SIL vs SDA: How to Navigate NDIS Plan Housing Supports in Australia

Most participants and families feel overwhelmed when they first hear about Supported Independent Living (SIL) and Specialist Disability Accommodation (SDA). The names sound similar, but the difference between them can mean the world when you’re planning your next home and support needs under the NDIS.

Key takeaways

• SIL and SDA are two separate NDIS supports: SDA funds the home, while SIL funds the support people in the home.
• Not everyone who gets SIL will get SDA, and vice versa—eligibility and assessment are different for each.
• You can use SIL in ordinary homes, not just SDA properties, but SDA is only for those with the highest needs.
• Knowing the difference helps you ask for the right funding at your next planning meeting and avoid common funding traps.

Why This Is Genuinely Hard

NDIS housing funding is confusing—even for experienced participants and families. SIL and SDA are often mentioned together but cover totally different things. The names don’t make this clear. Many participants worry they’ll ask for the wrong thing, or miss out on funding they need because they don’t know how to explain their situation. It’s easy to think you need both, but most people receive only one or the other. In our experience at LuminCare, the most common trap is assuming you need SDA to get support in your home, or not realising you can access SIL in a regular house or rental. The eligibility criteria are strict, and the paperwork can be daunting. Even support coordinators sometimes mix up which funding pays for what.

How It Actually Works: SIL vs SDA Difference Explained

Supported Independent Living (SIL) is NDIS funding for daily living support. This pays for trained staff to help you with things like cooking, cleaning, showering, or going out in the community. SIL is about the people who support you, not the house itself. You can get SIL in group homes, share houses, or even your own rental. The NDIA funds SIL for participants who need help all the time—usually 24/7 or at least most of the day (NDIS Pricing Arrangements, 2026).

Specialist Disability Accommodation (SDA) is NDIS funding for the bricks-and-mortar house itself. SDA pays for specially designed homes for people with very high physical needs or extreme functional impairment. These homes might have things like wide doorways, ceiling hoists, or high-tech safety systems. Only about 6% of NDIS participants get SDA funding, and there are strict eligibility rules (NDIA, SDA Operational Guideline, 2026). SDA never pays for support staff—that’s what SIL is for.

You can have:

• SIL only (support in a regular home)
• SDA only (live in a special home, but get support in other ways)
• Both SIL and SDA (if you have very high needs and meet both criteria)

Key NDIS funding categories:

• SIL: Core Supports > Assistance with Daily Life
• SDA: Capital Supports > Specialist Disability Accommodation

Eligibility:

• SIL: Need help with daily tasks most of the time, usually with a strong functional assessment (e.g., OT report)
• SDA: Extreme functional impairment or very high support needs, plus evidence that SDA is the only suitable long-term housing (NDIA, SDA Operational Guideline, 2026)

Funding ranges:

• SIL: Varies widely, from $70,000–$350,000 per year depending on your support ratio and needs (NDIS Pricing Arrangements, 2026)
• SDA: The NDIA pays the property provider directly—participants never see this money. SDA payments range from $12,000–$80,000 per year (NDIA, SDA Pricing Arrangements, 2026)

Your Step-by-Step Action Plan

1. Work out your needs.
   • Write down what help you need each day (e.g., getting up, eating, personal care, taking medication).
   • Ask your OT, support coordinator, or trusted person to help you list your daily tasks.
2. Gather evidence.
   • For SIL: Get recent reports from your occupational therapist, psychologist, or doctor explaining why you need daily support.
   • For SDA: You’ll need extra assessments showing extreme functional impairment and why a regular home isn’t enough (ask for an 'SDA Housing Assessment').
3. Decide what to ask for.
   • If you mainly need support people, ask for SIL funding.
   • If you need a highly modified home, ask about SDA as well. Remember, you can have SIL without SDA.
4. Prepare for your planning meeting.
   • Bring your evidence and a clear list of what supports and housing you need now and in the future.
   • Use the words: “I am requesting Supported Independent Living funding for daily support” and/or “I am requesting Specialist Disability Accommodation funding because I need a specially designed home.”
5. Review your draft NDIS plan.
   • Check the 'Core Supports' and 'Capital Supports' sections for SIL and SDA funding.
   • If anything is missing, ask for a review or talk to your support coordinator.
6. Find the right home and support.
   • If you get SIL, look for providers who offer support in the type of home you want (share house, apartment, etc.).
   • If you get SDA, search for registered SDA properties in your area (including SIL accommodation in Melbourne if you live locally).
7. Sign agreements separately.
   • Remember: Your ‘SIL Service Agreement’ is with your support provider. Your ‘SDA Tenancy Agreement’ is with the housing provider. Keep them separate to protect your rights.

Real Example

Let’s say Alex is a participant with high physical needs who uses a wheelchair. Alex needs help with all daily tasks, including showering, dressing, and getting in and out of bed. Alex’s occupational therapist writes a detailed report showing that standard housing is unsafe for Alex, and that Alex needs a home with ceiling hoists and wide doorways. At the NDIS planning meeting, Alex and their support coordinator request both SIL (for daily support) and SDA (for a fully accessible home).

The NDIA funds both after reviewing the evidence. Alex moves into an SDA apartment in Melbourne and receives SIL funding for a team of support workers. What worked for Alex was having clear, specific reports and knowing to apply for both supports separately. Many participants can replicate this by gathering strong evidence and being clear about their needs and goals at the planning meeting.

Frequently Asked Questions

What is the main difference between SIL and SDA?

Supported Independent Living (SIL) funds daily support people in your home, while Specialist Disability Accommodation (SDA) funds the special building or home itself. SIL is about support; SDA is about the property.

Do I need both SIL and SDA to get support at home?

No, most participants only get one or the other. You can receive SIL in a regular home, and SDA is only for those with very high needs who require a specially designed home.

How do I apply for SIL or SDA funding in my NDIS plan?

You need to gather evidence (like occupational therapy reports) and clearly ask for SIL or SDA at your NDIS planning meeting. Each has its own eligibility requirements and assessment process.

Can I get SIL funding in an ordinary rental house?

Yes, you can receive SIL in an ordinary house, apartment, or share house. SIL funding is not limited to specialist homes like SDA properties.

Who decides if I get SDA funding?

The NDIA decides if you meet the strict eligibility criteria for SDA, based on evidence from your reports and assessments showing you have extreme functional impairment or very high support needs.
