Ask with clause references

Every answer points to the NCC (2025 or 2022, depending on your state), Housing Provisions or referenced standard clause it's based on.

Inspectors and certifiers

Write consistent, sourced reports from Ask and photo checks faster.

What's different in Australia

Regulator: Australian Building Codes Board (NCC)

One national code, eight sets of state rules

The National Construction Code (NCC) sets the technical standard across Australia, but each state and territory adopts it through its own laws and adds its own licensing, inspection and approval rules.

Source

NCC 2025, adopted at different times

NCC 2025 took effect on 1 May 2026 in Victoria, WA and the ACT (WA and the ACT allow NCC 2022 until 1 May 2027). NSW, Queensland and Tasmania stay on NCC 2022 until 1 May 2027. SA uses NCC 2025 for plumbing now and for building from 1 May 2027. The NT hasn't adopted NCC 2025. Each state page shows which edition applies.

Source

Inspections vary by state

Most states require the builder to notify a building surveyor or certifier at set stages such as footings, frame and completion. The stages, and who inspects, differ by state.

FAQ

Does ComplianceApp replace my building surveyor or certifier?

No. It helps you find and understand the requirements, but approvals, inspections and certificates still come from a registered building surveyor, certifier or licensed practitioner.

Source

Which edition of the NCC does it use?

Both NCC 2025 and NCC 2022, because states adopt editions on different dates. Answers note which edition applies where you build.

Source

Does it cover my state?

National Ask and photo answers apply everywhere. Every checklist has national items plus state items where the rules differ. Each state page shows what's covered.
