A fire in University Heights Sunday morning left a multifamily home destroyed and several buildings along Grand Avenue.

FDNY officials said the call came in just before 8 a.m. for a fire on the top floor of a building at 2321 Grand Ave.

Firefighters said cold temperatures created icy conditions and a vehicle parked in front of a fire pump delayed efforts to extinguish the blaze.

The fire was eventually brought under control, but the building sustained extensive damage, including significant water damage in the basement.

Several residents were displaced. The American Red Cross was on scene assisting those who lost their homes.

Menya Wrenn, a resident, said she was getting her children ready for school when she noticed smoke inside her apartment.

“My son was like, ‘The wall is smoking,’” Wrenn said. “So I went to see what he was talking about and the bathroom was smoking. I opened the window. The thermostat was smoking. My landlord had somebody come to fix it, but they even told my landlord it was wired wrong.”

FDNY officials said the fire was reported as an electrical fire. The cause remains under investigation.

The American Red Cross says it has registered six households including 10 adults and 12 children for emergency assistance, including financial aid and temporary lodging.

Any residents who did not connect with the Red Cross responders on scene should call 877-REDCROSS for assistance.
