The facility must provide individual mailboxes for residents as part of which area?

The requirement for individual mailboxes for residents falls under the category of Administration and Public Areas. This is because such a feature is often associated with the operational and communal aspects of the facility. Providing mailboxes enhances the residents' sense of privacy and ownership, allowing them to receive personal correspondence securely. This arrangement is typically managed within the administrative capabilities of the facility to ensure that mail is distributed effectively and that the common areas are designed to cater to the needs of all residents.

Additionally, while mailboxes might be located close to residents' rooms or in common recreational areas for convenience, the responsibility for managing mail services and ensuring adequate provisions is part of the administrative oversight of the facility.
