What "Failing" a Building Inspection Actually Means
A building inspection is not like a school test where you get a pass or fail grade. The inspector will write down all the problems they find. Say how serious each one is.Â
So when people say a property failed a building inspection, they mean the report found problems. These are problems that cost a lot of money to fix or make a home to live in.
I have done inspections in Moonee Ponds where the buyer thought everything was perfect. The house looked nice, the carpets were clean, and the yard was well kept.Â
When I looked more closely, I found major problems like cracks in the foundation, water damage, and roof issues. These are the kinds of things that can cause trouble.
Major vs Minor Defects
Every building inspection report splits findings into categories. Minor defects include a sticking door, a cracked tile, or peeling paint on a window frame. They need attention, but they won’t keep you up at night.
Major defects are different. These are problems that affect the property’s structure, safety, or livability.Â
According to Australian Standard AS 4349.1, a major defect is one that needs significant repair and could make the building unsafe or uninhabitable if left alone. That’s the line between “worth negotiating on” and “walk away.”
Some examples of major defects we regularly flag:
- Structural cracking through brickwork or load-bearing walls
- Significant movement in footings or stumps
- Active termite damage or evidence of concealed timber pest activity
- Non-compliant plumbing or electrical work
- Roof framing defects that compromise the structure
Any one of those can change your decision about a property. And most buyers don’t find out until it’s too late, because they skipped the inspection or relied on a verbal opinion from a mate.
Why the Report Language Matters
You’ll notice a good inspection report uses specific terms.Â
“Significant” doesn’t mean the same thing as “minor.”Â
“Requires immediate attention” is not the same as “monitor over time.”Â
These words carry weight, they tell you exactly how urgently you need to act. Many old homes around Moonee Ponds and nearby areas like Ascot Vale were built in the early 1900s. Beautiful homes, but they come with era-specific issues.Â
Deteriorating subfloor timbers, outdated wiring, original plumbing that’s well past its useful life. None of that means the house is worthless. It means you need to know what you’re buying.
That’s the real point of a building inspection. It’s not about passing or failing. It’s about giving you the full picture so you can make a smart decision. Buy with confidence, negotiate on price, or walk away before you’re locked in.
If you’re looking at a property and wondering what a building inspection might uncover, our pre-purchase property inspections give you exactly that clarity before you commit.
Most people think the scary part is what the report finds. But the real risk? Not getting one at all.
The Most Common Issues That Cause Building Inspection Failures
I’ve inspected hundreds of properties across Melbourne and the surrounding areas. The same problems show up again and again. Most of them aren’t dramatic. They’re quiet issues that hide behind fresh paint and new carpet.
Here’s what fails a building inspection most often.
Structural Defects
Cracks in brickwork. Sagging rooflines. Floors that bounce when you walk across them.
These are the big ones. Structural defects tell you the bones of the house aren’t right, they can mean foundation movement or load-bearing walls that have been messed with.Â
In older Moonee Ponds homes built on reactive clay soils, I see cracked foundations more than you’d expect.
And most buyers walk right past them because they’re looking at the kitchen.
Moisture and Water Damage
Water is the enemy of every building. Full stop.
Leaking roofs, poor drainage around the base of the house, rising damp in subfloor areas. These create rot, mould, and long-term structural decay.Â
I’ve pulled back shower screens in renovated bathrooms and found waterproofing that was never done properly.
The tiles looked great. Underneath was a disaster. But you’d never know without someone checking.
Electrical and Plumbing Problems
Outdated wiring is a safety hazard. So is DIY plumbing that doesn’t meet Australian Standards.
Switchboards with old ceramic fuses, exposed wiring in roof cavities, and unlicensed plumbing work all come up regularly.Â
According to Energy Safe Victoria, faulty electrical installations remain one of the leading causes of house fires in the state.
That alone should tell you why inspectors flag these issues hard.
Roof and Gutter Defects
Broken tiles. Rusted flashing. Gutters pulling away from the fascia. Your roof cops the worst of Melbourne’s weather.Â
If it’s not maintained, water gets in. And once water gets in, everything downstream suffers.
I’ve seen ceiling stains that sellers painted over the morning before an open home. A building inspection catches what a coat of Dulux tries to hide.
Pest and Timber Damage
Termites don’t send you a warning letter. They eat through timber framing silently. Subfloor timbers, door frames, and roof trusses are common targets.
In areas like Moonee Ponds and Ascot Vale where many homes have older timber subfloors, a timber pest inspection is critical.
By the time you see visible damage, the problem has been going on for months or even years.
The Consumer Affairs Victoria building inspection guide for property buyers outlines what to look for and why getting an independent inspection before you buy is so important.
