Becoming an Owner-builder in NSW

Being an owner-builder means managing your construction project from start to finish. This includes deciding on materials, hiring tradesmen, and overseeing day-to-day operations. Owner-builder work involves any construction, alteration, repair, or addition to a property where the market cost exceeds $10,000. This role offers hands-on experience, financial control, customization, and valuable learning opportunities. However, it also requires significant time, effort, and meticulous planning. Wondering if becoming an owner-builder the right decision for you? Read our detailed article here to find out.

The key obligations of owner-builders in NSW can be categorised as follows:

Work Health and Safety Act 2011

The Act regulates work and safety through a combination of legislation, regulations, codes of practice, and other guidance materials. It imposes duties on various parties involved in a business or undertaking, including PCBUs, workers, self-employed persons, manufacturers, designers, importers, and suppliers.

Home Building Act 1989

The provisions of this Act cover aspects like warranty insurance and building standards. Complying with the mandates of this Act are necessary for any residential construction in NSW.

Insurance Requirements

This involves securing the mandatory types of insurance for your residential construction, such as public liability insurance, workers’ compensation insurance, home warranty insurance and contact works insurance. Having these insurance coverages can be critical in protecting your financial interests.

Under the Work Health and Safety Act 2011, owner-builders have significant legal responsibilities, particularly when managing contractors like plumbers or electricians. These duties generally align with those of a person conducting a business or undertaking (PCBU) and include managing or controlling the workplace and consulting with other duty holders.

As a PCBU, an owner-builder must ensure the health and safety of workers and others affected by the work, as far as reasonably practicable. This includes:

  • Providing and maintaining a safe working environment.
  • Ensuring safe operation and maintenance of plant and structures.
  • Providing safe systems of work.
  • Ensuring the safe handling, storage, and transport of materials.
  • Providing adequate facilities and information for workers.
  • Monitoring health conditions and workplace conditions to prevent work-related injuries and illnesses.

Principal Contractor Duties

If acting as a principal contractor, the owner-builder has additional responsibilities such as:

  • Posting signage that identifies them as the principal contractor.
  • Preparing and updating the work health and safety management plan.
  • Ensuring compliance with the health and safety plan and regulatory requirements.
  • Managing risks associated with construction materials, waste, plant, and traffic.
  • Ensuring all high-risk construction work does not commence until a safe work method statement is in place.

Consultation, Compliance and Training Requirements

The Act mandates that PCBUs must consult with workers and other duty holders on health and safety matters, especially when changes affecting health and safety are proposed.

Owner-builders should complete general construction training courses to understand the risks associated with building projects. They should also ensure that all workers and contractors have completed necessary general induction training before commencing work.

Obligations of Owner-builder to Obtain Approvals for Building Work

Owner-builders Permit

An owner-builder permit is essential for anyone who plans to personally supervise or engage in construction work on their own home where the project’s market value (including labour and materials) exceeds $10,000. This permit is especially necessary for work that involves significant alterations, repairs, or additions to a single dwelling-house, a dual occupancy, or a secondary dwelling. The permit is mandatory for projects requiring development consent under Part 4 of the Environmental Planning and Assessment Act 1979 or those classified as a complying development.

To qualify for an owner-builder permit, applicants must:

  • Be at least 18 years old.
  • Own the land outright, share ownership, be a shareholder in a company that owns the land, or hold a registered lease for more than three years on the land.
  • Intend to reside in the dwelling upon completion of the construction.
  • Not have commenced the building work prior to the application.
  • Ensure the property is not part of a multi-dwelling strata complex.
  • Have not received an owner-builder permit on any other property within the last five years unless it pertains to the same land or special circumstances are demonstrated.
  • Meet educational requirements for projects valued at $20,000 or more by completing approved units of competency or possessing equivalent qualifications and experience.

Application Process for an Owner-Builder Permit

Applicants must prepare several documents and information before applying:

  • A valid MyServiceNSW account.
  • Proof of identity.
  • Proof of land ownership or a long-term lease agreement.
  • Details and estimated cost of the construction work.
  • A copy of the approved development consent (Development Approval or Complying Development Certificate).
  • A current white card indicating completion of general construction induction training.
  • Evidence of completed owner-builder education requirements for work over $20,000.
  • Payment for the applicable license fee.

Applications can be submitted online via the Service NSW website, where all co-owners of the land must be listed. Each owner is restricted from applying for another owner-builder permit on different land for five years.

