If a building contains three dwelling units, what category is it?

• A. Dwelling
• B. Hotel
• C. Apartment house
• D. Lodging house

Answer: (C)

The main concept is how buildings are classified by occupancy and the number of dwelling units they contain. When a building has three dwelling units, it is considered a multi-family residential building, specifically an apartment house, because it is designed to house multiple separate households in self-contained units. Each dwelling unit is typically self-contained with its own kitchen and bathroom, allowing independent living for different families or roommates. A single family home would be a dwelling, since it serves one household. A hotel is intended for transient, short-term guests, not for multiple long-term dwelling units. A lodging house provides lodging but usually with non-self-contained rooms rented out, not necessarily multiple self-contained dwellings. So three dwelling units fit the apartment house category because the defining feature is multiple self-contained living spaces within one building.
