Practical home changes for staying safely at home

Entries, stairs, and doors

From the car to the kitchen: thresholds, levers, and the path

The fall often happens between the car door and the kitchen chair. Sills, mats, steps, and a place to put the groceries are the work.

Families renovate the bathroom and leave the route from the driveway alone. That route is where people carry bags, look for keys, step over a hose, and catch a toe on a welcome mat. The CDC's stair and floor rules apply to every foot of it: objects off the walking surface, rugs secured or gone, rails where there are steps, light at the top and bottom. The National Institute on Aging adds a bench by the door, pruned shrubs, and a walk free of hoses and uneven joints. This page walks that path in order, from the car door to a place to sit down.

The car door needs a level place to open

A person who uses a walker or a wheelchair needs the car door to open fully onto a surface that is flat, not onto the lawn and not into a slope that rolls the door shut. A driveway that is cracked, heaved, or sloped sideways makes the first step the hardest one. You may not rebuild the driveway this year. You can still park in the same spot every time, on the soundest part of the concrete, and keep that strip clear of bins, oil stains that are slick, and the other car.

If you are repaving, ask for a level access aisle beside the parking spot, wide enough for the door and the device. The ADA parking figures for public lots, including an access aisle, are a useful picture even though a house driveway is not a public lot. A garage is often better than the driveway because the floor is flatter and the weather is out. The garage only works if the path from the car to the kitchen door is clear, lit, and free of the stored treadmill. Paint or tape a keep-clear zone. People fill garages because the floor looks like storage. It is a hallway.

The garage-to-house door is often the real front door. Give it the clear width and the low threshold you would want at the street. A step down from the kitchen into the garage is a classic trip because the eyes are on the car. Mark the edge, light it, and plan to remove it if anyone in the house is becoming unsteady.

Every sill is a small step

Small changes in floor level A quarter-inch vertical edge is the usual maximum. Above that, the edge has to be beveled or ramped. Lower floor Higher floor Up to 1/4 inch may be vertical (ADA 303.2). From 1/4 to 1/2 inch, bevel at 1:2 or gentler (ADA 303.3). Taller than 1/2 inch is a ramp problem, not a threshold.
Small changes in floor level. A quarter-inch vertical edge is the usual maximum. Above that, the edge has to be beveled or ramped.

Section 303 of the 2010 ADA Standards is the home version of common sense, written down. Up to one-quarter inch, a vertical edge is allowed. From one-quarter to one-half inch, bevel it no steeper than 1:2. Door thresholds, section 404.2.5, top out at one-half inch, with a limited exception of three-quarters of an inch for existing thresholds that are beveled. Take a ruler to the front sill, the slider, the garage step, and the marble saddle at the bathroom. Anything taller than half an inch is not a threshold problem. It is a step or a ramp problem.

Welcome mats are the extra threshold people add on purpose. A thick coir mat with a curled corner is a toe catch. The CDC says remove rugs or secure them so they cannot slide. At a door, a thin mat in a recessed frame is the version that does not add height. If you cannot recess it, skip it, and use a scraper outside the walking line. Doormats that live on top of a sill stack two level changes.

Sliding patio tracks fill with dirt and become a ridge. Clean the track, and if the slider is the daily door, budget a low-profile sill the way you would at the front. A wooden plate someone screwed on top of the track to "make it easier" often makes a new lip. Remove experiments that did not lower the number on the ruler.

Handles, keys, and the second hand

A lever handle works with a closed fist or an elbow. A knob does not. The same is true of a deadbolt thumb-turn that is small and stiff. Have a locksmith or a carpenter replace knobs on the route with levers, and ease the deadbolt so it turns without a two-handed fight. The force benchmark in ADA section 309.4 is 5 pounds, one hand, no tight twist. A house is not cited for that. A stiff lock still causes people to pull on the door while their feet are on the mat.

Where to put keys is a tradeoff, not a product recommendation. A keypad avoids a key the person drops, and it creates a code to manage when the person moves or a helper changes. Hide-a-key rocks are widely known to burglars. The NIA checklist, written with safety in a broad sense, talks about secure locks and, in the Alzheimer's materials, about spare keys in a thoughtful way because locking yourself out is its own emergency. Do not hang a key on the doorframe. Do decide, with the household, who can get in if the resident falls and cannot reach the lock. A lockbox with a code held by a neighbor is a common arrangement. It is not a medical-alert contract. The alert guide covers monitored lockboxes, which are a different system with a fee and a company.

A peephole at one standing height fails a seated person and a shorter person. Two peepholes, or a sidelight with a shade the resident controls, let someone see who is there without opening the door. Security and access are both served by being able to see.

The walk itself

Cracks, heaved slabs, and a slope that throws a walker toward the flower bed are the middle of the route. The NIA checklist asks you to deal with uneven surfaces, hoses, and anything else that trips. Coil the hose on a reel off the walk. Move the downspout extension out of the path. If a tree root has lifted a square, that square is a ramp you did not design. Grinding a small lip, or replacing a square, is maintenance. A long cross-slope toward the street may be how the driveway was poured. If a wheelchair drifts toward the drive every time, the fix is a flatter route, often the other side of the house, not a lecture about steering.

Rails belong on any run of steps, both sides when you can, at a graspable height. The stair guide has the inches. One step is still a step. A single step off a patio with no rail and no contrast is a frequent fall because it does not look like a staircase, so nobody installs a rail. Add the rail. Mark the nosing.

Light the whole walk, not a floodlight aimed at eye level. The CDC wants a light and a switch at the top and bottom of stairs. On a walk, that means you can see the next joint before you step on it, from the car and from the door. Shield the bulb. A sensor that turns off after thirty seconds will turn off while someone is still unloading the trunk. Set a longer timeout or use a switch.

A place to arrive

The path should end at a chair, not at a project. The first room needs a seat with arms where bags can be put down and a coat taken off without balancing on one foot. The chair guide covers seat height. The NIA bench at the door is the outdoor version. Use both if the distance from the door to the kitchen chair is a hike across a rug and a cord.

If the path crosses a room that has become storage, the path loses. The CDC says to ask someone to move the furniture so the path is straight. Do that before you buy a new walker. A walker needs a straight line more than it needs a stylish room.

Walk it with the bag you usually carry

  • Park in the usual spot. Open the door fully. Is the ground flat and clear?
  • Walk to the door the person uses. List every lip over one-quarter inch, every mat, every hose, every heaved joint.
  • Stand at the door with the bag in one hand. Is there a bench, a lever, and a light?
  • Go in. Can you reach a chair with arms without stepping over a rug or a cord?
  • Do the walk after dark. Add light where you hesitated.
  • Fix the smallest lips and the mats this week. Price a true zero-step or a ramp only for the rise that is left.

The point of the walk-through is a short list, not a mood. The house-walk guide is the same method for every room. Start here because this is the route that decides whether the person still goes out.
