Which wall is shared by two buildings within the same building?

• A. Veneer Wall
• B. Party Wall
• C. Fire Wall
• D. Division Wall

Answer: (B)

A party wall is the wall that sits between two separate buildings and is shared by both sides. It’s built to separate the structures while being jointly owned and maintained by the adjoining property owners, and it typically carries loads from both buildings while also serving as a fire and sound barrier between them. The other terms describe walls that aren’t shared between buildings: a veneer wall is just an exterior finish applied to a structural wall, a fire wall is a specially rated barrier designed to stop fire from spreading and is usually treated as separate walls for each building, and a division wall is an interior partition that separates spaces within a single building.
