SDA vs Home Modifications: Which Does Your Situation Need?
SDA vs home modifications: what each funds, who qualifies, and how to decide whether to change your current home or move into specialist accommodation.
When your home no longer works for your body, the NDIS gives you two very different routes: change the home you already live in, or move into a purpose-built one. This guide explains what Specialist Disability Accommodation (SDA) and home modifications each fund, who qualifies for which, and how to work out which one your situation actually needs.

Frequently asked questions
Can I get both SDA and home modifications?
Usually not for the same home at the same time — they're alternative solutions. You might have modifications now and consider SDA later if your needs change, but the NDIS funds the most reasonable option for your situation, not both together.
Does the NDIS pay my rent in SDA?
No. SDA funds a contribution toward the specialist dwelling itself. You still pay a reasonable rent contribution and your everyday living costs, much as any tenant would.
Can I modify a rental property?
Yes, but the property owner must agree in writing before major modifications go ahead. Minor changes are often easier to arrange. Your OT report and a clear conversation with the owner both help.
Who decides which one I need?
An occupational therapist assesses your needs and home and recommends the most appropriate option. The NDIA then reviews the evidence against reasonable and necessary criteria before funding is included in your plan.
