If you’ve recently received a notice in your letterbox advising that construction is starting next door, or that a major project is happening on an adjacent property, you’ve probably started wondering what that means for your place. Vibration from excavators. Heavy vehicles running past your boundary fence every morning. Ground movement from deep footings going in nearby. It’s a legitimate concern, and it’s one that more and more Queensland property owners are having to deal with as infill development and subdivision activity picks up across Brisbane, the Sunshine Coast, Gympie and surrounding areas.
A dilapidation inspection is one of the most practical things you can do to protect yourself in this situation. Most people haven’t heard of them until the notice arrives, but for anyone with a property near an active construction project, they can make a significant difference when it comes to claims, disputes and peace of mind.
What Actually Is a Dilapidation Inspection?
A dilapidation inspection is a detailed, documented record of the current condition of your property, carried out before nearby construction or development work begins. The inspector goes through the property thoroughly, photographing and recording every existing crack, defect, movement, or area of concern — inside and out, from the roof through to the subfloor.
The result is a time-stamped condition report that creates a clear baseline: this is what the property looked like before the work next door started. That document becomes your evidence if anything changes during or after construction. Without it, any claim you make about damage caused by nearby works is your word against the developer’s or builder’s. With it, you have a factual before-and-after comparison that holds up.
It’s worth noting that dilapidation reports aren’t only used by neighbouring property owners. The party undertaking the construction — the developer, builder, or local council — will often commission their own dilapidation reports on surrounding properties as a standard part of their risk management before a project kicks off. This protects them as much as it protects you. But that report belongs to them, not you. Having your own independent report ensures the documentation reflects your interests and your observations, not theirs.
What Gets Recorded in the Report?
A thorough dilapidation report goes well beyond a quick walk-around with a camera. An experienced inspector will work through every accessible area of the property and document:
- Existing cracks in walls, ceilings, cornices, render and brickwork, with measurements and photos
- The condition of the roof exterior, gutters, flashings and fascias
- Subfloor condition, including stumps, bearers and any existing movement or settlement
- Windows and door frames — whether they open and close correctly, any racking or distortion
- Driveway, pathways and external paving
- Retaining walls and fences along the boundary
- Any drainage infrastructure visible on the property
Everything is photographed and described clearly. Good reports don’t just note that a crack exists — they describe its orientation, approximate width, location within the structure, and whether it shows signs of being active or long-standing. That level of detail is what separates a useful report from a generic one that won’t hold up if you ever need to use it.
When Should You Get One?
The single most important rule with dilapidation inspections is timing. The report needs to be completed before construction begins. Once equipment moves onto a site and work gets underway, the window to establish a clean baseline closes. Any new damage that appears after work starts becomes impossible to prove conclusively, because there’s no documented starting point to compare against.
Practically speaking, if you receive a development notice, a construction commencement notice, or even just hear through the neighbourhood that something’s happening next door, that’s your trigger. Don’t wait to see if the work causes a problem — by then it’s too late for a dilapidation report to do you any good.
The types of projects that most commonly warrant a dilapidation inspection for neighbouring owners include:
- Demolition and rebuild on an adjacent block
- Dual occupancy or townhouse developments on nearby land
- Commercial or industrial builds close to a residential property
- Significant excavation or earthworks, including for basement car parks or swimming pools
- Road or infrastructure upgrades running adjacent to your boundary
- Subdivision works that involve heavy machinery operating close to your fence line
Properties on smaller blocks, older homes with existing minor cracking, and any building with a subfloor (particularly those on stumps) tend to be more vulnerable to movement caused by nearby works. But all property types can be affected, especially where deep excavation is involved or where significant vibration comes from compaction equipment and heavy vehicles.
Why an Independent Inspector Matters Here
As mentioned earlier, it’s fairly common practice for a developer or builder to organise dilapidation inspections on surrounding properties before work starts. This is increasingly a requirement under local council approvals and development conditions. However, those reports are commissioned by the developer, conducted by an inspector they’ve engaged, and prepared in a format that suits their documentation process.
That doesn’t mean those reports are dishonest. But it does mean they’re not yours, you don’t control them, and they may not capture everything relevant to your property from your perspective. An independent dilapidation inspection gives you a document you own and can use however you need to — whether that’s to support a claim, to open a conversation with a developer’s insurer, or simply to have on file as protection.
Independence also matters because the inspector isn’t working for either party in any potential dispute. Their job is to record what they see, clearly and factually. That objectivity is worth a lot if a situation ever escalates.
What Happens After the Report?
Once construction has finished, or at a point where you believe damage may have occurred, a post-construction dilapidation inspection can be carried out using the same methodology and the same property. The two reports are then compared side by side. Any new cracking, movement, settlement or damage that wasn’t present before the works began becomes clearly identifiable.
This comparison is what gives a dilapidation report its real value. It moves the conversation from opinion to evidence. Instead of arguing about whether a crack was already there, both parties have documented photographic and written records to refer to. That often resolves disputes far more quickly than they would otherwise, and in some cases prevents them from escalating at all.
It’s also worth keeping in mind that dilapidation reports can be used proactively. If you’re the one planning construction on your own land, commissioning dilapidation reports on neighbouring properties before you start is a way of protecting yourself from claims that may not be valid. Getting the pre-construction condition documented means you’re not liable for damage that was already there.
Common Questions We Hear
Does the developer have to let me in to inspect?
The dilapidation inspection is conducted on your own property, so access isn’t dependent on the developer’s permission. Your inspector needs access to your home, including the subfloor and roof space where relevant. The neighbouring site itself isn’t inspected.
What if construction has already started?
If work has already begun, a dilapidation inspection can still be useful — it just establishes the condition from that point forward rather than from before works commenced. It may not give you the same level of protection for damage that occurred in the earliest stages, but it’s still better than having no documentation at all for the remainder of the project.
How is this different from a standard building inspection?
A standard building inspection is typically carried out for buyers or owners to understand the structural condition of a property they’re purchasing or maintaining. A dilapidation inspection has a specific and different purpose: it’s a condition record designed to be used as evidence in relation to nearby construction activity. The methodology, focus areas, and way the report is structured are all geared around that purpose.
The Bigger Picture
Development is part of how communities grow, and most construction projects finish without causing any real issues for neighbouring properties. But the ones that do cause problems can be expensive, stressful, and legally complicated to resolve without the right documentation in place.
A dilapidation inspection doesn’t cost a great deal relative to what it protects. It takes a few hours, produces a thorough photographic and written record, and sits in a file that you’ll hopefully never need to open again. If you do need it, you’ll be extremely glad it’s there.
