Who checks compliance when building a home?

In Australia, building compliance is checked by an accredited certifier or building surveyor. Their role is to ensure your project meets all legal and technical requirements under the National Construction Code (NCC), relevant Australian Standards, and local planning rules. They inspect key stages of construction and issue the final Occupation Certificate, which confirms your home is safe, compliant, and ready to be lived in.

What does a certifier do?

• Reviews your plans before construction starts to ensure they meet building regulations and approvals.

• Issues the Construction Certificate (or Building Permit), which allows work to begin.

• Conducts mandatory inspections at key stages, such as foundations, framing, waterproofing, and final fit-out.

• Checks compliance with structural safety, fire protection, energy efficiency, and accessibility standards.

• Issues the Occupation Certificate once the build is complete and compliant.

Independence matters

To maintain integrity and avoid conflicts of interest:

• The certifier must not be related to the builder or developer.

• They are generally appointed by the owner (in some states the builder cannot appoint them on your behalf) and must hold current registration or accreditation under state or territory legislation, e.g. NSW’s Building and Development Certifiers Act.

• Certifiers are subject to strict professional conduct rules and can face penalties for misconduct or negligence.

Why it’s important

• Ensures your home is built to legal and safety standards

• Protects you from future liability or insurance issues

• Required for final approval and occupancy

• Helps avoid costly mistakes or non-compliant work

Bottom line: An accredited certifier or building surveyor is your compliance watchdog. They’re independent professionals who inspect your build, verify it meets all regulations, and issue the final certificate that allows you to move in. Choosing a qualified, impartial certifier is essential for a safe and legally approved home.
