People living with  dementia should have a living environment that is safe and helps them to live  as comfortably and independently as possible. As the disease progresses,  dementia impacts peoples’ ability to interact with and make sense of their  environment. Environments that are familiar, home-like, and easy to understand are  important.
Over the course of a person’s dementia, living environments need  to be modified to help the person navigate their surroundings, support their independence,  and reduce their feelings of confusion and stress. Design modifications may  include nonslip floor coverings, handrails in the shower and beside the toilet  to provide support and balance, heat and smoke sensors, and memory cues. 
When people living with dementia are no longer able to live safely and  independently in their home, they may consider moving to a more supported care  setting, such as an assisted-living facility, a dementia-friendly group home, a  retirement residence, or a long-term care home. 
Housing options for people living with dementia should ideally be financially  accessible and in close proximity to their caregivers and family. They should meet  the needs and preferences of both the person and their caregivers. Spouses wishing  to remain living with each other should have access to environments where this  is possible.
