Difference Between SDA and SIL

Navigating the National Disability Insurance Scheme (NDIS) can be confusing, especially when it comes to housing and daily support services. Two important NDIS-funded supports are Specialist Disability Accommodation (SDA) and Supported Independent Living (SIL). Though they are often used together, they serve very different purposes.

In this blog, we’ll break down the difference between SDA and SIL, so you can better understand how they fit into your NDIS plan—and your path to greater independence.

What is Specialist Disability Accommodation (SDA)?

SDA refers to the bricks-and-mortar housing built specifically for people with extreme functional impairment or very high support needs.
It is:

Funded by the NDIS to cover the cost of the building or dwelling
Designed for accessibility, safety, and long-term accommodation
Categorized into four levels:

Improved Liveability
Fully Accessible
High Physical Support
Robust

SDA is only available to a small percentage of NDIS participants who meet specific criteria.

SDA Focus:
The physical environment — Where you live

What is Supported Independent Living (SIL)?

SIL refers to the support services provided to help you live independently in your home.
These are:

Staff and carers who help with daily tasks like cooking, cleaning, personal care, medication, and transport
Provided in shared homes, individual dwellings, or SDA settings
Funded separately from SDA in your NDIS plan

You can receive SIL in an SDA property, a rental home, or even a private residence.

SIL Focus:
The daily support — How you live

Key Differences: SDA vs SIL

Your home is your foundation — especially when you're living with a disability.
Choosing the right SDA provider ensures:

Feature	SDA (Specialist Disability Accommodation)	SIL (Supported Independent Living)
Purpose	Housing specifically designed for high needs	Daily living support and personal assistance
NDIS Funding	Covers cost of building or dwelling	Covers cost of support staff and services
Eligibility	Small percentage of participants	More widely available to those needing daily help
Can Be Used Together?	Yes	Yes
Provided By	SDA provider (e.g., First Care Choice)	SIL provider or care agency
Examples of Services	Accessible design, ceiling hoists, safety features	Showering, dressing, meal preparation, meds

Do You Need Both SDA and SIL?

Not necessarily. It depends on your needs.

If you require special housing but can live independently, you might only need SDA.
If you need support with daily living but don’t require specialist housing, SIL in a standard home might be enough.
Many participants require both — living in an SDA home with SIL support.

Your NDIS plan will outline eligibility and funding based on your functional capacity, support needs, and goals.
