Single room occupancy (more commonly SRO, sometimes called a single resident occupancy) is a term used primarily in Canadian and American cities referring to a multiple-tenant building that houses one or two people in individual rooms (sometimes two rooms, or two rooms with a bathroom or half bathroom), or the single room dwelling itself. SRO tenants typically share bathrooms and/or kitchens, while some SRO rooms may include kitchenettes, bathrooms, or half-baths. Although many are former hotels, SROs are primarily rented as a permanent residence.
