Home modifications
NDIS home modifications are changes to the structure, layout or fittings of a participant's home that help them use it safely because of their disability, such as grab rails or step-free showers. They are funded from the Capital – Home Modifications budget and are either minor (Category A or B) or complex.
Also called: NDIS home mods, Home modification funding, Minor home modifications, Complex home modifications, Disability home modifications
Key takeaways
- Home modifications are funded in the Capital – Home Modifications budget and can only be used for the modifications described in the plan.
- Minor home modifications are non-structural and low risk; complex ones are structural or custom-built and usually need building approvals.
- Any occupational therapist can assess Category A minor modifications; Category B and complex modifications need a specialist home modification assessor.
- Minor modifications don't need builder's quotes because the NDIA uses a set budget; complex modifications need itemised quotes.
- If you rent, the NDIA needs the owner's written permission for the specific modifications before it can consider funding them.
- The NDIS generally doesn't fund cosmetic finishes, pools or spas, extensions, or renovations unrelated to disability.
What are NDIS home modifications?
NDIS home modifications are changes to the structure, layout or fittings of a participant's home that help them access and use it safely because of their disability. They range from grab rails and lever taps to step-free showers, ramps and lifts. If they meet the NDIS funding criteria, they are funded in the Capital – Home Modifications budget of the plan.
The NDIA describes home modifications as custom-built changes to your home to help you access and use areas of it (NDIS Our Guidelines). They are often considered where a change helps someone shower, use the toilet, get in and out of the home, move between rooms, prepare meals or reduce the risk of falls.
Home modifications sit in capital supports, alongside assistive technology. The funding can only be used for the modifications described in the plan, which makes them a stated support in practice: you can't move the money to other supports.
How NDIS home modifications work: minor vs complex
The NDIA sorts home modifications by risk and cost. The category decides who can assess the need, whether quotes are required and how the funding is set.
Minor home modifications
Minor home modifications are straightforward, non-structural changes that don't alter the supporting structure of the house, are relatively low risk and usually affect only one or two areas of the home. There are two categories, A and B, split by cost (Category B also covers minor changes to a bathroom floor). The current cost thresholds are on the NDIA's minor home modifications page.
- Category A: any occupational therapist can do the assessment, including your usual OT. Examples include grab rails, lever-style tapware, low-cost ramps and widening internal non-structural doorways.
- Category B: needs a home modification assessor, an OT with specialist home modification skills.
- No builder's quote is needed for minor home modifications. The NDIA uses a set budget for each type of modification, based on current market costs and adjusted for location using the Modified Monash Model.
Complex home modifications
Complex home modifications are custom-built or structural changes, often across several areas of the home, that are higher risk or higher cost. They usually need building approvals or permits and certification of the finished work (complex home modifications page). Examples include bathroom floor changes such as step-free showers, permanent ramps, major plumbing or electrical work, and lifts.
- A home modification assessor assesses the need and designs the scope, often with a building construction practitioner who advises on design and cost.
- The NDIA asks for itemised builder's quotes based on the same scope of work, so they can be compared. The guidelines describe a maximum of two quotes for the delegate's decision.
- For high-risk or high-cost work, the NDIA can fund an independent building works project manager who checks the work meets legal requirements and the building contract. They must be independent of the builders who quoted.
| Feature | Minor – Category A | Minor – Category B | Complex |
|---|---|---|---|
| Type of change | Simple, non-structural, low risk | Non-structural, higher cost, or minor bathroom floor changes | Structural or custom-built, often several areas |
| Who assesses | Any occupational therapist | Home modification assessor | Home modification assessor |
| Builder's quotes | Not needed | Not needed | Itemised quotes on the same scope |
| Building approvals | Rarely | Sometimes | Usually, plus certification |
| Examples | Grab rails, lever taps, low-cost ramps | Larger non-structural works, minor bathroom floor changes | Step-free showers, permanent ramps, lifts |
What the NDIS will and won't fund
Like every NDIS support, a modification must be reasonable and necessary: related to your disability, effective, good value, and not more appropriately funded by another system. The guidelines list things the NDIS generally won't fund.
| Usually funded (if criteria are met) | Generally not funded |
|---|---|
| Grab rails, handrails and lever taps | Cosmetic finishes, such as your choice of tiles or tapware |
| Ramps and step-free entries | Standard furniture, fixtures and fittings |
| Accessible bathrooms and step-free showers | Swimming pools, spas, saunas, steam rooms and hydrotherapy pools |
| Wider doorways and changes to room layout for access | Extensions that make the house bigger, such as adding a storey |
| Kitchen changes so you can prepare meals | Renovations, restorations or repairs not related to your disability |
| Lifts and platform lifts (usually complex modifications) | The general costs of moving house |

How to get home modifications in your NDIS plan
- 1Raise the needTell your planner, local area coordinator or support coordinator what you can't do safely at home.
