Understanding What Your Strata Corporation Needs to Document

Differentiating Between Major & Minor Strata Defects

building defect is a fault in a building’s design, construction, or maintenance.

Under NSW law, strata corporations must distinguish between minor and major defects, as this affects their management:

  • Minor defects are typically cosmetic, such as cracked tiles.
  • Major defects are serious problems that can impact the safety and stability of the building.

According to research from the NSW Building Commission, the most common major defects in strata properties are:

  • Waterproofing failures
  • Fire safety deficiencies
  • Structural elements issues

These significant issues can compromise the building’s integrity and pose risks to residents if not addressed promptly.

Examples of major defects include:

  • A serious fault in a key building element, such as the foundation, footings, or a load-bearing wall.
  • Defective waterproofing that leads to significant water penetration into the building.
  • fire safety system that was improperly designed or installed, failing to meet compliance standards.
  • Any defect that makes a part of the building uninhabitable or likely to collapse.

Key Legal Protections & Timelines for Strata Defects in NSW

In NSW, owners corporations are protected by statutory warranties under the Home Building Act 1989 (NSW). These warranties are automatically included in contracts for residential building work and ensure that construction is performed with due care and skill.

The warranty periods are critical, lasting:

  • Six years for major defects
  • Two years for all other defects

These periods start from the date the work was completed.

Further protection is provided by the Design and Building Practitioners Act 2020 (NSW), which establishes a statutory duty of care for all parties involved in construction. This duty requires builders, designers, and project managers to avoid causing economic loss due to defects.

Owners have:

  • Six years from when a defect first becomes apparent to file a claim
  • This duty applies retroactively to defects identified after 2014, subject to a 10-year long-stop limitation period

How to Systematically Identify Strata Building Defects

Conducting Regular Visual Inspections of Common Property

The first step for an Owners Corporation in identifying potential building defects is to conduct regular visual inspections of common property. These routine checks should focus on key building elements such as:

  • the roof
  • fire safety systems
  • structural components

During these inspections, it is important to look for clear warning signs. For instance, suppose that during an inspection, you observe cracks in the building’s façade; this could indicate a more serious structural issue requiring further investigation. All initial findings should be carefully documented with detailed descriptions and supporting photographs to create a clear record for any subsequent actions.

When to Engage Professionals for an Expert Strata Defect Report

While visual inspections are a valuable starting point, they may not uncover hidden or complex issues within a strata building.

It is crucial to engage qualified building inspectors or engineers for a thorough defect assessment, as they possess the expertise to identify a wider range of problems. These professionals can be consulted after defects are noticed or proactively before a statutory warranty period expires.

Professionals provide detailed reports that outline the nature, severity and location of defects, along with recommendations for rectification.

Imagine a scenario where water damage is noticed in a common area. In that case, a professional inspector could identify faulty waterproofing from the original construction as the root cause— a major defect covered under statutory warranties.

The process for a professional assessment typically involves:

  • Desktop Research: The expert begins by gathering and reviewing as-built records to understand the building’s construction.
  • Initial Inspection: A general, often visual, inspection gathers information not found in documents and identifies areas needing further investigation.
  • Further Investigation: When necessary, more intrusive inspections—such as checking ceiling spaces or drilling into walls—confirm the cause and extent of a defect.

A Step-by-Step Guide to Documenting Strata Defects

Creating & Managing a Comprehensive Strata Defects Register

A defects register is an essential tool for an Owners Corporation to systematically document building defects found in common property. This register helps track all identified issues, manage the rectification process, and provides crucial evidence for any potential warranty claims or legal proceedings.

To ensure the register is effective, it should capture specific details for each entry. For example, if water damage appears in a common hallway, the register should log:

  • Date of discovery: When the defect was first noticed.
  • Location: A precise description, such as “ceiling of the third-floor lobby.”
  • Detailed description: Notes on the nature of the damage, like “visible water stains and peeling paint.”
  • Status: The current stage of the issue, such as “reported to strata manager,” “quote received,” or “repairs completed.”
  • Actions taken: A log of all steps, including communications, inspections, and repairs.

The register must be a living document, regularly updated by the strata manager or a designated committee member. It is also important for the Owners Corporation to maintain its own independent control over this list to ensure defects are not marked as complete by a builder without proper verification.

Taking Effective Photographic & Video Evidence

Visual evidence is fundamental to substantiating any building defect claim, as it provides a clear and indisputable record of the problem’s nature and severity. High-quality photographs and videos can significantly strengthen the Owners Corporation’s position when communicating with builders or pursuing a formal claim.

When capturing visual evidence, it is important to be thorough. For example, if cracks are found on a building’s exterior wall, you should:

  • Take close-up photos to show their length and width.
  • Capture wider shots to provide context for their location.
  • Use multiple angles and ensure good lighting to accurately capture the issue.

For dynamic problems like water leaks, a video is more effective as it can show the flow of water and the full extent of the affected area.

