Which type of lodging is NOT considered a Residential Dwelling Unit?

Inpatient medical care facilities are not classified as Residential Dwelling Units because their primary function is to provide medical care and support for patients rather than serve as living accommodations for residents. These facilities are designed to cater to individuals who require ongoing medical supervision, treatment, and care, often involving specific medical equipment and resources that differ from typical residential settings.

In contrast, long-term rental apartments, single-family homes, and long-term care facilities are all considered forms of residential dwelling units, as they provide a place for individuals or families to live with the intent of long-term occupancy. Residential units typically emphasize privacy and the ability to form a household, which is not a characteristic of inpatient medical facilities, where the focus is on providing treatment rather than residential living. Understanding the definitions and purposes of these different types of lodging is crucial for plumbing professionals when analyzing building codes, plumbing installation requirements, and occupancy considerations.
