A woman and her dog were able to safely evacuate after a fire spread throughout a home in McHenry and left the structure uninhabitable Saturday evening, fire officials said.

The McHenry Township Fire Protection District responded around 11:47 p.m. Saturday to the 6000 block of Chickaloon Drive in McHenry for a report of a structure fire.

Firefighters arrived in six minutes to find a single-family residence.

McHenry Township Fire Protection District Battalion Chief David Harwood said there was heavy smoke coming from the attic space and extending throughout the building.

The sole occupant of the home and her dog had evacuated prior to the fire department’s arrival.

The house is located in an area that does not have fire hydrants, Harwood said.

The incident was upgraded through the Mutual Aid Box Alarm System (MABAS) to bring in additional water and manpower.
