If you’ve been navigating the National Disability Insurance Scheme (NDIS) for a while, you’ve probably come across three terms that seem similar but are actually very different: SIL, SDA, and ILO. And if you’re new to the NDIS world, the acronyms alone can feel like a foreign language.

The truth is, these three housing options—Supported Independent Living (SIL), Specialist Disability Accommodation (SDA), and Individualised Living Options (ILO)—play very different roles in how you (or someone you care for) might live under the NDIS.

So, what do they mean, how do they work, and which option is right for you? Let’s break it down in simple, practical terms.

Why Does Housing Matter So Much in the NDIS?

Finding the right home isn’t just about having a roof over your head, it’s about living in a way that matches your goals, values, and independence. For NDIS participants, housing supports aren’t “one size fits all.” They’re designed to give people choices that align with their personal needs.

That’s where SIL, SDA, and ILO come in. They are funding categories within the NDIS that support different aspects of where and how you live.

But here’s the catch: each option serves a specific purpose, and misunderstanding them can lead to choosing the wrong path, or missing out on supports you’re entitled to.

What is Supported Independent Living (SIL)?

Supported Independent Living (SIL) is funding for daily support services. It’s not about the bricks and mortar of your home, it’s about the help you get inside it.

Think of SIL as:

• Assistance with personal care (showering, dressing, eating).
• Support with household tasks (cooking, cleaning, shopping).
• Help with developing skills to live more independently.
• Round-the-clock support in some cases, depending on your needs.

Who is SIL for?

SIL is best suited for people who need regular, ongoing support, often in a shared living arrangement with other participants. If you need a high level of help every day to manage your life safely, SIL could be right for you.

Important note: SIL does not fund your rent, mortgage, or the physical home. It only covers the support services.

What is Specialist Disability Accommodation (SDA)?

Now let’s talk about the physical building itself. That’s where Specialist Disability Accommodation (SDA) comes in.

SDA is the funding for the housing itself. It’s about building or modifying homes designed for people with significant functional impairments or very high support needs.

Features of SDA homes often include:

• Wheelchair accessibility.
• Wider hallways and reinforced bathrooms.
• Smart-home technology to support independence.
• Emergency response systems.

Who is SDA for?

Only a small percentage of NDIS participants are eligible for SDA, around 6% according to the NDIS Quarterly Report. It’s meant for people whose disability is so significant that they need a specially designed home to live safely and comfortably.

Key difference from SIL: SDA funds the home, while SIL funds the support within the home. Many people with high support needs receive both types of funding, SDA for the building and SIL for the care.

What is Individualised Living Options (ILO)?

Now here’s where it gets flexible. Individualised Living Options (ILO) is all about tailoring your living arrangement to suit your lifestyle and preferences.

Instead of being locked into a group home or specialist accommodation, ILO lets you design your own model of support.

Examples of ILO arrangements might include:

• Living in your own home with a support worker who checks in daily.
• Sharing a place with a flatmate who provides informal support.
• Having a “host arrangement,” where you live with a family who supports you.
• Blending formal paid support with informal help from friends, family, or community networks.

Who is ILO for?

ILO works best for people who don’t need 24/7 intensive support but still benefit from a structured living arrangement. It’s about choice and flexibility, perfect if you want independence but still need some backup.

How is ILO different from SIL?

• SIL is structured, with rostered staff and more formal, ongoing support.
• ILO is customised, often mixing formal and informal supports.

Quick Comparison: SIL vs SDA vs ILO

Here’s a simple way to look at the three side by side:

Option	What It Covers	Who It’s For	Example
SIL	Support services (daily living assistance)	People who need regular or 24/7 help	Shared living with staff providing personal care and skill-building support
SDA	The physical home (specially designed or modified)	People with very high physical needs	A fully accessible home with assistive technology features
ILO	Flexible, tailored support arrangements	People who want independence with some support	Living with a flatmate who provides support, plus occasional paid carers

Which Option Should You Choose?

Choosing between SIL, SDA, and ILO isn’t just about eligibility, it’s about your goals and lifestyle.

Ask yourself:

• Do I need ongoing, daily support to stay safe? → SIL may be the right fit.
• Is my disability so significant that I need a specially built or modified home? → SDA could apply.
• Do I want flexibility and a more personalised arrangement that balances independence with support? → ILO might be best.

It’s also worth noting that these options aren’t always mutually exclusive. Some participants may receive both SDA and SIL funding, or combine ILO with other supports.

Common Myths About SIL, SDA and ILO

Myth 1: SDA pays for my support workers.
Nope. SDA only funds the house. Support workers come under SIL or ILO.

Myth 2: ILO is the same as SIL.
Not true. SIL is structured and staff-led, while ILO is flexible and participant-led.

Myth 3: Everyone can get SDA.
Only a small percentage qualify, based on strict eligibility criteria.

What’s the Process for Accessing These Supports?

1. Talk to your Support Coordinator or Planner about your goals.
2. Gather evidence from therapists, doctors, and other professionals to show your support needs.
3. Request the right category of funding in your NDIS plan review.
4. Work with providers to find housing options that match your approved funding.

The Future of NDIS Housing

The NDIS is still evolving, and housing options are expanding. Demand for SDA homes is growing, while ILO is becoming more popular among participants who want control over their living arrangements.

According to the NDIS 2024 data, more than 19,000 participants now live in SDA, and ILO approvals are steadily rising. The trend is clear: the system is shifting toward choice, flexibility, and independence.

Final Thoughts: Finding the Right Home Under the NDIS

At the end of the day, SIL, SDA, and ILO are three very different pieces of the NDIS housing puzzle.

• SIL = Support services.
• SDA = The house.
• ILO = Flexible living options.

The best choice depends on your level of support needs, your goals for independence, and what feels right for your lifestyle.
