What is the QBCC and Why Does It Matter for Your Home?
Introduction to the Queensland Building and Construction Commission (QBCC)
For anyone planning to build a new home, undertake significant renovations, or even install a swimming pool in Queensland, the name "QBCC" will quickly become familiar. In simple terms, the QBCC is the Queensland Government's independent statutory authority—the official regulator for the state's building and construction industry.
Its primary mission is to ensure the industry maintains high standards of conduct and quality, providing vital consumer protection for homeowners. Whether you're dealing with builders, carpenters, plumbers, or certifiers, the QBCC sets the rules they must follow. Understanding its role is crucial because it provides a safety net, a set of standards, and a clear path for resolving issues should they arise during your project.
The Legal Foundation: Key Legislation Governing the QBCC
The QBCC doesn't create rules on a whim; its authority and functions are established and governed by several key pieces of state legislation. The primary act that establishes its power and outlines its responsibilities is the Queensland Building and Construction Commission Act 1991 (QBCC Act).
For a complete picture of the regulatory landscape, it's also important to know that the QBCC operates under other critical acts, including:
Building Act 1975
Plumbing and Drainage Act 2018
Building Industry Fairness (Security of Payment) Act 2017
These laws collectively empower the QBCC to license contractors, enforce building standards, and protect homeowners throughout their construction journey.
The QBCC's Core Functions: How They Protect Homeowners
The QBCC's responsibilities are broad, but they can be broken down into three core functions that directly benefit and protect you as a homeowner.
Licensing and Regulation
One of the QBCC's most critical roles is ensuring that the tradespeople working on your home are qualified, licensed, and hold the necessary insurance. To legally carry out most types of domestic building work in Queensland, a person or company must hold an appropriate QBCC licence. This process verifies their technical qualifications, experience, and financial stability.
Using a licensed contractor is non-negotiable for your protection. The QBCC actively pursues and penalises individuals and companies performing unlicensed work. In fact, the QBCC's Compliance and Enforcement Branch has prioritized regulatory resources to focus on the prosecution of unlicensed contracting offences in 2023-2024, demonstrating their commitment to removing unlawful operators from the industry.
Setting Standards and Compliance
The QBCC is responsible for setting and enforcing the technical standards for all building and plumbing work across the state. This ensures that your home is built to be safe, healthy, and durable. These standards are primarily outlined in the National Construction Code (NCC) and the Queensland Development Code (QDC), which cover everything from structural integrity and fire safety to waterproofing and energy efficiency.
To ensure these standards are met, the QBCC actively audits and investigates compliance. Its oversight extends to the work of private building certifiers, who are responsible for assessing building work against legal requirements. In 2023-2024, the QBCC finalized 147 investigations into building certifiers, including 117 complaints, 27 assessment audits and 3 technical audits (QBCC Annual Report 2023-24), holding them accountable for their critical role. Similarly, in the same period, the QBCC closed 74 investigations related to plumbing and drainage work (QBCC Annual Report 2023-24), ensuring these essential services meet the required codes.
Consumer Protection and Dispute Resolution
Even with the best planning, disputes can arise. The QBCC provides a structured framework for resolving conflicts between homeowners and contractors. This can range from informal mediation to formal directions to rectify defective work.
A cornerstone of this protection is the Queensland Home Warranty Scheme (QHWS). This statutory insurance scheme provides a safety net for homeowners if their licensed contractor fails to complete the project, fails to fix defects, or if the company goes into liquidation. We will explore this scheme and the process for lodging a complaint in greater detail later in this guide.
Before You Build: Key QBCC Safeguards for Your Project
Before the first slab is poured or a single wall is framed, the most important work you can do is your due diligence. The QBCC provides several critical tools and safeguards to protect you from the very beginning of your project.
Verifying Your Builder's Licence
Your first and most crucial step is to verify that any builder or tradesperson you consider hiring holds a current and appropriate QBCC licence. This simple check can save you from significant financial loss and heartache. The QBCC provides a free, instant online search tool for this purpose.
Here’s how to use it and what to look for:
Visit the QBCC Licence Search: Navigate to the official QBCC Licence Search Tool.
Enter the Details: You can search by the individual's name, the company name, or their licence number.
Review the Results: Carefully check the following:
Licence Status: Is it active, suspended, or cancelled?
Licence Class: Does their licence class (e.g., Builder - Low Rise, Carpenter) cover the scope of work you require?
Disciplinary Record: The search will show any past disciplinary actions or conditions placed on their licence. This is a major red flag.
Never engage a contractor whose licence is not current or appropriate for your job.
The Queensland Home Warranty Scheme (QHWS)
The QHWS is arguably the most important consumer protection mechanism offered by the QBCC. It is a form of statutory insurance designed to protect homeowners from major losses. For most domestic building work valued over $3,300, the licensed contractor is legally required to pay a premium to the QBCC for this insurance on your behalf before work commences.
Here’s what the QHWS covers:
Non-Completion: If your builder dies, disappears, or becomes insolvent (e.g., enters liquidation) and cannot finish the job, the scheme may cover the cost of completing the work.
