The Unique Challenges of Residential Construction Contracts
Domestic building contracts occupy a singular position within Australian construction law, governed by state-specific consumer protection legislation that imposes mandatory terms, disclosure requirements, and cooling-off periods to address the inherent power imbalance between homeowner and builder. Unlike commercial construction where parties negotiate risk allocation on more or less equal footing, residential construction is characterised by a fundamental asymmetry that pervades every stage of the project lifecycle: the homeowner typically invests their life savings or takes on substantial mortgage debt to fund what is almost certainly their largest single financial commitment, while the builder holds not only the technical knowledge and construction expertise but also the contractual leverage to shape terms in their favour. This power imbalance is precisely why every Australian jurisdiction has enacted protective legislation that overrides the general law of contract, inserting non-excludable terms and statutory warranties that cannot be contracted away no matter what the written agreement says.
In Queensland, the Queensland Building and Construction Commission Act 1991 (QBCC Act) and the Domestic Building Contracts Act 2000 (DBC Act) together govern the licensing of residential builders, mandatory contract terms that must appear in every domestic building contract, cooling-off periods that give homeowners a right of rescission, progress payment schedules with prescribed stages for regulated contracts, and the Home Warranty Scheme that provides the last-resort safety net for defective work. These state regimes are further overlaid by the Building Industry Fairness (Security of Payment) Act 2017 (BIF Act), which gives builders, subcontractors, and suppliers a statutory right to progress payments through a rapid adjudication process that exists alongside, and independent of, the underlying contract. In New South Wales, the Home Building Act 1989 establishes statutory warranties that run for defined periods — six years for structural defects and two years for non-structural defects — mandates insurance through the Home Building Compensation Fund for projects over $20,000, and prescribes non-excludable contract terms that override any inconsistent provision in the building contract. In Victoria, the Domestic Building Contracts Act 1995 imposes mandatory terms, requires written contracts for work over $5,000, prescribes a five-day cooling-off period, and establishes a dispute resolution framework through Domestic Building Dispute Resolution Victoria (DBDRV) and the Victorian Civil and Administrative Tribunal (VCAT). Navigating these distinct regulatory regimes demands specialist knowledge that generalist lawyers simply cannot provide, and that is why our dual-qualified engineer-lawyers bring a depth of expertise that bridges both the legal technicalities and the practical construction realities that shape every residential project.
Contract Review Services for Homeowners
For homeowners, signing a domestic building contract without specialist legal advice is quite possibly one of the most financially perilous decisions you will ever make. The contract you are asked to sign will almost certainly have been drafted by the builder or by an industry association that represents builders' interests — not yours. Our fixed-fee residential contract review service identifies risks before you commit, giving you the knowledge and negotiating leverage to protect your investment from the very first day. We deliver comprehensive written advice in plain English within three to five business days, because we understand that construction timelines move quickly and that every day of delay can have cascading consequences for your project.
When we review your contract, we examine every single clause through the dual lens of legal enforceability and practical construction reality — because our lawyers are also qualified engineers who understand exactly how residential projects are actually built, from slab pour through to final handover. We scrutinise the scope of work for any ambiguity or omission that could lead to dispute, assessing whether the specifications adequately describe materials, finishes, tolerances, and quality standards. We evaluate whether the variation mechanism is fair and transparent, ensuring that you will not be charged for work that was within the original scope, and that any legitimate variations are properly documented, priced, and approved before the work proceeds. We assess whether liquidated damages provisions are proportionate and enforceable — too high and they risk being struck down as a penalty, too low and they fail to provide genuine compensation for delay. We verify that extension of time provisions adequately protect the builder only against delays that are genuinely beyond their control, not those caused by their own poor planning or inadequate resourcing. We examine whether the defects liability period meets or exceeds statutory minimums, and whether the practical completion definition is clear and objective rather than leaving the builder with an escape route through subjective interpretation.
