What is the difference between Co-operative society and Condominium?

In USA, and possibly in other locales, condominium is unique to a form of real estate ownership. A condominium community is governed by a set of governing documents that usually defines a board of directors who operate the corporation, and more.

In a cooperative society, there is no implied definition of real estate ownership, and the over-arching foundation is that everybody agrees about everything.

A condominium can be regarded as a private democracy, where owners vote on some items, and board votes generally define action that is taken by the corporation.
