About Us  is provided to you as a service of the University of Southern California Leonard Davis School of Gerontology. The web site was originally created by the National Resource Center on Supportive Housing and Home Modification, with support from the Archstone Foundation. We are headquartered at the University of Southern California Andrus Gerontology Center in Los Angeles, California.

What is Home Modification?  Home modification refers to converting or adapting the environment in order to make performing tasks easier, reduce accidents, and support independent living. Home modification, ranging from low-cost to more expensive adaptations, includes removing hazards (e.g., clutter, throw rugs), adding special features or assistive devices (e.g., grab bars, ramps), moving furnishings, changing where activities occur (e.g., sleeping on the first instead of second floor) and renovations (e.g., installing a roll-in shower). In some cases, modifying the home may also require repairs such as improved wiring to eliminate the need for dangerous extension cords or fixing loose stair treads.

What is the role of home modification in fall prevention?  The addition of supportive features can help reduce accidents such as falls, a leading cause of death for older Americans. Six out of 10 falls occur in homes which typically contain a high prevalence of hazards such as loose throw rugs, the lack of tub/shower grab bars, and obstructed pathways. Home modifications can reduce the demands of the environment while making the home safer and more supportive. Research indicates that the most effective interventions to prevent falls for persons at moderate to high risk of falls are multi-factorial, and include environmental modifications, medication management and physical activity.
