What Are Sanborn Fire Insurance Maps?
Sanborn Maps show in great detail lots, houses, businesses, and other structures in a city's central district. These maps are also color coded to show the type of construction: concrete, wood frame, brick, etc.
Originally used by insurance agents to set fire insurance rates, Sanborn Maps help date structures, find original lot and building outlines, and locate outbuildings. By comparing maps with different publication dates, you can see how cities and neighborhoods change over the years.
