Specialist Disability Accommodation (SDA) Explained
What is SDA, who's eligible, the four design categories, how funding works, and how to find SDA vacancies in your area. A plain-English guide to NDIS specialist housing.
Specialist Disability Accommodation (SDA) is purpose-built or significantly modified housing for NDIS participants with extreme functional impairment or very high support needs. It's one of the most sought-after NDIS supports — and one of the most misunderstood.
Only about 6% of NDIS participants qualify for SDA funding, but for those who do, it can fundamentally change their living situation and quality of life.
What is SDA?
SDA is the building itself, not the support services inside it. It's housing that has been built or modified to meet specific accessibility standards. SDA funding covers the cost of the property (paid to the SDA provider, who is essentially a specialist landlord). Your daily support — the support workers who help you in the home — is funded separately under Core supports.
The four SDA design categories
Improved Liveability: Designed for people with sensory, intellectual, or cognitive disability. Features include good lighting, minimal steps, clear visual cues, and a calming, safe environment. Commonly used for people with autism or intellectual disability.
Fully Accessible: Wheelchair-accessible throughout with wider doorways, accessible bathrooms, and kitchen modifications. For people who use a wheelchair or have significant mobility limitations but don't require ceiling hoists or structural features.
Robust: Built to withstand damage, with reinforced walls, secure fixtures, and durable finishes. Designed for participants whose behaviour may result in damage to standard housing. Often combined with other categories.
High Physical Support: The highest level of physical accessibility, including ceiling hoists, structural provisions for assistive technology, emergency power, and heating/cooling in all rooms. For participants with the most significant physical support needs.
Who's eligible?
SDA eligibility requires meeting one of two criteria: extreme functional impairment (very high support needs across most daily activities, typically requiring 24/7 support), or very high support needs combined with housing that is critical to meeting those needs.
Your current living situation, the availability of informal supports, and the cost-effectiveness of SDA versus other housing options all factor into the decision. An SDA assessment is required — typically conducted by an occupational therapist with SDA expertise.
Finding SDA vacancies
SDA vacancies can be searched through the NDIA's SDA Finder, specialist SDA providers in your area, your support coordinator (who should actively monitor vacancies for you), and platforms like the Housing Hub and Summer Foundation's housing database.
Demand for SDA significantly exceeds supply in most areas, particularly for newer, high-quality properties. Being flexible about location and property type increases your options. New SDA developments are being built rapidly across Australia as the market responds to demand.

What percentage of NDIS participants get SDA?
Approximately 6% of NDIS participants have SDA funding in their plans. SDA is reserved for those with the most significant support needs — extreme functional impairment or very high support needs where specialist housing is critical.
How much does SDA cost through the NDIS?
SDA pricing varies significantly based on design category, building type, location, and number of residents. The NDIA publishes separate SDA Pricing Arrangements. Participants don't pay for SDA directly — the funding goes from the NDIA to the SDA provider. Participants pay a reasonable rent contribution (typically up to 25% of the Disability Support Pension).
Can I live alone in SDA?
Yes. SDA is available in various configurations including single-person apartments. However, shared arrangements (2-3 residents) are more common and often more cost-effective. Your preferences should be considered in the SDA assessment and search process.
How do I apply for SDA funding?
SDA must be included in your NDIS plan. Request an SDA assessment from an OT with SDA expertise, who will write a report justifying why SDA is needed. This is then considered at your planning meeting or plan review. Having strong evidence of your support needs and why standard housing isn't suitable is critical.
