NSW Unveils Landmark Building Reforms to Fast-Track Housing and Embrace Prefab Homes

The Minns Labor Government will introduce sweeping building reforms to Parliament aimed at accelerating housing delivery, modernising approvals, and strengthening oversight across the construction sector.

The proposed Building (Approvals and Practitioners) Bill 2026 is designed to support faster construction of safe, high-quality homes while making it easier and less costly to resolve building disputes without immediately resorting to court action.

A key feature of the reforms is a strong push to expand the use of Modern Methods of Construction (MMC), including modular and prefabricated housing. According to the Commonwealth Productivity Commission, these methods can cut construction costs by up to 20 per cent and reduce build times by as much as half.

If passed, the legislation would make NSW the first state in Australia to formally recognise prefabricated buildings in law, integrate MMC into the approvals process, and embed consumer protections for these construction methods. The changes are intended to build confidence among both industry and homeowners, positioning MMC as a mainstream housing option.

The Bill also seeks to overhaul the building approvals system by consolidating multiple legislative processes into a single framework. This would eliminate duplication, reduce costs, and improve efficiency. For example, removing the need for repeated design work could save around $330,000 per apartment block.

Other measures include introducing staged approvals to allow construction and occupancy to begin sooner, enabling minor design changes to be approved more easily, and establishing a streamlined digital system to manage approvals. The reforms aim to create a single, reliable source of information for consumers, regulators, and industry professionals.

To strengthen accountability, the Bill introduces tougher rules for certifiers, including clearer conflict-of-interest provisions. Maximum penalties for breaches would rise significantly-from $33,000 to $1.1 million-with automatic suspension for those convicted of violations.

Planning Minister Paul Scully said the reforms would simplify a fragmented system and improve outcomes across the housing pipeline. Housing Minister Rose Jackson said the changes would remove barriers to modern construction methods while maintaining quality standards. Building Minister Anoulack Chanthivong said cutting red tape would help increase housing supply and support innovation in the sector.

NSW Building Commissioner James Sherrard said the reforms would provide stronger oversight and improve confidence in emerging construction methods. Master Builders NSW Executive Director Matt Pollock welcomed the changes, saying they strike a balance between improving consumer protections and speeding up approvals to deliver more homes.