Every photograph and video file must be meticulously labelled with the date, time, and precise location. This organisational step is critical for creating a credible and easily searchable record of evidence for your strata building.

Maintaining Essential Strata Records & As-Built Documents

Beyond the defects register and visual evidence, it is crucial for the Owners Corporation to maintain a complete portfolio of all building documents. These records provide essential context and are often required for legal or warranty purposes. Under the Strata Schemes Management Act 2015 (NSW), many of these documents must be provided by the original owner at the first Annual General Meeting.

Key records that every strata scheme should securely store include:

  • All plans, specifications, and “as built” drawings
  • Occupation certificates and other compliance certificates
  • Fire safety certificates and schedules
  • Warranties for any building work, plant, or equipment
  • The initial maintenance schedule

These documents are integral to the ongoing operation and maintenance of the strata scheme. It is recommended to keep these records in a digital format that is properly indexed for easy access.

Maintaining organised records not only helps in managing defects but also provides a clear audit trail in case of any disputes. Critically, the Strata Schemes Management Act 2015 (NSW) requires that these records be retained for at least seven years.

Ensuring Your Strata Documentation is Legally Sound

Fulfilling Documentation Needs for Strata Warranty Claims

When making a warranty claim for strata building defects in NSW, your documentation must clearly show that the issue is covered by the statutory warranties in the Home Building Act 1989 (NSW).

Furthermore, meticulous records are essential for substantiating your claim and demonstrating non-compliance with building standards.

For example, if a roof leak occurs in a residential apartment building, a strong warranty claim would be supported by a comprehensive evidence file. This file should include:

  • Original building contract: establishes the agreement and the parties involved.
  • Detailed defect information: precise location, nature, and extent of the leak.
  • Visual evidence: high-quality photographs and videos of the defective roof.
  • Communication records: log of all correspondence with the builder regarding the defect.

A defects report from a qualified building inspector is also a critical component. The report must clearly define the defect’s nature, its cause—such as faulty workmanship or defective materials—and the necessary rectification work.

To strengthen the claim, the report should reference relevant sections of the National Construction Code and the Home Building Act 1989 (NSW) to prove non-compliance.

Preparing Expert Reports for Legal & Tribunal Proceedings

In legal proceedings, such as a strata dispute in NCAT, building defect reports from qualified experts like engineers or building consultants serve as a vital piece of evidence. These reports offer an independent and objective assessment of the defects, their causes, and the estimated costs for rectification.

Consider a case where a strata owners corporation takes legal action against a builder for serious defects on common property. The expert report becomes a cornerstone of the evidence presented. The report must be comprehensive, detailing:

  • Nature and extent: of all identified defects.
  • Impact on performance standards: how defects affect the building’s required performance.
  • Estimated rectification cost: all necessary repair expenses.

The expert who prepared the report may also be required to provide testimony in court or at the tribunal. This testimony helps to explain their findings, clarify technical details, and respond to any questions from the opposing party, significantly influencing the outcome of the proceedings.

How to Use Your Strata Documentation to Resolve Defects

Communicating with Builders & Developers Using Your Evidence

Once your strata corporation has thoroughly documented a building defect, the process of resolving strata building defects & disputes begins by formally notifying the responsible party—often the builder or developer.

Presenting a comprehensive evidence file strengthens your position and provides a clear basis for demanding rectification. Ensure this communication is formal and includes all relevant documentation.

Ensure your evidence file is organised and compelling, leaving little room for dispute. When demanding action, provide:

  • The defects register: A clear, chronological record of the issue.
  • Photographic and video evidence: Visuals that offer indisputable proof of the defect’s nature and severity.
  • Expert reports: Independent assessments from a building consultant or engineer to validate the claim.

It is crucial to present these defect reports to the builder before any statutory warranty periods expire. This step preserves your legal rights and places the onus on them to respond with a rectification plan.

Adopting a Risk-Based Approach to Prioritise Rectification

When a strata building has multiple defects, addressing them all at once may not be financially possible. A risk-based approach helps the Owners Corporation focus on the most critical issues first by assessing each defect’s potential consequences and likelihood of causing harm or further damage.

risk matrix can be used to categorise defects effectively. This tool evaluates issues based on:

  • Likelihood: How probable is it that the defect will cause a problem?
  • Consequence: How severe would the outcome be if the defect is not fixed?

For example, a minor cosmetic crack might be rated as low risk, while a faulty fire safety system would be rated as an extreme risk requiring immediate attention.

This method allows the strata committee to make informed decisions, allocate funds effectively, and systematically address defects—starting with those that pose the greatest threat to safety and the building’s integrity.

Conclusion

Properly documenting strata building defects requires a meticulous approach, from identifying issues and understanding legal timelines to creating a comprehensive evidence file with registers and expert reports. This systematic documentation is essential for substantiating warranty claims, communicating effectively with builders, and protecting the value of your strata property.
