Shopping facilities and transit lines are conveniently located nearby, and these districts often incorporate nonresidential uses to meet the needs of residents.

Permitted Residential Uses: ADU and JADU, intermediate length occupancy use, single room occupancy, dwelling units, student housing, senior housing, group housing and homeless shelter.

Permitted Non-Residential Uses: Agriculture, passive outdoor recreation, child care facility, public facilities, and residential care facility.

40-X

No portion of a dwelling can exceed a height of 40 feet, except that the permitted height has to be reduced to 35 feet where the average ground elevation at the rear line of the lot is lower by 20 or more feet than at the front line. The height is measured by taking a point at the centerline of the building or, where the building steps in relation to a street that is the basis for height measurement.

What neighborhood is 393 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.
