Damage was confined to the electrical panel and a minor smoke condition in the lower level of the structure.  16 firefighters checked for extension and secured the property until Eversource arrived.  The Monroe Fire Marshal estimates the damage to the structure at 75-hundred dollars. The property owners were allowed to remain in the structure.
