Most of Warner was built recently: 3% of its homes predate 1940 and the median home dates from 1992. Below: maps from 1985 on and the census since 1980.
Warner was established in June 1880. The town's name is derived from Warren Tarbox, a pioneer settler. Growth in Warner was primarily fueled by the expansion of the Chicago, Milwaukee, St. Paul and Pacific Railroad in 1881, and Great Northern Railway and the Minneapolis and St. Louis Railway a few years later. This is due to the next town north, Aberdeen, being where Great Northern Railway & Minneapolis and St. Louis Railway met, giving Aberdeen the nickname "hub city".
