How to Write an NDIS Home Modification Report
A home modification report makes the case that changes to a participant’s home are reasonable and necessary to let them live safely and more independently. These reports carry real evidence weight, especially for complex, structural work.
This guide covers the difference between minor and complex modifications, what the OT assessment needs to capture, and how to justify the work so it holds up.

What a home modification report is for
The report has to connect the participant’s functional limitations to the specific changes in the home, and show that the modification is the most reasonable way to remove the barrier. The assessor is looking for a clear line from disability, to barrier in the home, to the recommended change.
Know minor vs complex modifications
The evidence and process differ depending on the scale of the work. Minor changes are lower risk and non-structural. Complex changes are structural and need more rigour, often including a building professional.
- Minor: non-structural changes such as grab rails, a handheld shower, or a ramp within limits
- Complex: structural work such as bathroom reconfiguration, widening doorways, or level access changes
- Complex modifications generally need drawings, building input, and more detailed justification
What the OT assessment captures
A home modification assessment is done in the actual home, because the barriers only show up in the real environment. Capture the specifics:
- Access to and around the home, and to key rooms
- Bathroom and toilet use, transfers, and falls risk
- The participant’s current method, the risk, and the effort involved
- Measurements and photographs that support the recommendation
Evidence, drawings and quotes
Back the recommendation with what the reader needs to approve it: measurements, photographs, and for complex work, plans or drawings and builder quotes. Show that options were considered and that the recommended modification is value for money.
Reasonable and necessary, and why the write-up takes time
Tie each modification to the functional need and the risk of not doing it, and confirm it is not more appropriately funded elsewhere. Our Section 34 guide covers this reasoning in depth.
The assessment is the quick part. Pulling the measurements, risks, and justifications into a full report is where the hours go. Carearoo drafts the home modification report in your structure from your notes, so you review and sign off rather than starting from a blank page.
Frequently asked questions
Who writes NDIS home modification reports?
An occupational therapist assesses and writes the report. Complex, structural modifications usually also involve a building professional.
What is the difference between minor and complex home modifications?
Minor modifications are non-structural and lower risk, such as grab rails or a handheld shower. Complex modifications are structural, such as bathroom reconfiguration, and need drawings, building input and more detailed justification.
What evidence does a home modification report need?
The functional assessment in the home, measurements and photographs, consideration of options, and for complex work, plans and builder quotes.
