A BAL Certificate must state the development is not BAL-40 or BAL-FZ before a
complying development certificate can issue. The rating decides which approval route is
available, not just what has to be built.
The construction rules are behind a $286.63 licence. The step that decides
which BAL applies in NSW is not: Appendix 1 of Planning for Bush Fire
Protection 2019 replaces Section 2 of AS 3959, and the RFS publishes it free.
AS 3959 decides what a compliant shutter is. What reading it costs, the
free-access commitment in the May Budget, and the date nobody has published
yet.
