What is SDA? Specialist Disability Accommodation (SDA) is a type of NDIS-funded housing designed for people with extreme functional impairment or very high support needs. It is the home itself, purpose-built with features like wheelchair access, ceiling hoists or reinforced walls, rather than the support workers who help you day to day. This guide explains, in plain English, who SDA is for, the four design categories, how the funding works, and how SDA is different from SIL.
Quick summary
- SDA is specialist housing, not a support service. It is the building, designed around your disability needs.
- It is for people with extreme functional impairment or very high support needs.
- There are four SDA design categories: Improved Liveability, Fully Accessible, Robust, and High Physical Support.
- SDA is usually paired with other funding, such as Supported Independent Living (SIL), which pays for your support workers.
- SDA funding pays the housing provider. You pay a reasonable rent contribution and your everyday bills.
- SDA homes must be enrolled by a provider registered with the NDIS Quality and Safeguards Commission.
What is SDA, exactly?
Specialist Disability Accommodation is a range of housing funded through the NDIS for people whose disability needs cannot be met by other home and living supports. According to the NDIS, it is designed for people with extreme functional impairment or very high support needs.
The key thing to understand is that SDA is the home, not the help. It is housing built or modified with features that meet your disability support needs. Those features might include wide doorways, wheelchair-accessible kitchen sinks, ceiling hoists, or button-operated doors. An SDA property can be a house, apartment, villa, duplex or townhouse.
What SDA does not include is just as important. It does not cover personal care, Supported Independent Living (SIL), individualised living options, or assistive technology. Those supports are funded separately. SDA pays for the specialist dwelling; other funding pays for the people and services that support you inside it.
The four SDA design categories
SDA is categorised by how a home is built to suit different disability needs. There are four official design categories. The right one for you depends on your individual needs and what is written into your NDIS plan.
| Design category | Who it is designed for |
|---|---|
| Improved Liveability | Better physical access and more features for people with sensory, intellectual or cognitive impairments. For example, walls and floors that are very easy to see, or living areas where support workers can see you easily. |
| Fully Accessible | A high level of physical access features for people with significant physical challenges. For example, if you need to use a wheelchair at home. |
| Robust | Housing built to be safe, strong and durable, reducing the need for repairs and maintenance. This category may suit people who need help managing complex behaviours. |
| High Physical Support | A high level of physical access for people who need very high levels of support. For example, ceiling hoists, backup power supply, or home automation and communication technology. |
Who is SDA for?
SDA is not for everyone on the NDIS. It is a specialist support for a smaller group of participants whose disability means everyday housing simply does not work for them. The NDIS looks at whether SDA is reasonable and necessary for you, how it works alongside your other supports, and whether it meets the funding criteria.
The goal of SDA is to help you live more independently and to allow your other supports to be delivered more safely. For example, a home with reinforced ceilings means a ceiling hoist can be installed so your support workers can help you transfer safely. Whether SDA is included in your plan is a decision made with the NDIS, usually with input from your support coordinator and allied health professionals.
How does SDA funding work?
SDA funding sits separately from the funding for your support workers. It helps to see how the three pieces fit together:
- SDA funding pays your SDA provider for the specialist home.
- SIL funding (or other in-home support funding) pays for your carers and support workers.
- You pay a reasonable rent contribution and your day-to-day living costs, such as electricity.
Your rent contribution is an agreed amount paid directly to your SDA provider, and it should be set out in a written service agreement. The amount a provider can charge you cannot exceed the maximum reasonable rent contribution, which is set out in the NDIS pricing arrangements. We have not listed dollar figures here on purpose, because they are set by the NDIS and change over time. Always check the current figures on the NDIS website or with your provider.
SDA vs SIL: what is the difference?
This is the question most families ask, because the two almost always go together. The simplest way to remember it:
- SDA is the home. The specialist building, funded to the housing provider.
- SIL is the support. The day-to-day help from support workers, funded to the support provider.
Many participants who live in SDA also receive SIL funding for the workers who support them at home. One pays for the bricks and features; the other pays for the people. You can read more on our Supported Independent Living page.
How do you find an SDA home?
If you have SDA funding in your plan, there are a few ways to find a home:
- Use the NDIS SDA finder to search by location, building type and price.
- Ask your support coordinator or recovery coach for a referral.
- Get recommendations from friends, family, or trusted online resources.
- Contact SDA providers directly to ask about their available homes.
Once you find a home, you and your provider must have a written service agreement, and you need to record your SDA provider on your NDIS plan. If you are looking in Western Sydney or regional New South Wales, you can browse our current SIL and SDA vacancies.
Frequently asked questions
What does SDA stand for?
SDA stands for Specialist Disability Accommodation. It is a type of NDIS-funded housing designed with features that meet the needs of people with extreme functional impairment or very high support needs.
Is SDA the same as SIL?
No. SDA is the specialist home, funded to the housing provider. SIL (Supported Independent Living) is the day-to-day support from workers, funded separately. Many people have both, but they are different things.
Who is eligible for SDA?
SDA is for a smaller group of participants with extreme functional impairment or very high support needs, where other home and living supports do not meet the need. Eligibility is decided with the NDIS as part of your plan, based on whether SDA is reasonable and necessary for you.
Do I pay rent in an SDA home?
Yes. SDA funding pays your provider for the home, but you still pay a reasonable rent contribution and your everyday bills, such as electricity. The rent amount is capped by the NDIS and should be written into your service agreement.
What are the four SDA design categories?
Improved Liveability, Fully Accessible, Robust, and High Physical Support. Each is built to suit a different level and type of disability need, from sensory and cognitive support through to very high physical support.
Can I live alone in SDA?
SDA often involves sharing a home with a small number of other people, where you have your own private bedroom. Sometimes participants may be able to live on their own if that is the best option for their needs.
How do I get SDA added to my NDIS plan?
SDA is included through your NDIS planning process, usually with input from your support coordinator and allied health professionals who can provide evidence of your housing needs. Speak to your my NDIS contact to learn how to ask for home and living supports.
