Sanborn Fire Insurance Maps

These maps were created for insurance agents to determine premiums for fire insurance. They show building materials, floor plans, water availability, local hazards and much more. For genealogy, they show an outline of houses, types of businesses in the neighborhood, some topography, etc. The original maps were in color. The microfilm loses this feature. Some of these local maps are available at Cleveland Public Library and Western Reserve Historical Society. (WRHS maps show the new and old addresses, as it was an update with new buildings pasted on to the originals.)
