Building (Approvals and Practitioners) Bill 2026: What NSW's Biggest Regulatory Overhaul Means for Your Project

The NSW Parliament passed the Building (Approvals and Practitioners) Bill 2026 on 4 August 2026, marking the most significant overhaul of the state's building regulatory framework in a generation. The Bill replaces the fragmented certification regime under Part 6 of the Environmental Planning and Assessment Act 1979 with a modern, digitally integrated approvals system, consolidates practitioner registration under a single framework, and formally recognises prefabricated buildings in legislation for the first time in Australia. For homeowners, developers, builders, and certifiers across NSW, these reforms will fundamentally change how projects move from design through to completion.

What Is the Building (Approvals and Practitioners) Bill 2026?

The Building (Approvals and Practitioners) Bill 2026 is landmark NSW legislation that replaces the current construction certificate and occupation certificate regime with a new two-stage approval system: building approvals and completion approvals. Introduced to Parliament on 6 May 2026 by Minister Anoulack Chanthivong, the Bill passed both Houses on 4 August 2026 and is awaiting assent. It repeals the Design and Building Practitioners Act 2020, the Building and Development Certifiers Act 2018, and restructures Part 6 of the EP&A Act. The Government positions the Bill as a productivity reform that maintains building quality while streamlining approval pathways to help deliver the 377,000 new homes targeted by the National Housing Accord by July 2029.

How Does the New Approval System Replace Construction Certificates?

Under the Bill, the current construction certificate and occupation certificate requirements are removed from Part 6 of the EP&A Act and replaced with two new approval types. A building approval authorises building work to commence, replacing the construction certificate. A completion approval confirms that building work is finished and the building may be occupied, replacing the occupation certificate. A single approval authority — typically the local council or a registered practitioner — is nominated through the NSW Planning Portal for each project, creating a single point of accountability and a digital paper trail that future owners can access.

Critically, the Bill formalises staged building approvals for the first time. Developers can now seek early works approvals for excavation and piling while later design stages are still being resolved, potentially compressing project timelines by weeks or months. The approval authority can also consent to minor variations without requiring applicants to return to the original consent authority for a modified development consent — a longstanding industry pain point that has caused costly delays on countless NSW projects.

What Legislation Does the Bill Repeal and Replace?

The Bill consolidates three separate pieces of legislation into a single cohesive framework. The table below summarises what is being repealed and what replaces it:

Who Needs to Register Under the New Framework?

Part 4 of the Bill creates a single, consolidated registration framework for all practitioners performing "registered work" — including certifiers, professional engineers, and design and building practitioners. This replaces the fragmented registration arrangements that were previously spread across the DBP Act and the BDC Act. Registered work covers the issuing of approvals, carrying out of mandatory inspections, issuing of complying development certificates, subdivision works certificates, strata certificates, and swimming pool compliance certificates.

For builders and designers, this means a single registration pathway rather than multiple registrations under different Acts. For certifiers, the new framework strengthens independence provisions — conflict of interest penalties increase dramatically from $33,000 to $1.1 million, with automatic suspension upon conviction. The Bill also extends disciplinary powers to cover certifiers who have surrendered or allowed their registrations to lapse, closing a loophole that previously allowed certifiers facing misconduct proceedings to escape regulatory action by exiting the industry.

How Does the Bill Address Prefabricated and Modular Construction?

The Bill makes New South Wales the first Australian jurisdiction to formally define "prefabricated buildings" in legislation and integrate modern methods of construction (MMC) into the approvals system. A prefabricated building is defined as a substantially complete building or room, or a modular building component that becomes a building element when properly installed and cannot be inspected without destructive testing or opening once onsite. Manufacturers must provide a Prefabricated Building Declaration and Prefabricated Building Instructions to confirm compliance with the Building Code of Australia.

The Commonwealth Productivity Commission has estimated that MMC can reduce overall construction costs by up to 20% and deliver homes up to 50% faster. Provisions enabling the Crown to carry out prefabricated building work commence on assent, accelerating the delivery of social housing. However, the Bill also raises new liability questions — a single design flaw in a manufacturing-led model can propagate across multiple modules and potentially entire projects, concentrating risk in ways the insurance market is still adapting to.

What Are the Key Changes for Developers?

For developers, the Bill introduces both opportunities and new compliance obligations. The staged building approval system allows early works to proceed while later stages are finalised, potentially shaving weeks off project timelines. Minor variations can be approved by the approval authority without returning to the consent authority, reducing administrative friction. The Bill also introduces a formal post-commencement authorisation process to regularise unauthorised building work, providing a pathway to fix compliance issues that previously had no clear resolution.

However, developers must now ensure that applications for building approval include regulated designs and design compliance declarations from registered practitioners. For building work involving performance solutions, a report on the adequacy of the solution must accompany the application. The Bill also enhances enforcement mechanisms, including binding written directions backed by significantly increased penalties, meaning non-compliance carries greater financial risk than under the previous regime.

What Do Homeowners Need to Know?

For homeowners planning renovations or new builds, the Bill changes the approval pathway but not the fundamental requirement that building work must be properly authorised. A development consent alone does not authorise building work — a separate building approval is now required. The good news is that the digital-first system operating through the NSW Planning Portal should reduce double handling and create a single source of truth for all approval documentation, making it easier for homeowners to track their project's progress and for future buyers to understand how a building was approved and constructed.

The statutory duty of care established under the DBP Act is reproduced in Part 8 of the Bill, maintaining consumer protections. The long-stop limitation period for defective building work claims is re-established in Part 9. Homeowners should be aware that the Bill also amends the Residential Apartment Buildings (Compliance and Enforcement Powers) Act 2020 to introduce a new head of power for dispute resolution, which should help resolve building disputes without drawn-out and expensive legal proceedings.

