Use handrails wherever there are steps. These should be easy to see, grip and painted a color that is contrasting to the wall behind the rail. Textured, non-skid runners can be used. The handrail should extend past the top and bottom steps for easy grasping before and after the assent or descent. If there are two floors in the house, a basket at the bottom of the stairs to put items in to be taken upstairs will save trips.
Ramps are especially helpful when there are step-downs in the home or on a porch that has steps.
If light switches are difficult to see or locate, use luminescent light switch plate or switches with night light outlet. Also, contrasting tape around the light switch will make it stand out against the wall. If possible, it might be best to convert problem doors to sliding doors or, if privacy isn't an issue, removing them altogether. If a person lives alone or needs to provide privacy for guests, curtains will make it easier to see or wheelchair users to pass through the doorways. If doors are not removed, they should always be open all the way or closed all the way.
