The city firefighters stayed on scene until 5 a.m. to ventilate the building, said the Norwalk Fire Department.
Firefighters were on scene till 5:00 am, ventilating the building.
The incident followed a busy Wednesday, July 17, when Norwalk firefighters responded to several calls related to the strong electrical storms that swept through the area during the afternoon and into the evening.
A shed in the backyard of a home on Ledgewood Drive caught fire as a result of a possible lightning strike around 8:45 p.m., according to the fire department.
Other possible strikes resulted in several alarms, trees on wires or wires arcing, and a tree burning from the inside-out in the woods off North Bridge Street, the fire department said.
Causes of the shed and building fires are being investigated.
