SDA and NDIS info

What is SDA?​

Specialist Disability Accommodation (SDA) is purpose-built NDIS-funded housing for participants with extreme functional impairment or very high support needs. SDA funding pays for the physical home its accessible design, assistive technology, and safety features not the day-to-day support delivered inside it, which is funded separately through Supported Independent Living (SIL).
The NDIS SDA Design Standard defines four SDA design categories:
  • Improved Liveability – Designed for people with sensory, intellectual, or cognitive impairment.
  • Fully Accessible – Wheelchair-friendly homes with enhanced accessibility features.
  • Robust – Designed for participants requiring resilient construction and low-stimulation environments.
  • High Physical Support – Homes with advanced accessibility features such as ceiling hoists, emergency backup power, and assistive technology.
SDA Homes WA is an NDIS-registered provider offering Specialist Disability Accommodation across Perth’s southern and eastern suburbs.

How does SDA funding work ?

SDA funding is included in an eligible participant’s NDIS plan as a specific support category, separate from SIL and other daily support funding. To access SDA, the NDIA must assess a participant against extreme functional impairment or very high support needs criteria and approve SDA funding within their plan. Once approved, that funding follows the participant to whichever registered SDA home they choose it does not pay for support workers, personal care, or day-to-day assistance, which is funded separately through SIL.

Which NDIS Housing Support Is Right for You?

SDA is often confused with Supported Independent Living (SIL), Short Term Accommodation (STA), Medium Term Accommodation (MTA), and Individualised Living Options (ILO). Each support serves a different purpose within the NDIS. Explore our detailed comparison to understand what each option covers, who it’s designed for, and when it may be the right choice.

Who Is Eligible for Specialist Disability Accommodation (SDA)?

To be eligible for Specialist Disability Accommodation (SDA), you must be an NDIS participant whose plan includes SDA funding. The National Disability Insurance Agency (NDIA) assesses eligibility based on whether you have an extreme functional impairment or very high support needs that require specialised housing.

SDA is generally suitable for participants who:

  • Need significant physical support to live safely and independently.
  • Have complex behavioural support needs.
  • Require an accessible home with specialised design features.
  • Cannot safely live in standard housing without major modifications or ongoing support.

If you’re unsure whether you meet the SDA eligibility criteria, our team can help you understand the assessment process and discuss suitable housing options with your support coordinator.

FAQs

What is Specialist Disability Accommodation (SDA)?

Specialist Disability Accommodation (SDA) is NDIS-funded housing designed for people with extreme functional impairment or very high support needs. SDA funding covers the specialised home itself, including accessible design and safety features. It does not pay for daily support services, which are funded separately through supports such as Supported Independent Living (SIL).

You may be eligible for SDA if you are an NDIS participant with an approved SDA budget in your plan. Eligibility is based on evidence that you have extreme functional impairment or very high support needs and require specialist housing to live safely and independently.

SDA refers to the physical home, including accessible design features and specialist construction. SIL (Supported Independent Living) provides daily support services such as personal care, meal preparation, and household assistance. Many participants receive both supports, but they are funded separately through the NDIS.

Each category is designed to meet different functional needs, from improved accessibility to complex physical or behavioural support requirements.
