Specialist Disability Accommodation cost in Australia typically ranges from $5,000 to over $114,000 per participant per year, depending on the housing type, design category, and location. In most cases, the National Disability Insurance Scheme (NDIS) covers the majority of this cost, with participants only contributing a capped rent amount.
Quick Answer: SDA Cost in Australia
- Annual Cost Range: $5,000 – $114,000+ per participant
- Who Pays: Mostly covered by NDIS funding
- Participant Contribution: Capped rent (MRRC)
- Extra Costs: Optional (meals, utilities, premium housing choices)
What Is Specialist Disability Accommodation (SDA)?
Specialist Disability Accommodation (SDA) refers to purpose-built housing designed for people with extreme functional impairment or very high support needs.
These homes go beyond standard housing and include:
- Wheelchair-accessible layouts
- Ceiling hoists and assistive technology integration
- Reinforced structures for safety (Robust category)
- On-site support provisions
Because of the complexity and cost of these builds, SDA is funded separately by the NDIA.
Who Is Eligible for SDA Funding?
SDA is highly targeted—only around 6% of NDIS participants qualify.
To be eligible, you must:
- Be an active NDIS participant (generally aged 7+)
- Have a permanent disability
- Require specialised housing due to extreme functional impairment
- Prove standard housing is unsafe or unsuitable
Once approved, SDA eligibility funding is included in your NDIS plan based on your housing needs.
Who Pays for SDA?
The NDIS pays SDA providers directly on behalf of participants.
What You Pay: MRRC (Capped Rent)
As a participant, you contribute a Maximum Reasonable Rent Contribution (MRRC), which is linked to your Disability Support Pension.
From September 2025:
- $506.56 per fortnight (own room)
- $320.98 per fortnight (shared room)
This is typically your only mandatory housing cost.
Can You Pay More for SDA?
Yes—but only under specific conditions.
You may pay extra if:
- You choose a higher-cost property than your funding covers
- The provider has approval and valuation certification
Optional costs include:
- Meals and utilities (board payments)
- Premium housing upgrades
These must always be clearly outlined in your service agreement.
What Factors Affect SDA Cost?
SDA pricing is not fixed—it varies based on five key factors:
1. Building Type
Different housing types come with different price limits:
- Apartments (1–3 residents)
- Villas, duplexes, townhouses
- Houses (shared living)
- Group homes (4–5 residents)
- Legacy stock (older facilities)
Smaller, private dwellings generally cost more per participant.
2. Design Category
There are five SDA design categories:
- Basic – Minimal modifications
- Improved Liveability – For cognitive or sensory needs
- Fully Accessible – High physical accessibility
- Robust – Designed for safety and durability
- High Physical Support – Advanced care infrastructure
Higher support needs = higher funding.
3. New Build vs Existing Housing
- New Builds (Post-2023): Highest funding (modern standards)
- Existing Stock: Moderate funding
- Legacy Stock: Lowest funding
New builds attract premium pricing due to compliance and design standards.
4. Location
SDA pricing varies by region using location multipliers.
- High-cost areas (e.g., inner-city Sydney): significantly higher funding
- Regional/remote areas: adjusted for service delivery costs
Location can nearly double the funding in some cases.
5. Additional Features (OOA & Modifications)
Extra funding applies if the property includes:
- On-Site Overnight Assistance (OOA) room
- Breakout rooms (Robust category)
- Fire sprinkler systems
SDA Pricing Table (2025–26)
Below are indicative annual base prices per participant for new builds:
| Building Type | Improved Liveability | Fully Accessible | High Physical Support |
| Apartment (1 bed) | $77,834 | $80,262 | $87,235 |
| Apartment (2 bed) | $35,151 | $36,007 | $39,654 |
| House (2 residents) | $64,810 | $66,514 | $78,171 |
| Group Home (5 residents) | $31,341 | $32,622 | $38,132 |
With OOA, High Physical Support apartments can exceed $100,000 per year.
Legacy group homes can be as low as $10,000 per participant annually.
Real Example: SDA Cost Breakdown
A participant in a high-support apartment may receive:
- Base SDA funding: ~$87,000/year
- OOA support: +$13,000
- Location factor increase: +30–80%
Final SDA funding can exceed $120,000 annually, fully covered by the NDIS (excluding rent contribution).
How Shared Living Affects SDA Cost
Sharing reduces cost per participant:
- Shared bedroom: ~50% funding each
- Shared home with non-SDA residents: reduced pricing
- Larger group homes: lower per-person cost
This ensures fair and proportional funding.
SDA vs Standard Housing Costs
| Type | Who Pays | Cost Level |
| SDA | NDIS (mostly) | Low out-of-pocket |
| Private Rental | Individual | High |
| Social Housing | Government | Limited availability |
SDA is significantly more affordable for eligible participants.
