SAN FRANCISCO (KRON) – A “heavy fire” that broke out Tuesday near San Francisco’s famed Painted Ladies and was rapidly elevated to three alarms is now contained, according to KRON4’s Dan Kerman who is reporting at the scene.

The fire department is advising the public to avoid the area of the fire, which is on the second and third floors of a building near San Francisco’s Alamo Square. More than 100 firefighters were at the scene responding to the fire, according to a tweet from the SFFD.

The fire was at 1604 McAllister Street, which is kitty-corner to Alamo Square, adjacent to the Painted Ladies.

Two injuries were confirmed by the SFFD at a press conference. One firefighter suffered minor injuries. A resident who was evacuated with her cats was “seriously injured” and transported to the hospital, but is expected to survive.

The building houses 13 inhabitants in nine units, according to SSFD Public Information Officer Lt. Jonathan Baxter. All of them were displaced and will work with the Red Cross to get assistance, according to Supervisor Dean Preston. Local businesses Oasis Cafe and Kava Lounge have also been displaced.

Baxter confirmed that the inhabitant who was earlier reported to be in serious condition was in stable condition, along with her three cats. Baxter also said that a second firefighter had been injured and that the nature of the fire being in an older building was creating challenges for firefighters.

Both firefighters injured in responding to the blaze remained at the scene and went back to help mitigate the fire, according to a tweet from SFFD. Thirteen residents were displaced and two businesses were affected.

The department of emergency management is telling the public to “expect traffic delays, consider alternate routes, and allow for additional travel time.”

Fire investigators were on the scene looking into the cause and origins of the blaze, according to Baxter. As of yet, the fire had not extended to any surrounding structures.
