Group R classification refers to which type of occupancy?

Group R classification specifically pertains to residential occupancies, which includes buildings that are used as a place for people to live. This classification encompasses a variety of housing types, including single-family homes, multifamily dwellings, apartments, and shelters. The primary focus is on providing housing for individuals or families, which is why "residential" is the most accurate choice.

In the context of the other options, residential care refers to facilities that provide care for individuals who may need assistance with daily activities, such as group homes or nursing facilities, which are classified differently. Research facilities focus on laboratories or environments for scientific inquiry and experimentation, whereas recreational spaces include areas designed for leisure activities, such as parks or sports complexes. Each of these classifications serves distinct purposes and aligns with specific codes and standards that differ from those applicable to residential buildings.
