AIP Resolution No. 1: I will make my home visitable.
Stairs create a grand entrance for your home, but aren't so grand for visitors or residents using wheelchairs or walkers. Consider a zero-barrier entry to your home and at least one accessible ground floor bathroom.
Not only will this make your home more visitable, it will also assist you should an older relative with mobility issues move in, or if you sustain a sports injury that precludes stair climbing during your recuperation.
On a related note, zero-threshold showers are also recommended for aging in place.