- 2Get owner consent if you don't own the homeAsk the owner, landlord or body corporate for written permission for the specific changes, and whether they'll need removing later.
- 3Get an assessmentAn occupational therapist assesses Category A needs; a home modification assessor handles Category B and complex modifications.
- 4Get quotes if the work is complexFor complex modifications, get itemised builder's quotes on the same scope of work. Minor modifications don't need quotes.
- 5Submit the requestSend the assessment, consent and any quotes to the NDIA, for example as part of a plan reassessment.
- 6Engage the builder and check the workOnce funded, sign a contract for the approved scope. For high-risk work, use the independent building works project manager.
Tips for a strong request
Home modification requests are decided on evidence. These habits make the decision easier and faster:
- Describe the task, not just the product. "I can't step over the bath edge to shower without help" explains the need better than "I need a new bathroom".
- Show what else was tried. If assistive technology such as a shower chair or transfer bench isn't enough, the assessment should say why.
- Link it to your goals. Explain how the change supports your independence, safety or the people who help you, including informal carers.
- Think about the future. If your needs are likely to change, ask the assessor to design for that, and say whether you plan to stay in the home.
- Keep every document together: the assessment, owner consent, quotes and any building approvals, so nothing holds up the decision.
If you rent or don't own the home
Before the NDIS can consider funding, it needs written permission from the legal owner of the property, or their representative, authorising the specific modifications recommended. If you rent, the NDIA also needs to know whether your landlord will require the modifications to be removed at the end of the lease. Talk to your landlord early, before detailed plans or quotes are commissioned (How can you get home modifications in your plan?).
Social housing providers have their own obligations to make reasonable adjustments for tenants with disability. The NDIA may fund some or all of the modifications for social housing tenants in certain circumstances, so check with your housing provider first.
Home modifications vs SDA and assistive technology
Home modifications change the home you already live in. Specialist Disability Accommodation (SDA) funds a purpose-built dwelling for people with extreme functional impairment or very high support needs. You don't need SDA funding to get a home modification, and most people with home modification funding don't live in SDA.
| Support | What it funds | Key difference |
|---|---|---|
| Home modifications | Changes to the home you live in | Fixed to the building; capital budget |
| Assistive technology | Equipment you use, such as a shower chair or hoist | Usually portable and moves with you |
| Specialist Disability Accommodation | A purpose-built dwelling for people with extreme functional impairment or very high support needs | The NDIS funds the housing itself, with strict eligibility |
| Supported Independent Living | Support workers in the home | Funds people, not building works |

- OTs assess and recommend modifications
- The test every modification must pass
- The other capital support category; often considered first
- Purpose-built housing, a separate support
- Adjusts minor modification budgets for location
What providers need to know
Builders, designers and assessors working on NDIS home modifications should read the NDIA's guide to providing home modifications. Key points:
- Who can quote depends on how the plan is managed. If the home modification funding is NDIA-managed, quotes need to come from registered NDIS providers. If it is plan-managed or self-managed, quotes can come from unregistered builders.
- Quotes must be itemised and detailed enough to compare against the same scope of work, or to audit later.
- Work to the approved scope. Variations need to go back through the participant and, where needed, the NDIA.
- Use a written service agreement or building contract that sets out the scope, timeframes, payment stages and warranties.
If a participant disagrees with a home modification decision, they can ask for an internal review and then apply to the Administrative Review Tribunal (What if you don't agree with our decision?).
Common mistakes
- Getting builder's quotes for a minor modification. They aren't needed; the NDIA uses a set budget.
- Starting work before the funding is in the plan, then trying to claim it afterwards.
- Leaving landlord or body corporate consent until after the assessment.
- Asking for upgrades that aren't disability-related, such as premium finishes or a bigger kitchen.
- Spending capital funding on other supports. It can only be used for the modification described.
- Using a project manager who also quoted for the job. They must be independent.
