Dating back to 1904, mapmaker is longest running, most successful in country

If you’re looking at a map, there’s a good chance it was made by the Sanborn Map Company. The company’s building, which is located on Fifth Avenue in Pelham, achieved a major milestone Wednesday.

The Sanborn Map building, which dates back to 1904, is the longest running, largest, and most successful map makers’ building in the United States.

“There were at one time 500 people sitting here drawing maps of the entire United States; it was really cool,” says Steven Caspi, owner of the Sanborn Map building.

The maps were originally created to estimate fire insurance risks and 110 years later, the map making company still calls the building home along with other Westchester-based businesses, like Archie Comics.

In honor of its birthday, Westchester County Executive Rob Astorino has proclaimed April 20 the Sanborn Map Building Day.
