Vol. I, No. 39 · San Francisco — Friday, September 18, 2026 · Price: eighty-two names, one filing

BY MAXINE DOLAN, CITY DESK

Kelly Cullen Community, at 220 Golden Gate Avenue, was San Francisco’s Central YMCA for a century before the Tenderloin Neighborhood Development Corporation converted its 174 rooms into permanent housing in 2012. Today 172 of those rooms are reserved, by the city’s own accounting, for people who moved in straight from the street.

That single building sits inside a citywide pattern the city does not publish as a single figure. San Francisco’s affordable-housing agency tracks 5,628 units across the city as “homeless-designated,” reserved specifically for tenants who were homeless when they moved in. The Tenderloin holds 1,769 of them, 31 percent of the total, the largest share held by any of the city’s 38 mapped neighborhoods. The neighborhood holds only 17.5 percent of the city’s affordable housing overall. Most San Franciscans live outside the Tenderloin. For them, the housing the city built for its most vulnerable residents sits in a neighborhood they rarely have reason to walk through.

Add South of Market, the runner-up, and the concentration sharpens. The two neighborhoods together hold 30.8 percent of the city’s affordable stock but 54.5 percent of its homeless-designated units, in a live query of the city’s own portfolio file run tonight. Thirty-six other neighborhoods, from Bayview to the Sunset, share the remaining 45.5 percent.

The Tenderloin’s share traces to its own building stock. More than half of the portfolio’s single-room-occupancy units citywide, 2,416 of 4,746, sit in the neighborhood, almost all of them former hotels the city bought and converted rather than built new. The file’s own construction dates show six of the neighborhood’s largest fully homeless-designated buildings completed as conversions between 1997 and 2012: the Arlington, the Ambassador, Hotel Essex, Arnett Watson Apartments, the Senator, and Kelly Cullen Community.

South of Market took a different path to a similar number. Its largest homeless-designated building, at 1064 Mission Street, holds 256 units, more than any single property in the portfolio. Every one of them opened new in December 2022 rather than being carved out of an old hotel. The Tenderloin reached its total by retrofitting what it already had. South of Market reached a comparable total by building new.

Neither pattern is new. City agencies have leaned on single-room-occupancy conversions in the Tenderloin for decades. The rooms are already subdivided, which makes them cheaper to retrofit into supportive housing. South of Market had more vacant industrial land instead, which made new construction the more available path there. The concentration numbers themselves come from a live query of the city’s own accounting, run tonight, with no modeling involved: high confidence. This desk cannot prove a single deliberate policy caused the overlap. Land and buildings were available in these two neighborhoods when the money arrived, and that is the simpler explanation. This desk states it with moderate confidence.
