What are the local zoning regulations for 221 San Carlos St ?

RTO-M (RESIDENTIAL TRANSIT ORIENTED- MISSION)

RTO-M (RESIDENTIAL TRANSIT ORIENTED- MISSION) Districts are intended to recognize, protect, conserve, and enhance areas characterized by a mixture of houses and apartment buildings, covering a range of densities and building forms. 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. Limited small-scale neighborhood-oriented retail and services is common and permitted throughout the neighborhood on Corner Lots only to provide goods and services to residents within walking distance, but the districts are otherwise residential.

The primary purpose of these districts is to preserve and enhance areas with a mix of houses and apartments, offering various densities and building forms. These multi-family moderate-density regions are strategically located within a short walk of transit and neighborhood commercial areas. 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.

Permitted Non-Residential uses: Limited corner commercial uses, agriculture, neighborhood, passive outdoor recreation, child care facility, public facilities, residential care facility, and mobile food facility.

What neighborhood is 221 San Carlos St located in?

Inner Mission, San Francisco

The Inner Mission, District 9c, is a Mission District microhood bounded on two sides by highway 101, Dolores Street (where it borders the Mission Dolores and Noe Valley neighborhoods), and Cesar Chavez Street, where it borders Bernal Heights.

Located near the center of the City, the Inner Mission is bikeable, walkable, and has great public transportation, including two BART stations, freeway access, and bus lines.

One reason the Inner Mission is cool is because it’s hot — compared to the rest of foggy San Francisco, that is. People also love the area because it’s at the apex of all that is happening in the tech economy and culturally, including a vibrant café culture, great nightlife, an eclectic mix of new developments and classic, older San Francisco architecture.
