Fire Insurance Maps
Fire Insurance Maps at the Newberry
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, their construction materials (masonry, frame, etc.), and use (garage, bakery, residence, etc.), and other information. These maps were created to help insurers determine the level of risk involved in insuring properties against fire. Fire insurance maps were published by several companies, but the largest producer was the Sanborn Map Company. As a result, fire insurance maps are often referred to as “Sanborn maps,” regardless of the map publisher’s name.
The Newberry has fire insurance maps for many Illinois towns, including Chicago. Some are available only in hard copy; others are available online. None of these atlases are duplicated exactly at other libraries, because each atlas includes dated revisions unique to each hard copy.
