What is this right?
The National Construction Code (NCC) sets the minimum technical standards every residential building in Australia must meet. It is developed by the Australian Building Codes Board (ABCB) — a joint federal-state body — and adopted into state and territory legislation.
For homes, the NCC covers structural safety, fire resistance, waterproofing, energy efficiency, accessibility, and ventilation. Since 1 October 2023, all new homes must meet a minimum 7-star NatHERS energy rating (up from 6 stars), meaning better insulation, glazing, and energy performance.
Under the Livable Housing Design Standard (NCC 2022), new homes must also include basic accessibility features — such as a step-free entry, wider doorways (minimum 820 mm clear opening), and a toilet on the entry level. These requirements apply to Class 1a houses and Class 2 apartments.
If your new home does not meet NCC standards, the builder is responsible for rectifying the defects. Each state has a statutory warranty period — typically 6 years for structural defects and 2 years for non-structural defects.
When does it apply?
- You are building a new home or undertaking major renovations that require a building permit.
- You are buying a newly built home — the builder must certify NCC compliance before issuing an occupancy certificate.
- You are an apartment buyer in a new Class 2 building subject to accessibility and energy requirements.
- You are lodging a building defects claim within the statutory warranty period.
What to Do If Your New Australian Home Doesn't Meet Building Code Standards
- Request a copy of the occupancy certificate and building compliance certificate before settling on a new home.
- Hire an independent building inspector to check NCC compliance before settlement — this typically costs $400–$800.
- Report defects in writing to your builder as soon as you discover them, and keep dated photos and correspondence.
- Check the energy rating — the 7-star NatHERS requirement applies to building approvals lodged from 1 October 2023 onward.
What should you NOT do?
- Don't assume all homes meet the latest NCC version — standards that apply depend on the date of building approval, not the date of sale.
- Don't ignore minor defects — small issues may indicate larger non-compliance problems and should be reported within the warranty window.
- Don't rely solely on council inspections — council certifiers check key stages but do not guarantee full compliance.
- Don't confuse the NCC with state-specific rules — states may add extra requirements on top of the NCC minimum.
How Tasmania differs from federal law
Building standards in Tasmania are regulated under the Building Act 2016 (Tas), which implements the National Construction Code (NCC) through the state's building regulatory framework.
- The NCC is adopted in Tasmania through the Building Act 2016 and the Building Regulations 2016 (Tas). All new buildings and major renovations must comply with the NCC's minimum standards for structural safety, fire safety, accessibility, energy efficiency, and plumbing.
- Building work in Tasmania requires a building permit from a permit authority (usually the relevant council) or a private building surveyor accredited under the Building Act.
- Consumer, Building and Occupational Services (CBOS), within the Department of Justice, is the state regulator for building practitioners, including builders, plumbers, gas fitters, and electricians.
- CBOS administers the building practitioner licensing system and investigates complaints about building work and building practitioners.
- Tasmania's building regulations account for the state's unique climate (cooler and wetter than mainland states), with energy efficiency provisions reflecting local conditions.
Additional Steps in Tasmania
Check building requirements through your local council or CBOS (cbos.tas.gov.au). Lodge complaints about building defects or unlicensed building work with CBOS. For disputes about building work, the Magistrates Court (Civil Division) may have jurisdiction.
