About Tenderloin Neighborhood Development Corporation
Since 1981, TNDC’s mission has been to provide safe, affordable housing with support services to low-income people in the Tenderloin community and to be a leader in making the neighborhood a better place to live. With 31 buildings in several San Francisco neighborhoods, TNDC provides homes and support services to over 3,200 low-income seniors, families, people with disabilities, emancipated youth and formerly homeless individuals. Support services include 19 on-site social workers, the free TNDC Tenderloin After-School Program, and a Community Organizing program to encourage residents to get involved in making positive change in their neighborhoods.

The Tenderloin neighborhood is located in the northeast section of San Francisco, near to the city’s center. Bordered on the south by Market Street, a main thoroughfare of San Francisco, the Tenderloin Neighborhood is one of the city’s oldest and most diverse neighborhoods, containing many historical buildings.
Today, 31,176 people live within the roughly 50 square blocks that comprise the Tenderloin. The neighborhood still has a high level of poverty, particularly concentrated in the central core just north of Market Street, with higher incomes on the western and northern perimeters. Households are predominantly small, and a high percentage of people live with disabilities.
Currently, there is no full service grocery store serving the Tenderloin neighborhood. The Architecture at Zero 2013 competition project would provide the only full service grocery store to serve the community.
Current Site Conditions
The competition site is at the northwest corner of the intersection of Taylor and Eddy Streets in San Francisco. The site is 22,341 square feet and is currently used as a surface parking lot. The site is in the Tenderloin neighborhood of the city and is zoned for Residential-Commercial Combined, High Density.
Typical conditions surrounding the site include high density residential development, including a significant number of residential hotels, with ground floor commercial/retail uses. Surrounding buildings range in age and height, and include some low/mid-rise buildings interspersed with high rise residential towers and hotels. The site is located a half block to the east of a neighborhood-serving open space park, Boeddeker Park.
San Francisco’s climate is characteristic of the cool-summer Mediterranean climate of California’s coast, generally characterized by mild, moist winters, and dry summers. Since it is surrounded on three sides by water, San Francisco’s weather is strongly influenced by the cool currents of the Pacific Ocean, which produce a remarkably mild year-round climate with little seasonal temperature variation.
During the summer, rising hot air in California’s interior valleys creates a low pressure area that draws winds from the North Pacific High through the Golden Gate, which creates the city’s characteristic cool winds and fog. The fog is less pronounced in eastern neighborhoods and during the late summer and early fall, which is the warmest time of the year.
The dry period of May to October is mild to warm, with average high temperatures of 65–71 °F (19–22 °C) and lows of 51–56 °F (11–13 °C). The rainy period of November to April is slightly cooler, with high temperatures of 58–65 °F (15–18 °C) and lows of 46–51 °F (8–10 °C).
