How does the S500 define complex residential buildings?

The S500 defines complex residential buildings as facilities that encompass multiple living units such as townhouses, apartments, and hotels. This definition highlights the multifaceted nature of these structures, where various residents occupy separate units within a single building or complex. These types of buildings often have unique drying and restoration needs due to their size and the number of residents, which can complicate the drying process following water damage.

In contrast, the other options focus on specific types of residential buildings that are either limited to single-family homes, cater exclusively to certain demographics like seniors or students, or are not representative of the complex nature that includes multiple living units in a single structure. By defining complex residential buildings in this way, the S500 provides a clear framework that professionals can rely on when addressing the challenges associated with drying and restoration in such environments.
