Quick answer: A home that has been comfortable for thirty years can become hostile in a few months. What to change, in the order that prevents the most harm.
Do the falls first
If you only do one section, do this one. Falls are the single largest acute risk and the most common route from living at home to not living at home. A hip fracture at eighty-five changes everything that follows.
Throw rugs removed or fixed down, because they are the commonest trip hazard in an older home. Lighting in every hallway, on every stair and in every bathroom, with motion-sensor night lights on the route from bed to toilet. Grab bars beside the toilet and in the shower, rated for weight and not towel rails, which come off the wall under load. A non-slip mat and a shower chair. Handrails on both sides of the stairs. Cords and clutter out of walking paths. And proper slippers with a back and a grip, not socks.
Kitchen
The stove is the item that most often prompts families to act, usually after finding a ring left on. Auto-shutoff devices exist and fit most cookers; knob covers are the cheaper version. Consider disabling the oven if it is no longer used safely.
Sharp knives into a drawer that closes. A fire extinguisher, in date, somewhere reachable. And someone other than your parent checking the fridge weekly, because expired food is both a health risk and one of the clearest early signals of decline.
Bathroom
Set the water heater to 120 degrees Fahrenheit or below. Scalding is a genuine and underrated risk when temperature perception changes, and this takes five minutes.
A contrasting toilet seat, which sounds cosmetic and is not, because a white seat on a white toilet in a white bathroom is hard to see when visual processing changes. A toilet riser if standing is hard. Lock away razors and anything harmful, and clear out old medicines.
Medication
All medicines in one place, in a weekly organiser or an automated dispenser. Old prescriptions thrown out, because a cabinet with three years of accumulated bottles is how double-dosing happens.
Switch to a pharmacy that delivers pre-sorted dose packs. It removes a weekly task that is often being done badly and nobody has noticed.
Doors and wandering, before it has ever happened
Do this before the first incident rather than after. Contact sensors or alarms on the doors that lead outside. Locks placed high or low, outside the usual line of sight. A current photograph kept somewhere findable in a panic, and a medical identification bracelet.
Move car keys, coats and handbags away from the front door. Left there, they are an instruction to leave.
Fire, and the one neighbour
Smoke and carbon monoxide detectors in every bedroom, tested monthly, with sealed long-life batteries so that testing is the only job.
A large-print emergency contact list by the phone and on the fridge. And one trusted neighbour with a key and your number. That last one is uncomfortable to arrange and is repeatedly the thing that matters most, because they are the person who notices first.
What the audit cannot fix
A safe house is not the same as a safe situation. Equipment does not supervise, and the honest test is what happens at two in the morning: if the answer is that they call for help, you are probably still fine. If the answer is that they would not realise anything was wrong, no amount of equipment closes that gap.
That is the point at which the conversation moves from safety devices to overnight or full-time care.
