While as a whole the Ridge Project was coed, it had separate male and female wings and a large common area in between. There would be no restrictions on when or where a member of the house could be unless such rules where passed by the members themselves. One of the first approved motions was to switch members of a floor in the women's wing with a floor from the men's. Segregation of the wings by gender was over by mid 1970s. Casa Zimbabwe's "party house" reputation originated at the Ridge Project almost right after it opened. Across the bay from San Francisco its members where at the center of then blossoming hippie movement. Similarly, the political activity present today was even more so during the same years as a large portion of the members where also participating in the Free Speech Movement that originated in Berkeley several years earlier. In 1983, several members petitioned to change house's name to "Casa Zimbabwe." Some felt that the term "project" had a negative association with public housing and that there was a frequent confusion between the names of the Ridge Project and the Ridge House next to it. The name "Casa Zimbabwe" was a reference to independence of South Rhodesia from British rule and creation of Republic of Zimbabwe. Changing the name failed several times before getting approved in 1987.
