What is the minimum size of a facility that must have a reception area and restroom facility designed for visitors?

The correct answer is based on the regulatory requirements outlined for Adult Residential Facilities regarding the design and structure of facilities. Specifically, a facility that serves a certain number of residents is mandated to include a reception area and restroom facilities specifically designed for visitors to ensure both accessibility and comfort.

For facilities that accommodate a specified minimum number of residents, having a reception area provides a designated space for visitors and enhances the overall experience by ensuring a professional and organized approach to visitor management. Furthermore, separate restroom facilities designed for visitors are also crucial, as they promote hygiene and cater to the needs of guests without disrupting the residents' privacy.

In this context, facilities that are designed to house 16 or more residents are required to meet these criteria. This aligns with regulations that emphasize high standards of care and service within Adult Residential Facilities.
