Stairs, small bathrooms, and too-high cabinets and countertops are examples of homes built in the U.S. that you may own and could cause problems for the elderly, according to Tulsa World in "Transition your home for aging in place."
Therefore, if you are planning to stay in your own home during your elder years or if you are a younger person moving an elderly relative in with you, then you need to make sure your home is appropriate for the elderly.
You might need to make some changes to your home.
In many places, there are experts on elder living who can assist you by coming to your home and telling you what changes you should make.
Even if you do not live in an area where that service is available, a little common sense will go a long way in helping you figure out how to adapt your home for an elderly resident.