Defective Work: The scheme provides coverage for rectifying defects if the contractor fails to do so under a QBCC direction, or has died, disappeared, or become insolvent.
Subsidence or Settlement: It also covers issues related to the settling or sinking of the building.
The coverage period is six years and six months from the date the work is completed, or the contract is terminated. This period covers structural defects for the full term and non-structural defects for the first 6 months after completion.
Importantly, the government is continually refining these protections. Stemming from a QCAT decision, proposed amendments to the QBCC Act (introduced in June 2025) will clarify that QHWS coverage extends to informal or oral agreements (common law contracts), ensuring homeowners are protected even when a formal written contract isn't in place.
Understanding Your Domestic Building Contract
For any domestic building work valued over $3,300, the QBCC Act mandates that the contract must be in writing. This document is your project's blueprint and legal foundation. The QBCC sets out what must be included in these builders contracts to ensure they are fair and transparent.
Key elements to check before you sign include:
Full Scope of Work: A detailed description of all work to be performed, including plans and specifications.
Contract Price: The total price or the method for calculating it (e.g., for a cost-plus contract).
Warnings and Notices: The contract must include specific consumer warnings required by the QBCC.
Cooling-Off Period: You have a right to a cooling-off period after receiving a signed copy of the contract.
Navigating the complexities of these documents can be challenging. To learn more, read our guide on navigating residential building contracts.

During Construction: QBCC Oversight and Building Standards
Once your project is underway, the QBCC's role shifts to oversight and enforcement, ensuring that the work on site complies with Australian standards and that the contractual process is followed correctly.
Building Approvals and Certification
All regulated building work requires a building approval from a licensed building certifier before it can start. While these are often private certifiers engaged by your builder, they are licensed and regulated by the QBCC. Their job is to independently assess the plans and the construction work against the building codes.
This involves conducting mandatory inspections at key stages of construction, such as:
Foundation/Slab: Before the concrete is poured.
Frame: When the building's frame is complete but before it is covered.
Final: Upon completion of all building work to ensure it is fit for occupation.
As the homeowner, you have the right to receive copies of all inspection certificates and the final certificate of inspection. This documentation is crucial for proving compliance and for the final handover of your home.
Managing Variations and Payments
It's common for changes to occur during a build. However, any variation to contract must be handled formally. The QBCC requires that all variations be put in writing and signed by both you and the builder before the work is carried out. This prevents disputes about cost and scope later on.
Payments are typically made in stages, known as progress payments, which should be clearly outlined in your contract's payment schedule. The rules under the QBCC Act protect you from being asked to pay too much upfront or for work that has not yet been completed. Recent changes, including the Building Industry Fairness (Security of Payment) Act, have introduced mechanisms like Project Trust Accounts on larger projects to further protect money paid by homeowners and ensure subcontractors are paid.
Your Rights and Responsibilities on Site
As the property owner, you have certain rights and responsibilities during the construction phase. You are entitled to reasonable access to the site to view the progress of the work, provided you coordinate with your builder and follow all safety requirements.
Effective communication is key.
Keep a detailed record of your project by:
Taking regular photos of the progress and any areas of concern.
Keeping all communication in writing, such as emails, to confirm discussions.
Documenting any conversations with a follow-up email summarising what was agreed upon.
This documentation will be invaluable if a dispute arises later.
When Things Go Wrong: Navigating Disputes and Defects with the QBCC
Despite careful planning, issues like defective work or contractual disagreements can occur. When you can't resolve a problem directly with your builder, the QBCC provides a formal, multi-stage process to help protect your investment. Acting quickly is essential, as strict time limits apply.
Early Dispute Resolution (EDR)
The first step in the QBCC's process is Early Dispute Resolution (EDR). This is a free service designed to resolve issues without resorting to formal, and often costly, legal action.
The EDR process involves a QBCC Dispute Resolution Officer who acts as an impartial facilitator. They will review the information from both you and the contractor to understand the issues. The goal is to open a clear line of communication and guide both parties toward a mutually acceptable agreement to resolve the dispute. This could involve agreeing on a scope of rectification works, a timeline for completion, or clarifying a contractual misunderstanding.
Lodging a Formal Complaint
If EDR is unsuccessful or inappropriate for your situation, you can lodge a formal complaint with the QBCC. This is the necessary step to trigger a formal investigation and potential regulatory action.
You can lodge a complaint for issues such as:
Defective building work that doesn't meet the required standards.
Incomplete work that was included in your contract.
Subsidence or sinking of the building.
It is critical to be aware of the strict time limits, which are essential for protecting your rights under the Queensland Home Warranty Scheme.
You must lodge your complaint with the QBCC within the following timeframes:
For non-structural defects: Within 7 months of the completion date.
For structural defects: Within 3 months of noticing the defect.
For structural defects, the timeframe is longer, but you should always act as soon as possible.
The process involves submitting a formal complaint form along with all your supporting evidence, including your contract, photos, emails, and any expert reports you may have. The QBCC will then assess your complaint, and if it is accepted, a Building Inspector may be assigned to conduct a site inspection to verify the alleged defects.
