What is the minimum square footage required for a single resident room?

The correct answer indicates that the minimum square footage required for a single resident room is 100 square feet. This requirement is established within regulations aimed at ensuring adequate space for residents in facilities such as nursing homes or group homes, contributing to a safe and comfortable living environment. A room of at least 100 square feet provides enough space for essential furniture, personal belongings, and movement, which is critical for both the physical and psychological well-being of the residents.

Larger room sizes, such as those listed in other options, go beyond the minimum requirement and may be beneficial for comfort but are not necessary to meet the standard. Thus, while those higher numbers might represent larger spaces, they do not reflect the regulatory baseline that ensures basic livability standards are met. This distinction highlights why 100 square feet is the established minimum as it effectively balances regulatory standards with practical living conditions.
