July 2020 Consumer Building Guide Mandatory information for consumers Builders and tradespeople must give you a copy of this guide before entering into a contract for residential building work that costs more than $5,000. Read this guide to help protect your rights, carry out your responsibilities and support your building project. Protecting consumers under home building laws NSW Fair Trading is the NSW Government agency regulating residential building work (including building or trade work on single dwellings, villas, houses and home units) under the Home Building Act 1989 . What to consider before work starts Licensing Licensing requirements include: ● tradespeople and builders carrying out residential building work valued at more than $5,000 must be licensed by NSW Fair Trading (check a licence on the Fair Trading website or by calling 13 32 20) ● regardless of the work's cost, a licence is always required for specialist work (like plumbing, air conditioning and refrigeration, electrical work and gasfitting) ● if the work requires more than one tradesperson, you need a builder to manage the building project and co-ordinate the tradespeople, such as plumbers, painters and carpenters. Home Building Compensation Scheme The State Insurance Regulatory Authority (SIRA) regulates home building compensation (HBC) cover in NSW. HBC cover is required where work is worth more than $20,000 (including labour and materials). The builder or tradesperson must give you evidence of HBC cover before they start work on your project or you pay them any money, including a deposit. For more information or to check the validity of your cover, visit sira.nsw.gov.au or call 13 10 50. Approvals To help your building project go smoothly: ● check with your local council or an accredited private certifier on approvals your building work needs ● engage a building certifier. This is your responsibility, not the builder´s. Contracts and payments All contracts must be in writing . The two main contract types are: ● fixed price or lump sum - where the builder or tradesperson agrees upfront to a fixed amount for the whole job. Unforeseen changes during construction may affect the final cost ● cost plus contract - there is no guaranteed final cost for the job (often this contract is used where the project's nature prevents the final cost from being calculated). The consumer repays the builder for verified direct and indirect costs and fees at regular intervals. It is good practice for the builder to give a non-binding estimate before starting, and track costs with you against the project's budgeted estimate. Residential building work worth less than $20,000 must be done under a 'small jobs' contract. The written contract must be dated and signed by, or on behalf of, each party. It may specify that work be paid for at regular intervals. It must contain: ● the parties' names, including the name of the holder of the contractor licence as shown on the contractor licence ● the number of the contractor licence ● a description of the work ● any plans or specifications for the work, and ● the contract price, if known. Residential building contracts and contracts for specialist work valued at more than $5,000, which require a certifier, must (unless you are a developer) include terms about your freedom to choose your own certifier. The contractor must Attachment B DocuSign Envelope ID: BC2A1326-F575-4897-8DF1-275C49F872A0

July 2020 also give you prescribed information about certifiers, published by Fair Trading, before entering into a contract. It is an offence for a contractor to unduly influence your choice of a certifier or object to your choice. Examples of undue influence include:  making it a requirement of the contract that a specified certifier or class of certifier is or isn’t appointed  offering to change the contract price if a specified certifier or class of certifier is or isn’t appointed  refusing to carry out work under the contract if a specified certifier or class of certifier is or isn’t appointed. Residential building contracts regarding work worth more than $20,000 requires a full home building contract. As well as all of the requirements of the 'small jobs' contract, it must include other comprehensive information such as the details of the statutory warranties the builder must provide, the cost of any applicable HBC cover and the contract price or warning that the contract price is not known. The contract must also include a checklist prescribed by Fair Trading. Find a complete list of contract requirements on our website. All contracts over $20,000 in value must have a progress payment schedule. Progress payments must match the work carried out and, for cost plus contracts, be supported by receipts or other verifying documents. Any change you need to make to a contract is a ' variation '. Variations must be in writing and be signed by both parties to the contract. Almost all will impact the contract price. The maximum deposit you can be asked to pay before work starts is 10%. Common traps and tricks Beware of: ● an extremely low quote compared with others. This may indicate the job's quality is being compromised, or that the builder may not fully understand what is required ● `sales pitches´ putting pressure on you to sign a contract quickly to avoid a price increase ● a builder who recommends you get an owner-builder permit while they organise all the building work. The builder may be trying to avoid responsibility and may not have the right kind of licence or HBC cover. When things go wrong Statutory warranties Builders and tradespeople must guarantee that their work is fit-for-purpose, performed diligently and delivered in a reasonable timeframe, in line with the contract. Unless otherwise specified, materials should be new and appropriately used. These warranties are time-limited: legal proceedings to enforce them must be commenced within 6 years for major defects and 2 years for all other defects. There is another 6 months for both warranty periods if the defect only became apparent after 18 months or 5 and a half years. Find out more about these warranties on the Fair Trading website. Resolving a dispute with your builder or tradesperson These steps can help you resolve a dispute: ● you must notify your builder or tradesperson and discuss concerns as soon as you become aware of a problem. Follow up with an email or letter ● understand acceptable work standards by downloading the Guide to Standards and Tolerances from our website ● contact Fair Trading for free dispute resolution if you and your builder or tradesperson are unable to resolve the dispute ● lodge a claim with the NSW Civil and Administrative Tribunal (NCAT) if you remain unsatisfied with the dispute resolution outcome ● protect your rights under the HBC Scheme : contact your insurer or provider as soon as you become aware of defective or incomplete work. Home building compensation disputes For help resolving disputes with a HBC insurer or provider, visit the SIRA website sira.nsw.gov.au or call 13 10 50.

