High-rise housing governed by the concept of co-ownership has had a long history in Chile. However, although the concept implies the value of community life, it is suggested that there would be a disconnection between the project, co-ownership and ways of living, bringing about diverse and complex neighborhood relationships according to the type of proposal. In order to analyze how the relationship between the public policy approach and the spatial results of the high-rise residential project has been established, the article develops a historical journey, exposing the multiple typological and spatial transformations that it has undergone and its relationship with the notion of co-ownership. Currently known as social condominiums, it is concluded that their production has been defined by a predominantly economic approach, such as efficiency in the use of the land or the number of housing units, which has determined the progressive rationalization of the projects, which, with time, has obscured the notion of co-ownership.
