Of course, most illegal share houses never have problems of this magnitude, but what if.....?
I just don't get it.
I get it. It's because it costs a lot of money to do any works to a building to make it accord with BCA standards.
Most houses these days are classified as Class 1a - meant for occupation by a single family. Builders need to comply with these (relatively) easier standards when it comes to the actual building itself.
Houses used for student accommodation can be classified as Class 1b. This involves a far more onerous imposition by the BCA - hardwired smoke alarms (even for properties built long before the BCA), fire hydrants checked every 6 months, etc
And as you know getting any building surveyor, electrician, engineer etc is extremely expensive...why would anyone bother? Follow the money trail...
