A condominium (or condo for short) is an ownership regime in which a building (or group of buildings) is divided into multiple units that are either each separately owned, or owned in common with exclusive rights of occupation by individual owners. These individual units are surrounded by common areas that are jointly owned and managed by the owners of the units. The term can be applied to the building or complex itself, and is sometimes applied to individual units. The term "condominium" is mostly used in the US and Canada, but similar arrangements are used in many other countries under different names.
