A non-compliant residential building contract can cost Queensland contractors fines and demerit points against their license. Contractors who do domestic building work valued at more than $3,300 (including labor, materials, and GST) must comply with Schedule 1B of the Queensland Building and Construction Commission Act 1991. The requirements vary depending on contract value. Level 1 contracts range from $3,300 to $19,999.99, and Level 2 contracts cover work valued at $20,000 or more. This article steps contractors through creating QBCC-compliant contracts that meet regulatory requirements.
What Makes a Residential Building Contract Compliant in Queensland
QBCC Act Schedule 1B Overview
Schedule 1B of the Queensland Building and Construction Commission Act 1991 establishes the legal framework for domestic building contracts in Queensland. The legislation came into force on 1 July 2015 and replaced the previous Domestic Building Contracts Act 2000.
The legislation does not mandate that contractors use QBCC contracts or any specific contract template. Rather, it sets out provisions that must be part of all domestic building contracts. Contractors are responsible for ensuring that the contracts they use comply with Queensland building laws and requirements. This applies whether using standard form pre-printed contracts from QBCC or industry associations, or bespoke contracts.
Domestic Building Work Definition
Domestic building work under Schedule 1B includes the erection or construction of a detached dwelling and renovation, alteration, extension, improvement or repair of a home. The definition extends, in some cases, to removal and resiting works, and also the installation of kit ( ‘modular’) homes.
Domestic building work also includes work associated with (among others) the erection or construction of a detached dwelling. Associated work includes landscaping, paving, and the erection or construction of buildings or fixtures associated with the dwelling.
Written Contract Requirements
The Queensland Building and Construction Commission regulates all domestic building contracts above the regulated amount, which is $3,300. Written contracts for all regulated domestic building work. Each party must sign and date contracts that comply with Schedule 1B of the QBCC Act.
Contracts valued over $10,000 must be executed before work commences. Contracts below this threshold must still be in writing, but can be formalised before work completion.
Penalties for Non-Compliance
A contractor commits an offense by failing to use a written contract that complies with QBCC Act requirements for regulated building work. The Queensland Building and Construction Commission may prosecute or take regulatory action, including applying demerit points to the Contractor's license. These consequences may lead to loss of license and potential fines for the contractor.
The QBCC has the authority to take a range of actions when contractors fail to follow building and construction industry rules and has the power to inspect and investigate non-complying conduct.
Determining Your Contract Type and Requirements
Assessing Your Project Value
Contract requirements in Queensland hinge on the total project value, including labor, materials, and GST. The $3,300 mark represents the first threshold. Prices below this amount don't fall under regulated domestic building legislation, though the Queensland Building and Construction Commission recommends documenting these arrangements using their two-page Small Building Projects Contract.
Level 1 contracts apply to projects valued between $3,300 and $19,999.99. Level 2 contracts apply to projects valued above that amount. Accurate calculation of the contract price is necessary to determine which regulatory framework applies to the residential building contract.
Level 1 vs Level 2 Contract Differences
Level 1 contracts require, among other things, the contracting parties' names with the contractor's license number as it appears on their license, a description of the contracted work, the contract price or calculation method with a reasonable estimate, and the date for practical completion or how it will be determined. Additionally, plans , specifications, and a conspicuous cooling-off period notice are required. Contractors must deliver a signed contract copy to owners within 5 business days after entering the agreement.
Level 2 contracts have additional requirements. The Consumer Building Guide must be given to the owner before contract signing. A start date or its determination method becomes mandatory, not just the completion date. The contract text must include relevant statutory warranties. The contract schedule must display the contract price if fixed, or the calculation method, including allowances if not fixed. A price change warning explaining provisions that could alter the contract price must occupy a prominent position on the same first page. Contractors must provide a Commencement Notice stating when work started and the practical completion date within 10 business days of work commencing on site.
All contracts must be in writing, signed and dated.
Special Requirements for Cost Plus Contracts
Schedule 1B defines a cost plus contract as a domestic building contract where the amount the building contractor receives cannot be calculated accurately when parties enter the contract, even ignoring prime cost items and provisional sums. The homeowner pays actual costs the contractor incurs for materials and subcontractors, plus a percentage of those costs or an added fee for overheads and profit.
Cost plus contracts present risks due to the absence of price certainty. The contractor's payment claims are proportionate to total costs and there is little incentive on the builder’s part to minimise expenses. Reports to the Queensland Building and Construction Commission over many years show final costs frequently exceed owner expectations. The high incidence of disputes arising from these contracts presents a risk to both parties.
Protection for non-completion under the Queensland Home Warranty Scheme is not available to owners when cost plus contracts are used. The QBCC recommends homeowners and contractors get formal legal advice before agreeing to use cost plus contracts for domestic building work.
Construction management contracts carry similar risks, where owners sign contracts with multiple trade contractors supervised by a licensed construction manager. A breakdown in any trade contract creates flow-on impacts and exposes homeowners to delays and legal action.
Off-Site Work Considerations
Section 33 of Schedule 1B provides an exception to standard deposit rules when the off-site work value exceeds 50% of the contract price. The maximum deposit increases to 20%. This exception applies where substantial customised building work or prefabrication occurs away from the building site
Core Components of a QBCC-Compliant Residential Contract
Building disputes often occur when written agreements are poorly documented or absent. This leads to misunderstandings between contractors and owners. A residential building contract establishes the legal agreement covering work specifications, pricing, and timeframes.
Mandatory Contract Information
Every QBCC-compliant residential building contract must identify the contracting parties by name. This includes the contractor's license number as it appears on their QBCC license. The site address where work will occur needs clear documentation. Use house or unit numbers with street names, or lot and plan numbers for new estate developments. A description of the contracted work is another key element.
