritage buildings get extra attention.
So even when a report is not strictly required, the system assumes a baseline exists. Having one puts you in a stronger spot.
What's Included in a Dilapidation Report?
A dilapidation report covers the full condition of a property before nearby construction or excavation begins. The inspection documents existing damage with written notes and photographic evidence so any future changes can be clearly identified.
What’s typically included in a dilapidation report:
- Cracks in brickwork, render, walls and paving
- Roofs, gutters, fences and retaining walls
- Signs of ground movement or structural stress
- Load-bearing walls and structural elements
- Internal cracks in ceilings, floors and walls
- Window and door frames, especially near wet areas
- Garages, sheds, driveways and pools
- Detailed photos showing the location and size of defects
A quality report creates a clear record that can be referenced months later if disputes arise. The completed report is signed by the inspector and shared with the relevant parties for future reference.
The Dilapidation Report Process
Arranging a report is simple. A good inspector follows the same steps each time. You can see how Ripple conducts its inspections to get a sense of the flow.
The dilapidation report process follows a clear step-by-step approach. A qualified inspector documents the property’s condition before nearby construction begins. This creates a reliable baseline if damage claims arise later.
Step 1: Book the Inspection
The process starts by arranging the inspection before any construction, demolition or excavation work begins. You provide the property details, project information and preferred timeline.
Step 2: Complete the On-Site Inspection
The inspector visits the property and records its existing condition in detail. They photograph visible defects, including small issues such as hairline cracks, wall movement, or damaged paving. Internal and external areas are both assessed.
Step 3: Receive the Dilapidation Report
The completed report is usually delivered within one or two business days. It includes written observations, clear photographic evidence and documented defect locations. The report is designed to be easy to read and reference later if needed.
Step 4: Conduct a Post-Construction Inspection
Once the nearby works finish, the inspector can return to compare the property against the original report. This follow-up inspection helps identify any new damage or structural movement that may have occurred during construction.
Step 5: Compare the Before-and-After Condition
The original and post-construction reports provide a clear record for both parties. If disputes arise, the documented evidence helps resolve issues faster and with less uncertainty.
Not every project requires a follow-up inspection. However, where there is a higher risk of impact, the second inspection adds another layer of protection for property owners and builders alike.
Dilapidation Report vs Other Property Inspections
A few inspections sound alike. Here is how a dilapidation report compares to the others you might encounter.

The pattern is clear. Most inspections hunt for faults to inform a decision. A dilapidation report documents the current state so it can be used to defend everyone later.
Cost, Timing and Who Pays
Cost depends on a few things. Property size, location, and scope all matter. Speed matters too. As a rough guide, residential properties in Melbourne tend to run around $600 to $1,500. Larger or commercial properties cost more. A small unit might take 90 minutes to inspect. A large two-storey home can take half a day.
It helps to weigh that against the alternative. If damage happens and you cannot prove the prior condition, repair bills climb fast. Crack repair runs into the thousands. Structural fixes like underpinning can reach tens of thousands. A report is a small cost for that much certainty.
Who pays? Usually, the party running the construction project pays. That is often the builder or developer, especially when a council requires the report. Any property owner can also order their own report for peace of mind.
How long does it take? The on-site visit takes one to a few hours. The written report often follows within 24 to 48 hours.
How long is it valid? There is no fixed expiry. A property’s condition changes over time. Book a fresh report for each new project.
Should you tell your neighbours? If the report needs access to a neighbouring property, then yes. Arrange access first. If it covers only your own private property, a courtesy heads-up still helps.
Who Can Carry Out a Dilapidation Report?
People get this part wrong, so it is worth being firm. A qualified, independent and insured inspector should do the work. The builder working next door should never inspect your property. The conflict of interest is obvious. A report from an interested party carries little weight in a dispute.
When you choose someone, look for real experience in condition reporting. Check that they include clear photographic evidence and hold proper insurance. Independence is the whole point. It is what makes the document objective and reliable.
Protect Your Property Before the Works Begin
A dilapidation report will not stop a crack from forming. It will prove whether the project next door caused it. For homeowners across Geelong, Melbourne and regional Victoria, that clarity is worth a lot.

FAQs about Dilapidation Reports
Yes, a dilapidation report is the same as a condition report, property condition report, or dilapidation survey. All these terms refer to an independent, detailed inspection that documents the property’s current condition before nearby construction begins. This record helps identify any new damage later.
While a dilapidation report is not a contract, it is an independent and dated document that carries significant weight in disputes or claims. It provides reliable evidence of the property’s condition before construction, making it a valuable legal tool for resolving damage claims fairly and objectively.
Generally, a dilapidation report is not necessary for small renovations. These reports are most important when excavation, demolition, or construction work occurs near shared boundaries or involves heavy machinery and vibration. For minor projects away from neighbours, the risk of damage is usually low.
If damage is suspected after construction, a post-construction inspection compares the property’s current condition against the original dilapidation report baseline. Any new damage identified can then support claims for repairs or compensation, providing clear evidence of changes caused by the construction activities.
In Victoria, many local councils require a dilapidation report as part of development approval for larger construction projects. This condition helps protect neighbouring properties by documenting their condition before work begins, ensuring accountability and reducing disputes related to construction damage.
Both the property owner and the builder or developer receive a copy of the dilapidation report. Having the same detailed record ensures transparency and allows both parties to reference the property’s condition if disputes or damage claims arise during or after construction.
