[Update: 2/3/17] A previous version of this story incorrectly reported that the fire was set intentionally.

An overnight 2-alarm structure fire in Alamo Square forced five people to vacate two three-story Victorian houses at 1214 and 1216 Fulton St.

According to SFFD, four adults and an infant were displaced as a result of the blaze, which was reported around 3:30am. On Twitter, neighbor Haresh Kumar said firefighters took about 90 minutes to contain the fire.

No injuries were reported.

Located inside the city's Alamo Square Landmark District, both homes damaged in this morning's fire were constructed in 1883, according to city records. The building at 1216 Fulton St. was the scene of a fire in 2015 that torched a shed attached to the rear of the building.
