Some homes are more accessible than others. And the types of accessibility that are needed can vary. Sometimes of the things that can make a home more accessible for someone with a disability or handicap, can also make it more convenient and safer for everyone else too. For instance, an easier to open door knob can help those with arthritis or paralysis, but can also be easier for a child or someone with full hands to open.