Price Structure and Allowances
The contract price or its calculation method must appear in the contract, and the contractor must provide a reasonable estimate. Prime cost items cover fixtures that owners select after contract signing, such as kitchen appliances or bathroom fittings. Provisional sums apply to mixed items and labor packages like excavation, pools or driveways. These allowances need reasonable estimates based on available information at contract execution. Contractors include their margin in the overall contract price.
Timeline and Completion Requirements
Level 1 contracts must specify the practical completion date or its determination method. Level 2 contracts also need a start date or determination method on the contract schedule's first page. Contractors must deliver a commencement notice confirming the start date and practical completion date within 10 business days of starting work.
Payment Schedule Setup
Deposit limits vary by contract value. Level 1 contracts allow deposits up to 10%, while level 2 contracts permit only 5% deposits. Progress payments must relate to on-site work progress and be proportionate to the completed work value. For example, contractors cannot claim 50% of the contract price until approximately 50% of the work is complete.
Insurance and Warranty Provisions
Home warranty insurance becomes compulsory for residential construction work exceeding $3,300in value. Contractors collect the premium from owners and remit payment to QBCC. The Queensland Home Warranty Scheme covers claims up to $200,000, or $300,000 with optional additional cover. Implied warranties guarantee materials are new and suitable, work follows all laws and specifications, contractors exercise reasonable care and skill, and completed homes suit occupation.
Plans, Specifications, and Approvals
Contractors must provide owners with plan drawings and specifications to ensure mutual agreement on construction details. Section 15 of Schedule 1B requires contractors to deliver a copy of the signed contract, including any plans and specifications, to homeowners within 5 business days of both parties signing the contract.
Creating Your Contract Documents Step by Step
Using Standard Form Contracts vs Custom Contracts
Contractors face two paths when creating residential building contract documents. The cheapest and simplest approach involves using standard form contracts. These contracts are drafted to meet legislative requirements, although they require tailoring to special circumstances. The QBCC provides several free standard form contracts t. Industry bodies offer alternative, typically paid, standard form contracts.
Contractors may develop custom contracts as an alternative, but assistance from a practising lawyer is suggested to ensure compliance with Queensland legislation. Outdated contracts or contracts from other jurisdictions are not appropriate for use in Queensland
Preparing the Contract Schedule
The contract schedule's first page requires a prominent display of the fixed contract price for Level 2 agreements. The calculation method, including allowances, must appear in the schedule if the price remains unfixed. A price change warning must occupy a conspicuous position and set out contract provisions that could increase or decrease the price through variations.
Documenting the Scope of Building Work
Contractors must provide a detailed description of contracted work within the agreement. This scope includes materials, quantities, labor, and associated costs.
Setting Up Compliant Payment Terms
Payment provisions must reflect the deposit limitations established above. Progress payments should be in an amount that is proportionate to the work that the payment relates.
Including Required Notices and Guides
Contractors must deliver the QBCC Consumer Building Guide before homeowners sign level 2 contracts. Contractors must give owners fully signed copies of the whole agreement, including plans and specifications, within 5 business days after entering the contract.
Finalising and Executing Your Building Contract
Pre-Signing Requirements
Contractors should check contract documentation and seek legal advice before entering residential building contracts. Building contract law in Queensland must be in writing, signed and dated by each party or their authorised representative, and compliant with Schedule 1B.
Delivering Signed Copies to Owners
Contractors must deliver signed copies of the entire contract, including plans and specifications, within 5 business days after entering the agreement. This timeline applies to both Level 1 and Level 2 QBCC contracts.
Post-Contract Obligations
Contractors must provide a signed Commencement Notice stating the start date and practical completion date within 10 business days of work commencing on site. Variation documents require delivery within 5 business days after agreement. Contractors must give owners copies of each certificate of inspection when practicable after receiving them from the certifier.
Conclusion
These requirements may seem complex at first, and you should seek legal advice if you do not understand the requirements according to the law.
Contractors who follow Schedule 1B provisions with care, include all mandatory elements, and deliver required documents on time avoid costly penalties and exposure to liability. Ultimately, legal compliance protects both parties and minimises the risk of construction disputes.

FAQs
Can contractors develop their own building contracts in Queensland?
Yes, contractors can create their own residential building contracts in Queensland, but they must ensure compliance with Schedule 1B of the QBCC Act. It's strongly recommended to obtain assistance from a solicitor when developing custom contracts to ensure legislative requirements are met. Parties bear full legal responsibility for whatever contracts they use, whether standard forms or custom documents.
What are the main types of residential building contracts in Queensland? Queensland residential building contracts are primarily categorised by project value: Level 1 contracts apply to work valued between $3,300 and $19,999.99 and Level 2 contracts cover projects valued above that amount. Additionally, there are specialised contract types, including cost plus contracts and contracts for specific purposes like natural disaster repairs or alterations and renovations.
What is the cooling-off period for residential building contracts in Queensland?
Homeowners have a cooling-off period of 5 business days during which they can withdraw from the contract. This period begins only after the owner receives both the signed contract and the Consumer Building Guide (for Level 2 contracts ).
What happens if a contractor doesn't use a compliant written contract? Contractors who fail to use a written contract that complies with QBCC Act requirements may commit an offence. The QBCC may prosecute or take disciplinary action, apply demerit points to the contractor's license, and impose fines. These consequences can ultimately lead to loss of license and significant financial consequences.
What is a cost-plus contract, and what are its risks?
A cost-plus contract is one where the homeowner pays the actual costs incurred by the contractor for materials and subcontractors, plus a percentage or fee for overhead and profit. These contracts carry significant risks as they lack price certainty, and final costs often exceed owner expectations. Additionally, protection for non-completion under the Queensland Home Warranty Scheme is not available with cost-plus contracts, making them high-risk for both parties.
