RICHMOND, Va. (WRIC) — It is believed that at least 12 apartments cannot be reoccupied after a fire at an apartment building in the Forest Hill area of Richmond’s Southside.

According to the Richmond Fire Department, crews responded to the 600 of Westover Hills Boulevard around 3:36 a.m. on Sunday, Oct. 2 for a report of a fire at an apartment building. When they got there, they saw heavy smoke coming from the second floor and declared an active fire.

Crews worked to extinguish the fire, which had spread to the roof of the apartment building, and checked each floor for occupants, all of whom had gotten out safely. A dog in a crate was found in a first floor apartment and was taken out of the building.

By about 4:30 a.m., most of the fire had been extinguished and crews were working to put out a small fire in the attic of the apartment from which the fire is believed to have originated. The fire was marked under control at 4:47 a.m. Sunday.

One firefighter reported a hand injury but no one else was hurt. It has been determined that at least 12 of the building’s apartments cannot be reoccupied and the Red Cross is expected to assist around 25 people affected by the fire.

The Richmond Fire Investigations Unit is working to determine the cause of this fire.
