Strictly defined, senior housing is a place suitable for the needs of senior citizens. Residents should be comfortable and able to traverse the place without much need for assistance. The focus for senior housing should be accessibility, modularity, and safety considerations not present in a normal setting. This might not be the best option for seniors suffering from extreme forms of Alzheimer's and dementia, both of which might necessitate memory care facilities. Otherwise, the place must simply focus on giving seniors more options in terms of quality of life. Assisted living facilities exist for this very reason. While there are independent living communities, the family of the senior citizen usually opts for a nursing home with a long term care plan for their loved one.