Here’s a rundown of the issues we flag most during building inspections:
- Foundation cracks and signs of ground movement
- Water ingress from failed waterproofing or poor drainage
- Non-compliant electrical work or outdated switchboards
- Roof damage including cracked tiles and corroded flashing
- Active or previous termite activity in timber structures
Most people don’t find out about these problems until it’s too late. They’ve already signed the contract. They’ve already moved in. That’s why getting a pre-purchase property inspection done before you commit is the smartest move you can make.
One thing I always tell buyers: a failed inspection isn’t necessarily a deal-breaker.
It’s information. It gives you power to negotiate, to budget for repairs, or to walk away before a small problem becomes your expensive problem. The real risk is not knowing at all.

Major Defects vs. Minor Defects, What the Difference Means for You
Not every issue found during a building inspection carries the same weight. Some problems are small cosmetic blemishes. Others could make the whole structure unsafe.
Knowing the difference saves you from panic and helps you make smart decisions.
What Counts as a Major Defect?
A major defect is anything that makes the building unsafe or unlivable. Think structural cracking through load-bearing walls. Think a roof frame that’s undersized for the span it covers. These aren’t things you can ignore or fix with a weekend DIY job.
According to the Victorian Building Authority, a major defect includes any issue that causes or is likely to cause the inability to inhabit or use the building for its intended purpose. That’s the legal line in the sand.
Here’s what I see flagged as major defects most often in Moonee Ponds:
- Cracked or bowing retaining walls that could collapse
- Active termite damage to structural timber
- Defective waterproofing in wet areas causing subfloor rot
- Non-compliant electrical work with no safety switch
- Severe foundation movement affecting wall and door frames
Any one of these can fail a building inspection outright. And most buyers don’t find out until it’s too late, usually after they’ve already fallen in love with the place.
What About Minor Defects?
Minor defects won’t make the building dangerous. They’re more about finish quality and wear. A scratched benchtop. A sticking door. Paint touch-ups missed by the builder. These things matter, they just don’t carry the same urgency.
But here’s the catch. Minor defects add up fast.
I’ve inspected properties around Ascot Vale and Essendon where the minor defect list ran to three pages. Each item was small on its own.
Together they painted a picture of rushed construction and poor quality control. That tells you something about the builder’s standards.
Minor defects typically won’t fail a building inspection on their own. They do get documented in the inspection report, and you can use them to negotiate repairs or a price adjustment before settlement.
Why the Distinction Matters to You
When you get your inspection report back, don’t just count the issues. Read the severity ratings. A report with two major defects is far more serious than one with twenty minor items.
Major defects can cost tens of thousands to fix. Some require engineering reports before any remediation work even starts. Minor defects might cost a few hundred dollars each, sometimes less.
So what should you actually do with this information? Here’s a simple framework:
- Read the summary page of your report first for any major defect flags
- Check if major defects are structural or related to safety systems
- Get a specialist quote for any major defect before making decisions
- Review the minor defect list for patterns of poor workmanship
- Use the full report to negotiate with the seller or builder
We see this mistake all the time. People fixate on a chipped tile and completely miss the moisture staining on the ceiling that points to a leaking shower upstairs. One’s cosmetic. The other could mean ripping out an entire bathroom.
If you’re buying in Moonee Ponds and you want clarity on what’s actually wrong with a property, a pre-purchase property inspection gives you the full picture before you commit. That’s where the real value sits.
Frequently Asked Questions
Do older homes in Moonee Ponds fail building inspections more often than newer ones?
Older homes in Moonee Ponds don’t automatically fail, but they do carry more era-specific risks. The key is knowing what you’re buying before you sign anything. An inspector who knows the area will know exactly where to look.
What's the difference between a major defect and a minor defect on a building inspection report?
A major defect affects the structure, safety, or livability of the home. A minor defect is something like a sticking door or a cracked tile.
Can a seller fix defects before an inspection to hide them?
Yes, and it happens more than you’d think. Fresh paint over ceiling stains, new carpet hiding damaged subfloor timbers, and recently grouted tiles covering failed waterproofing are all common attempts to mask problems.
Is moisture damage really that serious, or is it something you can just dry out and move on?
Moisture damage is serious, and drying it out is rarely the whole fix. Left alone, moisture damage gets worse every season. The real problem isn’t the water you can see.
It’s the damage that’s been building quietly for months or years before anyone noticed.
Do I need a separate pest inspection, or does a building inspection cover termites too?
A standard building inspection and a timber pest inspection are two separate reports.
A building inspector looks at structural and safety defects. A pest inspector specifically checks for termite activity, timber decay, and conditions that attract pests.Â
What electrical issues most commonly come up during building inspections in Victoria?
Old ceramic fuse switchboards, exposed wiring in roof cavities, and unlicensed DIY electrical work are the most common findings.
According to Energy Safe Victoria, faulty electrical installations are one of the leading causes of house fires in the state.
