The Apartment Guy | Insight #003
I’m sharing a series of practical insights to help apartment buyers understand what to look for, what questions to ask and how to make more informed property decisions. This is the third in the series.
Fresh paint can hide a lot. So can a beautifully renovated kitchen. When buying an apartment, some of the biggest risks are hidden behind the walls—and they’re often the ones that cost owners the most.
Walk through an apartment inspection and it’s easy to be distracted by what you can see.
The natural light.
The renovated bathroom.
The beautiful kitchen.
The outlook from the balcony.
That’s exactly what open homes are designed to showcase.
But here’s something many buyers don’t realise.
The apartment is only one part of what you’re buying.
Some of the most significant issues affecting apartment owners are hidden from view.
They’re behind walls.
Above ceilings.
Beneath waterproof membranes.
Inside fire safety systems.
And you could inspect an apartment ten times without ever seeing them.
Did you know?
According to Building Commission NSW’s 2025 research, published in April 2026, the two most common serious defects identified in NSW strata apartment buildings were:
• Waterproofing
• Fire safety systems
The same research also found that newer apartment buildings are experiencing lower rates of serious defects, suggesting recent building reforms are beginning to make a positive difference.
That should reassure buyers—not alarm them.
Because the lesson isn't that apartments are risky.
The lesson is that good due diligence matters.
The encouraging news is that the industry’s biggest risks are well understood.
Which means they’re also things you can investigate before you buy.
Waterproofing isn’t just a leaking shower
When people hear the word waterproofing, they often imagine a small leak in the bathroom.
In reality, waterproofing failures can affect balconies, rooftops, planter boxes, podium slabs, basements and external walls.
Water has an extraordinary ability to find the smallest weakness.
Left unresolved, it can lead to corrosion, concrete deterioration, mould, damaged finishes and expensive remediation works.
The challenge is that none of this is necessarily visible during an open home.
A freshly painted ceiling doesn’t tell you whether it was repaired last week because of water ingress.
A beautifully renovated apartment doesn’t tell you whether the balcony membrane failed two years ago.
That’s why presentation and building condition aren’t always the same thing.
Fire safety is about much more than smoke alarms
Fire safety is another area buyers rarely think about.
Yet it’s one of the most important building systems in any apartment complex.
— Fire doors
— Fire-rated walls
— Smoke control systems
— Emergency lighting
— Exit signage
— Fire hydrants
— Routine inspections
These systems work together to protect residents if something goes wrong. When upgrades are required, they can become significant projects for an owners corporation.
Again, it’s not something you’ll identify by walking through a beautifully presented apartment.
So what?
This isn’t about becoming suspicious of every apartment building. Far from it. It’s about recognising that a visual inspection only tells part of the story.
An apartment can look immaculate while the building has significant maintenance challenges.
Equally, an older building may look less glamorous but have an outstanding maintenance history, a proactive owners corporation and strong financial planning.
Buying with confidence isn’t about finding perfection.
It’s about understanding what you’re buying into.
Here’s where experience matters...
When I’m assessing an apartment, I’m not looking for reasons to walk away.
I’m looking for reasons to understand more.
If waterproofing has been mentioned, I want to know:
What caused the issue?
Was it professionally investigated?
Was it properly rectified?
Has it returned?
If fire safety works have been recommended, I want to understand:
Have they been completed?
Are they budgeted for?
Are they still outstanding?
Is the owner’s corporation proactively managing the building?
The answers to those questions tell me far more than a cosmetic renovation ever could.
Good due diligence looks beyond the obvious
One of the biggest mistakes buyers make is assuming that if they can’t see a problem, it probably doesn’t exist.
That’s simply not how apartment buildings work.
Many of the most significant issues are hidden inside the building itself.
The good news?
Those issues often leave a trail…
Engineering reports
Maintenance records
Strata minutes
Capital works planning
Expert advice
Good due diligence is about bringing those pieces together before you commit—not after.
Buy with confidence
Buying an apartment should be exciting. It shouldn’t feel uncertain.
The goal isn’t to avoid every building that has ever experienced an issue.
It’s to understand what questions to ask before making one of the biggest financial decisions of your life.
Because when you understand what’s happening behind the walls—not just what’s in front of them—you make better decisions. And better decisions lead to greater confidence.

Research
Source: Building Commission NSW, Research on Serious Building Defects in NSW Strata Communities (2025 Research), published April 2026. The research found that 53% of surveyed NSW strata apartment buildings had at least one serious defect, with waterproofing (22%) and fire safety systems (17%) identified as the two most common categories. It also found that newer apartment buildings are showing lower rates of serious defects, suggesting recent building reforms are improving outcomes.