We pay particular attention to special conditions — those amendments tacked onto standard form contracts that frequently override balanced standard terms with onerous provisions favouring the builder. In our experience, special conditions are where the most aggressive risk-shifting occurs, often without the homeowner even realising what has been changed or what rights they have lost. We also verify that the contract contains all mandatory statutory protections required by the QBCC Act 1991, the Domestic Building Contracts Act 2000, and where applicable, the BIF Act 2017, because a contract that fails to include mandatory terms may be unenforceable in critical respects, leaving the homeowner without the protections the legislature intended them to have.
Beyond the contract itself, we advise on your cooling-off period rights — in Queensland, you have five business days from receiving a signed copy of the contract to terminate for any reason without penalty — and we explain how the QBCC Home Warranty Scheme protects you against defective work, the specific circumstances in which you can make a claim against the insurance policy, and the statutory warranties that apply to your building work regardless of what the contract says or fails to say. Our written advice identifies every material risk, explains its potential impact in practical terms that you can understand and act upon, and recommends specific amendments with suggested drafting that you or we can use in negotiation with the builder. If amendments are required, we can negotiate directly with the builder or their legal representative on your behalf to secure protective terms without derailing the project or souring the relationship before construction even begins.
Contract Drafting and Compliance Services for Builders
For residential builders, a well-drafted domestic building contract is simultaneously a risk management tool, a payment protection mechanism, and a commercial instrument that defines the scope, quality, and financial parameters of your relationship with the homeowner. A poorly drafted contract — or one that fails to comply with statutory requirements — can expose you to QBCC disciplinary action including licence suspension or cancellation, render your payment terms unenforceable just when you need them most, create disputed variations that erode your already tight margins, and generate protracted disputes that consume management time, damage your reputation, and divert your attention from actually building.
We draft and review domestic building contracts across all major standard forms including HIA contracts (Housing Industry Association — including the New Home Contract, Renovation/Addition Contract, and Cost Plus Contract variants), MBA contracts (Master Builders Association contracts, which vary by state and include the MBA NSW Residential Building Agreement, MBA Victoria New Home Contract, and their interstate equivalents), and ABIC contracts (both the Simple Works version for smaller residential projects and the Major Works version for more complex residential construction). For each contract we ensure full compliance with the QBCC Act 1991, including mandatory disclosure requirements that must be provided to the homeowner before the contract is signed, prescribed progress payment stages for regulated contracts over $20,000 that must not be departed from without risking regulatory action, minimum defects liability periods that vary depending on the nature of the defect, and proper termination procedures that protect your right to suspend or terminate while avoiding the pitfalls of wrongful termination that can expose you to substantial damages.
We draft special conditions that protect your legitimate commercial interests — covering latent site conditions that could not reasonably have been anticipated, provisional sum allowances for work whose scope cannot be precisely determined at the time of contracting, protocols for owner-caused delays that disrupt your programming and increase your costs, and enforcement of payment claims under the BIF Act 2017 — while remaining fair enough to present to homeowners without causing unnecessary friction or deterring them from signing. Our special conditions are drafted with precision to avoid the ambiguity that so often leads to dispute, and we ensure they are consistent with the standard form terms rather than creating internal contradictions that courts will resolve against the drafter.
Our services for builders extend well beyond contract drafting. We advise on progress claim structures that comply with the statutory payment framework while maximising your cash flow position throughout the construction period. We develop variation procedures that capture every legitimate change to scope before the work proceeds, ensuring that the contract variation mechanism is triggered promptly and that proper written authorisation is obtained so that disputes about whether work was a variation, and what it should cost, do not arise months later. We prepare extension of time claim procedures that preserve your entitlement to relief from delay events beyond your control, with template notices and claim submissions that comply with both the contract and the statutory framework. We manage defects liability period obligations, advising on the critical distinction between structural defects — which in Queensland carry a six-year liability period — and non-structural defects — which carry a twelve-month liability period under the QBCC Act — and ensure your maintenance obligations are clearly defined and time-limited so that you are not carrying open-ended liability for minor cosmetic issues indefinitely. For builders facing regulatory scrutiny, we provide defence representation in QBCC disciplinary proceedings, Show Cause Notice responses, licence suspension and cancellation matters, and Home Warranty Insurance claims, drawing on our deep understanding of the QBCC regulatory framework and our practical construction expertise to mount the strongest possible defence and protect the licence upon which your entire business depends.
