How to read a SIL or SDA vacancy listing

Vacancy listings for supported independent living (SIL) and specialist disability accommodation (SDA) homes in Adelaide read like real estate ads written in NDIS code. "3+1, Robust, HPS, onsite SIL, RRC applies, available now." Each phrase carries a decision, and some of them are not obvious until after you have signed.

This guide decodes the common terms using the NDIS's own definitions, explains what you pay and what the plan pays, and lists where vacancies are published in South Australia. It is written for participants, families and support coordinators comparing listings before they enquire.

What "3+1 bedrooms" and the other shorthand means

"3+1" means three participant bedrooms plus one extra room for staff, usually described as an onsite overnight assistance (OOA) room or staff room. The NDIS SDA finder lists onsite overnight assistance as a dwelling feature, and the SDA pricing schedule prices dwellings differently depending on whether an OOA room exists. It means an overnight worker can stay in the house.

"2 of 3 available" tells you one person already lives there, so compatibility is already half decided. "Breakout room" is a separate space in a Robust home where a resident can withdraw safely; the SDA finder lists it as a feature too. "Available from" is the date the room can be occupied, not the date you can move in: a SIL quote, a service agreement and sometimes NDIA approval all have to happen first.

• SIL: funding for the support workers in the home. SDA: funding for the building. Many homes have both, some have only SIL (an ordinary rented house) and some SDA homes have no SIL attached.
• Ratio (1:1, 1:2, 1:3): how many participants share one worker, and the main driver of SIL cost.
• Active night versus sleepover: whether the overnight worker is awake and working, or sleeping on site and available if needed.
• MTA room or short stay: a temporary placement of up to 90 days or 14 days respectively, not a long-term vacancy.

SDA design categories, in plain terms

If a listing is SDA, it will name a design category. Your plan, if it includes SDA, names the category and building type the NDIA has agreed to fund, and the listing generally needs to match. The NDIS describes the four current categories as follows.

You will also see "Basic" and "Legacy Stock" in the SDA finder. These are older homes enrolled under earlier arrangements. They can be cheaper and are sometimes the only option in regional towns, but they do not carry the design features of the newer categories. Building type matters too: apartment, villa or townhouse, house or group home each attracts a different SDA payment, and your plan specifies which the NDIA will fund.

• Improved Liveability: better physical access and features for people with sensory, intellectual or cognitive impairments, such as walls and floors that are easy to see or living areas laid out so support workers can see you easily.
• Fully Accessible: a high level of physical access for people with significant physical disability, for example someone who uses a wheelchair at home.
• Robust: built strong and safe for the resident and others, with durable fittings that reduce repairs, suited to people who need help managing complex behaviours. Often paired with a breakout room.
• High Physical Support: high physical access plus features for very high support needs, such as ceiling hoists, backup power supply and home automation or communication technology.

Onsite SIL provider or bring your own support

Some listings say "onsite SIL provider" or "SIL provided by" a named organisation. In practice this means the organisation that runs the house, or has an arrangement with the SDA owner, delivers the 24-hour support, and moving in means choosing them as your SIL provider. Others say "bring your own supports" or "choice of SIL provider", meaning the housing is separate from the support and you, or the existing residents collectively, choose who provides it.

Neither model is wrong, but they trade off differently. An onsite provider gives one point of accountability for the house and the support, and often a faster move-in. A separated model gives you more leverage: you can change support provider without losing your home. SDA providers must be registered with the NDIS Commission, and since 1 July 2026 SIL providers must be registered too, so check both on the Commission's register whichever model applies.

In shared homes, support is shared across housemates under one roster, so a "bring your own" home in reality means the household chooses together. Ask how disagreements between housemates about the provider are resolved before you assume you could switch alone.

Rent, bills and the reasonable rent contribution

Your NDIS funding never pays your rent. In an SDA home you pay the provider a reasonable rent contribution (RRC). The NDIA's SDA guideline (3 September 2026) sets the maximum at 25 per cent of the Disability Support Pension, 25 per cent of the Pension Supplement, plus any Commonwealth Rent Assistance you receive. The amount should appear in your service agreement or in a separate rental agreement. If you choose a higher design category than your plan funds, a provider may ask for more rent, but must tell the NDIA within five business days and provide a property valuer's evidence that the extra is reasonable.

In a non-SDA SIL house you pay ordinary rent, usually set by the landlord or the head-lease holder, and should ask whether it is pitched at the RRC level or at market. Either way, ask what the figure includes. Utilities, internet, groceries and a contribution to shared household items are typically on top, and some providers bundle them as a weekly board amount. Get the breakdown in writing.

If a listing says "no rent" or "rent free", ask why. The NDIS Code of Conduct requires providers to act with honesty and transparency and to price fairly, and a clear rent figure separated from the support claim is the sign of a provider doing it properly.

Housemates, compatibility and support ratios

The most important information in a shared vacancy is rarely in the listing: who else lives there. Age range, gender, communication style, routines, noise tolerance, interests and the support ratio the household runs on all affect whether the home works. The SDA guideline confirms you can choose who you live with, that the provider needs to agree, and that the NDIA's decision about your SDA is separate from that choice.

Providers assess compatibility through a meeting, a shared meal or a short stay, and good ones involve the current residents. Ask how the household ratio is calculated: if your plan funds 1:3 daytime support and the home runs 1:2 because a housemate has higher needs, the roster has to reconcile that. Ask what happens if a housemate moves out and the ratio changes. The NDIS SIL guideline says a provider should not claim extra from your plan to cover vacancy periods, and that your service agreement and tenancy agreement should say how vacancies are managed.

Where vacancies are listed in South Australia

There is no single complete list. The NDIS SDA finder on ndis.gov.au is the official one for SDA-enrolled dwellings. It filters by state, building type, design category, number of residents, price per room and features such as onsite overnight assistance, but listing is voluntary and the NDIS says not all vacancies appear there. It does not cover non-SDA SIL houses.

Two national platforms list both: Housing Hub (housinghub.org.au), run by a registered charity, with a free housing advice line on 1300 61 64 63, and Nest (gonest.com.au), which lets you filter by SDA or non-SDA, SIL or other support funding, and short, medium or permanent stays. Both depend on providers choosing to list, so coverage of Adelaide and regional SA is uneven, and the NDIA does not endorse any third-party platform.

Provider websites remain the most current source, particularly for regional towns. ResicareSA publishes its current SIL, SDA, short term and medium term vacancies across Adelaide, the Yorke Peninsula, Whyalla, Port Augusta, the Riverland and the South East at /homes.

What to do next: questions to ask before you visit

A visit costs a day and raises hopes. Ask these by phone or email first, and compare the answers across listings.

The companion guide on questions to ask a SIL provider covers the service agreement and staffing detail once a home looks promising.

• Is the room SDA, and if so, which design category and building type? Does it match what my plan says?
• Who provides SIL in the house, and can that change without me moving out?
• What is the weekly rent, what does it include, and is it at the reasonable rent contribution?
• Who lives there now (age, gender, support needs in general terms, routines), and how do you assess compatibility?
• What support ratio does the house run on, day and night, and is the overnight worker awake or asleep?
• Is the room available now, and what has to happen between an offer and moving in?
• Is the provider registered for SIL, and for SDA if the home is SDA? Check the NDIS Commission register yourself as well.
• Can I do a short stay or a few shared meals before deciding?