Example
Illustrative example (fictional). Mei, 58, has multiple sclerosis and lives in a house she owns. Getting over the bath edge to shower has become unsafe, and the two steps at her front door are hard to manage.
Her usual occupational therapist assesses her and recommends grab rails, a handheld shower and a small ramp at the front door. These are Category A minor home modifications, so no builder's quotes are needed, and the NDIA funds them in Mei's Capital – Home Modifications budget using its set budgets.
A year later, Mei needs a step-free shower. Because this changes the bathroom floor and plumbing, it is assessed by a specialist home modification assessor. Mei gets two itemised quotes on the same scope of work and the NDIA funds the modification, including an independent building works project manager because the work is structural.
Frequently asked questions
What home modifications does the NDIS fund?
The NDIS can fund disability-related changes to your home that meet the reasonable and necessary criteria, such as grab rails, ramps, accessible bathrooms, wider doorways, kitchen changes and, where nothing else works, lifts. It generally doesn't fund cosmetic finishes, pools, extensions or unrelated renovations.
What is the difference between minor and complex home modifications?
Minor home modifications are straightforward, non-structural, low-risk changes affecting one or two areas of the home. Complex home modifications are structural or custom-built, often across several areas, are higher risk or cost, and usually need building approvals and certification.
Do I need quotes for NDIS home modifications?
Not for minor home modifications: the NDIA uses a set budget for each type of modification. Complex home modifications need itemised builder's quotes based on the same scope of work, and the guidelines describe a maximum of two quotes for the decision.
Can the NDIS fund home modifications in a rental property?
Yes, if the modifications meet the funding criteria and the owner gives written permission for the specific changes. The NDIA also needs to know whether your landlord will require the modifications to be removed when your lease ends.
Who can assess home modifications for the NDIS?
Any occupational therapist, including your usual OT, can assess Category A minor home modifications. Category B minor modifications and complex home modifications need a home modification assessor, who is an OT with specialist home modification skills.
Does the NDIS pay for bathroom modifications?
It can, if the change is disability-related and meets the funding criteria. Simple changes like grab rails are usually minor modifications. Changing the bathroom floor, such as building a step-free shower, is a Category B minor or a complex modification, depending on the work.
What budget do NDIS home modifications come from?
Home modifications are funded in the Capital – Home Modifications budget of your plan. That funding can only be used for the home modification supports described in the plan, not for other supports.
Related terms
- Assistive technology (AT)Assistive technology (AT) is equipment, technology or devices that help an NDIS participant do things they otherwise couldn't, or do them more easily or safely. The NDIA groups AT into low, mid and high cost, and the cost and risk of an item decide what evidence is needed before it is funded.
- Capital supportsCapital supports are one of the four NDIS support budgets. They fund higher-cost assistive technology, equipment, home and vehicle modifications, and specialist disability accommodation. The funding is stated, so it can only be used for the items the plan describes, often after the NDIA has seen quotes or assessments.
- Modified Monash Model (MMM)The Modified Monash Model (MMM) is the Australian Government's seven-level classification of how remote a location is, from MM 1 (major cities) to MM 7 (very remote). The NDIS uses it to decide whether national, remote or very remote price limits apply to a support and how much provider travel time can be claimed.
- Occupational therapy (OT)Occupational therapy (OT) in the NDIS is therapy from an AHPRA-registered occupational therapist that helps a participant build or maintain skills for everyday activities, such as self-care, household tasks, work and community access. It is usually funded from the capacity building budget.
- Quotable supportsQuotable supports are NDIS support items with no set price limit. The provider gives the NDIA a quote, and the support is funded as a specific stated item in the participant's plan. Examples include a live-in carer, host family arrangements and specialised transport. They can only be claimed when stated in the plan.
- Reasonable and necessaryReasonable and necessary is the legal test in section 34 of the NDIS Act that the NDIA uses to decide which supports to fund in a participant's plan. A support must meet every criterion, including helping with goals, value for money, being effective and beneficial, and being most appropriately funded by the NDIS.
- Specialist Disability Accommodation (SDA)Specialist Disability Accommodation (SDA) is NDIS funding for housing built to a specialist design standard for people with extreme functional impairment or very high support needs. SDA pays for the dwelling, not the support inside it: residents pay rent and living costs, and support is funded separately.
- Stated supportsStated supports are supports in an NDIS plan whose funding can only be spent on the specific support described, not moved to other supports. Examples include assistive technology, home modifications and SDA. In new framework plans, NDIS rules declare which supports are stated.
