Which term is a building or portion thereof containing three or more dwelling units with independent cooking and bathroom facilities?

• A. Building
• B. Anchor Building
• C. Apartment Building
• D. Flexible Plan and Open Plan Educational or Day-Care Building

Answer: (C)

In NFPA 101, the key idea is how building types are defined by resident units and private facilities. An apartment building is the term used for a building or portion that contains three or more dwelling units, with independent cooking facilities (kitchens) and bathrooms in each unit. That combination—three or more dwelling units plus private kitchens and bathrooms—is what sets this category apart from other building types.

So this term best fits the description because it explicitly matches the requirement of multiple dwelling units with self-contained cooking and bathroom facilities. The other options don’t describe a residential multi-unit with private facilities: a generic building is too broad, an anchor building refers to a different concept, and a flexible/open-plan educational or day-care building describes non-residential occupancies.
