Short answer: A building is non-compliant when its design, construction, alteration or use does not meet the requirements that legally apply to that project. In Australia, the starting point is the National Construction Code (NCC), but the correct edition, state or territory adoption, building use, approval conditions and commencement dates must be established first. A non-compliance finding does not automatically mean a particular penalty or danger; the response can range from documentary correction to physical rectification, and depends on the authority and the issue.

The problem of non-compliance is identified by Architecture & Design as an Architecture & Design Team resource dated 13 March 2023 and associated with Wintec Systems. Its landing page exposes a download control but not the document text, so its specific examples, evidence and recommendations cannot be treated as verified here. The practical guide below explains how to establish compliance without attributing claims the accessible page does not make.
What building-code non-compliance means in practice
“Non-compliant” is a conclusion about a defined requirement, not a synonym for “poor quality” or “unsafe.” The relevant question is: which rule applies to this building, what evidence shows the required outcome, and where does the built work differ?
#1 Best Overall
The NCC requirement
The Australian Building Codes Board (ABCB) describes the NCC as Australia’s primary technical design and construction code for buildings. It is performance-based and sets minimum required levels in areas including safety, health, amenity, accessibility and sustainability for the buildings within its scope. A project can therefore fail in a number of different ways: an outcome may not be achieved, a required process may not have been followed, or the available evidence may be insufficient to demonstrate compliance.
Approval and occupancy conditions
Planning approvals, building permits, fire-safety conditions, heritage controls and directions from a certifier or building surveyor can impose obligations in addition to the general NCC text. Those conditions are project-specific. A feature that is acceptable in one approval may not be acceptable in another, even when the buildings appear similar.

Contract and installation obligations
Specifications, drawings, schedules and manufacturer instructions can require a particular system or installation method. Meeting a product specification does not, by itself, prove that the complete building complies. Conversely, a variation may be acceptable if a competent authority approves an alternative and the required performance is demonstrated.
Why the edition and jurisdiction must be identified first
Australia does not apply one timeless, nationally identical rule book to every project. State and territory governments adopt and administer the NCC, and commencement, transitional provisions and local variations can affect the obligation that applies. Establish these facts before checking a detail such as a doorway, window, wet-area finish or fire-related lining.
| Question to answer | Why it changes the compliance check | Useful record |
|---|---|---|
| Where is the project? | The state or territory determines adoption, variations and the responsible regulator or certifier. | Site address, jurisdiction and approval authority |
| What is the building’s use and classification? | Performance expectations differ according to the building’s purpose, occupants and risk profile. | Approved plans, classification and occupancy description |
| When was the work approved and commenced? | Transition rules and commencement dates can determine which edition or amendment governs. | Permit, approval and commencement dates |
| Which NCC edition and amendments were adopted? | A clause, definition or referenced standard can change between editions. | Written confirmation from the project certifier or authority |
| Was an alternative solution approved? | A Performance Solution may rely on a documented analysis rather than a Deemed-to-Satisfy detail. | Performance Solution report, calculations and approval |
The ABCB page identifies NCC 2022 Amendment 2 as being read with Amendment 1 from 29 July 2025, and notes that Amendment 2 aligns the NCC with recent amendments to the Disability (Access to Premises—Buildings) Standards 2010. The same page offers an NCC 2025 preview draft. Those statements do not establish which edition applies to your project. Confirm local adoption and the relevant commencement date instead of treating a preview or a national publication date as a project approval.

How to check whether a building complies with the NCC
Use a documented sequence. A visual walk-through alone cannot establish compliance, because many requirements concern design assumptions, hidden construction, calculations or evidence of suitability.

