Sanborn™ Maps

The Sanborn Map Company is the oldest mapping company in the United States. Sanborn was founded in 1866 to create detailed building maps of cities and towns, primarily for use by insurance companies. These maps have been used extensively by local government agencies for over a century in conducting their daily operations efficiently.

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. (EDR). EDR is an environmental information company whose clients rely on Sanborn Maps for historical property information. The Sanborn Map Company refers all requests for historical Sanborn Maps to EDR.
