Many NDIS participants find themselves confused by two similar-sounding supports in their plans: SDA and SIL. While both relate to housing and independence, they serve very different purposes and fund completely different things. Understanding the distinction between Specialist Disability Accommodation (SDA) and Supported Independent Living (SIL) is essential for making informed decisions about your housing and support needs.
This guide breaks down exactly what each support covers, who qualifies for them, and how they can work together to create the right living arrangement for your needs in Perth and across Western Australia.
What is SDA (Specialist Disability Accommodation)?
SDA funding covers the bricks and mortar of specially designed housing. Think of SDA as paying for the physical building itself, specifically properties that have been purpose-built or significantly modified to meet the needs of people with disability.
SDA properties include features like:
- Wheelchair accessible bathrooms and kitchens
- Wider doorways and corridors
- Ceiling hoists and tracking systems
- Smart home technology integration points
- Emergency response systems
- Accessible outdoor areas and parking
The NDIS recognises four main SDA design categories, each targeting different support needs. SDA design categories explained covers these in detail, but they range from Improved Liveability (basic accessibility features) through to High Physical Support (extensive modifications for people with complex physical needs).
SDA funding appears as a separate line item in your NDIS plan and is paid directly to your SDA provider. You don't handle this money yourself. The amount depends on your assessed needs, the design category you require, and the location of the property.
In Perth, SDA properties are becoming more available across suburbs like Joondalup, Rockingham, and Midland, with new developments regularly coming online to meet growing demand.
What is SIL (Supported Independent Living)?
SIL funding covers the human support you need to live independently in your home. This includes assistance with daily tasks, personal care, household management, and community participation. SIL is about the people who help you, not the building you live in.
SIL supports typically include:
- Personal care assistance (showering, dressing, medication management)
- Household tasks (cooking, cleaning, shopping)
- Community access support
- Skills development and training
- 24/7 support if required
- Emergency response and safety monitoring
SIL can be provided in various settings, including your own home, a group home, or an SDA property. The level of support ranges from a few hours per week to 24/7 assistance, depending on your assessed needs.
Unlike SDA, SIL funding goes into your plan as capacity building or core supports budget. You have more control over how this funding is used and can often choose your support provider.
Key differences between SDA and SIL
The fundamental difference lies in what each support funds:
| Aspect | SDA | SIL | |--------|-----|-----| | What it covers | The building and its accessibility features | Human support and assistance | | Payment method | Paid directly to property provider | Managed through your plan budget | | Eligibility | Strict criteria, requires specific assessments | Broader eligibility based on support needs | | Your control | Limited choice in modifications | More flexibility in support arrangements | | Duration | Ongoing while you live there | Can be adjusted at plan reviews |
You might qualify for one, both, or neither of these supports. Each has its own assessment process and eligibility criteria.
Who qualifies for SDA funding?
SDA eligibility is quite strict. You must demonstrate that you have an extreme functional impairment or very high support needs that require specially designed accommodation. The NDIS estimates that only about 6% of participants will qualify for SDA funding.
SDA eligibility explained covers the detailed criteria, but generally you need to show that:
- Standard housing cannot meet your needs, even with modifications
- You require specific design features due to your disability
- SDA represents value for money compared to alternatives
- You have the capacity to live independently with appropriate supports
The assessment process involves detailed reports from occupational therapists, medical specialists, and other allied health professionals. These reports must clearly demonstrate why standard housing is unsuitable and how SDA features will improve your independence and quality of life.
Who qualifies for SIL funding?
SIL eligibility is broader than SDA. You may qualify if you need regular assistance with daily living activities and this support will help you live more independently.
Common situations where SIL funding is approved include:
- Needing help with personal care tasks
- Requiring supervision for safety reasons
- Needing assistance to participate in community activities
- Having difficulty managing household tasks independently
- Requiring support to develop independent living skills
The key is demonstrating that the support is necessary for your independence and wellbeing, and that it represents reasonable and necessary funding under the NDIS.
How SDA and SIL work together
While SDA and SIL are separate supports, they often complement each other perfectly. Many people living in SDA properties also receive SIL funding to help them make the most of their accessible accommodation.
For example, someone with high physical support needs might live in an SDA property with ceiling hoists and accessible bathrooms, while receiving SIL funding for personal care assistance and help with daily tasks. The SDA provides the physical environment they need, while SIL provides the human support.
This combination allows people with significant disabilities to live independently in the community rather than in institutional settings. Living independently with high physical support needs explores how this works in practice for Perth residents.
The smart home technology often integrated into SDA properties can also reduce the amount of SIL support needed. Automated systems for lighting, climate control, and security can help people manage their environment independently, potentially reducing support hours and costs.
Finding the right combination in Perth
Perth offers growing options for both SDA and SIL supports. When looking for the right combination, consider:
Location factors: Proximity to family, medical services, public transport, and community facilities. Perth's northern and southern corridors offer good access to services and transport links.
Provider choice: Different SDA providers offer varying levels of technology integration and design quality. SIL providers also vary in their service models and specialisations.
Future planning: Consider how your needs might change over time. Some SDA properties offer flexibility to adjust technology and modifications as needs evolve.

Costs and funding considerations
Understanding the costs involved helps you plan effectively:
SDA costs vary significantly based on design category, location, and property features. In Perth, weekly SDA payments can range from around $500 for Improved Liveability properties to over $2,000 for High Physical Support accommodation.
SIL costs depend on the level and type of support needed. This might range from a few thousand dollars annually for minimal support to over $200,000 yearly for 24/7 assistance.
Budgeting for smart home technology explains how to factor technology costs into your planning, whether funded through SDA, assistive technology, or home modifications budgets.
Making informed decisions
Choosing between SDA, SIL, or both requires careful consideration of your current and future needs. Key questions to ask include:
- Can your current housing be modified to meet your needs?
- What level of daily support do you require?
- How important is location and community connection?
- What are your long-term housing goals?
- How might your needs change over time?
Working with experienced occupational therapists and support coordinators helps ensure you understand all your options. They can assess your needs, explain eligibility requirements, and help you make informed decisions about your housing and support arrangements.
Getting started with your housing journey
Whether you're exploring SDA, SIL, or both supports, the first step is understanding your options and eligibility. Start by discussing your housing goals with your support coordinator or occupational therapist. They can help assess your needs and guide you through the application process.
If you're considering SDA in Perth, take time to visit different properties and understand what each design category offers. For SIL, research different provider models to find the support style that best matches your preferences and goals.
