"Aging in Place" is a new initiative that believes a person, as they age, should be able to remain at their house by re-modeling it for accessibility.
One of the challenges a disabled person faces is that most residential doors are less than 32" wide, especially in bathrooms where they can be 24" wide. A wheelchair cannot enter or exit a room that has a door smaller in width than 32" wide. Remodeling a home to enlarge the doorways may be just a matter of replacing the door with pocket doors, or even curtains, in order for a person in a wheelchair to avoid the maneuvering problems.
