Specialist Disability Accommodation (SDA) is an NDIS-funded housing type for people with extreme functional impairment. Delivering compliant SDA requires careful architectural design and a thorough understanding of the NDIS SDA Design Standard across all four design categories.
What Is Specialist Disability Accommodation?
SDA is housing specifically designed or modified for NDIS participants who have very high support needs. Unlike standard social housing, SDA is funded through participants' NDIS plans and delivered by registered SDA providers.
The Four SDA Design Categories
The NDIS SDA Design Standard defines four categories with progressively higher design requirements.
- Improved Liveability — enhanced access features
- Fully Accessible — full wheelchair access
- Robust — reinforced construction for behaviours of concern
- High Physical Support — ceiling hoists and backup power
Key Design Requirements Across All Categories
Regardless of category, all SDA must meet baseline requirements including a step-free path of travel from the street, ground-floor or lift-accessible bedrooms and living areas, accessible bathrooms, onsite participant support worker accommodation where required, and covered drop-off areas.
NDIA Enrolment After Construction
Once constructed, SDA dwellings must be enrolled with the NDIA before participants can be placed. The enrolment process requires certification from an accredited SDA assessor confirming the dwelling meets the Design Standard for the nominated category.
