Navigating the National Disability Insurance Scheme (NDIS) can feel overwhelming, especially when you encounter similar-sounding terms like Specialist Disability Accommodation (SDA) and Supported Independent Living (SIL). Many families wonder whether they're the same thing, if you need both, or which one is right for their situation.

The key difference between SDA and SIL is that SDA (Specialist Disability Accommodation) funds the physical, specially designed housing itself - the 'bricks and mortar' - while SIL (Supported Independent Living) funds the support services and staff who help with daily living tasks like cooking, cleaning, and personal care. You can receive funding for one, both, or neither, depending on your individual needs and NDIS plan.

Understanding this distinction is the first step in making informed decisions about your housing and support options. This guide explains exactly what each term means, how they differ, and how they can work together to support independent living.

What is Specialist Disability Accommodation (SDA)?

Specialist Disability Accommodation (SDA) is NDIS funding for the physical housing itself. Think of it as the building - the actual bricks and mortar of your home.

SDA properties are purpose-built or modified to meet specific accessibility and design standards. These homes feature specialized design elements that standard housing doesn't provide, such as wheelchair-accessible bathrooms with roll-in showers, wider doorways and hallways, ceiling hoists in bedrooms and bathrooms, and automated door systems.

The NDIS funds SDA because some people with disability need housing that's specifically designed for their support needs. Standard rental properties simply can't provide the same level of accessibility and safety features.

There are four SDA design categories, each designed for different support needs:

• Improved Liveability - for people with sensory, intellectual, or cognitive impairment
• Fully Accessible - for people who use wheelchairs or have significant physical impairment
• High Physical Support - with ceiling hoists and specialized equipment for people requiring extensive physical assistance
• Robust - with reinforced features for people with complex behavioural support needs

SDA funding doesn't cover the support services you receive in the home. It only covers the cost of the specialized housing itself. You don't pay rent for SDA housing out of your own pocket - the NDIS pays the housing provider directly.

Learn more about what SDA is and how it works to understand if it's right for your circumstances.

What is Supported Independent Living (SIL)?

Supported Independent Living (SIL) is NDIS funding for the support services and staff who help you with daily living tasks. Think of it as the people who support you, not the building you live in.

SIL funding covers assistance with everyday activities like meal preparation and cooking, personal care and hygiene, household tasks and cleaning, medication management, community participation, and developing independent living skills.

The goal of SIL is to help you live as independently as possible while receiving the support you need to manage your daily routine. SIL support is provided by qualified support workers who may visit your home at scheduled times or live on-site, depending on your needs.

SIL is flexible and personalized. Your SIL support plan is tailored to your specific needs, goals, and preferences. Some people need assistance a few hours a week, while others require 24/7 support.

You can receive SIL support in any living arrangement - not just in SDA housing. You might receive SIL support in your family home, a standard rental property, your own home, or in SDA housing specifically designed for accessibility.

The key difference is that SIL pays for the staff and services that support you, while the location where you receive that support is separate.

Key Differences Between SDA and SIL

Understanding how SDA and SIL differ helps you identify which type of funding applies to your situation.

What it funds:

• SDA funds the physical housing - the specially designed building itself with accessibility features
• SIL funds the support services - staff who help with daily tasks like cooking, cleaning, and personal care

What it is:

• SDA is accommodation - the actual home or apartment you live in
• SIL is support - the people and services that assist you in daily living

Who provides it:

• SDA is provided by registered housing providers like Paramount Disability Homes who own and manage the properties
• SIL is provided by registered support providers who employ support workers and coordinators

Eligibility focus:

• SDA eligibility focuses on whether you need specialized housing design due to significant disability that can't be met by standard housing
• SIL eligibility focuses on whether you need regular support to live independently and manage daily tasks

Your role:

• In SDA, you're a tenant with tenancy rights and responsibilities, choosing where you want to live based on location and design
• In SIL, you're directing your support, choosing your support provider and determining how support is delivered

Provider role:

• SDA providers maintain the property, handle repairs, and ensure the home meets accessibility standards
• SIL providers deliver personal support services, coordinate care, and help you achieve your independence goals

Can they work together:

• Yes - SDA and SIL are separate funding categories that often work together, with SDA providing accessible housing and SIL providing daily living support in that home

The critical point to understand is that these are two distinct types of NDIS funding. Having one doesn't automatically mean you have or need the other.

Eligibility: Who Can Access SDA and SIL?

SDA and SIL have different eligibility criteria because they address different needs.

