Officials say the initial report was made just before 5 p.m. One fire fighter sustained minor injuries but is expected to be okay. Both Hamden and New haven responded.
The fire is believed to have broken out on the 3rd floor. Officials at the scene believed two families lived in the home. The people who lived in the home were out-of-state at the time and no injuries were reported.
Neighboring homes were not impacted. A cause has not been determined yet. Firefighters say the home will be uninhabitable for a while with heavy smoke and water damage to the second floor as well.
