The historic Central YMCA, built in San Francisco, is a valued community
resource. Its century of service to the YMCA’s values of body, mind and
spirit made it uniquely suited for conversion into supportive housing
for the homeless and a health center serving residents and neighbors in
the Tenderloin. This integration of home and health is an innovative
approach to permanent housing for people who have been chronically
homeless or at risk of homelessness. The $55 million renovation of the
building creates a housing community of 174 micro-units of approximately
200 square feet each while preserving the sky lit second floor lobby,
full size gym, auditorium, offices and meeting rooms of the original
use. The new LEED CI Gold primary care and behavioral and mental health
clinic occupies 11,700 square feet of former locker room and support
space on the ground floor, while the original basement swimming pool has
been converted to a multipurpose room.
Renovations in the 1950’s removed the original grand stair that provided
entry direct from street to 2nd floor lobby. The building always had
separate circulation for club members, hotel guests, and visitors, but
with the removal of the stair and other circulation changes the building
became a 3D maze. The lobby was restored as the heart of the building,
with a new grand stair with a small street level lobby, and an
accessible elevator. The restored lobby improved circulation throughout
the building on the upper floors. Residential wings and 24 new units
constructed above the historic gym wrap the light well above the lobby.
Historic preservation tax credits provided partial funding for the
project and required a high degree of preservation sensitivity. The
project will also house a vulnerable population and must manage
operating costs for its non-profit sponsor. The small units preserve the
original window bays and gain spaciousness from their generous
proportions and high ceilings, while providing occupants with ample
storage, cooking facilities, and individual bathrooms. Shotcrete seismic
strengthening limits impinging on existing openings. Window repairs
preserve existing fabric while providing for energy efficiency and
comfort. The new radiant heating system, energy efficient lighting and
ventilation, and focus on healthy materials support resident well-being
and sustainability. Terrazzo stairs, tile walls, wood ceilings, and
translucent planters around the new grand stair are chosen for their
compatibility with the historic wood, tile, and marble finishes that
were meticulously restored.
Few uses could have made as fruitful a conversion of the historic
combination of recreation, office, performance, social and residential
spaces as this project. A development in which only 50% of the square
footage was proposed for residential use would have been hard to justify
in a new building. Existing public spaces in the historic building
allowed for creative programming to enhance residential use and
supplement that with health care and retail, embodying a holistic
approach to development.
