I don't understand how an HOA can have a rule which directly violates building codes and in the case of dryers is just plain stupid. The cost of moisture problems including mold overtime for indoor vented dryers is going to be pretty monumental. There are condensing dryers (popular in Europe) but the are small, expensive and can take a long time to do a land of laundry. Someone needs to shake up your HOA .
I have no ventilation in my bathroom either. During the winter, I hate using that particular one, because it's too cold. Also, three to four times a month I have to put hot water and bleach in the tub to keep mold from growing out of control. I would like to have this fixed. Is even possible to put ventilation in, or am I out of luck?
