A resident was hospitalized and other residents, along with pets, were displaced after a fire engulfed a shed before spreading to two houses in Round Lake Beach Thursday morning.

The Greater Round Lake Fire Protection District responded around 3:24 a.m. Thursday to the 1300 block of North Williams Avenue in Round Lake Beach for a report of a structure fire.

Greater Round Lake Fire Protection District Battalion Chief Tony Carraro said police officers began evacuating the residents of two homes prior to the fire department’s arrival.

Firefighters found a fully involved shed fire and two adjacent single-family residences on fire, Carraro said.

One resident was transported by ambulance to Advocate Condell Medical Center in good condition.

The incident was upgraded to a Working Still Alarm and then the Mutual Aid Box Alarm System (MABAS) was activated to the box alarm.

Carraro said an additional upgrade to the second alarm level was made for additional fire departments to the scene.

Fire crews extinguished the fire in 45 minutes but remained on the scene locating and extinguishing hot spots for an additional hour and 30 minutes.

Carraro said the two homes sustained significant fire, smoke and water damage. They were both uninhabitable.

Firefighters were able to limit the damage to personal possessions with “careful salvage and overhaul procedures,” Carraro said.

Several pets were unharmed but also displaced along with the residents of the homes.

No firefighters were injured during the incident. Carraro said the fire’s cause and origin are under investigation.

The Grayslake, Fox Lake, Antioch, Lake Villa, Wauconda, Gurnee, Waukegan, Newport, Libertyville, Spring Grove, Nunda, Countryside, Mundelein, Lake Zurich and McHenry fire departments assisted at the scene and covered Round Lake fire stations.
