What neighborhood is 445 Webster St located in?

Hayes Valley, San Francisco

Hayes Valley is a cool, revitalized neighborhood in the Western Addition. The main commercial stretch, Hayes Street, teems with upscale boutiques for designer fashions and home decor, plus dessert shops, chill watering holes and a wide array of on-trend restaurants. The close-knit neighborhood features a community garden, a pocket park with art installations, and access to music and theater near the Civic Center.

Hayes Valley south of McAllister Street was spared the fires that followed the 1906 San Francisco earthquake. It was a multi-ethnic neighborhood, becoming, with the blossoming of the Fillmore district after World War II, an African-American neighborhood. As recently as the mid-1985, this neighborhood (and, indeed, the Western Addition in general) was considered one of the most dangerous places in the Bay Area.
