San Francisco's
Marina District is built on the site of the 1915 Panama Pacific International Exposition, which was held mostly to celebrate the city's post-earthquake resurrection. Almost none of the expo buildings were kept, and the site was redeveloped as a new, 'modern' residential district. It is almost certainly the first sizable chunk of San Francisco to have been plotted and built with the automobile in mind. In any case, Wikipedia states it was fully built out in the 1920s, which would put the majority of the district's structures within the 1918-1933 'interwar' period. Anecdotally, my great-great-grandfather lived with one of his daughters and her husband in a Marina District home that the couple had purchased brand new.