This requirement applies to a contract under which the licence holder undertakes: • to do, in person, or by others, any residential building work or any specialist work, or • to vary any such undertaking to do residential building work or any specialist work or the way in which any such work is to be done, but only if a registered certifier will be required with respect to some/all of the work.

A registered certifier is a public official, independent of the contractor Registered certifiers are public officials who do not work for builders, contractors, developers or property owners. A certifier can be from the private sector or your local council. A certifier’s role is to make an independent assessment to determine if relevant requirements of the Environmental Planning and Assessment Act 1979 have been met to warrant the issuing of a construction certificate, complying development certificate or occupation certificate. Certifiers do not supervise or manage builders, contractors or building sites. 1 None are currently prescribed by the Regulation.

Information about registered certifiers – Home Building Act 1989 – June 2020 What are a certifier’s responsibilities at each stage? Before construction starts, a certifier’s responsibilities include to: • check whether the proposed work will meet legislative requirements if built in accordance with the approved plans and specifications • advise which inspections will be mandatory as the work progresses • notify the council of their appointment as the principal certifier • check your builder or contractor is licensed and insured under the Home Building Act 1989 • check whether any applicable conditions of your consent or approval are met • check whether any applicable fees are paid, such as the long service levy • install a sign on the building site, showing the certifier’s details • inspect the building site (if required). During construction, a certifier’s responsibilities include to: • inspect the work in person, at each required stage • if a non-compliance is identified, issue a direction to you and/or the builder requiring certain action to be taken, and notify the council if the required action isn’t taken • respond appropriately to any complaints about the development, including informing the council if needed. After construction is finished, a certifier may issue an occupation certificate if: • all relevant conditions of your consent are met, and you have applied for the occupation certificate, and • all inspections have been carried out and the work is found to be satisfactory, unless an inspection (other than the final inspection) was missed under circumstances deemed unavoidable by the certifier (and evidence of suitability of the work is provided), and • the work is ‘suitable for occupation’ in accordance with the Building Code of Australia. Important: this is a minimum standard of compliance that must be met. It does not guarantee that all the work has been completed. For example, a house or apartment may be suitable for occupation while painting or landscaping is still being completed. An occupation certificate does not certify that the conditions of your contract with the builder have been met. The contract with your builder is a different contract to the contract with your certifier and must be considered separately. DocuSign Envelope ID: BC2A1326-F575-4897-8DF1-275C49F872A0

The choice and appointment of a certifier is yours – your builder may recommend a certifier but cannot appoint the certifier for you, cannot offer to change the contract price, and cannot refuse to carry out work if a particular certifier is not appointed. You must communicate with your builder, who will notify the certifier of each stage of work so the certifier can inspect it. If an inspection is missed, the certifier may have to refuse to issue an occupation certificate. You can request that the certifier and builder copy you into all correspondence between them.

