Fire insurance maps are widely used by historians, preservationists, planners, genealogists, and others interested in seeing what particular buildings, neighborhoods, and towns looked like in the past. Fire insurance maps show the footprints of buildings and other structures, as well as the construction material (masonry, frame, etc.), use (garage, bakery, residence), and other information. As the name implies, such maps were created to help insurers determine the level of risk involved in insuring particular properties against fire. Fire insurance maps were published by several companies, but the largest producer was the Sanborn Map Company. Often, folks refer to fire insurance maps as “Sanborn maps,” regardless of the actual map producer’s name.
