An apartment building under renovation in downtown Indianapolis caught fire Monday morning, causing an estimated $200,000 in damage. Firefighters were dispatched to the 23-unit Burton Building Apartments at 821 N. Pennsylvania St. at 6:42 a.m. No injuries were reported. A cause is being investigated. Partners in Housing typically uses the building to house U.S. military veterans who are at risk of being homeless. The building was slated to be filled with residents again in a month after renovations.
