Current Disability Access Provisions under BCA Part D3

AUST  Hendry building surveying consultants advise that the amendments to the Building Code of Australia (BCA) and the introduction of AS 1428.1-2009, that superseded the previous AS 1428.1-2001 (disability access code) edition, resulted in some significant changes to the disability access and toilet facilities provisions for people with disabilities. Some of the major Disability Discrimination Act changes, implications and concessions applicable to buildings under building approvals are as follows. Note that the reference to ‘accessible’ in the items below is “having features to enable use by people with a disability” not just defined as exit doors, and to ‘ambulant’ disabilities is “people who have a mobility disability but are able to walk”, different to egress under the BCA.

  • In buildings with a total floor area of more than 500m², a pedestrian entrance that is not accessible for people with disabilities must not be located more than 50m from an accessible pedestrian entrance.Where a doorway has multiple leaves (except an automatic opening door) one of the leaves must have a clear opening width of not less than 850mm.
