The NCC is a performance-based code published by the Australian Building
Codes Board (ABCB) and adopted by all state and territory governments.
It is updated on a regular cycle — the current 2022 edition has been
adopted in Victoria. The NCC has three volumes: Volume 1 covers
commercial buildings (Classes 2–9), Volume 2 covers residential
buildings (Class 1 and 10), and Volume 3 covers plumbing and drainage.
Key NCC Requirements for Victorian Buildings
Structural Provisions
All buildings must be structurally adequate to withstand dead loads
(self-weight), live loads (occupants and contents), wind loads (based on
local wind region), earthquake loads (Victoria is in a low-to-moderate
seismicity zone), and snow loads (applicable to alpine areas).
Structural design must comply with Australian Standards referenced in
the NCC.
Fire Safety
NCC fire safety provisions govern fire compartmentalisation (limiting
the spread of fire between sections of a building), exit provisions
(width, number, and location of emergency exits), fire detection and
suppression systems (smoke alarms, sprinklers), construction materials
(fire resistance levels of structural elements), and emergency lighting.
Requirements escalate significantly with building height and class.
Energy Efficiency
As of NCC 2022, all new Class 1 (residential) buildings must achieve a
minimum 7-Star NatHERS rating — up from 6 stars previously. This is
one of the most significant compliance changes in recent years. Class
2–9 buildings must comply with Section J energy efficiency provisions,
which have also been strengthened. All new dwellings must also have
on-site renewable energy generation capacity (solar panels).
Accessibility
Class 2 apartment buildings must comply with Livable Housing Design
requirements under NCC 2022. Commercial buildings must meet
accessibility provisions in accordance with the Disability
Discrimination Act 1992 and NCC Part D3. These requirements affect floor
grading, door widths, lift provisions, accessible parking, and bathroom
design.
How Integral Design Solutions Ensures NCC Compliance
Our peer review service includes systematic assessment of building
designs and documentation against all applicable NCC provisions. We use
structured compliance checklists and have deep experience with the most
complex NCC requirements — fire safety, energy efficiency, and
accessibility. Our peer review reports provide clear, actionable
findings that allow design teams to resolve issues efficiently.
Frequently Asked Questions
Do existing buildings need to comply with the 2022 NCC?
Existing buildings are generally assessed against the code in force at
the time they were built. However, if you carry out alteration or
extension work, the new work must comply with the current NCC.
Significant alterations may also trigger requirements to upgrade
existing non-compliant elements.
What happens if a building doesn’t comply with the NCC?
Building work that does not comply with the NCC will not receive a
building permit (or will not pass mandatory inspections). If
non-compliance is discovered during construction, work may need to be
demolished and rebuilt. Post-construction non-compliance can trigger a
building order requiring rectification at the owner’s cost.
Who is responsible for NCC compliance?
Primary responsibility sits with the registered building practitioner
(builder) and the building surveyor who issues the permit and inspects
the work. The architect and engineer are responsible for their
respective design disciplines. The building owner has overall
responsibility for ensuring approved practitioners are engaged.
