Before anyone quotes you for anything, someone should look at the house

Decide who is doing the assessing, and what they sell

Three groups do this work: independent home-modification consultants, contractors holding an aging-in-place credential such as CAPS, and occupational therapists. An OT assessment is the clinical gold standard for how a person functions; a contractor assessment is better on what the building can be made to do. Many households benefit from both.

Watch for: A "free assessment" offered by a company whose product is a bathroom, a tub or a lift. It may be a perfectly good visit, but it is a sales call, and the conclusion is already known before they arrive.

The person who lives there is present, and does the moving

A real assessment watches the actual routine: getting out of bed, into the bathroom at night, up the steps at the front door, to the mailbox, in and out of the shower. Where the difficulty is often turns out not to be where the family assumed it was.

Watch for: An assessment done from photographs, or done with only the adult children present. The house has to be walked by the person who lives in it, at the times of day that are hard.

The route, not the room

Falls and stuck moments tend to happen along paths rather than in places: bed to bathroom in the dark, car to kitchen carrying something, back door to garden. A good assessor traces routes end to end and notices the small level change, the loose rug edge, the door that has to be pulled while holding a handrail.

Watch for: A report that lists rooms in order and never mentions getting from one to another. Doorways, thresholds and transitions are where most of this work actually lives.

Separating the urgent from the eventual

Almost every house produces a long list. The value of the assessment is the ordering: what has to change before someone comes home this week, what should happen this year, and what only makes sense to do when the bathroom is being redone anyway.

Watch for: A single undifferentiated list of thirty items. That is a survey, not advice — and it tends to become a whole-house quote, which is how modest needs turn into enormous projects.

Naming what the building can and cannot give

Some things a house simply will not do without disproportionate work: a bathroom too small for a carer to stand in, an entry that cannot be regraded, an upper floor with no route to it. An honest assessment says so early, because it changes the plan — sometimes to a different room, sometimes to single-floor living.

Watch for: Feasibility judgements made without anyone looking under the floor, at the framing, or at the drainage outside. Those answers change the price of a project by a wide margin.

Getting a written deliverable you own

You should leave with a document: findings, prioritised recommendations, rough scope for each, and any referrals. It is what lets you get three comparable quotes on the same scope, and it is what you hand to a funding programme if you apply to one.

Watch for: A verbal summary and a quote for the assessor's own work. If the only artefact is their proposal, you did not buy an assessment.

Routing the questions that are not building questions

Whether a modification is medically appropriate is an occupational therapist's or clinician's call. Whether a programme will pay for it is the programme's call, in writing. A good assessor names both routes plainly rather than answering for them.

Watch for: Anyone who tells you a benefit will cover this. Coverage under Medicare, Medicare Advantage, state Medicaid waiver programmes and VA benefits varies by programme and by plan and changes over time — only the payer can confirm it, and only in writing.
