Summary
The part of Australia's model building code that sorts buildings into classes; its explanatory information places churches in Class 9b, the class whose rooms trigger the code's hearing augmentation clause.
Key findings
- Clause A6G10 defines Class 9 buildings as buildings of a public nature, and Class 9b as an assembly building, including a trade workshop or laboratory in a primary or secondary school.
- Its explanatory information says Class 9b buildings can include theatres, cinemas and halls, churches, schools, early childhood centres, sports centres and stadiums, nightclubs, public halls and dance halls, and bus and railway stations.
- Says a building can be a mixture of Class 9b and another class, or be treated as Class 9b as a whole when another use takes up only a small part of a storey.
Limits
The list of examples that names churches sits in explanatory information under the clause; the clause itself says only "assembly building". It names churches but not synagogues, mosques or temples. NCC 2025 was published on 1 May 2026 and is adopted by states and territories on their own dates, so NCC 2022 may still apply. The hearing augmentation rules themselves are in Part D4 (a separate record).