The Homeowner's Guide to Building Contracts
Before you sign any domestic building contract, there are fundamental matters you must understand and verify, because once you sign, your rights to negotiate change dramatically. First and foremost, ensure that your builder holds a current QBCC licence — or the equivalent in your state — with the correct licence class for the work they propose to undertake. You can verify this online through the QBCC licence search portal, and you should do so before you pay any deposit or sign any document. An unlicensed builder cannot lawfully perform residential construction work, and any contract with an unlicensed builder may be void, leaving you without the protections of the statutory insurance scheme and potentially unable to recover your losses.
Understand your cooling-off period rights. In Queensland, the Domestic Building Contracts Act 2000 gives you five business days from receiving a signed copy of the contract to terminate for any reason whatsoever — you do not need to provide any justification. If you exercise this right, the builder may retain only a prescribed termination fee, which is currently the lesser of $100 or 0.2% of the contract price. This cooling-off period is your last opportunity to have the contract reviewed by a specialist construction lawyer before you are fully committed, and we strongly encourage every homeowner to use this window wisely. Be aware, however, that the cooling-off period can be lost if you obtain independent legal or financial advice before signing and provide a certificate to that effect, or if the contract is signed more than thirty days after you received the prescribed documents.
Verify that your builder has obtained the required Home Warranty Insurance — known in Queensland as the QBCC Home Warranty Scheme and in New South Wales as cover through the Home Building Compensation Fund. For work over $3,300 in Queensland, builders must pay the insurance premium and provide you with a certificate of insurance. This insurance provides cover of up to $200,000 for defective work and up to $5,000 for non-completion, and it runs for six years and six months from the date of practical completion. Without this insurance, you have no safety net if the builder becomes insolvent, abandons the project, or produces defective work that they refuse or are unable to rectify.
Understand the statutory warranties that apply to your building work regardless of what the contract says. Under the QBCC Act 1991, every domestic building contract includes implied warranties that the work will be performed with due care and skill, that all materials will be good and suitable for their purpose, that the work will be performed in accordance with the plans and specifications set out in the contract, and that the work will be performed in accordance with all relevant laws and legal requirements including the Building Act 1975. These warranties cannot be excluded, limited, or modified by any contract term, and they provide a statutory cause of action that runs independently of the contract itself.
Before signing, you should also understand the progress payment schedule and ensure it complies with the statutory framework. For regulated contracts over $20,000 in Queensland, the builder cannot demand payment exceeding the prescribed percentages at each stage — slab or base stage, frame stage, lock-up or enclosure stage, fixing or fit-out stage, and practical completion. The builder cannot demand a deposit exceeding the prescribed amount, and any provision requiring payment before work is performed to the relevant stage is void. At practical completion, understand exactly what this means — it is the stage when the building work is complete except for minor omissions and defects that do not prevent the building from being used for its intended purpose. Do not let a builder pressure you into signing a practical completion certificate before you are genuinely satisfied that the work is substantially complete. Once practical completion is achieved, the defects liability period begins — twelve months for non-structural defects and six years for structural defects in Queensland — during which the builder must rectify any defects that appear. If things go wrong at any stage, document everything in writing, communicate through email rather than verbal discussions, keep contemporaneous records of all site meetings and conversations, and seek specialist legal advice before taking any formal step that might compromise your position.
