Fire Insurance Maps Provide Historical City Snapshots

Fire insurance maps are detailed city plans, usually at scales of 50 or 100 feet to an inch. They show individual building “footprints,” complete with construction details such as building material (brick, adobe, frame, etc.), height (of larger buildings), number of stories, location of doors, windows, chimneys and elevators, use of structure (dwelling, hotel, church, etc.), street address, and occasionally the ethnicity of the occupants. Other features shown include lot lines, street widths, water pipes, hydrants and cisterns, and fire-fighting facilities.

The Sanborn Map Company was founded in 1866 to create fire insurance maps of cities and towns.

The largest and most complete collection of historical Sanborn Maps is owned by The Sanborn Library, LLC. Copies of the Sanborn Map collection are offered through Environmental Data Resources, Inc.
