SIL vs SDA: What Is the Difference Under the NDIS?
Specialist Disability Accommodation and Supported Independent Living are two separate parts of the National Disability Insurance Scheme. One covers the home you live in, and the other pays for the support workers who help you throughout the day. When you look at sda vs sil, you are looking at housing versus daily care.
Understanding how these budgets work makes planning your move or setting up your supports much clearer. You do not need both funding types to get help, and you do not need to move into an institution to receive daily assistance.
If you are new to this, start with our plain guide that explains what SIL is.
Key Takeaways
Specialist Disability Accommodation pays for the physical building under Capital Supports.
Supported Independent Living pays for your support workers under Core Supports.
Most participants who receive daily personal care live in regular houses or private rentals.
Housing contracts and care contracts stay separate, so you can change support teams without losing your lease.
What Is the Difference Between SIL and SDA?
The easiest way to understand this comparison is to picture the physical property as the where and your daily care as the how. Specialist housing acts like an accessible landlord, while daily support provides the team helping you cook, shower, and manage medication.
Your funding comes from two distinct budgets in your plan. Housing costs sit in your Capital Supports budget, while personal care comes from your Core supports budget under the Assistance with Daily Life category.
Specialist Disability Accommodation (SDA)
Sits in your Capital Supports budget under home modifications.
Pays for the land, architectural design, physical modifications, and structural repairs.
Requires clinical proof of extreme functional impairment or very high support needs.
Does not pay for support workers, food, or regular utility bills.
Operates through a standard residential tenancy agreement with a registered housing provider.
Supported Independent Living (SIL)
Sits in your Core Supports budget under Assistance with Daily Life.
Pays for support staff who help with showering, cooking, cleaning, and building everyday skills.
Requires evidence of significant daily support needs to live safely.
Does not pay for rent, property repairs, groceries, or power bills.
Operates through a service agreement directly with your care provider.
What Does Supported Independent Living (SIL) Fund?
Supported Independent Living focuses on hands-on assistance so you can live as independently as possible. Support workers help you complete personal tasks that you cannot manage safely on your own.
You receive funding based on your routine needs across the week. This support can happen in a shared house with other participants, or in a private home where you live on your own.
Daily Routines Covered by SIL
Personal grooming, including bathing, dressing, and oral care.
Menu planning, grocery shopping routines, and preparing meals.
House cleaning, laundry, and maintaining a hygienic living space.
Medication reminders, administration, and basic health tracking.
Overnight care, covering both active night shifts and sleepover shifts.
Living Costs That SIL Does Not Pay For
Weekly rent or mortgage installments.
Groceries, household goods, and personal shopping.
Utility accounts like electricity, gas, water, and home internet.
Entertainment, transport fuel, and personal hobbies.
How the NDIA Sets Your Roster of Care
Your funding amount depends on a document called a Roster of Care. This schedule maps out your weekly support requirements by the hour. It records when you need one-on-one help, when staff hours are shared with housemates, and what level of support you need through the night.
What Does Specialist Disability Accommodation (SDA) Fund?
When a participant has physical access requirements that standard houses cannot handle, the focus shifts to the building itself. Our article on whether the NDIS can help with housing covers other home and living options.
Specialist properties are purpose-built or modified to make mobility safe and simple. They include wide corridors, step-free access, and reinforced structures that allow people with severe functional impairments to move around freely.
The Four SDA Design Categories
The NDIA enrols housing under the SDA Design Standard across four categories:
Improved Liveability: Built for participants with sensory, intellectual, or cognitive impairments. Houses include visual contrast walls, clear doorways, and reduced sensory distractions.
Fully Accessible: Built for people who use wheelchairs or mobility aids. Dwellings feature step-free entries, wide doorways, accessible bathrooms, and lowered kitchen benches.
High Physical Support: Built for participants who need significant physical support. Homes include ceiling hoist tracks, automatic doors, emergency power backup systems, and assistive technology.
Robust: Built for participants with complex physical or behavioral needs. Properties use impact-resistant wall linings, secure retreat spaces, and sound dampening to protect residents.
The Reasonable Rent Contribution
Your plan pays the housing provider for the specialist property, but you must still pay for your basic room and board. This payment is called the Reasonable Rent Contribution.
The government sets a standard cap on this amount. You pay 25% of your basic Disability Support Pension, plus 100% of any Commonwealth Rent Assistance you receive. This system ensures your rent remains predictable while your plan covers the specialized building modifications.
Can You Receive SIL Without SDA (and Vice Versa)?
You can receive one of these supports without the other. They are entirely separate budgets and approvals.
Most people with daily support funding live in standard rentals, private properties, or family homes. If a regular house meets your physical requirements, you only need personal support funding to help with daily tasks.
Participants can also live in specialist properties without receiving traditional shared daily care. Some participants use drop-in support, family care, or individual arrangements instead of a shared support model. Because specialist housing requires proof of extreme functional impairment or very high support needs, many residents do use both services at the same time.
How SIL and SDA Work Together in Practice
When someone receives both supports, the property and the care team complement each other. The physical house provides safety and access, while the support staff help with daily routines.
Our supported independent living home in Balook shows how daily support and housing fit together in practice. Across Gippsland, Cardinia, and Pakenham, having local support workers nearby helps participants build life skills in calm, stable environments without moving away from their home region.
Your Right to Choose: Why the NDIS Separates Housing and Care
The NDIS Quality and Safeguards Commission requires housing providers and support providers to operate independently. This rule keeps control in your hands.
In older models, accommodation and care were often bundled into one contract. If a resident was unhappy with their carers, leaving meant giving up their home.
Today, you sign two separate contracts:
A residential tenancy agreement with your landlord or housing manager.
A service agreement with your daily support team.
If you ever want to change your support workers, you can switch providers without losing your room. You can also move to another house and bring your trusted support team with you.
Frequently Asked Questions About SIL vs SDA
Can I apply for both SIL and SDA at the same time?
Yes. If you have significant daily care needs and severe physical access barriers, you can apply for both home and living supports during your plan review.
Does SIL funding cover my electricity and groceries?
No. Daily support funding pays only for the workers who assist you. Food, utility bills, internet, and personal items are paid from your pension or personal income.
What assessments do I need for SDA approval?
You need formal clinical evidence. This evidence includes an Occupational Therapy housing assessment that documents your functional capacity and explains why standard housing cannot meet your physical needs.
What happens if my living needs change?
You can request a plan reassessment with the NDIA. Providing updated functional assessments will help align your funding with your current circumstances.
