Current legal requirements
There is a legal requirement to make sure that people with a disability have access to a range of public buildings in Australia.
The legislation that must be followed relates to access to premises / buildings is the Commonwealth's Disability Discrimination Act 1992 (DDA) (external link) and the Premises Standard 2010 (external link) which is referred to in Volume One of the National Construction Code (NCC 2016)(external link).
These documents are the law in Tasmania – the NCC provides technical requirements.

For more information on accessible features of a building read the Australian Standard AS1428 (2009) "Design for Access and Mobility" Part 1: General Requirements for Access – New Building Work; and other relevant parts as referenced by the NCC 2016 (National Construction Code)as the legal technical requirement for new building work.
Alterations to an existing building may need a building permit to comply with the National Construction Code disability access provisions. When no building work is being done on an existing building there is no need to upgrade the building to NCC standards, including compliance with disability access requirements.
