Reasonable Rent Contribution in SDA: what you pay explained

By The Find My SDA Team · Updated 10 Aug 2026

SDA funding pays for the specially designed home, but most residents also pay something towards living there, called a Reasonable Rent Contribution, or RRC. It is a common source of confusion, so this guide explains what the RRC is, how it is generally calculated, and what it does not cover. For the bigger picture of what SDA funding pays for, see how SDA funding works.

What the Reasonable Rent Contribution is

The Reasonable Rent Contribution is the amount an SDA resident pays towards their accommodation from their own income, on top of the SDA funding in their NDIS plan. It is the resident's contribution to the cost of the home, similar in spirit to rent, and it is set out in the residency or SDA agreement for the home.

The RRC is separate from your NDIS funding. Your SDA funding goes to the provider for the dwelling; the RRC comes from your income.

How the RRC is commonly worked out

Under the NDIS Pricing Arrangements for SDA, the maximum a provider can ask a single resident who does not share a bedroom to pay is 25% of the maximum basic rate of the Disability Support Pension, plus 25% of the maximum rate of the Pension Supplement, plus 100% of the maximum rate of Commonwealth Rent Assistance. This cap is called the Maximum Reasonable Rent Contribution, and it is set by the NDIS, not by individual providers. You can read the current rules and figures on the NDIS SDA pricing arrangements page.

Because it is based on pension and rent assistance rates, which the Australian Government indexes periodically, the exact dollar figure changes over time and can vary with a resident's circumstances. The precise amount for a particular home should always be confirmed in writing before moving in, and the current figures should be checked on the NDIS website.

What the RRC does not cover

The RRC is for the accommodation only. It does not pay for the support you receive at home, such as Supported Independent Living, which is funded separately in your plan.

It also does not usually cover everyday living costs such as electricity, gas, water, internet, food or contents insurance. Residents generally pay for their own utilities and day-to-day expenses, just as they would in any home. Check the residency agreement for exactly what is and is not included.

Confirm the numbers before you move in

Before accepting an SDA home, ask for the Reasonable Rent Contribution and any other regular costs in writing, and check them against your income. A good provider will explain the RRC clearly and put it in the agreement.

When you enquire through Find My SDA, we can talk through the accommodation costs for a specific home and how they sit alongside your SDA funding. If you are weighing up providers, our guide on how to choose an SDA provider may help.

Common questions

How much is the Reasonable Rent Contribution?

Under the NDIS Pricing Arrangements for SDA, the maximum for a single resident who does not share a bedroom is 25% of the Disability Support Pension, plus 25% of the Pension Supplement, plus 100% of Commonwealth Rent Assistance. Because those payments are indexed and change over time, the exact amount varies and should be confirmed in writing for each home.

Is the Reasonable Rent Contribution the same as my NDIS funding?

No. Your NDIS SDA funding pays the provider for the dwelling. The Reasonable Rent Contribution is a separate amount you pay towards the home from your own income.

Does the Reasonable Rent Contribution cover my support or bills?

No. It is for the accommodation only. Support such as Supported Independent Living is funded separately, and residents usually pay their own utilities and everyday living costs.

This guide is general information only, not financial, legal or NDIS advice. The Reasonable Rent Contribution rules and rates are set by the NDIS, depend on current pension and rent assistance rates, and can change over time. Always check the current figures on the NDIS website and confirm the exact amount for a home in its residency or SDA service agreement before you move in.
