Understanding Home Building Contracts

A home building contract is a legally binding agreement between the homeowner and the builder that outlines the terms and conditions of the building project. The contract must be in writing and signed by both parties to be enforceable.

In NSW, there are two types of home building contracts: fixed-price contracts and cost-plus contracts. Fixed-price contracts have a set price that the builder will charge for the entire project. In contrast, cost-plus contracts involve the builder charging the homeowner for the cost of the materials and labour, plus an additional percentage for profit.

Key provisions of a home building contract include the scope of work, progress payments, timeframe for completion, and dispute resolution procedures. It is essential to carefully review and understand these provisions before signing the contract.


In NSW, home building contracts are governed by the Home Building Act 1989 (NSW) and must comply with legal requirements such as providing a cooling-off period, obtaining home warranty insurance, and including mandatory notices. Homeowners are encouraged to seek legal advice to ensure their rights and obligations are protected.

Common Causes of Breach of Contract in Home Building Contracts

Home building contracts are legally binding agreements between the homeowner and the builder. When either party fails to fulfil their contractual obligations, a breach of contract occurs. Here are the most common causes of breach of contract in home building contracts in NSW:

  1. Delays in completion of the project
    Builders are required to complete the construction project within the agreed-upon timeframe. If the builder delays the completion of the project, it could be considered a breach of contract.
  2. Quality of work
    Builders are required to complete the construction work in a workmanlike manner and in accordance with the agreed-upon specifications. If the builder fails to meet the required standards of quality, it could be considered a breach of contract.
  3. Payment disputes
    Disputes over payments are common in home building contracts. If the builder demands payment before completing the work or the homeowner refuses to pay for work that has been completed, it could be considered a breach of contract.
  4. Changes to the scope of work
    Changes to the scope of work can lead to disputes between the homeowner and builder. If the builder does not comply with the agreed-upon changes, it could be considered a breach of contract.Failure to comply with building standards
    Builders are required to comply with building standards and regulations. If the builder fails to meet the required standards, it could be considered a breach of contract.
  5. Failure to obtain necessary approvals and permits
    Builders are required to obtain the necessary approvals and permits before starting construction. If the builder fails to obtain the necessary approvals or permits, it could be considered a breach of contract.

It is important to note that breaches of contract can have serious consequences, including legal action and financial penalties. Homeowners and builders should seek legal advice if they suspect a breach of contract has occurred.

Remedies for Breach of Contract in Home Building Contracts

In the event of a breach of contract in a home building contract in NSW, there are several remedies available to the parties involved. These remedies aim to put the non-breaching party in the position they would have been in if the contract had been fulfilled. The following are common remedies for breach of contract in home building contracts:

  • Issuance of Notice of Breach: The innocent party may issue a notice of breach to the breaching party, stating the details of the breach and providing the breaching party a reasonable time to remedy the breach.
  • Termination of the contract: The innocent party may terminate the contract by issuing a notice of termination, if the breaching party fails to remedy the breach within the reasonable time provided in the notice of breach.
  • Damages and compensation: The innocent party may be entitled to damages or compensation for any loss or damage suffered as a result of the breach. The amount of damages will depend on the nature and extent of the breach and the loss suffered.
  • Specific performance: If the breach involves a failure to complete the work, the innocent party may seek a court order for specific performance, which requires the breaching party to complete the work as per the contract.
  • Rectification: If the breach involves defective or incomplete work, the innocent party may seek a court order for rectification, which requires the breaching party to correct the defective or incomplete work.

It is essential to seek legal advice before pursuing any remedy for breach of contract in a home building contract to ensure that the remedy pursued is appropriate for the particular circumstances of the case.

Resolving Disputes

Resolving disputes early is crucial in home building contracts in NSW to avoid further damage, delay, and expenses. If a dispute arises, parties should attempt to resolve the issue through negotiation, mediation, or arbitration. These methods provide an opportunity for parties to discuss the issue and come up with a mutually beneficial solution.

If these methods fail, legal action may be necessary. In NSW, the NSW Civil and Administrative Tribunal (NCAT) handles disputes related to home building contracts. Parties may also choose to pursue legal action through the court system.

It is essential to seek legal advice before pursuing legal action, as it can be expensive and time-consuming. A legal professional can provide guidance on the best course of action and the likelihood of success.
