The three shoreline community houses on Shore Drive in Oyster Harbor were next to one another. Matthew Tobia, the battalion chief for Anne Arundel County Fire Department, said 100 firefighters were at the scene.
Tobia said the flames melted the siding off three houses across the street, but firefighters were able to save those homes. Several hoses also burned. Fire crews were still dousing hot spots as of 2:30 a.m., dealing with icy streets and strong winds.
Two firefighters were treated for minor injuries from the blaze, which started around 10:30 p.m. No one else was hurt.
A family of four has been displaced, and a man living in the second destroyed home is also displaced. No one was present in the third home.
Officials don't yet know how the fire started and don't plan to begin investigating until daylight.
They estimate about $2 million in damage.
