RTO and RTO-M Districts are composed of multi-family moderate-density areas, primarily areas formerly designated RM and RH-3, and are well served within short walking distance, generally less than one-quarter mile, of transit and neighborhood commercial areas. Transit available on nearby streets is frequent and/or provides multiple lines serving different parts of the City or region.

Small-scale, neighborhood-oriented retail and services are limited to Corner Lots to serve residents within walking distance. The focus remains residential, allowing only retail compatible with housing, with restricted hours of operation and no off-street parking for these local businesses.

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

What neighborhood is 90 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.