The QBCC Direction to Rectify
If the QBCC inspector investigates and agrees that the work is defective or incomplete, they can issue a formal "Direction to Rectify" to the contractor. This is a legal order that specifies the exact work the contractor must complete or fix, and the timeframe in which they must do it.
A Direction to Rectify is a powerful tool. The contractor has a legal obligation to comply. Failure to do so can result in significant consequences, including fines, demerit points, and suspension or cancellation of their licence. This provides a strong incentive for the contractor to return and fix the issues properly.
Making a Home Warranty Scheme Claim
You can make a claim under the Queensland Home Warranty Scheme (QHWS) when the formal process with your builder has failed. This is your ultimate safety net.
A claim can typically be made if:
The contractor fails to comply with a Direction to Rectify.
The contractor's licence has been suspended or cancelled.
The contractor has become insolvent (e.g., gone into liquidation or bankruptcy), died, or disappeared.
To make a claim, you will need to provide extensive documentation to the QBCC, proving the defect or non-completion and the failure of the contractor to resolve it. If your claim is approved, the scheme may pay for another licensed builder to complete or rectify the work, up to the policy's coverage limit.
If you disagree with a decision made by the QBCC regarding your complaint or warranty claim, you may have the right to appeal. These appeals are heard by the Queensland Civil and Administrative Tribunal (QCAT), an independent body that reviews administrative decisions.
Staying Current: Major 2024-2025 Updates to QBCC Legislation (Updated September 2025)
The building and construction industry is constantly evolving, and the laws that govern it are regularly updated to improve fairness and consumer protection. Several recent and upcoming changes to QBCC legislation are important for homeowners to be aware of.
Building Industry Fairness and Other Legislation Amendment Act 2024
This Act, which commenced on 1 July 2024, introduces significant reforms, many of which stem from recommendations made in the 2022 QBCC governance review. A key change for homeowners with larger projects is the simplification of the trust account framework. This framework is designed to protect money paid by homeowners and ensure it flows down to the subcontractors doing the work. For homeowners, this means more streamlined and robust financial protections, reducing the risk of your money being lost if a builder faces financial difficulty.
Queensland Building and Construction Commission and Other Legislation Amendment Bill 2025
This Bill was introduced to Parliament in June 2025 and is focused on modernising the QBCC's operations to make it more efficient and user-friendly. Key changes include enabling digital licensing and a wider range of electronic services, along with streamlined workplace health and safety incident reporting. For homeowners, this means easier and faster digital interactions with the QBCC and its licensees. Digital licensing is already being rolled out in stages throughout late 2025, making it simpler to check licences, lodge forms, and access information online through the Queensland Digital Licence app.
Queensland Government Building Regulation Changes (February 2025)
In a significant policy shift implemented in February 2025, the government announced a pause on the rollout of future phases of the Project Trust Account (PTA) framework, which was set to expand to more private sector projects below $10 million. While the existing framework remains, this pause means the enhanced financial protections of PTAs will not be extended to smaller residential projects in the immediate future. Additionally, the changes include the removal of the need for certain licensees (specifically Self-Certifying 1 and 2 individual licensees) to submit annual financial reports to the QBCC, a move that came into effect in March 2025 and affects approximately 50,000 licensees. This change is intended to reduce the regulatory burden on contractors. Homeowners should remain vigilant about their builder's financial health and ensure their contract has a clear progress payment schedule.

FAQs
How do I check if my builder has a QBCC licence?
You can perform a free, instant online search using the QBCC's official Licence Search Tool on their website. You can search by the builder's name, company name, or licence number. The search will show if the licence is active, what class of work it covers, and if there are any disciplinary actions on their record.
What is the Queensland Home Warranty Scheme and do I have to pay for it?
The Queensland Home Warranty Scheme (QHWS) is a statutory insurance that protects homeowners against non-completion, defective work, and subsidence if their builder dies, disappears, or becomes insolvent. The licensed contractor is legally required to pay the insurance premium to the QBCC on your behalf for most domestic building work valued over $3,300. The cost is included in your overall contract price.
What should I do if I find a defect in my new home?
First, notify your builder in writing as soon as you notice the defect, providing photos and a clear description. This gives them the opportunity to rectify it. If they are unwilling or unable to fix the issue, you should contact the QBCC to discuss their Early Dispute Resolution service or lodge a formal complaint. Remember, strict time limits apply, so it's crucial to act promptly.
Are there time limits for lodging a complaint with the QBCC?
Yes, there are critical time limits to protect your rights under the Queensland Home Warranty Scheme. You must lodge a complaint with the QBCC within these deadlines:
For non-structural defects: You must lodge a complaint within 7 months of the completion date.
For structural defects: You must lodge a complaint within 3 months of noticing the defect.
Acting immediately is the best practice.
What's the difference between a private certifier and the QBCC?
A private certifier is a licensed professional hired to assess building plans and inspect construction work at key stages to ensure it complies with the National Construction Code and other standards. They issue the building approval and final inspection certificate. The QBCC is the government regulator that licenses and oversees the certifiers, builders, and other trades. The QBCC sets the industry-wide rules, handles licensing, and resolves disputes, while the certifier's role is specific to the compliance of your individual project.
