What Is Specialist Disability Accommodation (SDA)? 2026 Eligibility & Funding Guide for Perth
If you or someone in your family has significant disability-related support needs and your current housing is no longer meeting those needs, Specialist Disability Accommodation (SDA) may be one of the most important NDIS supports you can access. Yet for many Perth families, SDA remains one of the least understood — and most underutilised — parts of the scheme.
This guide was written to change that. Whether you are a participant exploring your options for the first time, a family member researching on behalf of a loved one, or a support coordinator trying to explain SDA to a client, this 2026-updated guide covers everything you need to know: what SDA is, who qualifies, what the four design categories mean in practice, and how to access SDA housing in Perth.

What Is Specialist Disability Accommodation (SDA)?
Specialist Disability Accommodation (SDA) is a category of NDIS funding that covers the cost of purpose-built or modified housing for people with very high support needs or extreme functional impairment. It is one of the most significant — and most misunderstood — funding streams within the National Disability Insurance Scheme.
It is important to understand from the outset what SDA does and does not fund. SDA funding covers the physical housing itself — the bricks, mortar, and specialist design features that make the property accessible and suitable for a person with high support needs. It does not fund the support workers who assist you inside that home. The support workers are funded separately through Supported Independent Living (SIL) or other daily support budgets within your NDIS plan.
For more on how SIL works alongside SDA, see our guide to Supported Independent Living (SIL) in Perth — or explore our full range of
NDIS disability accommodation options to understand how the different accommodation types work together.
What Are the Four SDA Design Categories?
One of the most frequently misunderstood aspects of SDA is the design category system. There are four SDA design categories, each reflecting a different level of accessibility and specialisation. Understanding which category applies to your needs is essential for finding the right property and ensuring your NDIS plan is funded at the appropriate level.
Improved Liveability
Improved Liveability homes are designed for people with sensory, intellectual, or cognitive impairment. These properties include features that improve ease of living — such as improved lighting, more defined spaces, and reduced sensory triggers — but do not require the heavy structural modifications of higher-category properties. This is the most commonly available SDA design category.
Fully Accessible
Fully Accessible properties are built to high physical access standards for people with significant physical impairment. Features typically include wheelchair-accessible bathrooms with turning circles, height-adjustable benches, wider doorways and corridors, and step-free entry throughout the property. This category suits participants who use a wheelchair or other mobility aids as a primary means of moving through their home.
High Physical Support
High Physical Support properties are built for participants with the most significant physical support needs — typically those who require ceiling hoists, specialised bathroom equipment, or overnight on-site support. These homes include robust structural features such as reinforced ceilings for hoist tracks, emergency power systems, and technology-assisted environments. This is the most specialised and most expensive category of SDA housing to build and fund.
Robust
Robust properties are designed for participants who may exhibit behaviours that pose a risk to themselves or to the physical integrity of their home environment. These properties are built with strengthened surfaces, impact-resistant materials, and design features that reduce the risk of injury and property damage. Robust properties often include additional security features and are typically smaller in scale to enable close supervision.
What Types of SDA Housing Are Available in Perth?
SDA housing in Perth comes in several dwelling types, each suited to different living preferences and support needs. Understanding the available dwelling types helps participants and families make more informed decisions when searching for an appropriate property.
Apartments and units are increasingly common in Perth’s SDA housing market, particularly in newer purpose-built developments. These offer participants independence and privacy within a secure building, often with shared communal areas. Group homes — smaller residential properties accommodating two to five participants — remain widely available and suit people who prefer or need a smaller community environment with on-site support readily accessible.
Larger, purpose-built residential facilities accommodate participants with more intensive support needs and typically include on-site support worker facilities. Villas and townhouses provide a more typical residential experience and are often suitable for participants with Improved Liveability or Fully Accessible needs. Finally, custom or individual dwellings can be funded for participants whose needs cannot be met by any existing SDA property — these are less common and require a higher level of evidence to justify.

How Do You Apply for SDA Funding in Perth? Step by Step
Applying for SDA funding is a multi-step process that requires careful preparation, particularly around the quality of functional evidence you provide. The following steps reflect current NDIA practice for SDA applications in Western Australia in 2026.
Step 1: Confirm You Meet the Broad Eligibility Criteria
Before investing significant time and resources in a formal SDA application, speak with your support coordinator, Local Area Coordinator (LAC), or a registered NDIS provider to assess whether your needs are likely to meet the SDA eligibility threshold. This initial conversation helps you understand whether gathering formal evidence is likely to lead to a successful outcome.
Step 2: Commission a Functional Capacity Assessment
The most important document in an SDA application is a Functional Capacity Assessment from a qualified Occupational Therapist (OT). This assessment must clearly demonstrate that your current housing is not meeting your needs, that your functional impairment is permanent and significant, and that purpose-built SDA housing would provide material benefits to your safety, independence, or long-term outcomes.
Step 3: Gather Supporting Evidence
In addition to the OT assessment, your application should be supported by reports from treating specialists, your GP, and any other health professionals involved in your care. These reports should focus on functional impact — how your condition affects your daily ability to live safely at home — rather than providing a clinical summary of your diagnosis.
Step 4: Raise SDA at Your Plan Review
SDA funding is approved through your NDIS plan review. Present your functional evidence to your NDIA planner or LAC at your next scheduled review, or request an unscheduled review if your housing situation has significantly changed. Be clear and specific about your housing needs and the design features your situation requires.
Step 5: Choose an SDA Registered Provider
Once SDA funding is included in your plan, you can begin searching for appropriate SDA properties. All SDA providers must be registered with the NDIA, and all SDA dwellings must be registered on the NDIS SDA register. Innovative Disability Services is a registered NDIS provider offering SDA housing across Perth metro.

Frequently Asked Questions
SDA funding is available to NDIS participants with extreme functional impairment or very high support needs that cannot be met in standard housing. Eligibility is assessed based on functional impact, not diagnosis. Only around 6% of NDIS participants are expected to require SDA funding, so evidence quality is critical.
Begin by speaking with your support coordinator or a registered NDIS provider. Commission a Functional Capacity Assessment from an Occupational Therapist, gather supporting specialist reports, and raise SDA at your next NDIS plan review. The quality of your functional evidence is the primary determinant of approval.
Timelines vary depending on the completeness of your evidence and NDIA processing times. After submitting supporting evidence at a plan review, decisions can take several weeks to months. During this period, Medium Term Accommodation (MTA) can provide interim housing if needed.
MTA provides interim housing for NDIS participants who are waiting for their long-term SDA placement to become available. It is typically funded for up to 90 days. Learn more on our Medium Term Accommodation page.
