If you live in a newer strata building in NSW, chances are you’ve heard the word “defects” mentioned at some point. Cracking walls, waterproofing failures, leaking balconies, faulty fire systems — building defects can be stressful, costly and complex.
Understanding your rights — particularly around statutory warranty claims — is critical for protecting your building and your investment.
Here’s what every strata owner and committee member should know.

What is a building defect in strata?
A defect is generally defined as a fault, flaw or failure in building work that does not comply with:
The building contract
The National Construction Code
Australian Standards
Or acceptable workmanship standards
In strata schemes, defects typically affect common property, such as:
Roofing and waterproofing
External cladding
Structural elements
Fire safety systems
Plumbing and drainage
Balconies and façades
Some defects may appear immediately after completion. Others may take years to surface.
Major vs minor defects – Why it matters
Under NSW legislation, defects are categorised as:
Major Defects
These are serious issues that:
Affect structural integrity
Make the building unsafe or uninhabitable
Prevent use of part of the building
Result from serious non-compliance with the Building Code
Examples: Structural cracking, major waterproofing failure, serious fire safety defects.
Other (Minor) Defects
These include issues that do not meet the threshold of “major,” such as:
Poor finishes
Minor water ingress
Cosmetic cracking
The distinction is important because it affects the warranty period.
Statutory warranty periods in NSW
Under the Home Building Act 1989 (NSW), builders provide automatic statutory warranties for residential building work:
6 years for major defects
2 years for all other defects
The warranty period starts from the date of completion.
If a defect becomes apparent in the last 6 months of the warranty period, owners may have an additional 6 months to lodge a claim.
For strata schemes, the owners corporation is responsible for pursuing claims relating to common property.
Who is responsible for making a claim?
In strata buildings:
The Owners Corporation handles defects affecting common property.
Individual lot owners handle defects within their own lot (unless caused by common property).
The strata committee should act quickly once defects are identified. Delays can jeopardise legal rights if warranty periods expire.
What should you do if defects are suspected?
1. Engage a qualified building consultant
An independent expert can:
Conduct a defect inspection
Prepare a detailed defect report
Classify defects as major or minor
Provide recommendations for rectification
This report becomes critical evidence if legal action is required.
2. Review warranty timeframes
Confirm:
Date of practical completion
Whether the defect falls within 2 or 6 years
Whether you are nearing a limitation period
Time is everything in defect claims.
3. Notify the builder in writing
The Owners Corporation should formally notify the builder/developer:
Identify defects clearly
Attach the expert report
Request rectification within a reasonable timeframe
Keep all correspondence documented.
4. Attempt resolution
In many cases, defects are resolved through negotiation. However, if the builder does not cooperate, the Owners Corporation may need to escalate the matter.
Options may include:
NSW Fair Trading complaint
Mediation
NCAT proceedings
Legal action
Why early action is critical
Many strata schemes delay acting because:
The building “still seems fine”
There are cost concerns around engaging experts
Committees are unsure of the process
However, once warranty periods expire, recovery options become far more limited and expensive.
Proactive inspections — especially before the 2-year and 6-year marks — are strongly recommended.
Practical tips for strata committees
✔ Keep records of all building issues reported
✔ Schedule defect inspections before warranty expiry
✔ Maintain a defects register
✔ Seek legal advice early if major issues are identified
✔ Ensure your strata manager is experienced in defect management
