What an OT Housing Assessment Covers

Also called an occupational therapy housing assessment or an NDIS housing assessment. What we look at, which report you actually need, the tools we use, and what ends up in the document a decision-maker reads.

The point of it

Your current home is the evidence

A housing assessment answers a specific question: does the place you live meet your needs, and if not, what would? The reason it happens in your home rather than a clinic is that the failures are physical and particular. A step, a doorway width, a bathroom a wheelchair cannot turn in, a laundry down an external stair.

Those details are what turn a general claim about needing better housing into evidence a delegate can act on. An assessment conducted anywhere other than your home cannot produce them.

Which report

The family of housing-related OT reports, and which one you need

People arrive asking for a housing assessment when the thing they actually need has a different name. This is the map.

ReportAnswers the questionTypically when
Home modification assessmentCan this home be changed to work for you?The dwelling is broadly right but specific features fail
Assistive technology assessmentWould equipment resolve the difficulty?Before concluding the housing itself is the problem
SDA assessmentDo you need purpose-built specialist housing, and of which design category?Modifications and equipment would not be enough
SIL assessmentHow much daily support do you need, and in what pattern?The question is people, not the building
ILO assessmentWhat support arrangement would let you live the way you want?You want support without a staffed shared house
Functional capacity assessmentWhat can you do, and what support do you need overall?Access requests, plan reviews, external review

A good assessment often establishes that a cheaper answer works. If a rail and a level-entry shower resolve the problem, that is a better outcome than specialist housing, and we will say so. See home modifications and assistive technology for those pathways.

What we assess

The two halves of a housing assessment

You

Self-care, transfers, mobility indoors and out, meal preparation, household tasks, communication, cognition and safety. Observed across a realistic routine rather than asked about.

Overnight and after hours

What happens at night, what support is needed, and what would happen in an emergency. Daytime-only assessments routinely miss this, and it is often decisive.

The dwelling

Entry and exit, doorway and corridor widths, circulation space, bathroom and toilet layout, kitchen usability, floor surfaces, steps and thresholds, laundry and bin access. Measured, not estimated.

Equipment and fit

What assistive technology you use, whether it fits the space, what has been tried and abandoned, and what could not be installed here.

Support arrangements

Who provides support, when, and what informal help family are absorbing. Support that is invisible in the file is support that will not be funded.

Alternatives

Whether modifications, equipment or a different support model would resolve the problem. The NDIA will ask, so the report answers it directly.

How we assess

Method, and the tools behind it

Observation carries the assessment. Standardised measures anchor it to something a reader can compare against.

We assess across one or two visits, at more than one time of day where fatigue or variability is part of the picture. With your consent we also speak with family, carers, support workers and your treating team, because the people around you see the parts of the week you would not describe to a stranger.

Where they add something, we use validated tools: the WHODAS 2.0 for overall functioning, the COPM for the activities you identify as mattering, and the Lawton IADL Scale for household and community tasks. For children, age-referenced measures such as the Vineland-3 or Pedi-CAT. Tools are chosen to fit the person and the question, not applied as a set.

The measurements of the dwelling matter just as much. A report saying a doorway is too narrow invites a question. A report saying the bathroom door is 720mm against a wheelchair requiring 850mm does not.

Preparing

What to have ready, and what not to bother with

Useful to have

Your NDIS plan and number, previous OT or allied health reports, specialist letters, a list of equipment you use, and where possible somebody present who sees you day to day.

Please do not

Tidy up, move furniture, or have a good day for our benefit. The obstacles are the evidence. A home arranged for a visitor tells us nothing about the home you actually live in.

The report

What you receive

Your situation and history

Written so somebody who has never met you can follow it.

Functional findings

Area by area, with standardised measures where they add something, explained in plain terms.

What the dwelling does

Specific barriers with measurements, and the consequence of each spelled out rather than listed.

Support needs across 24 hours

Type, intensity and pattern, including the overnight picture and what informal support is currently absorbing.

Housing requirements

What a suitable home would need to provide, and where SDA is in question, the design category the evidence supports and why.

Alternatives considered

Why modifications, equipment or a different support model would or would not resolve it.

After the report is delivered we answer questions from your planner or support coordinator about it, and provide updated evidence if a review requires it. A report nobody can follow up on is worth considerably less than one somebody stands behind.

FAQs

OT housing assessments: common questions

What is an OT housing assessment?
An occupational therapy assessment of how you function at home and whether your current housing meets your needs. It produces a written report used as evidence for NDIS home and living decisions, including Specialist Disability Accommodation.
Is a housing assessment the same as an SDA assessment?
In practice the terms are used interchangeably. A housing assessment is the broader piece of work. Where the question is specifically about SDA, the same assessment also addresses eligibility and which design category the evidence supports.
How is it different from a functional capacity assessment?
An FCA describes how you manage everyday activities and what supports you need. A housing assessment does that too, and adds the dwelling: what fails, why, and what a suitable home would have to provide. If you need both, one assessment can usually address both questions.
Do you assess my current home or a proposed one?
Your current home, because that is the evidence. What does not work where you live now is what demonstrates the need. Where a specific dwelling is being considered, we can also comment on whether it would meet your requirements.
What assessment tools do you use?
It depends on the person and the question. Commonly the WHODAS 2.0, the COPM and the Lawton IADL Scale for adults, and age-appropriate measures such as the Vineland-3 or Pedi-CAT where a child is being assessed. Tools support the clinical reasoning; they do not replace observation.
How long does it take?
Usually one or two visits, with the written report delivered within 2 to 3 weeks, depending on complexity. Tell us at referral if you are working to a plan review date.
What should I have ready?
Your NDIS plan and number, any previous OT or allied health reports, specialist letters, a list of equipment you use, and if you can, someone present who sees you day to day. Nothing needs to be tidied or prepared beyond that.
Who can refer me?
You can contact us directly. Support coordinators, planners, GPs, specialists, hospital discharge teams and other allied health professionals also refer. You do not need a doctor’s referral.
Will you tell me if I do not need one?
Yes. If a home modification assessment, an equipment review or a different report is what your situation actually calls for, we will say so before anything is booked.