Write down whether you are checking a new building, an addition, a change of use, a repair or a single trade package. Identify the rooms, elevations, doors, windows, coatings and interfaces included.
- Assemble the approved baseline. Obtain the latest approved drawings, specifications, schedules, engineering documents, certificates and variations. Mark superseded documents so an outdated detail is not mistaken for the approved one.
- Confirm jurisdiction and classification. Record the state or territory, building use, relevant classification and any special approval conditions. Ask the certifier or building surveyor to confirm these in writing when the project file is unclear.
- Confirm the applicable NCC edition. Check the adoption instrument, commencement date and transitional provisions for that jurisdiction and project. Note every amendment or referenced standard listed in the approval.
- Map requirements to evidence. Create a schedule with one row per relevant performance requirement or approved detail. For each row, identify the drawing, specification, test report, certificate, calculation or inspection record that demonstrates it.
- Identify the compliance pathway. Determine whether the work follows a Deemed-to-Satisfy provision, a documented Performance Solution, or a combination. Do not substitute a product brochure for the pathway decision.
- Inspect the constructed work. Compare dimensions, clearances, materials, fixings, penetrations, seals, interfaces and finishes with the approved documents. Record concealed work before it is covered and photograph locations with a scale or clear reference.
- Check changes and substitutions. List every product, material, thickness, coating system, hardware item or installation method that differs from the approved documents. Obtain a formal assessment before accepting a change, rather than relying on a verbal assurance.
- Resolve gaps. Classify each gap as a documentation problem, an installation defect, a design issue or an unresolved alternative. Assign an owner and due date, and prevent concealment until the disposition is approved.
- Close out independently. Have the responsible designer, engineer, certifier or building surveyor review the completed evidence. Keep the final marked-up drawings, approvals, photographs, test results and correspondence with the handover records.
Deemed-to-Satisfy provisions versus a Performance Solution
These are different ways of demonstrating that the required NCC outcomes have been met. Choosing one is a design and approval decision, not a shortcut made after a failed inspection.
| Pathway | How it is demonstrated | Typical control point | Main risk if handled poorly |
|---|---|---|---|
| Deemed-to-Satisfy | Follow the applicable prescriptive provisions, dimensions, materials and installation conditions. | Check that the built detail matches every relevant condition and referenced standard. | A small substitution or dimensional change can take the work outside the provision. |
| Performance Solution | Use a documented analysis to show that the proposed design meets the applicable performance requirements. | Agree the assessment method, assumptions, evidence and approval before construction. | An informal “equivalent” claim may lack a valid assessment or approval. |
| Combination | Use prescriptive provisions for some elements and a Performance Solution for a defined alternative. | Draw a clear boundary so the alternative does not silently alter the prescriptive portions. | Interfaces between the two approaches can be missed during coordination. |
Evidence that can support a compliance decision
The exact evidence depends on the requirement and the adopted pathway. A robust file usually brings together several types rather than relying on one certificate.
- Approved architectural, structural, services and detail drawings, including revision history.
- Specifications and schedules that identify materials, systems, preparation and installation conditions.
- Test reports, assessment reports, engineering calculations or other evidence of suitability where the requirement calls for it.
- Installation instructions and records showing that the product was used within its tested or assessed scope.
- Inspection, photographic and measurement records for work that will become concealed.
- Non-conformance reports, approved variations and written dispositions from the responsible professionals.
- Final certificates, statements and handover documents required by the project approval.
A supplier statement can describe a product, but it cannot establish that the product was installed in the approved location, with the required substrate, clearances, interfaces or workmanship. Treat labels such as “code compliant” as a prompt to obtain the underlying evidence, not as the evidence itself.
What can happen when a building does not comply?
The outcome depends on the issue, its urgency, the project stage, the authority involved and the applicable state or territory law. The following are possible responses, not automatic penalties.
| When the issue is found | Possible response | What determines the result |
|---|---|---|
| During design or construction | Revised drawings, additional evidence, a hold point, rework or an approved alternative. | Whether the issue can be corrected before concealment and whether the certifier accepts the proposed disposition. |
| At inspection or certification | A request for information, failed inspection, condition on approval or requirement for rectification. | The governing approval process and the significance of the gap. |
| After completion | Investigation, opening-up, repair, replacement, updated documentation or a formal notice. | Evidence available, accessibility of the work and any immediate risk. |
| During occupation or use | Restrictions on use, orders to rectify or other enforcement steps available under local law. | Jurisdiction, building type, affected occupants and the authority’s powers. |
| In a contract or dispute | Defect claims, delay arguments, withheld payment or negotiated settlement. | Contract wording, causation, notice requirements and professional advice. |
Do not predict a fine, prosecution, insurance outcome or demolition from the word “non-compliant” alone. Those consequences require a specific legal and factual basis. If an issue may affect life safety, accessibility or continued occupation, obtain prompt advice from the responsible certifier and an appropriately qualified professional.

