Frequently asked questions
Do I need to be a registered NDIS provider to offer SDA?
Yes. SDA cannot be delivered by unregistered providers. You must register your organisation with the NDIS Quality and Safeguards Commission for the Specialist Disability Accommodation registration group and pass the required audit against the NDIS Practice Standards, including the SDA module. Separately, each dwelling must be enrolled with the NDIA before you can claim. Confirm the current audit pathway with ndiscommission.gov.au.
What is the difference between SDA and SIL?
SDA funds the physical dwelling — the specialist housing. SIL funds the support workers who help the resident with daily living inside that home. They are funded and claimed separately, and are often best delivered by separate organisations so a resident can change support providers without losing their home. You can be an SDA provider without employing any support staff.
How much does an SDA provider get paid?
Two streams: the SDA price, an annual capital amount set in the NDIA's SDA Pricing Arrangements and claimed per enrolled, occupied place; and the Reasonable Rent Contribution paid by the resident, commonly 25% of the Disability Support Pension plus Commonwealth Rent Assistance. Prices vary widely by design category, building type, location and resident numbers. Confirm exact figures in the current SDA Pricing Arrangements — you are paid the SDA price only while an eligible participant is living there and claiming.
Can an existing house be enrolled as SDA?
Sometimes, but it must be certified by an accredited SDA assessor against the applicable SDA Design Standard, and existing stock rarely meets the higher categories like High Physical Support without significant modification. Legacy and transitional dwellings may attract different, generally lower, price treatment than new builds. Get an assessor to review the property before you assume it will enrol or at what category.
What is the biggest risk in becoming an SDA provider?
Vacancy. Your tenant pool is small and specific to your dwelling's design category and location, and you earn SDA only while an eligible participant is living there. A dwelling can sit enrolled and empty for months while you carry the full mortgage and holding costs. Model realistic occupancy, including a lease-up period and turnover voids, rather than the near-full occupancy that marketed yields assume.
