Our History

TNDC formed in response to growing threats of gentrification as three luxury hotels eyed the neighborhood. Alongside neighborhood activists, we formed one of the country's first Community Benefits Agreement and began TNDC's legacy of preserving existing affordable housing and transforming  buildings into homes.

To address the aspirations and need of residents, TNDC employed three strategies in service of these goals. The first was property acquisition, to ensure long-term affordability by removing units from the speculative real estate market. The second was tenant organizing, with the aim of creating cooperatively owned and self-managed communities.The third was activism, on the part of the organization and through mobilization of local residents, to protect those residents’ interests in the face of proposed neighborhood development.

Between 1981 and 1988, TNDC acquired eight buildings (around 500 homes). With a grant from Franciscan Charities, TNDC purchased its first building—the Aarti Hotel—developing 40 units of permanently affordable Single Room Occupancy housing and kick-starting the process of cooperative development. Shortly after, TNDC purchased three additional properties—Civic Center Residence, Sierra Madre Apartments, and Yosemite Apartments—comprising nearly 300 additional affordable homes. In its first decade of operations, TNDC focused on renovating these and four other deteriorating structures and ensuring that tenants stood on a solid foundation of affordable rents, greatly improved living conditions, and protection from unwarranted evictions.

At a neighborhood level, TNDC joined forces with other activists in the face of a proposed development of three luxury hotels and helped develop one of the nation’s first community benefits agreements, the hotels contributing millions to fund affordable housing and job creation for Tenderloin residents. The coalition’s work also led to a downzoning of the neighborhood that limited building heights and prohibited most commercial uses above the second floor. TNDC had thus established itself as a strong advocate for local residents in issues that affect their lives.

A Franciscan friar since 1982, Brother Kelly Cullen served as TNDC’s Executive Director for 12 years and led the Tenderloin Youth Advocates. Called a “practical visionary” and “activist rock star,” Brother Kelly had a talent for connecting people’s passion for human rights with concrete action—a guiding force of TNDC’s work to this day.

A tireless and fierce advocate for the Tenderloin community, Kelly transformed TNDC from a grassroots operation into the leading community development organization it is today.

TNDC has been profoundly shaped by Kelly,” said Don Falk, former TNDC Chief Executive Director. “His values and priorities suffuse the organization. He believed in focusing on ‘the poorest of the poor,’ he wanted to ‘own land’ as an anti-gentrification strategy, he was driven in helping TNDC grow so it could do more… all of these things have become part and parcel of what TNDC is and how we operate.”

When Kelly became Executive Director in 1993, TNDC had 8 buildings with around 475 units. By his departure in 2005, he had helped TNDC more than double its portfolio to 20 buildings with 1,800 homes, making TNDC the most notable community-based developers in the country.

Kelly had deep compassion and respect for people,” said Paul Sussman, TNDC’s former Chief Financial Officer, who served on TNDC’s Board of Directors with Kelly and worked closely with him after joining the staff as CFO. “He always lived in the neighborhood and moved day and night in the Tenderloin. He believed things could change for the better, that people could change for the better. He believed that you could have a dream, go for it, that you could bring people along and achieve it.”

In Kelly's honor, we have named one of our buildings after him, Kelly Cullen Community, and recognize an outstanding community leader each year at the TNDC Anniversary Celebration with the Brother Kelly Cullen Service Award. 

Between 1993 and 2005, under the leadership of then Chief Executive Director Kelly Cullen, TNDC embarked on a period of expansion by building new units and tripling its housing portfolio from 489 to almost 1,800 homes. It was recognized as one of the most notable community-based developers in the country. Between 2005 and 2016, in addition to pursuing planned developments, TNDC experienced two unanticipated growth events. In 2009 we absorbed the San Francisco affordable housing portfolio of Citizens Housing Corporation, comprising 540 homes (30 percent of TNDC’s portfolio at that time). Then in 2015–16 we acquired and renovated over 700 homes from the San Francisco Housing Authority, as part of the SFHA’s decision to transfer ownership and management of its properties to nonprofit housing developers.

TNDC has continued to develop housing of increasing complexity and size. More units have been designed specifically for seniors, families, and people experiencing homelessness. In addition, TNDC sought out projects in partnership with other community-based organizations, and undertook its first joint venture with a market-rate developer in 2011. See how many buildings we operate and people we serve today.

A pioneer in permanent supportive housing, TNDC has long understood that providing affordable housing for people with low incomes also means attending to the support service needs of those tenants to ensure they remain stably housed. In 1996, under the auspices of what is now the Tenant and Community Services department, TNDC employed its first social work staff to provide housing-based, opt-in support services to tenants throughout its portfolio. 

TNDC has long taken a comprehensive approach to community development. In the Tenderloin, TNDC’s commitment to preserving the neighborhood also includes securing and sustaining critical elements of a healthy community, including increasing opportunities for youth, improving access to nutritious and affordable foods, and promoting thriving, culturally relevant retail.

Given the few outdoor spaces to play and inadequate number of youth programs in the neighborhood, TNDC’s Tenderloin After-School Program (TASP) was established in 1993 to provide children and youth with a safe and enriching environment staffed by caring adults, supporting their development with out-of-school-time programming after classes and during school vacations.

Recognizing the limited availability of fresh produce, affordable food options, and cooking facilities in the Tenderloin, TNDC has sought to improve the supply of, and demand for, healthy food. It also operates community food distribution sites outside of its properties.

To deepen its commitment to activism and resident leadership, TNDC hired its first full-time Community Organizer in 2007. Initially, the focus was on mobilizing TNDC tenants around affordable housing and Tenderloin neighborhood issues and on voter education and advocacy. In time, TNDC offered leadership training and stipends to residents who wanted to become more civically engaged in matters like safety, transit justice, and food security.
