Confused about SIL and SDA? Learn the key differences between Supported Independent Living and Specialist Disability Accommodation under the NDIS.
4 min read
If you're researching NDIS housing options, you've likely come across the terms Supported Independent Living (SIL) and Specialist Disability Accommodation (SDA).
While these supports are often mentioned together, they serve very different purposes. SIL funds the support you receive to live independently, whereas SDA funds the specialist housing itself.
Understanding the difference between SIL and SDA can help you make informed decisions about your NDIS plan, housing options, and support needs.
In this guide, we'll cover:
- What SIL is
- What SDA is
- The key differences between SIL and SDA
- Who may be eligible
- Whether you can receive both supports
What Is Supported Independent Living (SIL)?
Supported Independent Living (SIL) is an NDIS-funded support that helps people with disability live as independently as possible by providing assistance with everyday activities.
It's important to understand that SIL funds the support you receive—not the home you live in.
Depending on your needs, SIL can include support with:
- Personal care
- Meal preparation
- Household tasks
- Medication assistance
- Developing independent living skills
- Community participation
- Overnight support
- 24-hour support where required
The focus of SIL is helping participants build confidence, increase independence, and achieve their personal goals while living safely in their chosen home.

What Is Specialist Disability Accommodation (SDA)?
Specialist Disability Accommodation (SDA) is a type of housing funded by the NDIS for participants with extreme functional impairment or very high support needs.
Unlike SIL, SDA does not pay for support workers. Instead, it funds the physical home itself.
SDA homes are purpose-built or significantly modified to improve accessibility, safety, and independence.
These homes may include features such as:
- Wider doorways for wheelchair access
- Ceiling hoists
- Accessible bathrooms
- Adjustable kitchen benches
- Emergency backup power
- Assistive technology integration
SDA enables participants to live in homes that meet their specific accessibility requirements.
Who Is Eligible for SIL and SDA?
SIL Eligibility
Supported Independent Living (SIL) may be suitable for NDIS participants who require regular support with daily tasks due to their disability. Eligibility is based on an individual's support needs and whether SIL is considered a reasonable and necessary support under the NDIS.
SDA Eligibility
Specialist Disability Accommodation (SDA) is available to a small proportion of NDIS participants with extreme functional impairment or very high support needs. Funding is only approved where specialist housing is necessary to support a participant's goals, independence, and quality of life.
SIL vs SDA: Key Differences
| Feature | SIL | SDA |
|---|---|---|
| What it funds | Support services | Specialist housing |
| Purpose | Daily living assistance | Accessible accommodation |
| Support workers included | Yes | No |
| Housing included | No | Yes |
| Focus | Personal support | Physical environment |
| Can be used together | Yes | Yes |
Frequently Asked Questions:
Can You Receive Both SIL and SDA?
Yes. Many participants receive both where specialist accommodation and daily support are required.
For example: Sarah uses a powered wheelchair and requires assistance with most daily activities.
She lives in an SDA apartment with:
- Wheelchair-accessible entrances
- Ceiling hoists
- Automated doors
She also receives SIL funding, which provides support workers to assist with personal care, meal preparation, medication, and community participation.
In this example:
- SDA pays for the specialist home.
- SIL pays for the support workers.
The two supports complement each other but serve different purposes.
Does SIL pay for rent?
No. SIL covers support services rather than accommodation costs.
Is SDA available to all NDIS participants?
No. SDA is only available to participants with extreme functional impairment or very high support needs.
Is SIL the Same as SDA?
No. SIL funds the support services that help participants with daily living activities, while SDA funds specialist housing designed to meet accessibility and support needs.