Builder's Compliance Guide
For builders operating in the residential sector, compliance with the regulatory framework is not optional — it is a condition of maintaining your licence and your ability to trade. The consequences of non-compliance can be severe, ranging from financial penalties through to licence suspension or cancellation, uninsured liability, and unenforceable contracts that leave you without payment protection. Your QBCC licence must be current and held in the correct class for the work you undertake. If your licence is a contractor's licence, you must ensure it remains free of conditions that restrict your ability to perform domestic building work, and you must meet the QBCC's financial reporting requirements including minimum net tangible asset thresholds that vary depending on your annual turnover.
You must use an approved contract form for all domestic building work. In Queensland, the Domestic Building Contracts Act 2000 requires that regulated contracts — generally those over $3,300 — must be in writing and must contain all mandatory terms prescribed by regulation. These mandatory terms include the identity of the parties, a description of the work, the contract price or an appropriate mechanism for calculating it, the commencement and completion dates, the progress payment schedule, the defects liability period, and prescribed warnings and notices. You cannot simply use a generic commercial contract or a document downloaded from the internet and expect it to comply. The contract must also include all mandatory disclosure documents, including the Consumer Building Guide and, where required, a written checklist verifying that the homeowner has read and understood key aspects of the contract.
Your insurance obligations are absolute. For work over $3,300 in Queensland, you must pay the QBCC Home Warranty Insurance premium and provide the homeowner with a certificate of insurance before taking any deposit or commencing work. Failing to do so is not merely a compliance failure — it can render you liable to disciplinary action and leave you personally exposed for any claims that the insurance would otherwise have covered. Your progress claims must comply precisely with the statutory payment framework for regulated contracts over $20,000. You cannot front-load payments to improve your cash flow position, and you cannot demand payment for stages that have not been reached. The prescribed maximum percentages at each stage are not suggestions — they are mandatory limits, and any clause requiring payment in excess of those limits is void.
When it comes to variations, you must follow the procedure prescribed by the Domestic Building Contracts Act 2000. A variation must be in writing and signed by both parties before the variation work is commenced, except in limited circumstances where urgent work is necessary to prevent damage or for safety reasons. You cannot simply perform additional work and then bill for it later, hoping the homeowner will pay. If the variation increases the contract price by more than the statutory threshold — currently 10% of the original contract price or $3,300, whichever is greater — additional procedural requirements are triggered including a further cooling-off period. Dispute notification requirements must also be observed. If a dispute arises, you must follow any dispute resolution procedure set out in the contract, and in Queensland you must notify the QBCC within the prescribed timeframes if the dispute relates to defective work, non-completion, or other matters within the QBCC's jurisdiction.
The most common compliance failures we see include using outdated contract forms that do not reflect current legislative requirements, failing to provide mandatory disclosure documents, front-loading progress payments beyond statutory limits, performing variations without proper written authorisation, failing to maintain adequate insurance coverage, and missing critical deadlines for notifying the QBCC of disputes. Each of these failures can be avoided with proper systems, training, and specialist legal support.
HIA vs MBA vs ABIC — Which Contract Is Right?
The choice of contract form is one of the most important decisions in any residential construction project, yet it is frequently made without adequate consideration of the differences between available options. The three dominant standard form families in Australian residential construction — HIA, MBA, and ABIC — each have distinct characteristics, strengths, and weaknesses that make them more or less appropriate depending on the nature of the project, the jurisdiction, and the relative sophistication of the parties.
HIA contracts, published by the Housing Industry Association, are the most widely used contract forms in Australian residential construction and are available in several variants tailored to different project types. The HIA New Home Contract is designed for new dwelling construction and is the form most commonly presented to homeowners by project home builders. The HIA Renovation/Addition Contract is specifically drafted for alterations and additions to existing dwellings, with provisions that address the unique challenges of working within an occupied home and connecting to existing structures. The HIA Cost Plus Contract is intended for projects where the final cost cannot be accurately determined at the time of contracting, providing a mechanism for the builder to recover actual costs plus an agreed margin. HIA contracts are generally builder-favourable in their standard form, and homeowners should be particularly vigilant about the special conditions that are frequently added. Common problems with HIA contracts include vague specification documents that leave material selections undefined, progress payment schedules that may not comply with statutory requirements in all jurisdictions, and special conditions that override balanced standard terms.
