NDIS SIL vs SDA: Which Supported Living Option Suits You Best?
When it comes to NDIS housing supports, one of the most common questions participants and families ask is: “SIL vs SDA – which one is right for me?” Both Supported Independent Living (SIL) and Specialist Disability Accommodation (SDA) are crucial NDIS-funded supports designed to help people with disability live more independently. However, they serve different purposes, have different eligibility criteria, and suit different needs.
In this detailed guide, we will break down SIL vs SDA—what they are, how they work, who is eligible, and the key factors to consider when deciding which option best matches your lifestyle and support needs.
What is Supported Independent Living (SIL)?
Supported Independent Living (SIL) is a type of NDIS funding that covers the cost of personal support services for people living with disability. It is designed for participants who need help with daily living tasks, such as:
- Meal preparation and cooking
- Cleaning and laundry
- Medication management
- Personal care and hygiene
- Shopping and budgeting
- Developing life skills
Key point: SIL funding does not cover the cost of your accommodation (rent, mortgage, or utilities). Instead, it funds the support workers who assist you in your home.
Best suited for:
- People with higher support needs
- Those who require regular or 24/7 care
- Participants living in shared housing arrangements or with housemates
What is Specialist Disability Accommodation (SDA)?
Specialist Disability Accommodation (SDA) is NDIS funding for purpose-built or specially modified housing designed for people with very high support needs or extreme functional impairment.
SDA properties are designed to improve accessibility, safety, and independence. Features may include:
- Wheelchair-accessible layouts
- Hoists, lifts, or adjustable benches
- Assistive technology integration
- Wide doorways and hallways
- Emergency response systems
Key point: SDA funding covers the cost of the physical building, but not the daily living support. You can receive SIL and SDA together if you need both specialised housing and daily living assistance.
Best suited for:
- People who require a specially designed home due to their disability
- Participants with very high physical support needs
- Those needing structural modifications for safety and accessibility
SIL vs SDA: The Main Differences
Understanding the SIL vs SDA difference is essential to make the right decision for your NDIS plan.
| Feature | SIL (Supported Independent Living) | SDA (Specialist Disability Accommodation) |
|---|---|---|
| Purpose | Covers cost of support workers | Covers cost of specialised housing |
| Funding covers | Daily living assistance | Purpose-built or modified home |
| Accommodation included? | ❌ No | ✅ Yes |
| Best for | People needing daily living support | People needing specially designed housing |
| Eligibility | Higher support needs | Extreme functional impairment/high needs |
| Can be combined? | ✅ Yes | ✅ Yes |
Can You Have SIL and SDA Together?
Yes, many participants receive both SIL and SDA in their NDIS plan. This is common when someone needs both specialised housing and ongoing daily support. For example:
- You might live in an SDA property with wheelchair accessibility and safety features.
- At the same time, you receive SIL services from support workers who help with cooking, cleaning, and personal care.
This combination ensures you have the right home environment and the right support to live as independently as possible.
Eligibility Criteria for SIL vs SDA
SIL Eligibility
To receive SIL funding, you must:
- Have higher support needs requiring help with daily activities
- Be approved by the NDIS after an assessment
- Live in a shared arrangement or require support throughout the day/night
SDA Eligibility
To receive SDA funding, you must:
- Have an extreme functional impairment or very high support needs
- Require a home with specialised design features
- Meet the NDIS housing assessment requirements
How to Decide: SIL vs SDA
Choosing between SIL vs SDA depends on your primary needs:
- If you mainly need personal support for daily living tasks → SIL is likely the right choice.
- If you mainly need a specially designed home for accessibility and safety → SDA is more suitable.
- If you need both → You can have both SIL and SDA funding together.

Sarah uses a wheelchair and requires a fully accessible bathroom, ramps, and automated doors but can manage her daily living independently. She receives SDA funding for her specialised home.
Case 3 – SIL + SDA:
Michael has cerebral palsy and requires a wheelchair-accessible home and assistance with daily living. He receives SDA for his home and SIL for personal support.
