Frequently asked questions
Is SDA the same as having support workers in my home?
No. SDA pays for the specially designed home itself — the accessible bathroom, hoists, wider doors and so on. The support workers who help you day to day are funded separately, usually through Supported Independent Living (SIL) or another arrangement. You can often choose your home and your support provider separately.
Do I still pay rent if I live in SDA?
Yes. SDA funding covers the specialist building costs, but you still make a Reasonable Rent Contribution, generally set at 25% of the Disability Support Pension plus any Commonwealth Rent Assistance. You also pay your own everyday costs like electricity and food. Confirm the exact figures with the NDIA and the provider, as rates change.
How do I know which SDA design category I need?
The category is based on your needs, and an occupational therapist housing report usually recommends the right one — Improved Liveability, Fully Accessible, Robust, or High Physical Support. If SDA is approved, your plan will name the category you are funded for. The categories match different needs rather than ranking people.
Will the NDIS reforms take away my SDA?
SDA is capital housing support, and the social and community participation budget reset that begins from 1 October 2026 does not target housing or personal care. Larger changes to planning and eligibility roll out from 2027 and 2028, and existing participants are reassessed as plans renew. Anyone with significant ongoing needs should continue to qualify, but confirm current rules and dates with the NDIA.
What if my SDA request is knocked back?
You can ask for a review of the decision. Make sure your housing goal and occupational therapist evidence are strong, as these are the most common gaps. Extra appeals and advocacy funding was made available in 2026-27 through Legal Aid and NDIS appeals to help people challenge decisions at the Administrative Review Tribunal.
