The Maher Building, also known as the Illinois Hotel, is a historic building in Vero Beach, Florida. Originally located at 1423 Osceola Boulevard, now 20th Street, the Maher Building housed the Maher department store owned by William J. and Catherine Maher. The store retained a reasonable reputation throughout the city for offering apparel at "pleasing prices". Although no lives were lost when the original store building burned down in November 1919, the tragedy resulted in its complete loss. After Maher recovered from the damages, he reordered stock from St. Louis and commissioned a new brick and concrete structure on the building's original site. On October 28, 1994, this structure was added to the U.S. National Register of Historic Places.
