SDA EXPLAINED

What is Specialist Disability Accommodation?

Specialist Disability Accommodation (SDA) is housing designed for NDIS participants with extreme functional impairment or very high support needs. SDA funding pays for the bricks and mortar — the building itself — separately from the day-to-day support a participant receives.

VISUAL GUIDE

Purpose-built homes, not modified stock.

Every SDA dwelling is designed from the ground up for accessibility, support delivery and long-term tenancy — with features that standard housing cannot reasonably provide.

SDA vs SIL — what's the difference?

SDA funds the home — the specialist building itself. It is paid to the SDA provider (like Indus Ability) by the NDIA.

SIL (Supported Independent Living) funds the support workers who help with daily living. It is paid to the SIL provider — which the participant chooses, and can change, without affecting their tenancy.

Keeping the two separate protects the participant: your home is not tied to your support provider.

DESIGN CATEGORIES

Every SDA dwelling is enrolled with the NDIA against one design category. The category drives both the design and the SDA payment level.