SDA Eligibility Requirements:

To receive SDA funding, you must meet specific criteria set by the NDIS. You need to have extreme functional impairment or very high support needs related to your disability. The NDIS assesses whether you require specialized housing design that's not available in standard rental properties.

You'll need to demonstrate that SDA will improve your ability to live independently, increase your participation in community and social activities, and provide better value compared to other housing options.

The NDIS also considers whether SDA is a reasonable and necessary support for you. This means evaluating if the specialized housing will make a significant difference to your quality of life and independence.

Check your SDA eligibility requirements to understand the assessment process and evidence needed.

SIL Eligibility Requirements:

SIL funding eligibility is based on your need for ongoing support with daily living tasks. You need to demonstrate that you require assistance to live independently, whether that's a few hours per week or full-time support.

The NDIS will assess your current living situation, your goals for independent living, and the level of support you need to achieve those goals. They'll consider whether SIL support will help you build skills, maintain your independence, and participate in your community.

Unlike SDA, SIL eligibility isn't necessarily about the severity of your disability, but rather about your support needs for daily living activities.

Both SDA and SIL funding are included in your NDIS plan following an assessment by the NDIS planning team. Your support coordinator can help you understand whether you're likely to be eligible for either or both types of funding.

Can You Have Both SDA and SIL?

Yes, you can absolutely have both SDA and SIL funding in your NDIS plan. In fact, many people with disability receive both types of support.

Having both means you live in specialized, accessible housing (SDA) and receive daily living support from trained staff (SIL). This combination provides both the physical environment and the personal assistance needed for independent living.

For example, you might live in a Fully Accessible SDA home designed for wheelchair users, with ceiling hoists and roll-in showers. At the same time, you receive SIL support for meal preparation, personal care, and community participation.

The two types of funding complement each other perfectly. The accessible design of SDA housing makes it easier for support workers to provide effective assistance, while SIL support helps you make the most of your accessible home environment.

However, it's equally possible to have one without the other. You might receive SIL support in your family home or a standard rental property without needing SDA. Alternatively, you might live in SDA housing independently without requiring ongoing SIL support for daily tasks.

Your NDIS plan is individualized to your specific needs and goals. The combination of supports you receive - whether SDA, SIL, both, or neither - depends entirely on your circumstances and what will help you live the life you want.

How SDA and SIL Work Together: Real-Life Examples

Understanding how SDA and SIL work together in practice makes the distinction clearer.

Consider someone who uses a wheelchair and needs assistance with personal care and meal preparation. They might live in a High Physical Support SDA home with ceiling hoists and wheelchair-accessible design. Their SIL support workers visit twice daily to assist with morning routines, prepare meals, and help with evening personal care. The SDA provides the accessible environment, while SIL provides the hands-on support.

Another person might have intellectual disability and need support developing independent living skills. They could live in an Improved Liveability SDA home designed for sensory and cognitive needs. Their SIL support helps them learn meal planning, budgeting, and using public transport. Again, SDA provides the housing while SIL provides the skill-building support.

One of the most important considerations for families is staying connected to their support networks. We believe proximity to family matters most when choosing housing. Can your family live with you in SDA housing? The answer depends on your circumstances and whether Appendix H applies.

When SDA and SIL work together effectively, they support your independence while keeping you connected to the people and places that matter most. The accessible design of SDA removes physical barriers, while SIL support helps you build skills and confidence.

The key is ensuring both your housing and your support align with your goals, lifestyle, and the location that keeps you close to family and community.

Choosing Between SDA and SIL: Which Do You Need?

The decision about whether you need SDA, SIL, or both starts with understanding your current situation and goals.

Ask yourself these questions: What are the barriers to independent living in your current home? Do you need physical accessibility features, or do you need help with daily tasks? Could modifications to your current home address your needs, or do you need purpose-built accessible housing?

Consider your support needs separately from your housing needs. You might need SIL support regardless of where you live. Or you might need specialized housing design but be capable of managing daily tasks independently.

Your support coordinator plays a crucial role in helping you navigate these questions. They can assess your situation, discuss your goals, and help you understand which NDIS supports might be right for you.

The NDIS Specialist Disability Accommodation guidelines provide detailed information about SDA eligibility and assessment. The NDIS Supported Independent Living information explains SIL funding and how it works.

There's no one-size-fits-all answer. Your needs, goals, and circumstances are unique. The right combination of supports is whatever helps you live independently, stay connected to your community, and participate in the activities that matter to you.