Fair Trading Security of Payment Guide | February 2021 Security of Payment Guide Understanding progress payments in the building and construction industry The Security of Payment laws In NSW, people who carry out construction work or supply related goods and services under a construction contract are entitled to receive progress payments for the work or supply of those goods and services. This is regulated by the Building and Construction Industry Security of Payment Act 1999 (NSW) and Building and Construction Industry Security of Payment Regulation 2020 (NSW) (“Security of Payment laws”). The Security of Payment laws are relevant to those involved in contracts within the building and construction industry such as builders, tradies, subcontractors, consultants and suppliers. The purpose of the Security of Payment laws is to reduce the risk of insolvency in the building and construction industry in NSW by ensuring members of the contractual chain are paid for the work or services they provide. What do the Security of Payment laws apply to?  Any construction contract.  A construction contract that is written or oral.  A construction contract that is partly written and partly oral.  A construction contract that says it is to be governed by a law of a State or Territory outside of NSW but the work is carried out in NSW.  On and from 1 March 2021, owner occupier construction contracts. What are owner occupier construction contracts? Owner occupier construction contracts are construction contracts for residential building work on any premises or part of the premises where the contracting party resides or proposes to reside in. For example, an home owner engaging a builder to build their home. What’s not covered under Security of Payment laws? x A construction contract where the work is performed outside of NSW. x A construction contract for goods and services supplied in respect of construction work outside of NSW. x A construction contract that regulates an employer/employee relationship. x A construction contract that relates to a financial loan. What is a progress payment? A progress payment includes: • The final payment for construction work carried out or the supply of the goods/ services under the construction contract, or • A single or one-off payment for carrying out construction work or the supply of goods/ services under the construction contract, or • A payment based on an event or date (“milestone payment”). This does not prevent the building contractor making one payment claim for a progress payment in any particular month for construction work carried out or for related goods and services supplied in that month. How is a progress payment amount determined? The progress payment amount is usually set out in the construction contract. If the progress payment amount is not set out in the construction contract, the amount will be calculated based on the value of the construction work undertaken or the goods/service provided. When is a progress payment due for payment? A progress payment should be made in accordance with the terms of the applicable construction contract.

Fair Trading Security of Payment Guide | February 2021 Due date for payment A person entitled to a progress payment (the claimant) may serve a payment claim on the person who, under the construction contract concerned, is or may be liable to make the payment. There are specific maximum deadlines for payment depending on the nature of the contract. If the construction contract under which the payment claim is made is not an owner occupier construction contract as defined by the Act, the following will apply: Where a head contractor makes a payment claim to a principal, the payment claim becomes due and payable by the principal: • 15 business days after the payment claim is served on the principal, or • an earlier date if the construction contract between the principal and head contractor specifies this. A progress payment to be made to a subcontractor becomes due and payable: • 20 business days after the payment claim is served on the head contractor, or • an earlier date if the construction contract between the parties specifies this. Where a party to an owner occupier construction contract makes a payment claim, the claim becomes due and payable: • in accordance with the terms of the contract, or • if the contract makes no express provision with respect to the matter, on the date occurring 10 business days after a payment claim is served on the person liable to make the payment. Procedure for recovering progress payments  A claimant can serve one payment claim in any month under each contract (can be on last day of one month and first day of next month) or on or from an earlier date if the contract provides this.  If the construction contract has been terminated, a payment claim can be made from the date of termination.  A payment claim must identify the goods or services the claim relates to, the claimed amount, and clearly state it is a payment claim made under the Security of Payment laws.  A claimant can only make a claim within the period determined in the contract or 12 months after the work was carried out (whichever is later).  A head contractor claimant must fill out and attach a supporting statement form to their claim. Replying to a payment claim: payment schedules A party who has been served a payment claim (“the respondent”), may reply by providing a payment schedule to the claimant. There are strict timeframes for a respondent to provide a payment schedule to a claimant. These are: • within the time outlined in the construction contract, or • within 10 business days after the payment claim is served (whichever is earlier). If a respondent does not provide a payment schedule to the claimant within the timeframe required, they are liable to pay the amount requested by the claimant in the payment claim. A payment schedule must identify: • the payment claim it is for • the amount of payment (if any) that will be paid (the “scheduled amount”) • if the scheduled amount is less than the claimed amount, why the scheduled amount is less • if it is less because the respondent is withholding payment for any reason, the respondent’s reasons for withholding payment.

