One person was injured after a fire caused extensive damage to a house and also damaged adjacent homes in Round Lake Beach Tuesday afternoon, fire officials said.

The Greater Round Lake Fire Protection District responded around 1:44 p.m. Tuesday to the 2500 block of North Mallard Lane in Round Lake Beach for a report of a structure fire.

Greater Round Lake Fire Protection District Battalion Chief Jay Vande Berg said firefighters arrived on the scene within 5 minutes of the call.

They found heavy fire conditions from the rear of a two-story, single-family home.

The alarm was upgraded to a box alarm through the Mutual Aid Box Alarm System (MABAS) for additional assistance.

Multiple hose lines were deployed to extinguish a large amount of fire on multiple floors and in the attic, Vande Berg said.

The fire was contained to the house of origin but adjacent homes sustained heat damage due to the size and intensity of the fire.

Vande Berg said all occupants of the home had escaped the residence before the fire department’s arrival.

One occupant was evaluated on the scene by paramedics for smoke inhalation.

The fire was declared under control around 2:34 p.m., Vande Berg said.

Crews worked an additional 90 minutes to salvage property and extinguish hot spots.

The residence was extensively damaged and uninhabitable, displacing a family, Vande Berg said.

The cause of the fire remains under investigation.

The Greater Round Lake Fire Protection District was assisted by the Antioch, Countryside, Fox Lake, Grayslake, Gurnee, Lake Zurich, Lake Villa, McHenry and Spring Grove fire departments.
