Hi, I recently had an electrician install a new ceiling exhaust fan in the ensuite bathroom as there was not one there already and I could see some mould forming in one of the roof corners. There is a window in the bathroom. The fan is vented into a drop ceiling and not ducted outside. I didn't know that I needed strata approval to do this (it's a unit). I am now concerned that this will cause issues in the long-term if the moisture is going into the roof and not outside. But given it is a drop ceiling is this okay? How can I get assurance that this won't cause issues? I am on the ground floor. Should I remove the fan? Replace the piece of drop ceiling it was mounted to?
