More About Fire Insurance Maps

Fire Insurance Maps Online

Fire insurance maps date from 1867 to the present and depict the commercial, industrial, and residential sections of tens of thousands of cities and towns in the United States, Canada, and Mexico. Maps were designed to assist fire insurance agents to determine the degree of hazard for a property. The maps show the size, shape, and construction of dwellings, commercial buildings, and factories as well as fire walls, locations of windows and doors, sprinkler systems, and types of roofs. The maps also indicate widths and names of streets, property boundaries, building use, house and block numbers, and location of fire hydrants.

The Sanborn Maps were originally created for assessing fire insurance liability in urbanized areas in the United States. The maps include detailed information regarding town and building information in approximately 12,000 U.S. towns and cities from 1867 to 2007.  Founded in 1867 the Sanborn Map and Publishing Company was the primary American publisher of fire insurance maps for nearly 100 years. 

Great Britain Fire Insurance Maps

Goad fire insurance plans are unique primary source materials capturing what is, in many cases, otherwise undocumented information about buildings, land use and urban design. This collection of Goad plans of the British Isles are the very first editions of this mapping, representing all of the major centres of population at the turn of the twentieth century; publication dates range from 1886 to 1930.
