Tip of the week: Using Sanborn Maps

Share Button

Sanborn maps are a valuable research tool. These maps are fire insurance maps dating 1866-1959. Approximately 3,000 cities have Sanborn maps that cover all 50 U.S. states, Canada, and Mexico.

North Carolina maps include 145 towns within 85 counties; however, different cities have maps for different years. For example, the town of Hertford in Perquimans County has maps for the years of 1916, 1923, 1929-1940. On the other hand, Concord in Cabarrus County has maps dated 1885, 1887, 1892, 1897, 1902, 1906, 1911, 1921, and 1927.
