The National Construction Code 2025 has set out the next major update to Australia’s building regulations, with significant new rules for commercial properties.
Developed by the Australian Building Codes Board (ABCB), the latest National Construction Code (NCC) was published 1 February, with adoption slated from May 2026, although some States and territories may choose their own adoption timelines.
The NCC sets the design and construction minimum standards for buildings across the country, and NCC 2025 introduces important updates focused on the areas of energy generation and efficiency, waterproofing, fire and safety measures.
The Code advances Australia toward higher-quality buildings that are both safer and greener, and as part of this commercial premises must meet higher performance benchmarks.
Understanding the requirements can help operators better prepare for how the new rules might affect a project, but ultimately each new hoop to traverse is another potential roadblock.
“It is getting harder and harder to achieve compliance with renovations and new builds,” says veteran hospitality designer Paul Kelly, principal of PKD.
“The rise in regulation just increases the costs for the operator and slows down development. Unfortunately, these changes make it more difficult without any benefit to the customer.”
Key Changes in NCC 2025
There are several new mandates, which will affect new commercial and multi-residential structures.
Solar Panel Mandate for commercial buildings: new construction must install on-site solar PV systems covering usable roof space or meeting a minimum system size, which is expected to lower long-term energy costs.
Energy Efficiency Enhancements: larger buildings will experience tighter standards for insulation and HVAC systems.
Waterproofing and water management: improvements to waterproofing, balconies and facades to reduce moisture damage, with better drainage design and detailing. Condensation risk control mandates vapour-permeable membranes, ventilation and escape pathways – aiming to reduce health risks from mould.
Carpark and fire safety upgrades dictate better fire protection in enclosed carparks, with photoluminescent exit signs and safer re-entry into fire-isolated stairwells, while Improved Access and Amenities addresses gender equity in bathroom facilities, requiring a higher ratio of female toilets.
Putting it in Practice
Navigation of the new NCC will require stakeholders make decisions earlier in the process, and more than ever, keep an accurate documentation trail.
PKD notes that elements of the Code, such as the location of plant and services amongst the required solar panels, and the strategic approach to façades, will inevitably result in the need for more consultants and inspections and certification, to abide by conditions and prevent future defects.
“The higher standards will save the purchaser of a venue money,” adds Kelly, while boding that the strict rules can regularly influence the timeline of a project.
“The NCC matters, because without adhering to it you simply cannot open your venue!”
Major changes to regulations in the housing sector have been paused until 2029, reportedly to ease pressure on the industry and support affordability in new dwellings.
