Redmond Fire and Rescue crews responded around 7:30 Sunday night to a reported structure fire near Northwest Fourth Street and Northwest Hemlock Court. Firefighters arrived to find heavy flames coming from the front of a single-story manufactured home, with nearby homes threatened. Crews quickly stretched hose lines and kept the fire from spreading beyond the one residence. Officials say no one lives there; the home was being used for storage. Because of the volume of items inside, firefighters battled the blaze from outside for safety. Investigators say illegal fireworks ignited dry vegetation, spreading to a fence and then the home. Fireworks are banned within Redmond city limits.
