The purpose of this study was to identify design evaluation items for assisted living facilities for the elderly. To achieve this purpose, the 23 design issues in assisted living facilities were examined through literature analysis. Then, the field studies were carried out by using these items and by asking open questions, or any other suggestions for unexpected, but important design issues in their facilities. The field studies were conducted through interviews with several residents and surveys with staff in six selected assisted living facilities in Cincinnati, Ohio. Finally, the 23 design evaluation items for assisted living facilities were identified. These items can be used as evaluation criteria or design guidelines for assisted living facilities.
