What are the local zoning regulations for 21 Columbia Square St ?

NCT-SOMA (SOMA NEIGHBORHOOD COMMERCIAL TRANSIT)

The SoMa Neighborhood Commercial Transit District (SoMa NCT) is located along the 6th Street and Folsom Street corridors in the South of Market. The commercial area provides a limited selection of convenience goods for the residents of the South of Market. Eating and drinking establishments contribute to the street’s mixed-use character and activity in the evening hours. A number of upper-story professional and business offices are located in the district, some in converted residential units.

Active, neighborhood-serving commercial development is required at the ground story, curb cuts are prohibited and ground floor transparency and fenestration adds to the activation of the ground story. While offices and general retail sales uses may locate on the second story or above of new buildings, most commercial uses are prohibited above the second story. In order to protect the balance and variety of retail use, bars and liquor stores are allowed with a conditional use. Continuous retail frontage is promoted by prohibiting drive-up facilities, some automobile uses, and new non-retail commercial uses. Above-ground parking is required to be setback or below ground. Active, pedestrian-oriented ground floor uses are required. Housing development in new buildings is encouraged above the ground story. Housing density is not controlled by the size of the lot or by density controls, but by bedroom counts. Given the area’s central location and accessibility to the City’s transit network, parking for residential and commercial uses is not required.

The primary purpose of the SoMa Neighborhood Commercial Transit District, situated along the 6th Street and Folsom Street corridors in the South of Market, is to offer a range of convenience goods for local residents. The district's vibrant character is enhanced by various eating and drinking establishments, contributing to a lively atmosphere during the evening. Additionally, the area accommodates upper-story professional and business offices, with some located in repurposed residential units, further enriching the district's diverse landscape.

What neighborhood is 21 Columbia Square St located in?

South of Market, San Francisco

“SoMa” refers most specifically to the section closest to the Mission, with the most restaurants and nightlife; “Yerba Buena” is in the middle, and is known for its density of museums and shopping; and "South Beach" is on the side next to the Bay (although there’s no beach to speak of) and is full of high-rises and not too much else. South Beach is quickly becoming its own neighborhood, but for now it falls under the general SoMa umbrella.

This area was once zoned primarily for commercial use and that history is still present in the lofts and apartments fashioned from converted warehouses and office space. On smaller side streets you’ll occasionally find a Victorian or a modern condominium. Brick walk-ups are common, as are high-rises; these tend to be more common the further west you go.
