One person suffered minor injuries after a fire started in an apartment Tuesday morning, leaving the building uninhabitable, Barrington fire officials said.

The Barrington Fire Department was called at 7:49 a.m. Tuesday to a report of a structure fire in the 300 block of East Russell Street in Barrington.

Barrington Fire Department Assistant Chief Bruce Peterson said the fire was called in by a resident who found smoke coming from the first floor of the 3-unit apartment building, where a sauna is located.

Responding fire crews found heavy smoke and fire on the first-floor of the building.

It was initially unclear if other residents were home, Peterson said. Fire crews searched all of the apartment units and did not find anyone inside. The fire was brought under control in 30 minutes after firefighters performed an interior fire attack.

Peterson said there was heavy fire damage to one unit and the other two units had smoke damage. Residents are being assisted by the American Red Cross after fire officials deemed the building uninhabitable.

No firefighters were injured but one resident was treated and released at the scene. Fire officials said the fire is not considered suspicious but it’s still undetermined what caused it.

The Barrington Fire Department was assisted by firefighters from Barrington-Countryside, Lake Zurich, Fox River Grove, Long Grove, Buffalo Grove and Wauconda.