Using the wrong edition
Failure: A team applies a familiar clause or old detail without checking the project’s adoption and commencement dates.
Correction: Put the confirmed edition, amendments and transition basis on the compliance schedule and drawing register.
Treating a product label as approval
Failure: A product is described as compliant, but the installation, substrate or interface differs from the assessed configuration.
Correction: Obtain the underlying assessment or test evidence and verify that the installed configuration falls within its scope.
Accepting an undocumented substitution
Failure: A material, coating, door set, window assembly or hardware item is changed to solve availability or cost issues.
Correction: Record the proposed change, assess its effect on each relevant performance requirement and secure written approval before installation.
Leaving interfaces to the last trade
Failure: Waterproofing, fire stopping, access clearances, seals or movement joints are damaged or covered during finishing work.
Do these 3 things before closing this tab:

Relying on memory instead of records
Failure: The work may be correct, but no one can demonstrate what was installed or which decision approved a variation.
Best Value
Correction: Keep revision-controlled drawings, dated inspection notes, photographs, certificates and correspondence in one project file.
Checks for painters and finishes contractors
Painting is rarely the whole compliance question, but finishing work can affect an approved system or hide the evidence needed to verify it. Use the project documents as the controlling source.
- Confirm the specified coating, substrate preparation, primer, number of coats and environmental limits before starting.
- Check whether the finish forms part of a tested or assessed wall, ceiling, door, wet-area or external system; do not assume a visually similar product is interchangeable.
- Protect fire-stopping, smoke seals, acoustic seals, waterproofing, movement joints, drainage paths and access clearances while preparing and coating.
- Coordinate with the door, window, hardware and services trades so paint build-up does not obstruct operation, clearances or seals.
- Record batch numbers, preparation methods, moisture or temperature readings where specified, dates, areas completed and photographs before concealment.
- Raise a written query when the substrate, detail or specified product is different from what is present. Proceeding on an informal instruction can make responsibility difficult to establish.
What the Architecture & Design download does—and does not—establish
The accessible Architecture & Design page identifies Doorway to dreams or disaster? The problem of non-compliance as a downloadable item from the Architecture & Design Team, dated 13 March 2023, and associates it with Wintec Systems. The supplier listing places Wintec Systems in windows, doors, bathroom and laundry products, finishes and flooring.
The page does not expose the downloadable document’s text. It therefore does not establish which incidents, statistics, building failures, legal conclusions or remedies the document discusses. It is accurate to identify the item and its date; it is not accurate to present an unverified thesis or to imply that the supplier association proves a product recommendation. A detailed summary should wait until the actual document and its cited evidence are available.
A concise decision checklist
- Have you recorded the site jurisdiction, building use and approval dates?
- Has the responsible authority or certifier confirmed the adopted NCC edition and amendments?
- Does every relevant requirement have a matching drawing, specification, assessment, test or inspection record?
- Is each element clearly on a Deemed-to-Satisfy pathway, a documented Performance Solution, or an approved combination?
- Have substitutions and site changes been assessed and approved in writing?
- Were interfaces inspected before they were covered by linings, sealants or paint?
- Can the handover file show what was built, who reviewed it and how unresolved items were closed?
If any answer is no, treat it as an information or approval gap first. Do not label the building compliant or non-compliant until the applicable requirement and evidence have been identified by the appropriate project professional.
