sorry Craig dont really know here is the legal definition DWELLING HOUSE - A building inhabited by man.
A part of a house is, in one sense, a dwelling house; for example, where two or more persons rent off the owner different parts of a house, so as to have among them the whole house, and the owner does not reserve or occupy any part, the separate portion of each will, in cases of burglary, be considered the dwelling house of each.

so I would assume it means possibly

rented property ???
