Which of the following can be considered as part of a household according to housing regulations?

In housing regulations, a PHA-approved live-in aide is recognized as a part of a household because their role is essential for the care of a household member who needs assistance due to disability or other special needs. This aide provides necessary support that can be crucial for the well-being of the individual receiving care. Importantly, the approval from the Public Housing Authority (PHA) signifies that this person’s presence is authorized and aligns with the guidelines set to facilitate the needs of the household.

Other options, while they may pertain to living situations, do not fulfill the specific criteria outlined in housing regulations for inclusion as part of a household. Immediate family members and roommates might be considered part of the household in many situations, but they do not share the same focus on caregiving responsibilities as a live-in aide does. Guests who stay for extended periods, such as those over 30 days, might populate the dwelling but don’t hold the same recognized status that comes with being an aide approved by the PHA. Thus, the inclusion of a live-in aide is explicitly codified to ensure households receive adequate support when needed, making it the correct answer.