MBA contracts, published by the Master Builders Association, are state-specific and reflect the legislative requirements of each jurisdiction in which they are published. The MBA NSW Residential Building Agreement, MBA Victoria New Home Contract, and their counterparts in Queensland, Western Australia, South Australia, and Tasmania each incorporate the mandatory terms and disclosure requirements of their respective state legislation. MBA contracts tend to be more balanced than HIA contracts in their standard form, but like all standard forms they are frequently modified by special conditions that shift risk. The state-specific nature of MBA contracts means that a contract form appropriate in New South Wales may not comply with the requirements of Queensland law, and builders operating across multiple states must ensure they are using the correct form for each jurisdiction. Common problems with MBA contracts include special conditions that add onerous requirements beyond the standard form, inadequate addressing of latent conditions, and unclear practical completion definitions.
ABIC contracts, published jointly by the Australian Institute of Architects and Master Builders Australia, are specifically designed for projects where an architect is engaged to administer the contract on behalf of the owner. The ABIC Simple Works Contract is suitable for smaller residential projects with a relatively straightforward scope, while the ABIC Major Works Contract is designed for larger, more complex residential construction where the architect's role in design development, contract administration, and certification is more involved. ABIC contracts are generally the most balanced of the three families because they are intended for use where the owner has professional representation through the architect. However, they require competent administration by the architect, and the quality of contract administration can significantly affect how smoothly the project proceeds. Common problems with ABIC contracts include architects who lack the experience or confidence to properly administer the contract, unclear boundaries between the architect's design responsibility and the builder's construction responsibility, and disputes about the architect's certification of progress claims and practical completion.
The right contract form depends on the specific circumstances of your project. For straightforward new home construction with a project builder, an appropriately reviewed HIA or MBA contract will typically suffice. For renovations and additions where the existing structure introduces complexity, the HIA Renovation/Addition Contract or the relevant MBA form with carefully drafted special conditions is usually appropriate. For architect-designed homes where professional contract administration is available, the ABIC Major Works Contract provides the most sophisticated framework. For all project types, however, specialist legal review before signing is essential to ensure that the contract, in its final form with all special conditions, adequately protects your interests and complies with the applicable legislative requirements.
Common Issues We Address in Domestic Building Contracts
Over three decades of practice spanning thousands of residential construction matters, we have identified the same recurring problems that predictably lead to disputes, cost overruns, damaged relationships, and litigation that consumes years and exhausts both parties. Vague or incomplete scope of work is by far the most common source of residential construction disputes, where poorly defined specifications leave critical decisions about materials, finishes, fixtures, fittings, and inclusions unresolved until the parties discover — usually at the worst possible moment — that they hold fundamentally different expectations about what is being built. A specification that says "premium kitchen" without defining what "premium" means, or "quality paint finish" without specifying the brand, colour, number of coats, and surface preparation requirements, is an invitation to dispute.
Unfair risk allocation arises when contracts shift unreasonable burdens onto homeowners — such as making them liable for delays caused by the builder's own subcontractors, or requiring them to obtain approvals that are properly the builder's responsibility — or onto builders through liquidated damages that are disproportionate to the actual likely loss and may be unenforceable as penalties. Inadequate variation procedures create havoc when changes to design, unforeseen site conditions, or evolving homeowner preferences are not properly documented, priced, and approved before work proceeds, leading to bitter disputes about whether the work was a variation at all, whether the homeowner authorised it, and what it should reasonably cost. Unreasonable liquidated damages clauses — set too high and potentially unenforceable as penalties under the rule established in Peninsula Balmain Pty Ltd v Abigroup Contractors Pty Ltd, or too low and failing to provide genuine compensation for the actual losses a delayed completion causes — require careful scrutiny and calibration against the specific circumstances of each project.
