When families first encounter the NDIS housing system, they're often handed a list of acronyms, SDA, SIL, ILO, MTA, STA, without anyone explaining what any of them mean or which one actually applies to their situation. That's what this guide is for.

NDIS home and living supports are all the types of funding the National Disability Insurance Scheme (NDIS) can provide for where your family member lives and how they're supported at home. There are six types in total, and most families only need one or two of them, depending on their circumstances.

This post maps all six types in plain language and includes a decision framework to help you identify which ones may apply to your family member's situation. For deeper detail on any individual topic, we've linked to dedicated guides throughout.

What NDIS Home and Living Supports Are Available?

The NDIS uses "home and living supports" as an umbrella term for everything it can fund related to where someone lives and how they're supported at home. It's worth being clear about one thing upfront: the NDIS does not pay standard rent or mortgage costs. These supports are specifically for specialist housing design, support services, temporary accommodation, or modifications to existing housing.

Here are the six types:

SDA (Specialist Disability Accommodation) is purpose-built housing with specialist design features funded by the NDIS. It is for people with extreme functional impairment or very high support needs. SDA is about the physical dwelling, not the support inside it.

SIL (Supported Independent Living) funds support workers who assist with daily tasks like personal care, meals, and household management. SIL is about the people who support your family member, not the building they live in.

ILO (Individualised Living Option) is a flexible, participant-directed support arrangement. It lets your family member design their own support mix, including informal supports from family, paid workers, and community connections. More on this shortly.

Home modifications adapt existing housing with features like grab rails, ramps, and accessible bathrooms. These come from the Capital Supports budget.

STA (Short Term Accommodation) provides temporary housing and support for up to 14 days. It is most commonly used for respite, giving family carers a break.

MTA (Medium Term Accommodation) provides temporary housing for up to 90 days while your family member is waiting for permanent housing to be arranged. It is the one most families don't know exists until they need it.

These supports are not mutually exclusive. Many families access two or three of them simultaneously, particularly SDA and SIL together. For the official breakdown of what the NDIS funds for home and living, the NDIA's guidance page is the most current source.

SDA and SIL: Housing vs Support, Understanding the Difference

The single most important distinction in this whole system: SDA funds the building; SIL funds the support services inside it. These are separate line items in an NDIS plan, chosen and funded independently.

A person can have SDA without SIL, if they need specialist housing but can manage independently or with informal support from family. They can have SIL without SDA, if they need support services but can live in standard housing. Or they can have both, which is the most common arrangement for people with very high support needs.

Because each is funded separately, your family member also chooses their SDA provider and their SIL provider independently. They do not need to come from the same organisation. At Paramount, we provide SDA housing only. Your family member chooses their own support provider based on their needs and preferences.

SDA eligibility requires demonstrating extreme functional impairment or very high support needs. Not everyone who needs support services will qualify for SDA. For a detailed explanation of how SDA funding actually works, including the payment structure and eligibility assessment, our dedicated guide covers this thoroughly. Our SDA vs SIL guide goes deeper on the practical differences and how each appears in your plan.

If your family member's situation points toward SIL, the Supported Independent Living introduction covers eligibility, funding, and how to apply in detail.

ILO: The Flexible Option Many Families Haven't Heard Of

Individualised Living Options (ILO) is the least-known of the three main NDIS living support types, and that's genuinely not families' fault. It is underexplained in the system, and not all planners or support coordinators raise it proactively.

ILO is not about housing. It is a support package, not accommodation funding. The key distinction from SIL is that ILO is participant-led and highly flexible, where SIL tends to be more structured and is often associated with shared-living arrangements.

ILO suits your family member if they want to live in their own chosen home (a private rental, a family home, or a shared arrangement they have organised themselves) and design their own support mix. That mix might include informal support from family members, paid drop-in workers, and community connections, in whatever combination works for them.

Many families tell us they've never heard of ILO, and by the time they discover it, they've already been focused on SDA or SIL for months. Worth knowing: the NDIS funds an exploration phase for ILO before any commitment is made. This lets your family member and their coordinator investigate what an ILO arrangement could look like before formally applying.

ILO is worth asking about if your family member doesn't need SDA's specialist design features, wants more flexibility and self-direction than a shared SIL arrangement, and wants to direct their own support mix. Ask your support coordinator specifically about ILO if this sounds relevant.

Home Modifications, STA and MTA: The Supporting Cast

Three shorter explanations here, each for a support type that fits specific circumstances rather than being a primary housing solution.

Home modifications are funded under Capital Supports in your NDIS plan. They adapt existing housing with features like grab rails, ramps, widened doorways, accessible bathrooms, and in some cases ceiling hoists. They suit your family member if they can live in standard housing with adjustments. One practical note: if your family member is in a rental, landlord consent is required before modifications proceed.

STA (Short Term Accommodation) provides temporary housing and support for up to 14 days at a time. It is funded under Core Supports. STA is used for respite (giving family carers a break), trialling a more independent living arrangement, or emergency situations. It is not a housing solution, it is a temporary tool. Our complete guide to short-term accommodation and respite covers how STA works, what it includes, and how to access funding.

MTA (Medium Term Accommodation) is bridge housing for up to 90 days while your family member is waiting for their permanent housing to become available. The NDIS funds the accommodation but not support services during the stay. Crucially, MTA requires a confirmed permanent housing pathway before the NDIA will approve it. For families who have SDA funding approved but are waiting for a specific property to become available, MTA can bridge that gap. Most families don't know it exists until they're in exactly this situation.

Which NDIS Home and Living Support Applies to Your Family?

The honest answer is: for many families, more than one support may apply. The system is messier than any flowchart suggests. But these guiding questions can help you narrow it down.

Does your family member need specialist housing design features? Things like ceiling hoists throughout, reinforced construction, or a wheelchair-accessible layout designed from the ground up, not adapted from standard housing? If yes, explore SDA. If no, SDA is probably not the right pathway, even if your family member has significant disability.

Does your family member need daily support with personal care, household tasks, or meals? If yes, SIL or ILO applies. The distinction between them comes down to how much flexibility and self-direction your family member wants over their support arrangements. SIL tends to suit shared-living arrangements with structured rosters. ILO tends to suit people who want to live in their own chosen home and build a custom support mix.

Does your family member currently live in standard housing that could be improved with modifications? Home modifications may be the practical first step before considering any formal housing change. This option is often overlooked in favour of bigger solutions.

Is your family member in a temporary situation, such as leaving hospital or transitioning between homes, while waiting for permanent housing? MTA may bridge the gap if a permanent housing pathway is confirmed. STA may help if family carers need respite while this is sorted.

Working with a support coordinator is the most reliable way to navigate this. A good coordinator will assess your family member's situation and identify which supports to apply for. Don't rely on any single source, including this post, for a definitive answer about your family member's specific eligibility.

What to Do Next

NDIS home and living supports are not one-size-fits-all. Most families benefit from understanding all six types before committing to a single pathway. SDA, SIL, ILO, home modifications, STA, and MTA each exist for different circumstances, and some work together.

This is genuinely complex, and no blog post replaces a support coordinator's guidance for your specific situation. The official NDIS guidance on home and living covers what the NDIA can fund across all support types and is the definitive reference.

If SDA looks like it might apply to your family member, we'd love to help you understand your options. Our homes are located across Melbourne with one focus: keeping families close. Browse our available SDA homes or get in touch directly.