Important facts • Interest is payable on the unpaid amount of a progress payment that has become due and payable. • If a progress payment is due and payable, a claimant can exercise a legal right (called a lien) to legally possess any unfixed plant or materials they have supplied to the respondent, until the progress payment is paid. What if a progress payment is not paid? If the claimant has made a payment claim, and the respondent does not accept the payment claim, a claimant can apply to have the matter dealt with by an adjudicator or a court. A claimant can make a claim in court or make an application for the matter to be heard by an adjudicator, if: • the respondent does not provide a payment schedule, or • the scheduled amount indicated in the payment schedule is less than the claimed amount indicated in the payment claim, or • the respondent does not pay the claimant in accordance with the payment schedule. A claimant can serve a payment withholding request on a principal contractor to retain sufficient money to cover the claim out of money that is, or becomes payable by the principal contractor to the respondent. Adjudication A claimant may apply for adjudication of a payment claim where the respondent provides a payment schedule but: • the scheduled amount indicated in the payment schedule is less than the claimed amount, or • the respondent fails to pay the whole or any part of the scheduled amount to the claimant by the due date for payment of the amount. The claimant may also apply for adjudication of a payment claim if the respondent fails to provide a payment schedule at all to the claimant and also fails to pay the whole or any part of the claimed amount by the due date for payment of the amount. Information relating to the adjudication of payment claims is outlined in Division 2, Part 3 of the Act. Key points: Adjudication • The Security of Payment laws provide rules relating to an adjudication application, such as the number of days an application must be made within. For more details see section 17 of the Act. • A claimant may withdraw an adjudication application at any time before an adjudicator has been appointed or before the application is determined. • Authorised nominating authorities (organisations authorised by the Minister) refer adjudication applications to an eligible adjudicator. The eligibility criteria for adjudicators is detailed in clause 19 of the Regulation . Trust account requirements If a head contractor has a construction contract with a principal that has a value of at least $20 million , the head contractor has an obligation to:  Hold retention money in trust for the subcontractors entitled to the money.  Ensure that the money is paid into and retained in a trust account established with an authorised deposit-taking institution (ADI) approved under section 87 of the Property and Stock Agents Act 2002.  Ensure the retention money is paid into the trust account no later than 5 business days after the head contractor is required to retain the retention money. What is retention money? Retention money means money that is retained by a head contractor out of money that the head contractor is required to pay to a subcontractor under a construction contract as security for the performance of obligations of the subcontractor under the contract. For example, 5% of the contract’s value may be held as the retention money, or there could be an arrangement where there will be a 10% deduction from each of the subcontractor’s progress payments which is kept as the retention money component. Each construction contract may contain different terms and can be negotiated.

Establishing a trust account When establishing a trust account for retention money, there are certain requirements, such as notifying the Secretary of the account’s details and notifying the ADI that it is an account opened for the purposes of the Security of Payment laws. For more information on the requirements when opening a trust account see clause 9 of the Regulation. Withdrawals from a trust account A head contractor must not withdraw retention money from a retention money trust account except for 1 of these 4 reasons:  Payment of money in accordance with the terms of the construction contract under which the money was retained by the head contractor.  If the head contractor and subcontractor make an agreement in writing.  To pay an amount that an adjudicator has determined the respondent must pay to the claimant.  In accordance with an order of a court or tribunal. x It cannot be used by the head contractor to pay their own debts. Record keeping A head contractor must keep records in the form of a ledger to keep track of things such as the amounts deposited into or withdrawn from the account. The ledger is to be provided to the subcontractor at least once every 3 months, or as often as may be agreed in writing by the head contractor and the subcontractor (but at least once every 6 months).
