Apartment Building, Residential Rochester, MN – Early morning apartment fire suppressed by sprinkler system June 3, 2016 viking210 Around 7 a.m. Wednesday morning the Rochester Fire Department responded to a fire alarm at the Boulder Apartments in southeast Rochester. When crews arrived they found water running from under the doorway and could smell smoke. No one answered the door so firefighters broke through the locked door and discovered a small fire in the corner of the living room that had started moving up the wall and ceiling. The sprinkler system had activated, suppressing the fire. Firefighters were able to shut off the sprinkler system however there is extensive water damage to the third floor apartments as well as the apartments directly below on the 1st and 2nd floors. Damage is estimated at $20,000. The City of Rochester’s Fire Marshal’s Office is investigating the fire, so far it appears to be unintentional. No one was in the apartment at the time of the fire but fire crews did rescue a young cat which they turned over to Animal Control until the occupant could be located and notified.