In instances where an owner-builder permit is required for dual occupancy constructions or if an owner has held a permit in the last five years, additional details must be provided. Applicants may need to complete an extra form outlining these special circumstances as part of their application.

Providing false or misleading information in an owner-builder permit application is a serious offense under the Crimes Act 1900, with penalties including imprisonment for up to two years, a fine of up to $22,000, or both. Additionally, the Fair Trading Commissioner has the authority to cancel a permit if misinformation is discovered post-issuance.

This permit system underscores the importance of regulatory compliance in construction, ensuring that owner-builders are adequately prepared and qualified to manage building projects on their properties effectively.

The first step in gaining approval for building work is to obtain either a development consent or a Complying Development Certificate (CDC). Development consent can come in the form of a Development Application (DA) approved by the local council or a CDC, which may be issued by either a private accredited certifier or the council. A CDC facilitates a faster approval process for straightforward developments that meet specific criteria set out in legislation.

It’s important to note that obtaining an owner-builder permit is not required to apply for development consent. However, an owner-builder permit must be acquired before appointing a Principal Certifying Authority and commencing any building work.

Construction Approval for Building Work

After securing development consent, the next step is to obtain a construction certificate. This certificate confirms that the detailed construction plans and specifications comply with the Building Code of Australia and any applicable council codes. Either the local council or a private accredited certifier can issue this certificate. Throughout the construction phase, the building work may need to be inspected by the certifying authority to ensure it adheres to national building standards.

Using Licensed Tradespeople

For specific trades, particularly those involving safety risks such as electrical work, plumbing, and air-conditioning, only licensed professionals may undertake the job. This requirement applies regardless of the cost of the work:

  • Electrical wiring
  • Plumbing, draining, and gasfitting
  • Air-conditioning and refrigeration work (excluding plug-in appliances)

Owner-builders must ensure that all tradespeople engaged for these tasks hold the appropriate Fair Trading licence. Before contracting any tradesperson, it’s crucial to verify their licence through Fair Trading’s online licence check or by phone.

Contracts for Owner-Builders

Any construction, renovation, or maintenance work exceeding $5,000 in total contract price or where the combined labour and materials provided by the contractor exceed $5,000 requires a written contract. This contract should clearly outline all terms, including scope of work, payment schedules, and any warranties.

Failure to comply with these regulations can result in significant fines up to $22,000. Ensuring that all these steps are followed can protect owner-builders from potential legal issues and help maintain the integrity and safety of the construction project.

Owner-builder’s Obligation to Get Appropriate Insurance

When embarking on a building project as an owner-builder, it’s essential to understand the various types of insurance that can protect you, your property, and other individuals involved in the project. Here’s a breakdown of the key insurance types you should be aware of:

Compulsory Home Building Compensation Cover

Although home building compensation cover is not available for work done directly by an owner-builder, any licensed contractor, whether a builder or tradesperson, must provide this cover when the contract price exceeds $20,000. This includes materials supplied by the contractor. As an owner-builder, you should ensure you receive a copy of the certificate of insurance before work commences and before any payment is made. For detailed information or to check coverage, visit the State Insurance Regulatory Authority website or use the HBC Check.

Workers Compensation Insurance

As an owner-builder, determining the need for workers’ compensation insurance is crucial when hiring contractors. Depending on the specific arrangements, contractors may be classified as ‘workers’. This insurance protects against the costs associated with injuries that workers may sustain during the project. For more advice on workers compensation insurance, contact icare or call their helpline.

Contract Works Insurance

Builders and trade contractors engaged in your project should carry contract works insurance. This insurance is vital as it covers the loss or damage to materials and works in progress. If a builder or contractor lacks this insurance, you might face delays, added costs, and disputes should materials get damaged or stolen during the construction phase.

Public Liability Insurance

Taking out public liability insurance is highly recommended for anyone planning to act as an owner-builder or contract any building work. This insurance is crucial as it covers you if a family member, worker, or member of the public gets injured as a result of the building work. Given that accidents can happen on construction sites, public liability insurance provides financial protection against claims, safeguarding your financial stability.

Overall, securing the right insurance coverages as an owner-builder not only complies with legal requirements but also provides peace of mind throughout the construction process, ensuring you are adequately protected against a range of potential risks.

