Building Defects Claims — Brisbane Construction Lawyers

Building defects are one of the most common sources of construction disputes in Queensland. Whether you are a building owner dealing with cracking foundations, a developer managing non-compliant work, or a contractor defending an allegation of defective construction, the legal framework for building defects claims is complex and time-sensitive. Boss Lawyers acts for building owners, developers, contractors, and subcontractors in defects claims across Queensland.

What Is a Building Defect?

A building defect is work that does not comply with the contract, the building code, approved plans, or applicable Australian Standards. Defects are generally categorised as:

• Patent defects: Visible defects discoverable by a reasonable inspection at the time of practical completion or handover — for example, cracked tiles, uneven flooring, gaps in cladding
• Latent defects: Defects not discoverable by reasonable inspection at handover, which only become apparent later — for example, structural movement, water ingress behind walls, substandard foundations, waterproofing failures

The distinction matters for limitation periods and for your rights under defects liability clauses in standard building contracts.

Limitation Periods — Act Before It’s Too Late

Building defects claims are subject to strict limitation periods in Queensland:

• Contract claims: 6 years from the date of breach (typically practical completion) under s 10 of the Limitation of Actions Act 1974 (Qld)
• Latent defects: An extended period may apply — time runs from the date the defect was or could reasonably have been discovered, but the longstop period in Queensland is 12 years from practical completion
• QBCC complaint (residential work): Complaints to the QBCC must generally be made within 6 years of practical completion (or 3 years for some categories)
• Negligence claims: 3 years from the date of discoverability, subject to a 12-year longstop

Waiting too long to act is one of the most common mistakes in building defects disputes. If you suspect a defect, get advice immediately.

Who Can You Sue?

Depending on your position in the construction chain and the nature of the defect, your claim may lie against:

• The head contractor: For defects in work carried out under the main contract — the contractor is responsible for both their own work and the work of subcontractors
• A subcontractor: If you have a direct contract with the subcontractor, or in some circumstances, a direct duty of care in tort (negligence)
• The building certifier: For failure to identify non-compliant work during inspections — certifiers owe a duty to owners and can be liable for negligent certification
• The engineer or designer: For structural or design defects arising from negligent design or specification
• The QBCC (via QHWS): For residential building work covered by the Queensland Home Warranty Scheme, if the contractor cannot be pursued

Expert Reports — The Foundation of Every Defects Claim

Building defects claims live or die on expert evidence. A building inspector or engineer’s report that identifies, quantifies, and explains the defects is essential before committing to litigation. The report should:

• Identify each defect with precision (location, nature, extent)
• State the relevant standard or code provision that was not complied with
• Estimate the cost of rectification
• Distinguish between the contractor’s defects and owner-caused damage

Boss Lawyers works with a network of qualified building consultants and forensic engineers in Brisbane and Queensland to ensure your claim is properly supported.

Remedies for Building Defects

The principal remedies for building defects are:

• Rectification: The court can order the contractor to rectify the defects, or award the cost of rectification as damages
• Diminution in value: Where the defects cannot be cost-effectively rectified, damages may be assessed as the difference between the value of the property as built and its value if properly constructed
• Consequential loss: Loss of rent, increased financing costs, or other consequential losses flowing from the defects (subject to the remoteness rule)
• Costs: In court proceedings, a successful party can generally recover a portion of their legal costs

The measure of damages depends on whether rectification is “reasonable” — courts will not award the cost of rectification if it is disproportionate to the benefit gained.

Frequently Asked Questions

What is the defects liability period?

Most standard building contracts include a defects liability period (typically 12–24 months after practical completion) during which the contractor is obliged to rectify defects at no extra charge. The defects liability period does not limit your rights after it expires — it is an additional right, not a ceiling on your claim. Statutory and contractual limitation periods are separate and much longer.

Can I claim for building defects if I’m not the original owner?

It depends. If you purchased the property after practical completion, your rights depend on whether the original contract rights were assigned to you at settlement. For residential property in Queensland, there is statutory protection under the QBCC Act and the Domestic Building Contracts Act 2000 (Qld) that extends to subsequent owners in some circumstances. Commercial property is more complex — advice is essential.

What if the contractor refuses to come back to fix defects?

If the contractor refuses to rectify defects within the defects liability period, they are in breach of contract. You are entitled to have the work rectified by another contractor at the original contractor’s cost — but you should document the breach, give notice, and obtain expert evidence before engaging a replacement contractor. Boss Lawyers can advise on the correct process to preserve your claim.
