Grab rails and handrails, anchored into studs or blocked into masonry rather than just the drywall, on stairs, in hallways, and beside the toilet and tub.
Straight and curved stair lifts, threshold and modular ramps for a step at the front door, and widened doorways where a wheelchair or walker will not clear the frame.
Walk-in showers and low-threshold tub conversions, replacing a step-over edge with a level entry and a seat, done in a bathroom you can use again the same evening.
