Room-by-room accessibility planning

Bathroom. This is where the money and the risk both concentrate. The three things that matter are getting in (a curbless or low-threshold shower rather than a tub wall), staying upright (grab bars with real blocking, a seat, a handheld sprayer), and sitting down and getting up (toilet height and a clear approach). ADA reference points: grab bars 33–36 inches high resisting 250 pounds of force (§604.5), a shower seat 17–19 inches above the floor (§608.4), a handheld spray unit with a hose at least 59 inches long (§607.6), and shower thresholds no more than ½ inch (§607.2). A full bathroom remodel runs $6,456–$24,715 nationally with an average of $15,586, per This Old House's 2026 data.

Entry. One step-free way in, ideally the one everyone uses. If a ramp is needed, the ADA slope limit is 1:12 — one foot of ramp per inch of rise — with a 30-inch maximum rise per run, level landings top and bottom, and handrails on both sides when the rise exceeds 6 inches (§405). A nine-inch step therefore needs a nine-foot ramp before landings. That geometry surprises people, and it's why regrading a walkway or building a gentle earth berm is often better-looking and cheaper than a wooden ramp bolted to the porch.

Bedroom, hallways and laundry. The single highest-value structural change in many two-story houses is moving the bedroom downstairs, which needs a full bathroom on the same level to be worth anything. Hallways want 36 inches of clear width, more where a 180-degree turn is involved — the ADA calls for 48 inches at the turn with 42 inches on approach, or 60 inches at the turn with 36 on approach (§403.5). Laundry moved out of the basement is a quiet, underrated win: it removes a stair trip carrying an unbalanced load, which is exactly the situation falls happen in.

Kitchen. Real accessibility work here is expensive and rarely urgent, so do the cheap parts first: pull-out shelving in base cabinets so nothing lives at floor level, a lever or touch faucet, task lighting over the counter and the range, and contrast between countertop and floor. The bigger moves — a 34-inch counter section with knee clearance underneath, a wall oven at reach height, a cooktop with front controls — belong in a kitchen remodel you were already going to do, not in a standalone accessibility project.

How to choose

Do the bathroom first, always

Wet surfaces, hard fixtures, tight space, and a task nobody skips. If the budget only covers one room, it covers this one.

One step-free entry beats three modified ones

Pick the entrance with the shortest, flattest approach and the best drainage. Make that one genuinely level and well-lit. Leave the others alone.

Check the turn, not just the width

A 36-inch hall is fine to travel and hard to turn a walker in. Where the route turns 180 degrees the ADA wants 48–60 inches depending on approach width. Measure the corners in your house.

Downstairs bedroom only counts with a downstairs bathroom

A first-floor bedroom that still requires stairs at 2 a.m. has solved nothing. Budget the two together or don't start.

Keep kitchen work cheap unless you're already remodeling

Pull-outs, lighting, a lever faucet and contrast get you most of the benefit. Lowered counters and knee clearance are a remodel-scale change and rarely the reason someone can't stay home.

Move the laundry up out of the basement

Carrying a basket down stairs is one of the highest-risk routine tasks in a house. Relocating the machines is often cheaper than any other structural change on this list.