What Should Builders and Certifiers Prepare For?

Builders and certifiers should begin preparing for the transition now, even though the bulk of the Bill will commence on a date to be proclaimed and regulations are expected to be developed through 2026–2027 with implementation anticipated from 2027. Key preparation steps include reviewing current registration status under the DBP Act and BDC Act, assessing how staged works and design documentation will be managed under the new regime, and identifying exposure to expanded compliance and enforcement powers.

The Bill introduces a new obligation on all persons to take reasonable steps to ensure building work complies with the Building Code of Australia. Certifiers face strengthened independence provisions modelled on the Independent Commission Against Corruption Act 1988 framework, with broader offence coverage. The increased penalties — up to $1.1 million for conflict of interest breaches — signal a significant shift in regulatory risk for practitioners who do not maintain strict compliance standards.

Comparison: Current System vs New Bill

What Is the Timeline for Implementation?

The Bill passed Parliament on 4 August 2026 and is awaiting assent. Provisions enabling the Crown to carry out prefabricated building work commence on assent, immediately accelerating social housing delivery. However, the bulk of the Bill will commence on a date to be proclaimed, with regulations expected to be developed through 2026–2027 and full implementation anticipated from 2027. The NSW Government has confirmed that key elements will not commence until the regulations are developed and approved, meaning the current certification regime remains in effect during the transition period.

For projects in the pipeline, developers should identify whether they will proceed under the current certification regime or the new approvals system. Contractual frameworks with consultants, builders, lenders, and insurers should be reviewed to ensure they can accommodate the new approval processes. Financing arrangements and sunset clauses predicated on the existing certification regime may need updating. Projects that could benefit from staged approvals should explore this pathway once the new framework is operational.

What Does This Mean for giantA Clients?

At giantA, we have been monitoring the Building (Approvals and Practitioners) Bill since its introduction in May 2026. Our team has analysed the Bill's provisions against our extensive experience delivering residential, dual occupancy, and multi-unit projects across NSW. For clients with current projects, the transition period means the existing certification process continues unchanged — there is no immediate change to how your project will be approved. For clients planning future projects, the new staged approval system offers potential timeline savings, particularly for complex developments where early works can proceed while design details are finalised.

Our experience coordinating 12-unit townhouse developments in Merrylands — where agency coordination was compressed from 14 weeks to 5 weeks through proactive engagement — demonstrates the value of early planning under regulatory transitions. We recommend clients with projects in the design phase begin aligning documentation with the new Bill's requirements, particularly the design compliance declaration framework, to ensure a smooth transition when the new regime commences. Contact our team for a project-specific assessment of how the Bill may affect your development timeline and compliance obligations.

Frequently Asked Questions

When does the Building (Approvals and Practitioners) Bill 2026 take effect?

The Bill passed NSW Parliament on 4 August 2026 and is awaiting assent. Crown prefabricated building work provisions commence on assent immediately. The bulk of the Bill commences on a date to be proclaimed, with regulations expected through 2026–2027 and full implementation anticipated from 2027. The current certification regime remains in effect during the transition period.

Does the Bill replace construction certificates and occupation certificates?

Yes. The Bill removes construction certificate and occupation certificate requirements from Part 6 of the EP&A Act and replaces them with building approvals (authorising building work) and completion approvals (confirming work is finished and the building may be occupied). A single approval authority is nominated through the NSW Planning Portal for each project.

Will I need a new registration if I am already registered under the DBP Act?

The Bill creates a single consolidated registration framework replacing the fragmented arrangements under the DBP Act and BDC Act. Existing registrants will transition to the new framework, though specific transition arrangements will be set out in the regulations. Practitioners should monitor the release of draft regulations and ensure their registration remains current during the transition.

How does the Bill affect prefabricated and modular buildings?

The Bill formally defines prefabricated buildings in legislation for the first time in Australia, integrates modern methods of construction into the approvals system, and requires manufacturers to provide a Prefabricated Building Declaration and installation instructions. This brings modular construction under the same regulatory framework as traditional buildings, ensuring consumer protections apply equally. The Commonwealth Productivity Commission estimates MMC can reduce construction costs by up to 20% and deliver homes up to 50% faster.

What are the new penalties for certifier conflict of interest?

Maximum court-imposed penalties for certifier conflict of interest breaches increase from $33,000 to $1.1 million under the Bill, with automatic suspension upon conviction. The Bill also extends disciplinary powers to cover certifiers who have surrendered or allowed their registrations to lapse, closing a loophole that previously allowed certifiers facing misconduct proceedings to escape regulatory action by exiting the industry.

Can I still use the current approval system for my project?

Yes, during the transition period the current certification regime under Part 6 of the EP&A Act remains in effect. The NSW Government has confirmed that key elements of the Bill will not commence until supporting regulations are developed and approved. Projects with existing development consents should continue under the current system unless they choose to opt into the new framework once it is operational.

Does the Bill change the statutory duty of care for builders?

No. Part 8 of the Bill reproduces the statutory duty of care established under the DBP Act. The NSW Government has expressly stated that the Bill "seeks to uphold the existing operation, application and interpretation of the duty" and that "now is not the right time to overhaul our established duty of care system for construction." The long-stop limitation period for defective building work claims is re-established in Part 9.

How does staged building approval work under the new Bill?

The Bill formalises staged building approvals, allowing early works approvals for activities like excavation and piling to proceed while later design stages are resolved. A separate application must be made for each stage, and the approval for the first stage must include a staging schedule. The approval authority must consider the impact of each stage on subsequent stages. This can potentially compress project timelines by enabling parallel work streams.
