Getting Home Modifications Approved

How to get NDIS home modifications approved: building a strong case, the evidence that helps, common reasons for delays or knockbacks, and how to respond.

Getting home modifications approved comes down to evidence. When the NDIA can clearly see that a change is related to your disability, reasonable and necessary, and the most effective option, decisions are smoother. This guide explains how to build a strong case with your occupational therapist and builder, what evidence helps, and the common reasons requests get delayed or knocked back.

Frequently asked questions

What's the single most important thing for approval?

A strong OT assessment that clearly links each change to your disability and your goals. It's the foundation of the request, and it's what most other evidence supports. See How home modification assessments work.

Why was my request delayed?

Delays usually come from missing pieces — an incomplete quote, an unclear disability link, thin functional evidence, or missing owner consent if you rent. Ask what's needed, gather it with your OT, and the request can move forward.

Do I need two quotes?

For complex, structural work, often yes — two quotes help show the cost is reasonable. Minor work usually needs only one. Your OT and builder can advise what's expected for your modification.

What if my modification is knocked back?

A knockback often means evidence is missing, not that the change is refused forever. Ask for the reasons, address the gaps with your OT, and ask for the decision to be looked at again if needed.

Can my plan be changed if my needs increase?

Yes. Your plan can be reassessed — the current term for what used to be called a review. Talk to your planner or LAC if your circumstances or needs have changed since your last plan.

How do my OT and builder work together?

The OT identifies what you need; the builder confirms what's possible and what it costs. When they collaborate, the recommendation and quotes fit both your needs and the building, which makes approval smoother.
