A raging fire in Port Chester Sunday left more than a dozen people homeless Sunday.

Fire officials say flames broke around 12:30 p.m. at a three-story apartment building on North Main Street.

The fire was so intense that it eventually went to five alarms, prompting the response of approximately 200 firefighters from seven municipalities, including nearby Greenwich, Connecticut.

There are reports that the fire began on a wooden deck in the rear of an apartment building and spread to other decks then to the building.

Crews worked for hours battling the flames that destroyed the 15 units.

Luckily, everyone who was home at the time got out of the building safely. News 12 is told that about 27 people lived there.

At least two firefighters were reportedly taken to the hospital for heat exhaustion. One suddenly collapsed and was quickly attended to on the scene.

One woman told News 12 that she lost everything in her apartment, including her pet, and will have to find somewhere else to live.

The Red Cross is helping the 23 people who lived there – 20 adults and three children - and the investigation into the exact cause of the fire continues.

The building was so badly damaged it had to be taken down.

Excavators were still at the building Monday, which is still blocked off, as they continued clearing what was left.

A GoFundMe page has just been set up with an $8,000 goal. The money will go directly to families in the building who have lost everything.
