NDIS Home Modifications: The Step-by-Step Process
In this article
What home modifications qualify for NDIS funding?
NDIS home modifications are changes to your home that improve access, safety, and independence — such as ramps, widened doorways, accessible bathrooms, ceiling hoists, or structural changes for wheelchair access. They're funded under your Capital Supports budget when they're directly related to your disability and are considered reasonable and necessary. Home modifications are one of the 15 NDIS support categories.
The key test: the modification must help you do something you can't currently do (or can't do safely) because of your disability. It must also represent value for money — the NDIA won't fund a full bathroom renovation if a simple grab rail would achieve the same outcome.
Common funded modifications
- Ramps and step-free entrances
- Widening doorways and hallways for wheelchair access
- Accessible bathrooms — level-access showers, grab rails, hand-held shower heads
- Ceiling hoists and tracking systems
- Modified kitchens — lowered benches, accessible storage
- Structural changes for wheelchair circulation space
- Accessible entry systems — automated doors, intercoms
- Specialised flooring to reduce trip hazards
🏠 Important: The NDIS funds the modifications themselves — not the underlying property. You (or the property owner) are responsible for ongoing maintenance, insurance, and any eventual restoration. If you rent, you'll need the landlord's written consent.
The NDIS Home Modifications Step-by-Step Process
1. Identify the need
This usually starts with you, your family, or a support worker noticing a safety or access issue at home. Maybe you can't get into the bathroom safely, or stairs are becoming impossible to navigate.
2. Get an OT home assessment
An occupational therapist (OT) with home modification experience visits your home and conducts a comprehensive assessment. They evaluate how you move through your home, identify barriers, and determine what modifications would address them. This is a detailed report — it's the foundation of your entire application.
3. OT prepares a scope of works
The OT develops a detailed scope of works document. This isn't just "install a ramp" — it specifies materials, dimensions, placement, building code compliance, and exactly what needs to happen. The more detailed this is, the smoother the next steps will be.
4. Obtain building quotes
The OT or a building designer sends the scope of works to licensed builders or modification specialists to obtain quotes. You typically need at least two competitive quotes for NDIA approval. For complex modifications, you may also need architectural drawings or engineering reports.
5. Submit to the NDIA
Your OT, support coordinator, or plan manager submits the entire package — assessment report, scope of works, quotes, drawings, landlord consent (if renting), and any supporting evidence — to the NDIA for approval. This is the part where most delays happen, so a complete application is critical.
6. NDIA review and approval
The NDIA reviews your submission. For minor modifications this can take a few weeks. For complex modifications ($20,000+), expect months. The NDIA may ask follow-up questions or request additional information. If approved, you receive formal confirmation and funding is allocated.
7. Construction
Once approved, the builder proceeds with the work. Your plan manager pays the builder directly from your Capital budget, usually in stages (deposit, progress payment, final payment on completion).
8. Final inspection
Your OT should inspect the completed work to confirm it matches the scope of works and meets your needs before the final payment is released.
Complex vs. minor modifications
The NDIS splits home modifications into two categories:
- Minor modifications (typically under $20,000) — Simple changes like grab rails, handheld shower heads, or small ramps. These need a basic OT assessment and a single quote. Process is relatively fast.
- Complex modifications (typically over $20,000) — Larger projects like bathroom renovations, kitchen modifications, or structural changes. These need a comprehensive OT report, detailed scope of works, building drawings, multiple quotes, and potentially building permits. Expect a longer timeline.
Common delays and how to avoid them
- Incomplete OT reports — Make sure your OT has experience with NDIS home modification applications. A vague report will be sent back for more detail.
- Missing landlord consent — If you're renting, get written consent early. Without it, the NDIA won't proceed.
- Insufficient quotes — The NDIA needs evidence of value for money. One quote isn't usually enough for anything beyond minor modifications.
- Unrealistic budgets — If quotes come in far above what the NDIS typically funds for that type of modification, expect pushback.
- Plan expiry — Home modifications can easily take longer than a 12-month plan. If your plan is ending soon, ask your plan manager about a plan extension.
Home modifications can be life-changing — but the process is long. The single most important thing you can do is start early, work with an experienced OT, and keep your plan manager in the loop. They can't write the OT report, but they can guide you through the funding side and help keep things moving. If you're also exploring equipment, see our NDIS assistive technology guide.