Responsibilities of an Owner-builder at the Time of Sale

Consumer Warning

When an owner-builder decides to sell their property within 7 years and 6 months of the issue date of their owner-builder permit, they are required to inform potential buyers of this status. This is done through a consumer warning included in the contract for sale. The warning must explicitly state that the property was constructed or significantly renovated under an owner-builder permit, specifying the date it was issued. This disclosure is crucial as it informs the buyer of the potential risks and responsibilities associated with owner-built properties. Neglecting to include this warning in the contract allows the buyer to legally void the contract prior to settlement, protecting the buyer from undisclosed risks associated with owner-built homes.

Statutory Warranties

Under the Home Building Act 1989, statutory warranties are provided to safeguard the interests of subsequent homeowners. These warranties are legally binding for a period of up to 7 years after the completion of the building work. They ensure that all construction work is carried out:

  • With due care and skill and in a professional manner.
  • In accordance with the plans and specifications set out in the contract.
  • In compliance with all relevant laws and legal requirements.
  • Within the timeframe stipulated in the contract, or if no time is specified, then within a reasonable timeframe.

Furthermore, the materials used in the construction must be:

  • Fit for the specified purpose and yield the results that the homeowner desires, as stipulated in the contract.
  • New and of suitable quality unless otherwise specified in the contract.

If the owner-builder fails to meet these warranties, the new owner has the right to enforce these warranties against them. This enforcement could be pursued through the NSW Civil and Administrative Tribunal, which can hold the owner-builder accountable for rectifying defects, completing unfinished work, or providing financial compensation for losses incurred due to substandard or incomplete work. This framework is designed to ensure that the property meets expected safety and quality standards, providing peace of mind and legal recourse for the new owner.

Case Study – Owner Builder Permit Not Required for Benefit of Statutory Warranties

Recently, the Supreme Court of NSW affirmed that individuals who undertake owner-builder work without obtaining the requisite permit under the Home Building Act 1989 (NSW) (‘HB Act’) are still subject to statutory warranties provided in section 18B of the HB Act. This ruling highlights the legislative intent to protect consumers regardless of procedural compliance by owner-builders.

The case, McIntosh v Lennon [2024] NSWSC 169, arose from an appeal against the decision of the Appeal Panel of the NSW Civil and Administrative Tribunal. The tribunal had expanded the definition of “owner-builder” under the HB Act to include those who had not obtained an owner-builder permit, a decision the plaintiffs challenged.

Supreme Court’s Decision

The Supreme Court’s analysis centred on the purposive approach to statutory interpretation. The court examined the intent of the HB Act, which aims to ensure that all residential building works carry statutory warranties to protect homeowners. It determined that excluding individuals who failed to obtain an owner-builder permit from the definition of owner-builder would undermine this protective mechanism.

Key points from the court’s reasoning include:

  • Purpose of the Act: The court found that the HB Act was designed to remedy specific mischiefs in the building industry, specifically the risk to consumers from non-compliant building works.
  • Legislative Oversight: It was apparent to the court that the legislature inadvertently omitted to cover the scenario where an owner-builder fails to obtain a permit. This oversight, if unaddressed, would leave a gap in consumer protections.
  • Reading in Words: The court was convinced that it was appropriate to read in the words “or is required to do” into the definition of owner-builder to align with the legislative purpose of the HB Act. This interpretation ensures that all residential building works, regardless of permit status, are subject to statutory warranties.

Implications of the Decision

This decision underscores the broad protective scope of the HB Act, ensuring that homeowners are safeguarded against defective building works irrespective of the formal compliance of the builder. It sends a clear message that statutory protections cannot be circumvented through technicalities in compliance.

The ruling also clarifies that the term “owner-builder” encompasses not only those who have formally obtained permits but also those who undertake substantial building work without the necessary legal permissions, thus extending consumer protections to a broader group of homeowners.

This decision serves as a critical reminder of the importance of statutory warranties in the home building sector. It reinforces the principle that legislative protections for homeowners should not be negated by procedural non-compliance by builders, ensuring that all parties engaging in significant building works are accountable under the HB Act. This ruling not only protects consumers but also helps maintain high standards within the residential building industry.

Navigating the responsibilities of an owner-builder in NSW involves a comprehensive understanding of several legal requirements, from adhering to safety regulations to ensuring proper insurance and compliance with building standards. By fulfilling these obligations, owner-builders not only protect themselves from potential legal issues but also contribute to the integrity and safety of the building industry.
