Building Defects (Strata) Explained for Property Buyers
Building defects in strata are faults in how an apartment or townhouse complex was designed or built, such as water leaks, cracking or fire safety problems. Because most of them sit in shared parts of the building, every owner ends up paying a share of the repair.
What Does Building Defects (Strata) Mean?
A building defect is something that was designed or built incorrectly, or that has failed earlier than it reasonably should have. In a strata building the usual culprits are waterproofing in bathrooms, balconies and roofs, cracking in concrete or render, faulty fire safety systems, and problems with cladding or drainage. Ordinary wear and tear is different. A defect is a fault in the original work, not a building simply getting older.
Buyers rarely see defects during an open home. They tend to surface in the paperwork: meeting minutes that mention leaks or engineering reports, a levy raised to fund repairs, correspondence with a builder or developer, or a legal claim the owners corporation is running. In newer buildings you may also see references to a defects bond and independent inspection reports.
The catch is that buying a lot in a strata scheme means buying a share of the whole building's problems. Even if the unit you inspect is dry and tidy, you will contribute to fixing a failed membrane on the roof or a basement that takes in water. A defect is not automatically a reason to walk away, but it changes what the property is worth and how much cash you need in reserve.
Why This Matters for Buyers
Defects turn a known purchase price into an open-ended one. Levies you can see in the budget are easy to plan for. A remediation bill that has not been costed yet is not, and large rectification programs can run for years and be funded through repeated special levies. The question to answer before you commit is not simply whether defects exist, but how far along the building is in identifying, costing and paying for them.
Who pays is the second issue. In NSW, residential building work generally carries statutory warranties, commonly described as six years for major defects and two years for other defects. If a building is still inside those periods and the builder or developer is solvent, the owners corporation may be able to have the work fixed at someone else's cost. Once the periods have passed, or the builder has gone out of business, the cost usually falls back on the owners. Where a particular building sits on that timeline is something your solicitor or conveyancer should confirm, because the detail matters.
Defects also affect finance and resale. Some lenders are cautious about buildings with significant unresolved defects or active litigation, and valuations can come in lower. That can limit your borrowing now and narrow your pool of buyers later. On the other hand, a building that has already found its problems, fixed them properly and documented the work can be a sounder purchase than a newer one whose issues have not appeared yet.
Finally, defects give you leverage if you understand them. A seller in a building with a pending special levy or a known waterproofing program has fewer competing buyers. A clear picture of the likely cost per lot lets you price that in rather than guessing.
Common Mistakes Buyers Make
Most trouble comes from assuming a clean-looking unit means a sound building, or from reading the strata records too quickly.
- Judging the building by the unit — fresh paint and new flooring inside a lot say nothing about the roof, basement, facade or fire systems, which is where the expensive faults sit.
- Assuming new means defect-free — many defects only show up a few years after completion, once the building has been through a few wet seasons. A near-new block can carry more uncertainty than an older one with a long repair history.
- Skimming the minutes — references to an engineer's report, a defects committee, a tribunal or court matter, or repeated complaints about leaks in different units are signals to dig into, not background noise.
- Ignoring the funding gap — knowing there is a defect is only half the picture. Check whether repairs have been quoted, whether a levy has been raised, and whether the capital works fund could realistically cover it.
- Relying on warranties without checking them — warranty periods, insurance cover and bond arrangements depend on the building's age, height and the status of the builder. Do not assume someone else will pay until that has been confirmed.
How This Shows Up in the Illawarra
The Illawarra has added a large number of apartments over the past decade or so, particularly in the Wollongong city centre, around North Wollongong and Fairy Meadow, and in newer precincts in Shellharbour. A good share of local unit stock is therefore young enough for defects to still be emerging, and some buildings are part-way through claims or rectification work. That makes the strata report a core part of buying a unit here, not a formality.
Coastal conditions add to it. Salt air, wind-driven rain and strong sun are hard on balconies, balustrades, window seals, exposed steel and render. Buildings close to the water in suburbs such as Wollongong, North Wollongong, Thirroul and Shellharbour can show corrosion and water entry earlier than similar buildings inland. Older walk-up blocks from the 1960s and 1970s have their own pattern, typically concrete deterioration, ageing balconies and tired roofing, which is closer to deferred maintenance than original defects but lands on owners in the same way.
Because most Illawarra units sell by private treaty, buyers usually have time to do this homework before exchange. Use it. Order the strata report early, read the minutes for the past several years, and ask the agent directly whether any defect reports, claims or special levies are in progress. Where a building has a known issue, the price gap between it and a comparable block nearby is often where the real negotiation sits.
Practical Takeaway
Treat defects as a question of cost, timing and responsibility. Find out what is wrong, what it is expected to cost, who is paying, and how much of the work is already done. A building with a costed, funded and well-managed repair program is a very different proposition from one where owners are still arguing about whether there is a problem.
Get a thorough strata report from an inspector who reads the minutes and correspondence, not just the financial statements. Ask your solicitor or conveyancer about warranty periods, any insurance or bond in place, and any legal action involving the owners corporation. If the report mentions technical issues you cannot assess, a building inspector or engineer can give you a view on severity.
In plain terms: when defects come up, do not panic and do not wave them through. Put a realistic dollar figure and timeframe on your share, check that your lender is comfortable with the building, and adjust your offer to match. If the numbers cannot be pinned down and the seller will not reflect that uncertainty in the price, it is reasonable to move on to another property.
Frequently Asked Questions
What counts as a building defect in a strata property?
A fault in the design, materials or workmanship of the building, such as failed waterproofing, structural cracking, non-compliant fire safety measures or defective cladding. It is different from normal ageing or lack of upkeep, although the two can overlap in older buildings.
When do defects usually come up in a purchase?
Most often when the strata report comes back. The inspector reviews the owners corporation's minutes, financials and correspondence, and this is where leaks, expert reports, claims and repair levies are recorded. They can also come up in the contract documents or in conversation with the agent.
Is it risky to buy into a building with defects?
It can be, depending on how serious the defects are and how well they are being handled. The higher risk is a building with significant problems that have not been costed or funded. A building with a clear repair plan and money set aside is far more predictable.
Can I negotiate the price because of defects?
Yes. Known defects, pending special levies and unresolved claims are all legitimate grounds for a lower offer. Sometimes the contract can also deal with who pays a levy that has been raised but not yet due, which your solicitor or conveyancer can advise on.
Should first home buyers be concerned about strata defects?
Yes, particularly because units are a common first purchase and first home buyers often have limited savings left after settlement. An unexpected special levy in the first year or two can put real pressure on a tight budget, so it is worth checking carefully before you commit.
How do defects affect the timing of my purchase?
They can slow things down. You may need extra time to obtain reports, get advice on technical findings, or satisfy your lender about the building. It is better to do this before exchange, or within the cooling-off period, than to discover the detail once you are locked in.
How are strata defects handled under the NSW buying process?
NSW has statutory warranties for residential building work, and there is a defects bond and inspection scheme that applies to many newer strata buildings. Which protections apply to a specific building depends on its age, size and circumstances, so treat this as general information and confirm the position with your legal representative.
Can a buyers agent help with building defects?
A buyers agent can arrange the right reports early, flag warning signs in the strata records, compare the building against others nearby, and factor the likely cost into the negotiation. Legal questions about warranties and claims still belong with your solicitor or conveyancer.
