715 Collins first appeared in the 1912 Polk City Directory.  Charles Fisher, a clerk with C. D. Clapp, was the resident that year.  It was the home of Albert Allmendinger, a salesman, according to the 1918, 1921 and 1924 city directories.  George Allmendinger roomed here in 1924.  The 1918 and 1924 directories also listed Cora McRoy, the widow of Hugh McRoy, as an occupant of this home.
