David2708 – My experience as a Qlder has been that the interpretation by Adjudicators of this type of by-law is not as strict as you are suggesting. Draping of laundry over a balcony railing would not be permitted but small discreet clothes lines are OK. After all, no one wants to hang their ‘intimate apparel’ on a public clothes line …. do they?
Some people don’t own or don’t want a clothes dryer, and some types of clothing materials are wrecked by being placed in a clothes dryer.
