An indoor clothes drying line must be a fixed (permanent) installation that is not heated by a dedicated gas or electric heater (it may be heated using waste heat from another appliance – you will need to apply for an alternative assessment if you wish to claim the greenhouse savings of doing this). For more information see the BASIX Clothes Drying guideline.
See also the BCA provisions for minimum indoor clothesline length or laundry facility size in multi-unit apartments (Table F2.1, Vol. 1, BCA 2005)
A sheltered clothes drying line is a fixed (permanent) outdoor clothes line that is protected from the rain, eg. On a covered balcony or under a verandah.
Examples of indoor or sheltered clothes drying lines include a screened line on balconies and an extendable line over a bath.
