Sanborn® Fire Insurance Maps Online

From 1867 to 1977, the Sanborn® Map Company of Pelham, New York, produced large-scale (usually 50 feet to the inch) color maps of over 13,000 towns and cities across the United States in order to assist fire insurance companies in setting rates and terms. The color-coded Sanborn maps depict the location, dimension, height, and use of buildings, as well as the materials employed in their construction, and other relevant features. The Library of Congress web site refers to these color-coded maps as "probably the single most important record of urban growth and development in the United States during the past one hundred years."

The following online collections offer free access to digitized copies of Sanborn Fire Insurance Maps for select states, cities, and towns. Most date from the 1880s through 1921 or 1922, as more recent maps are still protected by copyright. Maps from 1923 through the 1960s are also available for many localities, but due to copyright restrictions you need to visit or contact the Library of Congress or other repositories holding Sanborn Maps for access.
