Officers arrived to the scene at approximately 7 p.m. and heavy smoke had already filled the building, but all occupants were reportedly evacuated.
Nassau County fire marshals, members of the Arson Bomb Squad and representatives of the Hempstead Building Department were also on site.
Two people were evaluated by the Nassau County Police Medic and reportedly refused further treatment.
Three firemen were treated at the building for smoke inhalation. One fireman was treated for a minor cut on his hand.
The police are still investigating, but so far there is nothing suspicious about the fire.