Missing or deficient extension of time provisions leave builders exposed to damages for delays caused by latent site conditions, owner-directed changes, inclement weather beyond seasonal norms, trade shortages, or delays in the delivery of owner-supplied materials or fixtures. Poorly drafted special conditions frequently undermine the balanced risk allocation of standard form contracts, introducing ambiguity and internal contradiction rather than the clarity they are intended to provide. Non-compliance with statutory requirements can render entire contracts unenforceable and expose builders to QBCC disciplinary action, licence suspension, or cancellation. Finally, inadequate dispute resolution clauses that fail to prescribe a clear graduated pathway from direct negotiation through mediation to formal determination can escalate minor disagreements into major litigation simply because no agreed mechanism for early resolution exists, allowing grievances to fester and positions to harden until they become irreconcilable.
Case Study — The Incomplete Extension That Cost $180,000
In 2022, we were engaged by a homeowner in Brisbane's inner-western suburbs who had signed an HIA Renovation/Addition Contract for a $450,000 two-storey extension to their Queenslander home. The project included a new master bedroom with ensuite, an expanded living area, a covered deck, and a new garage. The builder — a mid-tier operator with a seemingly solid reputation — had completed approximately 70% of the work when he abruptly abandoned the site, citing financial difficulties. The homeowner was left with a partially completed extension, exposed framing, incomplete weatherproofing, and a young family living in a construction zone with no clear path forward.
When the homeowner came to us, they had already paid $380,000 — well in excess of the value of work actually completed — and had been told by the builder that he would not be returning. The homeowner's priority was threefold: recover the overpayment, secure funding to complete the project, and hold the builder accountable. We immediately conducted a comprehensive assessment of the homeowner's position under the Domestic Building Contracts Act 2000 and the QBCC Act 1991, and we simultaneously engaged a quantity surveyor to assess the value of work completed and the cost of completing the remaining work. The assessment revealed that the builder had overclaimed on progress payments by approximately $85,000, and that the cost of engaging a new builder to complete the work would be $130,000 — $65,000 more than the original contract price for the remaining scope, largely due to the inefficiency and risk premium of taking over a partially completed project.
We lodged a complaint with the QBCC and simultaneously made a claim on the homeowner's Home Warranty Insurance policy for non-completion. The QBCC investigation substantiated our client's claims and resulted in a Direction to Rectify being issued to the builder, which he failed to comply with — triggering further disciplinary consequences for his licence. The Home Warranty Insurance claim resulted in a payment of $50,000 toward the cost of completion, which represented the maximum non-completion cover available under the policy at that time. We then commenced proceedings in the Queensland Civil and Administrative Tribunal (QCAT) against the builder for recovery of the overpaid progress payments, the additional cost of completion, and general damages for breach of contract. The builder's defence — that the homeowner had caused delays by changing their mind about finishes — was comprehensively rebutted through contemporaneous correspondence and site records that demonstrated all variations had been properly documented and the homeowner had made every decision within the timeframes required by the contract.
The matter ultimately resolved at mediation, with the builder agreeing to pay $130,000 in settlement — covering the overclaimed progress payments and a significant portion of the additional completion costs — without the need for a contested hearing. With the insurance payment and the settlement, the homeowner was able to engage a new builder, complete the extension to the original specification, and finally move their family into the home they had planned. The entire process took fourteen months from our engagement to practical completion of the remedied work, a timeline that reflects the complexity of coordinating insurance claims, regulatory proceedings, and litigation — but the outcome demonstrates that with specialist legal representation, homeowners can recover from even the most distressing builder abandonment scenarios.
Our Domestic Building Contract Review Process
Our process is designed to be thorough, efficient, and completely transparent from the moment you first contact us. It begins with an initial consultation, typically conducted by telephone or video conference at a time that suits your schedule, during which we discuss your project, your concerns, the timeline you are working within, and the contract requiring review or drafting. This consultation allows us to understand the specific context of your matter, identify any urgent deadlines such as cooling-off period expiry dates, and provide preliminary guidance on the issues we anticipate encountering. There is no charge for this initial consultation, and it carries no obligation to proceed with our services.
