Decoding head height requirements for Parking spaces for people with Disabilities

There are 2 types of parking spaces identified suitable for people with Disabilities by the Australian Standards. AS/NZS 2890.6-2009 (Parking facilities—Off-street parking for people with disabilities) identifies a space of length 5.4M with a width of 2.4M allocated to a dedicated accessible parking space with an additional 2.4M width as a shared zone and AS4299-1995 (Adaptable Housing) which identifies a space of 3.8M width and 6M length. Both recommend a head height of 2.5M (although it is to be noted that the head height requirement is not an essential criteria of AS4299-1995 i.e. Class C Compliance).The head height requirements are mainly due to the use of ceiling hoists for wheelchairs as shown in the diagram below. The most popular car ceiling hoist in Australia is the Wymo Hoist. Due to the swinging arm of the ceiling hoist a 2.5M head height clear of any obstructions such as beams or sprinklers is required.
