You buy an apartment in a five-year-old building that looks fine during inspection. Six months after settlement, the owners corporation receives an engineer’s report identifying serious waterproofing failures, structural cracks, and non-compliant fire safety systems. Repair costs are estimated at $3 million. Who pays?

The answer involves builder warranties, owners corporation insurance, individual owner contributions, and potentially years of litigation. Understanding this before buying into strata schemes helps assess risks and avoid financial disaster.

Common property defects are the owners corporation’s responsibility to repair. This includes external walls, roofs, fire systems, structural elements, and building envelope. If these have defects, the owners corporation must fix them, funding repairs through special levies on all owners.

Your share of special levies typically matches your unit entitlement—roughly proportional to your apartment’s size and value. If total repairs cost $3 million and you own a unit with 2% entitlement in a 100-unit building, your levy is about $60,000.

This can exceed the value of your apartment if defects are severe enough. Small apartments in badly defective buildings might face special levies larger than the apartment’s market value. You can’t refuse to pay and walk away—you’re legally obligated for the levy.

Builder warranties provide a first line of defense. In NSW, builders must provide six-year statutory warranty insurance covering major defects and 2-year warranty for minor defects. Other states have similar but varying requirements.

If defects appear within warranty periods, the owners corporation claims against the builder. If the builder repairs defects satisfactorily, owners pay nothing beyond normal strata fees. This is the ideal scenario.

Reality is messier. Builders dispute whether issues are defects or normal aging. They argue defects were caused by poor maintenance, not construction failures. They claim issues fall outside warranty scope. These disputes drag on while buildings deteriorate.

Builders going into liquidation defeats warranty claims. The warranty insurance is meant to cover this scenario, but insurers also dispute claims. They argue defects aren’t covered, weren’t properly documented, or fall outside policy terms.

Warranty claims take years to resolve. Meanwhile, water ingress continues, structural issues worsen, and owners corporation must decide whether to fund temporary repairs or wait for warranty resolution. Temporary repairs might cost hundreds of thousands while waiting for warranty claims to process.

Professional negligence claims against builders, architects, engineers, or certifiers provide another potential recovery path. If professionals were negligent in design or certification, they might be liable for resulting defects.

These claims require proving negligence, which means expert reports, legal proceedings, and years of litigation. Success isn’t guaranteed. Professional indemnity insurance covers some claims, but policies have limits and exclusions.

Litigation costs can exceed recovery. Spending $500,000 in legal fees to potentially recover $2 million sounds worthwhile, but if you lose, you’ve spent $500,000 and still face the full repair bill. Owners corporations must weigh litigation risk against certain special levy costs.

Class actions by multiple buildings against the same builder or developer can share litigation costs and increase pressure for settlements. Several major Australian developments have pursued this approach with mixed results.

Developer warranties for common property sometimes extend beyond builder warranties. If the developer still exists and has assets, they might be liable for defects. Many developers structure projects through special-purpose entities that are wound up after completion, eliminating recovery prospects.

Owners corporation insurance covers some risks but typically excludes defects. Insurance pays for sudden damage from insured events—storms, fires, burst pipes. It doesn’t cover gradual deterioration or construction defects. Don’t expect insurance to cover building defect repairs.

The exception is if defects cause insured damage. For example, waterproofing defects might not be covered, but if those defects cause a flood that damages interiors, the flood damage might be covered even if repairing the underlying waterproofing isn’t.

Individual unit defects within your apartment are your responsibility and cost. If your bathroom waterproofing fails, that’s your problem and expense unless it affects common property or other units.

If your unit defect causes damage to common property or other units, you might be liable for that damage. Your apartment’s leak that damages the unit below becomes your liability. Individual unit owners should maintain appropriate insurance for this risk.

Defects in brand new buildings often emerge during the first few years. This is called the defect liability period. Smart buyers look for buildings that are 3-5 years old where major defects would have already appeared and been addressed, but buildings are still relatively new.

Buying into brand new developments means unknown defect risk. Buying into 10-year-old buildings means defects that would appear have appeared, but buildings are older. The 3-5 year sweet spot balances these factors, though it’s not a perfect solution.

Due diligence before purchase should include reviewing owners corporation records for defect reports, special levy history, and current disputes. Strata managers must provide these records to potential buyers. Reading them reveals red flags.

Buildings with ongoing special levies for defect repairs are obvious concerns. But also watch for recent engineering reports identifying issues not yet addressed, warranty claims in process, or litigation underway. These indicate potential future levies.

Sunset clauses in new apartment contracts protect buyers if completion is delayed. But they don’t protect against defects discovered after settlement. Once you settle, you own the apartment and its share of building defects.

Building inspections by qualified building inspectors can identify some defects before purchase. But inspectors can’t see inside walls or access restricted areas. Their reports help but don’t eliminate defect risk.

Some defects aren’t identifiable without destructive investigation. Waterproofing behind tiles, structural steel embedment, or internal drainage might look fine superficially but fail catastrophically. Pre-purchase inspections have limits.

Government regulations have tightened in response to defect crises, but enforcement varies. The Opal Tower and Mascot Towers incidents in Sydney led to regulatory reforms. Whether these prevent future defects remains to be seen.

Stricter licensing requirements for builders, mandatory inspections at critical stages, stronger warranty insurance, and better dispute resolution mechanisms all aim to reduce defect prevalence and improve owner protections. The impact will emerge over coming years.

Existing buildings with defects don’t benefit from regulatory improvements. Owners are stuck with buildings built under previous, weaker regimes. Recovery options are limited to warranties, insurance, and litigation under the rules that applied when buildings were constructed.

Financial planning for strata living should include reserves for potential special levies. Owning strata property creates exposure to potentially large, unpredictable costs beyond normal strata fees. Maintaining liquid savings for this possibility prevents forced asset sales if special levies arrive.

Some owners corporations build large sinking funds specifically for defect remediation. Higher than normal strata fees that fund substantial reserves provide cushion against special levies. Buildings with large sinking funds can fund at least some repairs without special levies.

Selling before defects are remediated is difficult. Once defect issues are public, selling becomes harder and prices drop. But waiting until after remediation means paying special levies before selling. Timing is challenging and there’s no perfect answer.

Disclosure requirements mean you must tell potential buyers about known defects and ongoing disputes. Hiding these issues creates legal liability. The market adjusts prices to reflect defect risks, reducing sale proceeds.

High-rise buildings face greater defect risks than low-rise buildings. Complex construction, extensive common property, and higher costs of access for repairs all increase exposure. The magnitude of potential special levies scales with building complexity.

Boutique buildings with fewer units spread defect costs across fewer owners. A $2 million defect in a 20-unit building means $100,000 per owner. The same defect in a 200-unit building means $10,000 per owner. Smaller buildings create larger individual exposure.

Understanding these risks doesn’t mean avoiding strata properties entirely. But it means incorporating defect risk into purchase decisions, maintaining financial buffers, and reading strata documentation carefully before committing.

The legal framework protects owners somewhat through warranties, insurance requirements, and liability rules. But these protections have gaps. Builders liquidating, warranty insurers disputing claims, and litigation costs all create scenarios where owners bear costs despite theoretical protections.

Buying into well-established buildings with good maintenance records, adequate sinking funds, and no major defect history reduces but doesn’t eliminate risk. Buying into brand new or very cheap developments increases risk substantially.

The reality is that strata ownership creates collective financial obligations beyond individual apartment ownership. Defects affecting common property become your financial problem through special levies. Planning for this possibility and understanding the mechanisms of responsibility, recovery, and cost allocation prevents shock when defects emerge.