Following this, we conduct a comprehensive document review, examining every clause of the contract against the applicable statutory framework and your specific risk profile, researching any novel legal issues that arise, verifying compliance with current legislation including any recent amendments to the QBCC Act, the DBC Act, or the BIF Act, and assessing the practical construction implications of the contract terms through the lens of our engineering expertise. We also review any associated documents — plans, specifications, engineering drawings, soil reports, and BASIX or NatHERS certificates — that form part of the contractual package and may contain obligations or assumptions that affect the risk allocation.
We then prepare detailed written advice that sets out our findings in plain English accessible to clients without legal training, identifies every material risk we have found, explains its potential impact in practical terms with reference to the specific circumstances of your project, and recommends specific amendments with suggested drafting where appropriate. Our advice does not simply list problems — it provides solutions, with carefully crafted alternative clause wording that you can present to the builder or that we can present on your behalf. If amendments are required, we proceed to amendment drafting, preparing precise contractual language that addresses identified risks while maintaining the commercial viability of the agreement and preserving the working relationship between the parties. Where negotiations with the other party are necessary, we provide negotiation support — representing you in direct discussions with the builder or their legal representative, or advising you behind the scenes as you conduct your own negotiations, whichever approach you prefer. Throughout the entire process, you deal directly with a dual-qualified engineer-lawyer who understands both the legal principles and the practical realities of residential construction, and who can answer your questions and address your concerns as they arise.
Frequently Asked Questions About Domestic Building Contracts
Do I really need a lawyer to review my domestic building contract, or can I rely on the builder's assurance that it's a standard form?
We would strongly advise against relying on the builder's assurances alone. "Standard form" simply means that the contract is published by an industry association and is in common use — it does not mean that the terms are fair, balanced, or protective of your interests. In fact, standard form contracts are drafted by and for the building industry, and they are frequently modified by special conditions that significantly alter the risk allocation. A specialist construction lawyer will identify risks that you would not know to look for, explain the practical implications of clauses that appear innocuous but may have serious consequences, and ensure that mandatory statutory protections are present and effective. The cost of a contract review is a tiny fraction of the value of your building project and represents one of the most cost-effective risk management investments you can make.
What happens if my builder does not have a current QBCC licence?
If your builder does not hold a current QBCC licence with the correct licence class, they are not lawfully entitled to perform residential construction work in Queensland. Any contract with an unlicensed builder may be void, and you may have no entitlement to make a claim under the Home Warranty Scheme if defects or non-completion arise. You should never sign a contract or pay any money to a builder until you have independently verified their licence status through the QBCC's online licence search. If you discover after signing that your builder is unlicensed, you should seek specialist legal advice immediately, as you may have rights to recover any monies paid and to terminate the arrangement.
Can the builder make me pay for variations that I did not approve in writing?
Under the Domestic Building Contracts Act 2000, a variation must generally be agreed in writing and signed by both parties before the variation work is commenced. There are limited exceptions for urgent work necessary to prevent damage or for safety reasons, but even in those circumstances the builder must provide a written variation as soon as practicable after the work is done. If a builder performs work that you did not approve and then demands payment, you may have a defence to that claim, particularly if the work was outside the scope of the original contract and the proper variation procedure was not followed. However, these disputes are fact-specific and can become complex, so specialist legal advice is essential.
How long do I have to make a claim if I discover defects after practical completion?
The time limits for defect claims depend on the nature of the defect. In Queensland, the QBCC Act 1991 distinguishes between structural defects — which carry a six-year liability period from the date of practical completion — and non-structural defects, which carry a twelve-month liability period. You can make a claim under the Home Warranty Insurance Scheme within six years and six months from practical completion, provided the builder was licensed and the required insurance was in place. It is critical that you notify the builder of defects in writing as soon as you discover them, and that you do not delay in seeking legal advice if the builder refuses to rectify, as limitation periods are strict and missing them can extinguish your rights entirely.
