External rooftop areas of buildings that are designed for use as amenity spaces for building occupants must be made accessible to people with disabilities. This includes rooftop terraces, patios and barbecue facilities and requires that a barrier-free path of travel be provided from the floor area to the rooftop amenity space. Exterior roof spaces that are only accessed for the purpose of building and equipment maintenance and operations are not required to be barrier-free accessible and will continue to be exempt from barrier-free design requirements under Clause 3.8.2.1.(3)(f).
