кондо

Ответ от Cheery[гуру]
A condominium, or condo, is the form of housing tenure and other real property where a specified part of a piece of real estate (usually of an apartment house) is individually owned while use of and access to common facilities in the piece such as hallways, heating system, elevators, exterior areas is executed under legal rights associated with the individual ownership and controlled by the association of owners that jointly represent ownership of the whole piece. Colloquially, the term is often used to refer to the unit itself in place of the word "apartment". A condominium may be simply defined as an "apartment" that the resident "owns" as opposed to rents.
А еще есть кооп:
A housing cooperative is a legal entity—usually a corporation—that owns real estate, consisting of one or more residential buildings. (This is one type of housing tenure.) Each shareholder in the legal entity is granted the right to occupy one housing unit, sometimes subject to an occupancy agreement, which is similar to a lease. The occupancy agreement specifies the co-op's rules. Cooperative is also used to describe a non-share capital co-op model in which fee-paying members obtain the right to occupy a bedroom and share the communal resources of a house that is owned by a cooperative organization. Such is the case with student cooperatives in some college neighborhoods in the United States.
ps: надеюсь, что перевод не нужен?
если непонятно, то кондоминимум - это аналог российского ТСЖ (товарищество собственников жилья) . То есть владельцы квартир объединяются в товарищество для совместной эксплуатации всего дома.
кооп же - когда домом владеет какая то организация, она же заботится о доме и жильцы живут по ее правилам.
