Shultz's house might be @ 999 Green between Leavenworth and Taylor
999 Green, "The Summit," Architects: Claude Oakland and Associates, 1965

This looming residential high-rise was built for Joseph Eichler, developer of much of the stucco housing in San Francisco's Sunset District in the 1940s and 1950s and the open-beamed, glass and wood alternative to ranch houses on the San Francisco Peninsula in the 1960s. Eichler was the first occupant of the two-story penthouse. Later owners of the penthouse have been Pat Montandon, a figure in San Francisco's society pages in the 1970s, and more recently George and Charlotte Maillard Shultz. An open dead space above the garage and under the tower may have been an accommodation to residents on Russian Hill Place to allow them to retain some view toward the bay.
