What are fire insurance maps and how are they important to family & local history? Named for D. A. Sanborn, a civil engineer from Sommerville, Massachusetts, these maps and others like them were designed to "detail the structural characteristics and functions of buildings and their environs as they pertain to fire hazards or prevention." [Fire Insurance Maps : their history and applications, by Diane L. Oswald]
For each community, there are typically a handful of single or multi-page maps representing the 1890 thru 1935 time period. Streets are identified by name and each structure is hand-drawn, showing such elements as dimensions, how many floors, stairways, windows, and doors.
The residential areas within the boundaries of the drawn map are similarly diagrammed, however (and this is the negative part of these maps), there are no names of owners. Some businesses are named, but usually, with some exceptions, there is only a broad category description such as those listed above.
Fire insurance maps should be a mainstay for those researching historical structures, with businesses in particular. Larger multi-building companies have some amazing detail including uses of each building, like Martin Manufacturing Company, Berrien Springs, a manufacturer of cue tips & chalk in 1932, shown here.

The Sanborn Fire Insurance Maps are the most recent addition to the Local History Collection in support of the library's Historic Sites Inventory (HSI) project. For more information about how to access the HSI or to inquire about donating information, contact the library at email@example.com.
