A fire broke out on the 8th floor of a residential building in the 200 block of Woodside Avenue in San Francisco this afternoon, injuring one person as firefighters raced to get water on the flames. San Francisco Fire officials confirmed crews were on scene battling a 1-alarm structure fire, with the blaze contained to a single room high above the West of Twin Peaks neighborhood.
The fire was reported in the 200 block of Woodside Avenue, according to a post from SFMTA, which relayed the San Francisco Fire Department's initial dispatch. Firefighters got water on the fire and reported one injury, though further details about that person's condition were not immediately available. The address corresponds to 255 Woodside, a 109-unit affordable housing complex built specifically for low-income seniors and people with disabilities, according to BRIDGE Housing, which manages the property.

A Building With a History of Serving Vulnerable Tenants
255 Woodside was once run as public housing by the San Francisco Housing Authority before it was renovated and handed over to non-profit management in 2015 and 2016 under HUD's Rental Assistance Demonstration program, a shift meant to preserve permanent affordability for its residents, per the Mission Economic Development Agency. The building's population makes any fire response there especially fraught: San Francisco's Department of Disability and Aging Services provides city grant funding to BRIDGE Housing for dedicated on-site supportive services aimed at helping elderly and disabled tenants navigate emergencies, according to the San Francisco Human Services Agency.
Officials asked people to avoid the stretch of Woodside Avenue between Ulloa Street and Balceta Avenue while emergency vehicles worked the scene, per the same SFMTA post. That closure cuts through a stretch of road that carries Muni's 36-Teresita, 44-O'Shaughnessy, and 52-Excelsior bus lines toward the nearby Forest Hill Metro Station, according to SF.gov.
Standard Dispatch Brought Heavy Resources Fast
A 1-alarm call for a multi-story residential fire triggers a substantial response under San Francisco Fire Department protocols: three engine companies, two ladder trucks, two battalion chiefs, a heavy rescue unit, an assistant chief, and a paramedic ambulance are all typically dispatched. That scale of response reflects the department's broader capacity — SFFD operates 44 fire stations across 10 battalion districts on an annual budget of roughly $526.5 million for the current fiscal year, as Hoodline has previously reported.
Department response guidelines call for crews to arrive within minutes of dispatch to launch aggressive interior attacks and isolate residential fires to the room or unit where they started, which helps explain how firefighters were able to knock down the 8th-floor blaze before it spread further through the building. Multi-story residential buildings in San Francisco are also subject to state and municipal fire codes requiring active alarm systems, fire doors, and clear egress paths, according to SF.gov — standards designed specifically to protect occupants in high-density buildings like 255 Woodside during exactly this kind of incident.
What Remains Unclear
It is not yet known what caused the fire, the extent of the injury reported by firefighters, or whether any residents were displaced from their units. Separately, local emergency dispatch logs show a fire alarm response was also recorded on the same block of Woodside Avenue on July 30, according to Civic Informer, though it is unclear whether that earlier call is connected in any way to today's fire. Further down the same corridor sits the San Francisco Juvenile Justice Center at 375 Woodside Avenue, home to county juvenile courts, Juvenile Hall, and the SFUSD Woodside Learning Center, according to the Superior Court of California, County of San Francisco — a reminder of how much civic infrastructure lines this stretch of the West of Twin Peaks neighborhood.
