SDA houses are built to fit within one of the five SDA categories:
Basic – housing that doesn’t include specific design features, and was normally built before the NDIS rolled out. Funding for this is only included in an NDIS plan if an individual has lived in ‘basic’-level housing before, and chooses to continue living there.
Improved Liveability – housing that includes better physical access and has features for people with sensory, intellectual or cognitive impairments.
Fully Accessible – housing that includes a high level of physical access features for people with physical challenges.
Robust Construction – housing that includes a high level of physical access, is strong and durable, and is built to make daily living safe for everyone, making them ideal properties for individuals who display behaviours of concern.
High Physical Support – housing that includes a high level of physical access for people with significant physical disabilities, designed to support people who require very high levels of support.
The category of housing depends on the specific support needs of the individual residents, that are determined in a functional assessment.
The five categories have differing minimum accessibility requirements.
