Residential care settings are an important option for older adults and people with disabilities who require long-term services and supports (LTSS). Residential care settings are licensed and regulated at the state level, and all states have at least one category of residential care. The purpose of this Compendium is to summarize and compare states’ residential care setting regulations. Although states generally have provisions covering the same areas—such as staff training—their requirements vary considerably. This Compendium notes similarities and differences among states and provides examples from state regulations.
