Zoning, accessory dwelling units, and family caregiving: issues, trends, and recommendations.

This article explores the relationship between zoning regulations and co-residential family caregiving in the United States. It first provides an overview of U.S. housing policies, especially zoning. We then describe major changes in family structure and composition in the United States with their implications for caregiving and discuss how multigenerational housing options, particularly accessory dwelling units (ADUs) in single-family homes, can help support family caregiving. After an overview of zoning policies and actions that inhibit ADU production, we document current trends, incorporating information from a small non-random study of ADU activity we conducted in 2004. Finally, we present recommendations for promoting more multigenerational housing as a supplement to other family support programs (e.g., dependent care assistance, family caregiver payments) and as a source of affordable, supportive housing for those families choosing co-residence as their eldercare solution.
