SDA is about an eligible specialist home. SIL is about the personal support someone needs at home. The names often appear together, but one doesn't automatically include the other.
Keeping that distinction clear helps you ask the right questions before agreeing to a property or support arrangement.
Compare the two
| SDA | SIL | |
|---|---|---|
| What it concerns | Specialist housing with disability-related design features | Assistance with daily activities at home |
| What to ask about | Approved design, building type, location and your contribution | The support delivered, staffing arrangement and how your needs are met |
| What it doesn't automatically cover | Personal care and daily support | Rent, groceries and ordinary household bills |
The NDIS SDA guide explains who specialist accommodation is for. Its purpose is different from ordinary rental housing.
Can you have one without the other?
Yes. Someone may receive SIL in a home that isn't SDA. Someone in SDA may have a different arrangement for their personal support. The relevant approvals and the person's needs determine the arrangement.
Ask your my NDIS contact what is in your plan and what still needs a decision. A provider's offer isn't the same as NDIA approval.
Questions before you agree
- Which organisation is responsible for the housing and which delivers support?
- Can I choose or change my support provider?
- What do I pay myself, and what is claimed from my plan?
- What happens if my needs or household arrangements change?
- How are concerns, repairs and urgent support handled?
Read each agreement separately. Ask for time to get advice if the terms are unclear.
Think about everyday life
The right arrangement also needs to work with transport, relationships, routines and the community you want to be part of. A technically suitable property can still be the wrong fit for you.
Our South Australian housing guide helps you compare those practical details. Check transport costs before making a move.
