San Francisco’s housing stock is essentially a physical timeline. Victorians and Queen Annes (1850s-1906) appear in Alamo Square, the Haight, Duboce Triangle, and parts of the Mission: ornate, narrow, and tall with bay windows and decorative trim. Edwardians (1906-1920s) came after the earthquake and are wider, simpler, and sturdier. Marina-style homes (1920s-1940s) feature attached garages, center patios, and stucco facades. Rousseau/Storybook homes (1930s-1940s) cluster in the Sunset and Richmond with arched doors and French Revival detailing. Mid-century homes (1940s-1960s) appear on the hillside neighborhoods with open layouts and picture windows.
