Residential Board and Care Occupancies include 4 or more people unrelated to the owners, with lodging, boarding, and personal care.

• A. Dormitory
• B. Residential Board and Care Occupancies
• C. Mixed Use Occupancies
• D. Mercantile Occupancies

Answer: (B)

The main idea here is how occupancy classifications are determined by who lives in the building and what services are provided. If four or more people who are unrelated to the owner live there and the facility offers lodging, meals (boarding), and personal care, it falls under Residential Board and Care Occupancies. This category is used because the residents aren’t related to the owner and they receive ongoing personal care, which changes the life-safety requirements compared to simpler lodging or dormitory settings.

Why this fits better than the other options: a dormitory is typically lodging without the level of personal care or supervision found in board-and-care settings. Mixed-use occupancies mix different use types in one building, and mercantile occupancies are retail spaces, neither of which match a residence that provides personal care to unrelated residents.
